Polymarket is the world's largest prediction market by volume, running on blockchain technology and powered by USDC. With billions in total volume and markets on virtually every major world event, it's the platform with the deepest liquidity and widest selection. The blockchain infrastructure means near-instant settlement and full transparency of all positions.
Kalshi is the first CFTC-regulated prediction market exchange in the US, making it the gold standard for compliant, mainstream prediction market trading. It uses regular USD, requires no cryptocurrency, and offers robust economics and policy markets. If you're new to prediction markets or want a regulated environment, Kalshi is the clear starting point.
PredictIt is one of the longest-running prediction markets, focused exclusively on US political events. Its academic partnership model means it operates under a CFTC no-action letter with trade caps per market. Good for political market depth but limited in scope and with higher fees than newer platforms.
