          Similar to Twitch channel point predictions, Manifold Markets allows
          you to create and feature on stream any question you like with users
          predicting to earn play money.
        </div>
        <div>
          The key difference is that Manifold's questions function more like a
          stock market and viewers can buy and sell shares over the course of
          the event and not just at the start. The market will eventually
          resolve to yes or no at which point the winning shareholders will
          receive their profit.
