Kalshi alternatives
Kalshi alternatives include Polymarket, Polymarket US, ForecastEx (through Interactive Brokers), PredictIt, and the no-money platforms Manifold and Metaculus. Which one fits depends on where you live and whether you want real money at stake.
The short answer for US users: the real-money alternatives that are federally regulated like Kalshi are Polymarket US and ForecastEx, both CFTC-designated exchanges. PredictIt runs under CFTC no-action relief with a per-contract cap. Polymarket's international exchange lists the US as close-only. Builders can also skip choosing: unified libraries like pmxt work across several venues.
