Yes! Manifold is very well calibrated, with forecasts on average within 4 percentage points of the true probability. Our probabilities are created by users buying and selling shares of a market.

In the 2022 US midterm elections, we outperformed all other prediction market platforms and were in line with FiveThirtyEight’s performance. Many people who don't like trading still use Manifold to get reliable news.

Manifold offers two market types: play money and sweepstakes.

All questions include a play money market which uses mana and can't be cashed out.

Selected markets will have a sweepstakes toggle. These require sweepcash  to participate and winners can withdraw sweepcash as a cash prize. You can filter for sweepstakes markets on the browse page.
