-# Manifold CLA
-
-**Manifold Markets Contributor License Agreement**
-
-(Thanks to [Beeminder](http://bmndr.co/cla) and [Discourse.org](https://cla-assistant.io/discourse/discourse) whose CLAs we modeled this on!)
-
-## Unofficial Summary
-
-- Manifold can use your contributions
-- Manifold can sell things involving your contributions
-- You’re legally able to agree to the above
-- You’re the one who created these contributions
-- Manifold decides what gets included in Manifold
-- Manifold does not promise any support
-
-## Official Agreement
-
-The document below clarifies the terms under which You (the copyright owner or legal entity authorized by the copyright owner), may make "The Contributions" (software, bug fixes, configuration changes, documentation, or any other materials) to "The Work" (Manifold Markets). This license protects You, "The Company" (Manifold Markets, Inc.) and licensees; it does not change your rights to use your own contributions for any other purpose.
-
-You and "The Company" (Manifold Markets, Inc.) agree:
-
-- You grant to "The Company" (Manifold Markets, Inc.) a non-exclusive, irrevocable, worldwide, royalty-free, sublicenseable, relicenseable, transferable license under all of Your relevant intellectual property rights, to use, copy, prepare derivative works of, distribute and publicly perform and display "The Contributions" on any licensing terms, including without limitation: (a) open source licenses like the GNU General Public (v2.0) license; and (b) binary, proprietary, or commercial licenses. Except for the licenses granted herein, You reserve all right, title, and interest in and to "The Contributions".
-- You grant to "The Company" a non-exclusive, irrevocable (except as stated in this section), worldwide, royalty-free, sublicenseable, transferable patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer "The Work", where such license applies only to those patent claims licensable by You that are necessarily infringed by Your Contribution(s) alone or by combination of Your Contribution(s) with "The Work" to which such Contribution(s) was submitted. If any entity institutes patent litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that your Contribution, or "The Work" to which you have contributed, constitutes direct or contributory patent infringement, then any patent licenses granted to that entity under this Agreement for that Contribution or Work shall terminate as of the date such litigation is filed.
-- You are able to grant us these rights. You represent that You are legally entitled to grant the above license(s). If Your employer has rights to intellectual property that You create, You represent that You have received permission to make "The Contributions" on behalf of that employer, or that Your employer has waived such rights for "The Contributions".
-- "The Contributions" are your original work. You represent that "The Contributions" are Your original works of authorship, and to Your knowledge, no other person claims, or has the right to claim, any right in any invention or patent related to "The Contributions". You also represent that You are not legally obligated, whether by entering into an agreement or otherwise, in any way that conflicts with the terms of this license. For example, if you have signed an agreement requiring you to assign the intellectual property rights in "The Contributions" to an employer or customer, that would conflict with the terms of this license.
-- We, as authoritative representatives of "The Company" determine the code that is in "The Work". You understand that the decision to include "The Contribution(s)" in any project or source repository is entirely that of "The Company", and this agreement does not guarantee that "The Contributions" will be included in any product.
-- No Implied Warranties. "The Company" acknowledges that, except as explicitly described in this Agreement, the Contribution is provided on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE.

-# Manifold Markets
+# mantic
 
-This [monorepo][] has basically everything involved in running and operating Manifold.
-
-## Getting started
-
-0. Make sure you have [Yarn 1.x][yarn]
-1. `$ cd web`
-2. `$ yarn`
-3. `$ yarn dev:dev`
-4. Your site will be available on http://localhost:3000
-
-See [`web/README.md`][web-readme] for more details on hacking on the web client.
-
-## General architecture
-
-Manifold's public API and web app are hosted by [Vercel][vercel]. In general, the web app runs as much as possible on the client; we follow a [JAMStack][jamstack] architecture. All data is stored in Firebase's database, [Cloud Firestore][cloud-firestore]. This is directly accessed by the client for most data access operations.
-
-Operations with complicated contracts (e.g. buying shares) are provided in a separate HTTP API using Firebase's [Cloud Functions][cloud-functions]. Those are deployed separately from the Vercel website; see [`functions/README.md`][functions-readme] for more details.
-
-## Directory overview
-
-- `web/`: UI and business logic for the client. Where most of the site lives. The public API endpoints are also in here.
-
-- `functions/`: Firebase cloud functions, for secure work (e.g. balances, Stripe payments, emails). Also contains in
-  `functions/src/scripts/` some Typescript scripts that do ad hoc CLI interaction with Firebase.
-
-- `common/`: Typescript library code shared between `web/` & `functions/`. If you want to look at how the market math
-  works, most of that's in here (it gets called from the `placeBet` and `sellBet` endpoints in `functions/`.) Also
-  contains in `common/envs` configuration for the different environments (i.e. prod, dev, Manifold for Teams instances.)
-
-- `og-image/`: The OpenGraph image generator; creates the preview images shown on Twitter/social media.
-
-- `docs/`: Manifold's public documentation that lives at https://docs.manifold.markets.
-
-## Contributing
-
-Since we are just now open-sourcing things, we will see how things go. Feel free to open issues, submit PRs, and chat about the process on [Discord][discord]. We would prefer [small PRs][small-prs] that we can effectively evaluate and review -- maybe check in with us first if you are thinking to work on a big change.
-
-By contributing to this codebase, you are agreeing to the terms of the [Manifold CLA](https://github.com/manifoldmarkets/manifold/blob/main/.github/CONTRIBUTING.md).
-
-If you need additional access to any infrastructure in order to work on something (e.g. Vercel, Firebase) let us know about that on [Discord][discord] as well.

