Prediction markets in Iowa

Contested — injunction denied, on appeal
Kalshi filed a pre-emptive federal suit (March 2026) against the Attorney General and the Iowa Racing and Gaming Commission as the state weighed regulating prediction markets (KalshiEX LLC v. Bird). On September 8, 2026 the court denied Kalshi a preliminary injunction, finding express preemption unlikely and no irreparable harm shown. Kalshi appealed to the Eighth Circuit (No. 26-2874), the first time that circuit has had the question. Nothing bars Iowa from enforcing in the meantime.

The federal-vs-state fight

Every entry in this fight turns on the same question: does a prediction-market platform's federal regulation by the CFTC preempt a state's gambling law, or does the state retain authority to restrict it? Courts around the country are answering that question differently — sometimes for the platform, sometimes for the state — and almost every ruling so far is preliminary and under appeal. Treat this page as a snapshot, not a final word.

This page is informational, not legal advice. Nearly every litigation entry referenced here is a preliminary ruling under appeal. Always verify a platform's current, location-specific eligibility directly with the venue before relying on this page.
