Polymarket is the largest crypto-based prediction market, letting users trade on the outcomes of real-world events using USDC on Polygon, with resolution via the UMA optimistic oracle. Note: it has faced US regulatory action (a CFTC settlement) and restricts US users — availability and legality vary by jurisdiction.