-    description: `1Day Sooner is a non-profit that advocates on behalf of COVID-19 challenge trial volunteers.
-      
-    After a vaccine candidate is created in a lab, it is developed through a combination of pre-clinical evaluation and three phases of clinical trials that test its safety and efficacy. In traditional Phase III trials, participants receive the vaccine candidate or a placebo/active comparator, and efficacy is judged by comparing the prevalence of infection in the vaccine group and the placebo/comparator group, to test the hypothesis that significantly fewer participants in the vaccine group get infected. In these traditional trials, after receiving the treatment, participants return to their homes and their normal daily lives so as to test the treatment under real world conditions. Since only a small proportion of these participants may encounter the disease, it may take a large number of participants and a good deal of time for these trials to reveal differences between the vaccine and placebo groups.
-      
-    In a human challenge trial (HCT), willing participants would receive the vaccine candidate or placebo and, after some time for the vaccine to take effect, be deliberately exposed to live coronavirus. Since exposure to the virus is guaranteed in HCTs, it may be possible to judge a vaccine candidate’s efficacy more quickly and with far fewer participants than a standard Phase III trial. While HCT efficacy results do not traditionally provide sufficient basis for licensure on their own, they could allow us to (1) more quickly weed out disappointing vaccine candidates or (2) promote the development of promising candidates in conjunction with traditional Phase III studies.
-      
-    In addition, by gathering detailed data on the process of infection and vaccine protection in a clinical setting, researchers could learn information that proves extremely useful for broader vaccine and therapeutic development efforts. Altogether, there are scenarios in which the speed of HCTs and the richness of the data they provide accelerate the development of an effective and broadly accessible COVID-19 vaccine, with thousands of lives spared (depending on the pandemic’s long-term trajectory).`,

-    description: `ARC is a non-profit research organization whose mission is to align future machine learning systems with human interests. Its current work focuses on developing an alignment strategy that could be adopted in industry today while scaling gracefully to future ML systems. Right now Paul Christiano and Mark Xu are researchers and Kyle Scott handles operations.
-
-What is “alignment”? ML systems can exhibit goal-directed behavior, but it is difficult to understand or control what they are “trying” to do. Powerful models could cause harm if they were trying to manipulate and deceive humans. The goal of intent alignment is to instead train these models to be helpful and honest.
-
-Motivation: We believe that modern ML techniques would lead to severe misalignment if scaled up to large enough computers and datasets. Practitioners may be able to adapt before these failures have catastrophic consequences, but we could reduce the risk by adopting scalable methods further in advance.
-
-What we’re working on: The best way to understand our research priorities and methodology is probably to read our report on Eliciting Latent Knowledge. At a high level, we’re trying to figure out how to train ML systems to answer questions by straightforwardly “translating” their beliefs into natural language rather than by reasoning about what a human wants to hear.
-
-Methodology: We’re unsatisfied with an algorithm if we can see any plausible story about how it eventually breaks down, which means that we can rule out most algorithms on paper without ever implementing them. The cost of this approach is that it may completely miss strategies that exploit important structure in realistic ML models; the benefit is that you can consider lots of ideas quickly. (More)
-
-Future plans: We expect to focus on similar theoretical problems in alignment until we either become more pessimistic about tractability or ARC grows enough to branch out into other areas. Over the long term we are likely to work on a combination of theoretical and empirical alignment research, collaborations with industry labs, alignment forecasting, and ML deployment policy.`,

-    description: `Over the last few decades, scientific and technological progress have stagnated. Scientists conduct more research than ever before, but groundbreaking innovation is scarce. At the same time, identity politics and political polarization have reached new extremes, and social trends such as family stability and crime are worse than in previous decades and in some cases moving in the wrong direction. What explains these trends, and how can we reverse them?
-
-    Much of the blame lies with the institutions we rely on for administration, innovation, and leadership. Instead of forward-looking governments, we have short-sighted politicians and bloated bureaucracies. Instead of real experts with proven track records, we have so-called ‘experts’ who appeal to the authority of their credentials. Instead of political leaders willing to face facts and make tough tradeoffs, we have politicians who appeal to ignorance and defer responsibility.
-    
-    To fix our institutions, we need to rethink them from the ground up. That is why CSPI supports and funds research into the administrative systems, organizational structures, and political ideologies of modern governance. Only by understanding what makes these systems so often dysfunctional can we change them for the better.
-    
-    CSPI believes that governments should be accountable to the populace as a whole, not special interest groups. We think experts should have greater say in public policy, but that there should be different standards for what qualifies as “expertise.” We want to end scientific and technological stagnation and usher in a new era of growth and innovation.
-    
-    We are interested in funding and supporting research that can speak to these issues in the social sciences through grants and fellowships. CSPI particularly seek outs work that is unlikely to receive support elsewhere. See our home page for more about the kinds of research we are particularly interested in funding.`,

