How We Evaluated These Platforms

We evaluated each platform across six dimensions that matter most to traders: regulatory status (legal certainty), market coverage (breadth and depth of available markets), liquidity (ability to enter and exit positions efficiently), fees (total cost of trading), API access (programmability for quants and developers), and user experience (ease of onboarding and daily use).

The prediction market landscape has changed dramatically since 2023. Kalshi won its CFTC court battle to list election contracts, Polymarket processed billions in election volume, and sportsbooks like DraftKings entered the event betting space. Understanding the strengths and tradeoffs of each platform is essential for finding the best trading venue for your specific strategy.
