FAQ — Polymarket
Can non-US users use Polymarket? +
Yes: Polymarket is freely available to users outside the United States, including those in the UK, via a crypto wallet. US retail users are restricted on the main platform following a 2022 CFTC settlement, though a licenced US app is rolling out via waitlist. Non-US users need a compatible wallet (MetaMask, Phantom, or Coinbase Wallet) funded with USDC.
Do I need a crypto wallet to use Polymarket? +
Yes. Polymarket settles all trades in USDC on the Polygon blockchain. You need a compatible crypto wallet, such as MetaMask, Coinbase Wallet, or Phantom, funded with USDC to trade. There is no fiat (bank) on-ramp directly on the platform.
What fees does Polymarket charge? +
Polymarket charges approximately 2% on taker orders (market buys and sells). Limit orders that rest in the order book are charged a lower or zero maker fee. Fees are taken in USDC at the time of the transaction. Polygon gas fees are negligible, under $0.01 per transaction.
Is Polymarket safe? +
Polymarket uses on-chain settlement via UMA's optimistic oracle on Polygon: funds are held in audited smart contracts rather than with a centralised custodian, which removes counterparty risk but introduces smart-contract risk. The platform has processed over $8 billion in lifetime volume without a systemic failure.
What markets are on Polymarket? +
Polymarket focuses on global politics (elections, geopolitics, international affairs), economics, science, and culture. It does not offer sports markets. Its order books are the deepest in the world on major political events, US and international elections, geopolitical developments, and economic outcomes.
