How Polymarket prediction markets work

Understand Yes/No shares, resolution sources, order books and USDC settlement.

Choose an event contract and read the resolution criteria before trading.

Pay USDC for shares. A 65¢ Yes price implies ~65% implied probability.

Sell before resolution or hold until the event outcome settles the contract.

Winning shares redeem at $1 each after official resolution.

Is Polymarket a casino?

No. Polymarket lists event contracts — binary Yes/No shares on real-world outcomes — not slot machines or house-banked casino games.

How are odds shown?

Contract prices in cents map to implied probability. 70¢ Yes ≈ 70% chance priced by traders.

What currency is used?

Trading uses USDC on supported chains. Fund your wallet after verifying regional eligibility.
