Polymarket is a decentralized prediction market built on the Polygon blockchain. Users buy and sell shares representing the outcome of future events — politics, crypto prices, sports, and more. Each share pays $1 if its outcome occurs and $0 otherwise, so the live price reads as the market’s implied probability. Markets resolve through the UMA Optimistic Oracle.
