New to prediction markets?

A price here is a probability: 62¢ means the market puts the outcome at roughly 62%. The guide to paper trading these markets walks through reading one, taking a side and checking the result. If you came from a real book, there is a shorter version on practising with Polymarket’s odds, and a comparison of the free prediction market simulators if you are still choosing one.

Everything below trades with simulated money. When you want a scoreboard, run a game against your own group over the same questions, or browse the full market directory.
