Prediction Market Laws. (2026, October 28). KalshiEX LLC v. Hanaway. https://predictionmarketlaws.com/lawsuits/kalshi-v-hanaway-edmo
Complaint filed Oct. 27, 2026. Kalshi has said it will seek a preliminary injunction; no ruling as of Oct. 28, 2026.
The question
Whether federal commodities law preempts Missouri's gambling laws as applied to Kalshi's sports event contracts.
After the attorney general's office told Kalshi to pull its sports contracts from Missouri, Kalshi sued in federal court with a single Supremacy Clause claim, seeking declaratory and injunctive relief against enforcement.
Docket timeline
Kalshi files suit against the attorney general and Gaming Commission.
