How a Polymarket trade actually works

Pick a market — say, 'Will Bitcoin close above $150K on Dec 31?'. If YES is trading at 38¢, the market is implying a 38% chance. Buy 100 YES shares for $38. If Bitcoin closes above $150K, your shares resolve to $1 each — $100 total, a $62 profit. If it closes below, your shares resolve to $0. You can also sell your position at any time before resolution at the current market price.

Polymarket vs sports betting and stock trading

Polymarket is an event-contract exchange rather than a sportsbook. Contracts are binary (YES or NO, $1 or $0), prices move with supply and demand between users, and a published fee may apply. Each contract has a fixed resolution date and specific settlement rules. They're CFTC-regulated event contracts, not securities.

The platform is available to verified U.S. residents (Polymarket's minimum age is 18; we recommend 21+) in 49 states plus D.C. (not Nevada) through its app.
