Polymarket
Editor's ChoiceWorld's largest prediction market by trading volume
Polymarket is the largest prediction market in the world by trading volume, with more than $3 billion in cumulative trades on its Polygon-based platform. It is geo-restricted for US users following a 2022 CFTC settlement, so American residents cannot legally access it. Outside the US, it attracts the most active traders globally and offers the deepest liquidity across politics, crypto, sports, and world events. The user experience is clean and modern. The mobile browser experience is excellent. The range of active markets is larger than any other platform we reviewed. If you are outside the US and comfortable with USDC, Polymarket is the gold standard.