-    description: `Although the natural world is a source of great beauty and happiness, vast numbers of animals routinely face serious challenges such as disease, hunger, or natural disasters. There is no “one-size-fits-all” solution to these threats. However, even as we recognize that improving the welfare of free-ranging wild animals is difficult, we believe that humans have a responsibility to help whenever we can.
-
-Our staff explores how humans can beneficially coexist with animals through the lens of wild animal welfare. 
-
-We respect wild animals as individuals with their own needs and preferences, rather than seeing them as mere parts of ecosystems. But this approach demands a richer understanding of wild animals’ lives. 
-
-We want to take a proactive approach to managing the welfare benefits, threats, and uncertainties that are inherent to complex natural and urban environments. Yet, to take action safely, we must conduct research to understand the impacts of our actions. The transdisciplinary perspective of wild animal welfare draws upon ethics, ecology, and animal welfare science to gather the knowledge we need, facilitating evidence-based improvements to wild animals’ quality of life.
-
-Without sufficient public interest or research activity, solutions to the problems wild animals face will go undiscovered. 
-
-Wild Animal Initiative currently focuses on helping scientists, grantors, and decision-makers investigate important and understudied questions about wild animal welfare. Our work catalyzes research and applied projects that will open the door to a clearer picture of wild animals’ needs and how to enhance their well-being. Ultimately, we envision a world in which people actively choose to help wild animals — and have the knowledge they need to do so responsibly.`,

-    THREE THINGS TO KNOW ABOUT THE ACLU
-•	We protect American values. In many ways, the ACLU is the nation's most conservative organization. Our job is to conserve America's original civic values - the Constitution and the Bill of Rights - and defend the rights of every man, woman and child in this country.
-•	We're not anti-anything. The only things we fight are attempts to take away or limit your civil liberties, like your right to practice any religion you want (or none at all); or to decide in private whether or not to have a child; or to speak out - for or against - anything at all; or to be treated with equality and fairness, no matter who you are.
-•	We're there for you. Rich or poor, straight or gay, black or white or brown, urban or rural, pious or atheist, American-born or foreign-born, able-bodied or living with a disability. Every person in this country should have the same basic rights. And since our founding in 1920, we've been working hard to make sure no one takes them away.
-
-The American Civil Liberties Union is our nation's guardian of liberty, working daily in courts, legislatures and communities to defend and preserve the individual rights and liberties that the Constitution and laws of the United States guarantee everyone in this country.
-
-"So long as we have enough people in this country willing to fight for their rights, we'll be called a democracy," ACLU Founder Roger Baldwin said.
-
-The U.S. Constitution and the Bill of Rights trumpet our aspirations for the kind of society that we want to be. But for much of our history, our nation failed to fulfill the promise of liberty for whole groups of people.`,

-    description: `Founded in 2011, The Center for Election Science is a national, nonpartisan nonprofit focused on voting reform.
-
-Our Mission — To empower people with voting methods that strengthen democracy.
-
-Our Vision — A world where democracies thrive because voters’ voices are heard.
-
-With an emphasis on approval voting, we bring better elections to people across the country through both advocacy and research.
-
-The movement for a better way to vote is rapidly gaining momentum as voters grow tired of election results that don’t represent the will of the people. In 2018, we worked with locals in Fargo, ND to help them become the first city in the U.S. to adopt approval voting. And in 2020, we helped grassroots activists empower the 300k people of St. Louis, MO with stronger democracy through approval voting.`,

Despite the average American household being richer than 90% of the rest of the world, only 6% of US charitable giving goes to charities which work internationally.
-
-This Fund is focused on helping those who need it most, wherever that help can make the biggest difference. By building a mixed portfolio of direct and indirect interventions, such as policy work, we aim to:
-
-Improve the lives of the world's most vulnerable people.
-Reduce the number of easily preventable deaths worldwide.

-# How to Manifold
-
-Manifold Markets is a novel site where users can bet against each other to predict the outcomes of all types of questions. Engage in intense discussion, or joke with friends, whilst putting play-money where your mouth is.
-
-## Mana
-
-Mana (M$) is our virtual play currency that cannot be converted to real money.
-
-- **Its Value**
-
-  You can redeem your Mana and we will [donate to a charity](https://manifold.markets/charity) on your behalf. Redeeming and purchasing Mana occurs at a rate of M$100 to $1. You will be able to redeem it for merch and other cool items soon too!
-
-- **It sets us apart**
-
-  Using play-money sets us apart from other similar sites as we don’t want our users to solely focus on monetary gains. Instead we prioritize providing value in the form of an enjoyable experience and facilitating a more informed world through the power of prediction markets.
-
-## How probabilities work
-
-The probability of a market represents what the collective bets of users predict the chances of an outcome occurring is. How this is calculated depends on the type of market - see below!
-
-## Types of markets
-
-There are currently 3 types of markets: Yes/No (binary), Free response, and Numerical.
-
-- **Yes/No (Binary)**
-
-  The creator asks a question where traders can bet yes or no.
-
-  Check out [Maniswap](https://www.notion.so/Maniswap-ce406e1e897d417cbd491071ea8a0c39) for more info on its automated market maker.
-
-- **Free Response**
-
-  The creator asks an open ended question. Both the creator and users can propose answers which can be bet on. Don’t be intimidated to add new answers! The payout system and initial liquidity rewards users who bet on new answers early. The algorithm used to determine the probability and payout is complicated but if you want to learn more check out [DPM](https://www.notion.so/DPM-b9b48a09ea1f45b88d991231171730c5).
-
-- **Numerical**
-
-  Retracted whilst we make improvements. You still may see some old ones floating around though. Questions which can be answered by a number within a given range. Betting on a value will cause you to buy shares from ‘buckets’ surrounding the number you choose.
-
-## Compete and build your portfolio
-
-Generate profits to prove your expertise and shine above your friends.
-
-To the moon 🚀
-
-- **Find inaccurate probabilities**
-
-  Use your superior knowledge on topics to identify markets which have inaccurate probabilities. This gives you favorable odds, so bet accordingly to shift the probability to what you think it should be.
-
-- **React to news**
-
-  Markets are dynamic and ongoing events can drastically affect what the probability should look like. Be the keenest to react and there is a lot of Mana to be made.
-
-- **Buy low, sell high**
-
-  Similar to a stock market, probabilities can be overvalued and undervalued. If you bet (buy shares) at one end of the spectrum and subsequently other users buy even more shares of that same type, the value of your own shares will increase. Sometimes it will be most profitable to wait for the market to resolve but often it can be wise to sell your shares and take the immediate profits. This can also be a great way to free up Mana if you are lacking funds.
-
-- **Create innovative answers**
-
-  Certain free response markets provide room for creativity! The answers themselves can often affect the outcome based on how compelling they are.

