What is Polymarket?

Polymarket is the dominant decentralized prediction market platform, running on Polygon and processing hundreds of millions of dollars in trading volume during major events like US presidential elections, Fed rate decisions, and crypto regulatory outcomes. Unlike polls and surveys, Polymarket markets aggregate the collective beliefs of financially incentivized participants — people putting real money on outcomes they believe will happen — producing probability estimates that consistently outperform traditional polling and expert forecasts. The platform uses a CLOB (Central Limit Order Book) model powered by the UMA optimistic oracle and Polymarket's own CLOB system for fast and accurate resolution. Markets are denominated in USDC; US persons are geo-blocked under current regulatory conditions. For analysts and researchers, Polymarket odds have become a standard reference for real-world probability assessment — cited by mainstream media, academics, and policy researchers during elections and major geopolitical events. The API provides real-time and historical market odds data, enabling integration into news aggregators, trading dashboards, and research tools. Polymarket does not require an account for reading odds — you can embed live probability data from any market into your own application. Market creation is permissioned but traders can request new markets through governance.
