Prediction Markets in Iowa
Status: contested. Last verified October 2, 2026.
Prediction markets such as Kalshi and Polymarket US are regulated federally by the Commodity Futures Trading Commission. Iowa's Attorney General has questioned whether Kalshi's sports contracts comply with state gambling law. In March 2026 Kalshi sued the Attorney General and the Iowa Racing and Gaming Commission in federal court to block any enforcement. Iowa Capital Dispatch report
On September 9, 2026, Judge Stephen Locher denied Kalshi's request for a preliminary injunction in KalshiEX LLC v. Bird, finding Kalshi unlikely to show that federal law blocks Iowa's gambling laws. Kalshi has appealed to the Eighth Circuit. Court docket, SBC Americas summary
Courts elsewhere are split. The Sixth Circuit ruled for Ohio and Tennessee on September 25, 2026, and the Ninth Circuit ruled for Nevada, while the Third Circuit sided with Kalshi in New Jersey. Sixth Circuit opinion
Iowa lawmakers also considered licensing and taxing prediction markets in 2026. The Senate passed Senate File 2470, but it stalled in a House committee. Iowa Legislature bill page, Gazette report
Prediction markets matter for matched betting because they do not limit winning traders. Check each app for current availability in Iowa before you deposit.

Penalties start at a serious misdemeanor and rise with the amount involved and repeat offences. The statute does not mention online or offshore betting.