-# About Manifold Markets
-
-Manifold Markets lets anyone create a prediction market on any topic. Win virtual play money betting on what you know, from **[chess tournaments](https://manifold.markets/SG/will-magnus-carlsen-lose-any-regula)** to **[lunar collisions](https://manifold.markets/Duncan/will-the-wayward-falcon-9-booster-h)** to **[newsletter subscriber rates](https://manifold.markets/Nu%C3%B1oSempere/how-many-additional-subscribers-wil)** - or learn about the future by creating your own market!
-
-### **What are prediction markets?**
-
-**Prediction markets are a place where you can bet on the outcome of future events.**
-
-Consider a question like: "Will Democrats win the 2024 US presidential election?"
-
-If I think the Democrats are very likely to win, and you disagree, I might offer $70 to your $30 (with the winner taking home $100 total). This set of bets imply a 70% probability of the Democrats winning.
-
-Now, you or I could be mistaken and overshooting the true probability one way or another. If so, there's an incentive for someone else to bet and correct it! Over time, the implied probability will converge to the **[market's best estimate](https://en.wikipedia.org/wiki/Efficient-market_hypothesis)**. Since these probabilities are public, anyone can use them to make better decisions!
-
-### **Can prediction markets work without real money?**
-
-Yes! There is substantial evidence that play-money prediction markets provide real predictive power. Examples include **[sports betting](http://www.electronicmarkets.org/fileadmin/user_upload/doc/Issues/Volume_16/Issue_01/V16I1_Statistical_Tests_of_Real-Money_versus_Play-Money_Prediction_Markets.pdf)** and internal prediction markets at firms like **[Google](https://www.networkworld.com/article/2284098/google-bets-on-value-of-prediction-markets.html)**.
-
-Our overall design also ensures that good forecasting will come out on top in the long term. In the competitive environment of the marketplace, bettors that are correct more often will gain influence, leading to better-calibrated forecasts over time.
-
-Since our launch, we've seen hundreds of users trade each day, on over a thousand different markets! You can track the popularity of our platform at **[https://manifold.markets/stats](https://manifold.markets/stats)**.
-
-### **Why is this important?**
-
-Prediction markets aggregate and reveal crucial information that would not otherwise be known. They are a bottom-up mechanism that can influence everything from politics, economics, and business, to scientific research and education.
-
-Prediction markets can predict **[which research papers will replicate](https://www.pnas.org/content/112/50/15343)**; which drug is the most effective; which policy would generate the most tax revenue; which charity will be underfunded; or which startup idea is the most promising. By surfacing and quantifying our collective knowledge, we as a society become wiser.
-
-### **How are markets resolved?**
-
-The creator of the prediction market decides the outcome and earns a commission based on the trade volume.
-
-This simple resolution mechanism has surprising benefits in allowing a diversity of views to flourish. Competition between market creators will lead to traders flocking to the creators with good judgment on market resolution.
-
-What's more, when the creator is free to use their judgment, many new kinds of prediction markets can be created that are less objective or even personal. (E.g. "Will I enjoy participating in the Metaverse in 2023?")
-
-<!-- ### **Can I create private markets?**
-
-Soon! We're running a pilot version of Manifold for Teams - private Manifold instances where you can discuss internal topics and predict on outcomes for your organization.
-
-If this sounds like something you’d want, **[join the waitlist here](https://docs.google.com/forms/d/e/1FAIpQLSfM_rxRHemCjKE6KPiYXGyP2nBSInZNKn_wc7yS1-rvlLAVnA/viewform?usp=sf_link)**! -->
-
-### **Who are we?**
-
-Manifold Markets is currently a team of three:
-
-- James Grugett
-- Stephen Grugett
-- Austin Chen
-
-We've previously launched consumer-facing startups (**[Throne](https://throne.live/)**, **[One Word](https://oneword.games/platform)**), and worked at top tech and trading firms (Google, Susquehanna).

