PredictionMarketApps compares the apps Americans use to trade on the outcome of real events: elections, games, interest rate decisions, the weather. Kalshi, Polymarket, Robinhood and Crypto.com are the four we cover in depth so far, and we’re adding more.
These apps change fast. Fees get rewritten, states block sports contracts, and offers come and go within weeks. So every review shows the date we last checked its facts against the app’s own pages, and we’d rather tell you two of the app’s pages disagree than guess which one is right.
We’re independent. None of the apps pay us, and you can see how every score is worked out on how we rate apps. If you spot something out of date, please tell us.
