Polymarket

Polymarket is a decentralized prediction market platform where users trade binary outcome contracts on real-world events. Launched in 2020 by founder Shayne Coplan and based in New York City, the platform operates on the Polygon blockchain, using USDC stablecoin for all transactions. Users buy and sell shares priced between $0.01 and $0.99, reflecting market-implied probabilities; winning shares pay $1 USDC upon event resolution, while losing shares expire worthless. The peer-to-peer structure eliminates house edge, with transparent on-chain pricing and near-instant settlement.

Markets span politics, sports, crypto, finance, culture, weather, technology, and world affairs. The platform gained explosive growth during the 2024 U.S. presidential election cycle and 2026 midterms, with its prices frequently cited by media as alternative polling data. In 2025, Polymarket became the Official Prediction Market Partner of X (formerly Twitter) and Stocktwits, and received a strategic investment from Intercontinental Exchange (ICE). The platform also acquired QCEX (via QCX LLC, d/b/a Polymarket US) to provide CFTC-regulated infrastructure, earning contract market designation in July 2025 and a no-action letter for event-contract reporting in September 2025.

Polymarket has faced regulatory scrutiny, settling with the CFTC in 2022 for $1.4 million over operating an unregistered binary options platform. It now operates with full compliance, requiring KYC verification for all users. The platform commands over 70% of decentralized prediction market volume, far exceeding competitors like Augur, Gnosis, and Polkamarkets. Critics point to risks of market manipulation, insider trading, and concentration of profits among a small fraction of accounts. Nonetheless, Polymarket has become a real-time barometer of public sentiment, sparking debate about the ethics of betting on sensitive subjects like wars and military actions. [edit]