-# API
-
-:::caution
-
-Our API is still in alpha — things may change or break at any time!
-
-If you have questions, come chat with us on [Discord](https://discord.com/invite/eHQBNBqXuh). We’d love to hear about what you build!
-
-:::
-
-## General notes
-
-Some APIs are not associated with any particular user. Other APIs require authentication.
-
-APIs that require authentication accept an `Authorization` header in one of two formats:
-
-- `Authorization: Key {key}`. A Manifold API key associated with a user
-  account. Each account may have zero or one API keys. To generate an API key
-  for your account, visit your user profile, click "edit", and click the
-  "refresh" button next to the API key field at the bottom. You can click it
-  again any time to invalidate your existing key and generate a new one.
-
-- `Authorization: Bearer {jwt}`. A signed JWT from Firebase asserting your
-  identity. This is what our web client uses. It will probably be annoying for
-  you to generate and we will not document it further here.
-
-API requests that accept parameters should either have the parameters in the
-query string if they are GET requests, or have a body with a JSON object with
-one property per parameter if they are POST requests.
-
-API responses should always either have a body with a JSON result object (if
-the response was a 200) or with a JSON object representing an error (if the
-response was a 4xx or 5xx.)
-
-## Endpoints
-
-### `GET /v0/user/[username]`
-
-Gets a user by their username. Remember that usernames may change.
-
-Requires no authorization.
-
-### `GET /v0/user/by-id/[id]`
-
-Gets a user by their unique ID. Many other API endpoints return this as the `userId`.
-
-Requires no authorization.
-
-### GET /v0/me
-
-Returns the authenticated user.
-
-### `GET /v0/groups`
-
-Gets all groups, in no particular order.
-
-Parameters:
-
-- `availableToUserId`: Optional. if specified, only groups that the user can
-  join and groups they've already joined will be returned.
-
-Requires no authorization.
-
-### `GET /v0/group/[slug]`
-
-Gets a group by its slug.
-
-Requires no authorization.
-Note: group is singular in the URL.
-
-### `GET /v0/group/by-id/[id]`

-
-### `POST /v0/bet`
-
-Places a new bet on behalf of the authorized user.
-
-Parameters:
-
-- `amount`: Required. The amount to bet, in M$, before fees.
-- `contractId`: Required. The ID of the contract (market) to bet on.
-- `outcome`: Required. The outcome to bet on. For binary markets, this is `YES`
-  or `NO`. For free response markets, this is the ID of the free response
-  answer. For numeric markets, this is a string representing the target bucket,
-  and an additional `value` parameter is required which is a number representing
-  the target value. (Bet on numeric markets at your own peril.)
-- `limitProb`: Optional. A number between `0.001` and `0.999` inclusive representing
-  the limit probability for your bet (i.e. 0.1% to 99.9% — multiply by 100 for the
-  probability percentage).
-  The bet will execute immediately in the direction of `outcome`, but not beyond this
-  specified limit. If not all the bet is filled, the bet will remain as an open offer
-  that can later be matched against an opposite direction bet.
-  - For example, if the current market probability is `50%`:
-    - A `M$10` bet on `YES` with `limitProb=0.4` would not be filled until the market
-      probability moves down to `40%` and someone bets `M$15` of `NO` to match your
-      bet odds.
-    - A `M$100` bet on `YES` with `limitProb=0.6` would fill partially or completely
-      depending on current unfilled limit bets and the AMM's liquidity. Any remaining
-      portion of the bet not filled would remain to be matched against in the future.
-  - An unfilled limit order bet can be cancelled using the cancel API.
-
-Example request:
-
-```
-$ curl https://manifold.markets/api/v0/bet -X POST -H 'Content-Type: application/json' \
-    -H 'Authorization: Key {...}' \
-    --data-raw '{"amount":1, \

-```
-
-### `POST /v0/bet/cancel/[id]`

-
-Example request:
-
-```
-$ curl https://manifold.markets/api/v0/market -X POST -H 'Content-Type: application/json' \
-    -H 'Authorization: Key {...}'

-
-For numeric markets:
-
-- `outcome`: Required. One of `CANCEL`, or a `number` indicating the selected numeric bucket ID.
-- `value`: The value that the market may resolves to.
-- `probabilityInt`: Required if `value` is present. Should be equal to

