Polymarket

Polymarket enables participants to buy and sell shares that represent the probability of specific outcomes, with prices ranging between zero and one dollar to reflect market expectations. Trades occur in a peer-to-peer order book where users transact directly with one another rather than with a central counterparty. Polymarket uses USDC.e as collateral and represents positions as conditional tokens that are settled through smart contracts on the Polygon blockchain. Event outcomes are resolved through a decentralized oracle process that verifies results before distributing payouts to holders of winning shares. The platform uses a non-custodial model where participants maintain control of their assets through personal wallets while all transactions and positions remain publicly verifiable on-chain.
