ポリマーケット

Polymarket is an on-chain prediction market platform that enables users to trade on the outcomes of future events across politics, sports, finance, technology, and global affairs. Participants buy and sell outcome shares priced between $0 and $1, reflecting the market’s real-time consensus probability of an event occurring. Markets are peer-to-peer and allow users to exit positions before resolution, enabling profit-taking or risk management without relying on a traditional bookmaker.

All markets are fully collateralized using USDC on the Polygon network, ensuring that shares corresponding to the correct outcome settle at $1 upon resolution. Prices dynamically adjust based on supply and demand, producing transparent, continuously updated odds that reflect aggregated market sentiment. This mechanism allows prediction markets to surface collective intelligence, which research has shown can outperform traditional polls and expert forecasts.

Polymarket operates as a non-custodial, on-chain platform with centrally curated markets and oracle-based resolution, combining decentralized settlement with a streamlined user experience. Developers and analysts can access public APIs and data feeds to track market activity, probabilities, and liquidity for analytics or integrations. With real-time insights and a broad range of markets, Polymarket serves as a forecasting tool that blends decentralized finance mechanics with real-world information discovery.