-# Community FAQ
-
-## General
-
-### Do I have to pay real money in order to participate?
-
-Nope! Each account starts with a free 1000 mana (or M$1000 for short). If you invest it wisely, you can increase your total without ever needing to put any real money into the site.
-
-### Can M$ be sold for real money?
-
-No. Gambling laws put many restrictions on real-money prediction markets, so Manifold uses play money instead.
-
-You can instead redeem your Mana and we will [donate to a charity](http://manifold.markets/charity) on your behalf. Redeeming and purchasing Mana occurs at a rate of M$100 to $1.
-
-### How do the free response markets work?
-
-Any user can enter a response and bet on it, or they can bet on other people's responses. The response probabilities are weighted proportionally to how many people have bet on them. The market creator's ante goes into a "none of the above" pseudo-option that can't be bet on and can't be chosen as a correct answer when the market is resolved. (This means that free response markets tend to lose their creator almost their entire ante. It also means that if there are only a finite number of options that could win, traders can make guaranteed money by investing in them all equally.) See [here](https://manifoldmarkets.substack.com/p/above-the-fold-milestones-and-new) for more information.
-
-### How accurate are the market probabilities?
-
-In general, prediction markets are very accurate. They do have some known issues, most of which can be found on the [Wikipedia page.](https://en.wikipedia.org/wiki/Prediction_market#Accuracy). There are also a few factors that are specific to Manifold Markets:
-
-- Manifold uses play money for their markets, so there's less of an incentive for people to invest safely. People often goof around with silly markets and investments that they don't expect to win M$ from.
-- Anyone can create a market on Manifold, and there's nothing preventing the creator of a market from trying to manipulate it to make a profit.
-- Manifold Markets is a new project and has a large number of individual markets, which means that many of their markets don't have many participants, sometimes less than 5 people.
-- Manifold's betting system isn't perfect and has some sources of error, discussed in detail [here](https://kevin.zielnicki.com/2022/02/17/manifold/).
-
-As a general heuristic, check the total pool for the market in question. The more M$ there is in the market, the more likely it is to be accurate.
-
-### Can I participate without having a Google account?
-
-No. See [here](https://manifold.markets/hamnox/will-manifold-markets-add-nongoogle) for the probability that this changes.
-
-## Placing and winning bets
-
-### The payout probabilities I'm shown sometimes aren't right. For example if a market is at 15% and I bet M$1 on "no", it tells me that I'll make a 42% profit if I win, but the listed payout is just M$1. What's going on?
-
-Payout amounts are visually rounded to the nearest M$1, and only integer amounts can be put into markets. Behind the scenes however, your balance does track fractional amounts, so you're making a M$0.42 profit on that bet. Once you win another M$0.08, that fractional M$0.5 will display as an extra M$1 in your account. (There's no way to view your exact balance, you can only see the rounded value.)
-
-### What are the rules about insider trading? (Using private information about a market to make a profit.)
-
-It's not only allowed, but encouraged. The whole point of a prediction market is to uncover and amplify this sort of hidden information. For example, if there's a market like "will [company] make [decision]?" and you work for that company and know what decision they're going to make, you can use that information to win M$ and make the market more accurate at the same time. (Subject to your company's policies on disclosing internal information of course.) However, if the reason you have private information is because you're colluding with the market creator, this will likely earn both of you a bad reputation and people will be less interested in participating in your markets in the future.
-
-### Can I see who is buying/selling in a market?
-
-All trades before June 1, 2022 are anonymous by default. Trades after that date can be viewed in the Bets tab of any market, and also on that user's profile.
-
-## Creating and resolving markets
-
-### Is there any benefit to creating markets?
-
-You get your question answered! Plus, you earn a commission on trades in your markets.
-
-### What can I create a market about?
-
-Anything you want to! People ask about politics, science, gaming, and even [their personal lives](https://www.smbc-comics.com/?id=2418). Take a look at the [current list of markets](https://manifold.markets/markets) to see what sorts of things people ask about.
-
-### What's the difference between a market being "closed" and being "resolved"?
-
-A market being "closed" means that people can no longer place or sell bets, "locking in" the current probability. Markets close when the close date of the market is met. A market being "resolved" means that the market creator has indicated a given resolution to the market's question, such as "yes", "no", "N/A", or a certain probability. This is the point at which people are cashed out of the market. Resolving a market automatically closes it, but a market can close days, weeks, or even years before it gets resolved.
-
-### What does "PROB" mean?
-
-Resolving a market as "PROB" means that it's resolved at a certain probability, chosen by the market creator. PROB 100% is the same as "yes", and PROB 0% is the same as "no". For example, if a market is resolved at PROB 75%, anyone who bought "yes" at less than 75% will (usually) make a profit, and anyone who bought "yes" at greater than 75% will (usually) take a loss. Vice versa for "no". This is also shown as "MKT" in the interface and API.
-
-### What happens if a market creator resolves a market incorrectly, or doesn't resolve it at all?
-
-Nothing. The idea is for Manifold Markets to function with similar freedom and versatility to a Twitter poll, but with more accurate results due to the dynamics of prediction markets. Individual market resolution is not enforced by the site, so if you don't trust a certain user to judge their markets fairly, you probably shouldn't participate in their markets.
-
-That being said, manifold staff may manually send reminder emails to the creators of large markets if they have not been resolved in some time. There are also some projects in the works to enable automated market resolution after some time has passed.
-
-### How do I tell if a certain market creator is trustworthy?
-
-Look at their market resolution history on their profile page. If their past markets have all been resolved correctly, their future ones probably will be too. You can also look at the comments on those markets to see if any traders noticed anything suspicious. You can also ask about that person in the [Manifold Markets Discord](https://discord.gg/eHQBNBqXuh). And if their profile links to their website or social media pages, you can take that into account too.
-
-### Are there any content filters? What happens if someone creates an inappropriate, offensive, or [dangerous](https://en.wikipedia.org/wiki/Assassination_market) market?
-
-Right now, there are no restrictions on what markets can be created. If this becomes a problem, they may change their policies.
-
-### Can a market creator change the close date of their market?
-
-Yes. As long as the market hasn't been resolved yet, the creator can freely change its close date. They can even reopen a market that has already closed.
-
-### Is there a way to see my closed markets that I need to resolve?
-
-You'll get an automated email when they close. You can also go to your profile page and select "closed" in the dropdown menu. (This will display only markets that you haven't resolved yet.)
-
-### When do market creators get their commission fees?
-
-When the creator resolves their market, they get the commission from all the trades that were executed in the market.
-
-### How do I see markets that are currently open?
-
-You can see the top markets in various categories [here](https://manifold.markets/markets).
-
-### Can I bet in a market I created?
-
-Yes. However if you're doing things that the community would perceive as "shady", such as putting all your money on the correct resolution immediately before closing the market, people may be more reluctant to participate in your markets in the future. Betting "normally" in your own market is fine though.
-
-## Miscellaneous
-
-### How do I report bugs or ask for new features?
-
-Contact them via [email](mailto:info@manifold.markets), post in their [Discord](https://discord.gg/eHQBNBqXuh), or create a market about that bug/feature in order to draw more attention to it and get community input.
-
-If you don't mind putting in a little work, fork the code and open a [pull request](https://github.com/manifoldmarkets/manifold/pulls) on GitHub.
-
-### How can I get notified of new developments?
-
-Being a very recent project, Manifold is adding new features and tweaking existing ones quite frequently. You can keep up with changes by subscribing to their [Substack](https://manifoldmarkets.substack.com/), or joining their [Discord server](https://discord.gg/eHQBNBqXuh).
-
-### Is there an app?
-
-No, but the website is designed responsively and looks great on mobile.
-
-### Does Manifold have an API for programmers?
-
-Yep. Documentation is [here](https://docs.manifold.markets/api).
-
-### If I have a question that isn't answered here, where can I ask it?
-
-You can contact Manifold Markets via [email](mailto:info@manifold.markets) or post in their [Discord](https://discord.gg/eHQBNBqXuh). Once you have an answer, please consider updating this FAQ via "Edit this page" on Github!

