The fee problem
PredictIt keeps 10% of your winnings on each trade and another 5% of anything you withdraw. Combined, a strategy needs roughly a 12% edge just to break even — which is why PredictIt prices often diverge from Polymarket and Kalshi on identical events. Treat those divergences as a fee artifact, not free money: the cost of arbitraging them away is exactly what created them.
Position caps
The $850-per-contract-per-question cap, a condition of its original academic no-action letter, keeps stakes small. It democratizes the market but also caps the incentive for sharp money to correct prices, so long-shot bias is more visible here than anywhere else.
Community and longevity
What PredictIt does have is history and people. It has operated through multiple election cycles, survived a CFTC withdrawal attempt that was resolved in court, and maintains comment sections that are arguably the best free source of granular US political handicapping anywhere.
Our verdict
PredictIt survives on community and nostalgia more than economics. The 10%-plus-5% fee stack and $850 cap make it hard to recommend for profit-focused traders, but its political markets and comment threads remain genuinely fun.
Best for: Political junkies who value the community over raw economics
