Getting Funded
Sign up with email or wallet, then deposit USDC on Polygon — direct from an exchange (cheapest: withdraw USDC to your Polymarket address on the Polygon network), by bridging from other chains, or by card through onramp partners (higher fees). The interface abstracts most crypto friction; balances display as plain dollars.
Trading the Markets
Each market's Yes/No shares trade on an order book between 0¢ and $1.00. Market orders fill instantly at the best price; limit orders rest until matched — on thinner markets, always use limits, because wide spreads are where casual users quietly lose. Positions can be sold anytime; the graph shows the live probability history. Fees are effectively embedded in spreads rather than charged per trade.
Resolution and Withdrawal
Markets resolve per their stated rules — read them before trading, since edge cases ('by what date', 'per which source') decide disputed markets. Resolution runs through UMA's optimistic oracle: proposed outcomes stand unless disputed and voted. Winning shares redeem at $1.00; withdrawals send USDC back on-chain in minutes. US access: Polymarket returned to the US market under CFTC oversight via its regulated exchange acquisition — check current terms for your state.
