The largest prediction market in the world by volume and market count. Unmatched depth — especially in politics and crypto — but it runs on crypto rails, so you'll need USDC.
Polymarket is the deepest, most liquid prediction market on earth, and the first place to look for anything beyond mainstream US sports — politics, crypto, geopolitics and long-tail world events. After leaving the US in 2022, it returned legally in late 2025 through its acquisition of the CFTC-licensed QCEX exchange, and it’s backed by ICE, the owner of the New York Stock Exchange.
Crypto-comfortable traders who want the widest market selection and the biggest liquidity — and anyone following politics or crypto markets closely.
It settles in USDC on Polygon, so you fund via a crypto wallet (fiat on-ramps feed into USDC). Taker fees are among the lowest in the space, maker orders can earn rebates, and geopolitical/world-events markets are fee-free. Polymarket doesn’t charge deposit or withdrawal fees on your balance.
US access is live in 40+ states but blocked in around eight, and the picture is part of the same fast-moving state litigation as the rest of the sector. Confirm availability in-app and check our legality tracker for your state before funding.
Figures current as of July 2026 and subject to change. Scores reflect our editorial methodology, weighted for US traders. Not financial or betting advice; 18+ (21+ where required).
