Polymarket is a decentralized prediction market platform built on the Polygon blockchain where users buy and sell outcome shares for real-world events. Each market resolves to either $1 (if the event happens) or $0 (if it does not). The current trading price of a share reflects the crowd's estimated probability of that outcome occurring, making Polymarket a real-time aggregator of collective intelligence on politics, economics, technology, and culture.
A Polymarket market poses a yes/no question (for example, "Will the Fed cut rates before July 2026?"). Users deposit USDC and buy Yes or No shares. If you buy a Yes share at $0.65, you are paying 65 cents for a contract that pays $1 if the event happens. If you are right, you profit $0.35 per share. If wrong, you lose your $0.65. Shares can be traded at any time before resolution, creating a dynamic price that moves as new information emerges.
Markets are resolved by an oracle system that determines the outcome based on predefined criteria. Polymarket uses UMA's optimistic oracle, where outcomes are proposed and can be disputed within a challenge period. This decentralized resolution mechanism removes the need to trust a single entity to determine results.
Prediction markets have consistently outperformed polls, pundits, and expert panels at forecasting binary events. They work because participants have financial skin in the game, which incentivizes accurate assessment over wishful thinking or partisan bias. Polymarket's open, liquid markets provide real-time probability estimates for events that traditional forecasting handles poorly, from election outcomes to tech product launches to regulatory decisions.
The Prediction Markets panel on the TerminalFeed dashboard pulls live market data from Polymarket via the Gamma API, showing current odds on trending events. The Prediction Markets article on the blog explores how odds translate to real-world probabilities and why prediction markets matter for traders and analysts.