-# Guide to Market Types
-
-# Market Mechanisms
-
-Historically, Manifold used a special type of automated market maker based on a dynamic pari-mutuel (DPM) betting
-system. Free response and numeric markets still use this system. Binary markets created prior to March 15, 2022 used
-this system, but all of those markets have since closed.
-
-Binary markets created after March 15 use a constant-function market maker which holds constant the weighted geometric
-mean, with weights equal to the probabilities chosen by the market creator at creation. This design was inspired by
-Uniswap's CPMM and a suggestion from Manifold user Pepe. The benefit of this approach is that the payout for any bet 
-is fixed at purchase time - 100 shares of YES will always return M$100 if YES is chosen.
-
-Free response markets (and the depreciated numeric markets) still use the DPM system, as they have discrete "buckets"
-for the pool to be sorted into.
-
-## Market Creation
-
-- Users can create a market on any question they want.
-- When a user creates a market, they must choose a close date, after which trading will halt.
-- They must also pay a M$100 market creation fee, which is used as liquidity to subsidize trading on the market.
-- The market creator will earn a commission on all bets placed in the market.
-- The market creator is responsible for resolving each market in a timely manner. All fees earned as a commission will be paid out after resolution.
-- Creators can also resolve N/A to cancel all transactions and reverse all transactions made on the market - this includes profits from selling shares.
-
-# Binary Markets
-
-## Binary Markets: Overview
-
-- Binary markets are structured around a question with a binary outcome, such as:
-  - [Will Bitcoin be worth more than $60,000 on Jan 1, 2022 at 12 am ET?](https://manifold.markets/SG/will-bitcoin-be-worth-more-than-600)
-  - [Will Manifold Markets have over $1M in revenue by Jan 1st, 2023?](https://manifold.markets/ManifoldMarkets/will-mantic-markets-have-over-1m)
-  - [Will we discover life on Mars before 2024?](https://manifold.markets/LarsDoucet/will-we-discover-life-on-mars-befor)
-- Some binary markets are used as quasi-numeric markets, such as:
-  - [How many additional subscribers will my newsletter have by the end of February?](https://manifold.markets/Nu%C3%B1oSempere/how-many-additional-subscribers-wil)
-  - [How many new signups will Manifold have at the end of launch day?](https://manifold.markets/ManifoldMarkets/how-many-new-signups-will-manifold)
-  - [What day will US Covid deaths peak in February?](https://manifold.markets/JamesGrugett/what-day-will-us-covid-deaths-peak)
-  - These markets are made possible by the MKT option described below.
-
-## Binary Markets: Betting & Payouts
-
-- Traders can place a bet on either YES or NO and receive shares in the outcome in return.
-- Betting on YES will increase the market’s implied probability; betting on NO will decrease the probability.
-- Manifold's automated market automatically adjusts the market probability after each trade and determines how many shares a user will get for their bet.
-- You can sell back your shares for cash. If you sell YES shares, the market probability will go down. If you sell NO shares, the probability will go up.
-- 1 YES share = M$1 if the event happens. 1 NO share = M$1 if the event does not happen.
-  - Notice that 1 YES share + 1 NO share = M$1. If you ever get multiple YES and NO shares, they will cancel out and you will be left with cash.
-- When the market is resolved, you will be paid out according to your shares. If you own 100 YES shares, if the event resolves YES, you will earn M$100. (If the event resolves NO, you will earn M$0).
-- The creator of each market is responsible for resolving each market. They can resolve to YES, NO, MKT, or N/A.
-  - Resolving to MKT allows the creator to choose a percentage. The payout for any YES share is multiplied by this percentage, and vice versa for NO.
-    - For example, if a market resolves to MKT at 30%, if you have 100 shares of YES you will receive `M$100 * 30% = M$30`.
-    - In the same situation as above, if you have 100 shares of NO you will receive `M$100 * (100% - 30%) = M$70`.
-    - Note that even in this instance, 1 YES share plus 1 NO share still equals M$1.
-
-## Binary Markets: Liquidity
-
-- The liquidity in a market is the amount of capital available for traders to trade against. The more liquidity, the greater incentive there is for traders to bet, and the more accurate the market should be.
-- When a market is created, the creation fee (also called the ante or subsidy) is used to fill the liquiity pool. This happens whether the creation fee is paid by the user or by Manifold for the daily free market.
-- Behind the scenes, when a bet is placed the CPMM mechanism does [a bunch of math](http://bit.ly/maniswap). The end result is that for each M$1 bet, 1 YES share and 1 NO share is created. Some amount of shares are then given to the user who made the bet, and the rest are stored in the liquidity pool.
- Due to this mechansim, the number of YES shares in the whole market always equals the number of NO shares.
