Top Prediction Market Apps in Florida
In-depth reviews with pros, cons, bonus terms, and direct sign-up links.
Advertising disclosure: MiamiPredictionMarkets is an independent affiliate publisher. We may earn a commission when you sign up for a prediction market platform via links on this page. Compensation never influences our editorial rankings or reviews. Prediction markets involve real financial risk — you must be 21+ and a US resident in an eligible jurisdiction. Read our full disclosure.
These prediction-market platforms — led by Polymarket (#1), OG by Crypto.com (#2) and Kalshi (#3), alongside Rebet, FanDuel Predicts, Robinhood Predictions, and DraftKings Predictions — are the CFTC-regulated event-contract (and licensed sweepstakes) venues fully available to Florida residents 21+ in 2026. Below is the same head-to-head ranking we share with our newsletter, refreshed monthly with real deposits, withdrawals, and live order-book testing from our Miami trading desk — the same desk that prices Heat moneylines, Dolphins win totals, hurricane landfall contracts, and Inter Miami MLS futures for our newsletter every Monday.
