Prediction Markets Legal in the US: What You Need to Know

The United States has one of the most regulated prediction market environments in the world. Most global platforms — including Polymarket, the world's largest prediction market by volume — explicitly block US users. This isn't arbitrary: US commodity law requires that any platform offering financial contracts on real-world events obtain CFTC (Commodity Futures Trading Commission) approval, a process most offshore platforms haven't pursued.

The result is a smaller but legally safe set of options for US traders. Kalshi is the gold standard: the only platform with full CFTC designation as a registered contract market (DCM), the same regulatory category as the CME Group. Robinhood Predictions is a newer CFTC-regulated entrant with zero trading fees. PredictIt operates under a CFTC no-action letter — a more limited authorization focused on political markets.

The key distinction for US traders is between full CFTC regulation (Kalshi, Robinhood) and no-action letter authorization (PredictIt, Iowa Electronic Markets). Fully regulated platforms offer stronger legal protections, clearer fund segregation, and broader market categories. No-action letter platforms are still legal but operate in a narrower regulatory space.

If you're in the US and want to participate in prediction markets legally, Kalshi is currently the safest and most feature-complete option. If fees are your primary concern, Robinhood Predictions offers 0% fees and $1 minimums for existing Robinhood account holders.