-- You can manually add liquidity to any market to increase the incentives for traders to participate. You can think of added liquidity as a subsidy for getting your question answered. You can do this by opening up the market info popup window located in the (...) section of the header on the market page.
-  - Adding liquidity provides you with a number of YES and NO shares, which can be withdrawn from the same interface. These shares resolve to M$ like normal when the market resolves, which will return you some amount of your investment. 
-  - If the market moves significantly in either direction, your liquidity will become significantly less valuable. You are currently very unlikely to make money by investing liquidity in a market, it is a way to subsidize a market and encourage more people to bet, to achieve a more accurate answer. 
-  - Adding liquidity to a market also makes it require more capital to move the market, so if you want to subsidize a market, first make sure the market price is roughly where you think it should be.
-
-# Free-Response Markets
-
-## Free-Response Markets: Overview
-
-- Free-response markets are structured around a question with a multiple outcomes, such as:
-  - [Which team will win the NBA Finals 2022?](https://manifold.markets/howtodowtle/which-team-will-win-the-nba-finals)
-  - [Who will win "Top Streaming Songs Artist" at the 2022 Billboard Music Awards?](https://manifold.markets/Predictor/who-will-win-top-streaming-songs-ar)
-  - [What life improvement intervention suggested would I found most useful?](https://manifold.markets/vlad/what-life-improvement-intervention)
-- Some free-response markets are used as quasi-numeric markets, such as:
-  - [What day will Russia invade Ukraine?](https://manifold.markets/Duncan/what-day-will-russia-invade-ukraine)
-  - [What will inflation be in March?](https://manifold.markets/ManifoldMarkets/what-will-inflation-be-in-march)
-  - [How many Manifold team members in the Bahamas will test positive for COVID?](https://manifold.markets/Sinclair/how-many-manifold-team-members-in-t)
-
-## Free-Response Markets: Betting & Payouts
-
-- Markets are structured around a list of answers, any of which can be bet on.
-- When a Free Response market is created, the market creation fee goes into a hidden answer called the Ante and gets paid to the winner(s), to subsidize the market and create an incentive to bet. This happens whether the creation fee is paid by the user or by Manifold for the daily free market.
-  - This hidden answer is why a market's probabilities will not add up to 100%. 
-  - If you want to further subsidize a market, it's customary to create an ANTE answer and put money in that.
-- Anyone can add answers to a market as long as they stake some amount of M$ on it. Traders can place a bet on any answer and receive shares in the outcome in return.
-- When a user places a bet, their M$ goes into the market's pool and they receive a certain amount of shares of the selected answer.
-- When the market is resolved, you will be paid out according to your shares. If the creator resolves to answer #1, the entire pool is divided up amongst the users who bet on answer #1 proportional to their shares.
-- The creator of each market is responsible for resolving each market. They can resolve to any single answer, or even multiple answers.
-  - Resolving to multiple answers allows the creator to choose a percentage for each selected answer (or distribute equally). The payout for any answer is taken from the amount of the total pool allocated to that answer.
-    - For example, let's take a free-response market with many answers. The pool for this market is $500, and you own 100 out of 500 total shares of answer #1.
-    - If the creator resolves to answer #1 only, you will receive `M$500 * (100 / 500) = M$100`.
-    - If the creator resolves 50% to answer #1 and 50% to answer #2, you will receive `(M$500 * 50%) * (100 / 500) = M$50`.
-    - Note that your payout is dependent on the total number of shares, and thus may decrease if more people buy shares in that answer.
-
-# Fees
-
-- Manifold charges fees on each trade. They are automatically calculated and baked into the number of shares you receive when you place a bet.
-  - Our CPMM fee schedule is currently: `10% * (1 - post-bet probability) * bet amount`
-    - Note that all current binary markets use this fee schedule.
-    - The post-bet probability is what the market probability would be after your bet if there were no fees.
-    - Example:
-      - If you bet M$100 on NO and the resulting probability without fees would be 10%, then you pay `M$100 * 10% * 10% = M$1.0`.
-      - If you bet M$100 on YES and the resulting probability without fees would be 50%, then you pay `M$100 * 10% * 50% = M$5.0`.
-    - 100% of this fee is used to provide a commission to the market creator, which is paid out after the market is resolved.
-  - Our DPM fee schedule is currently: `5% * (1 - post-bet probability) * bet amount`
-    - Note that all free-response markets use this fee schedule. The calculation for this is the same as above.
-    - 4% is used to provide a commission to the market creator, which is paid out after the market is resolved. 1% is "burnt" to prevent inflation.
-  - No fees are levied on sales. If you have existing shares in a binary market and buy shares on the opposite side, that is equivalent to selling your shares and you do not pay fees.
