Prediction Market Laws. (2026, October 28). QCX LLC v. Murrill. https://predictionmarketlaws.com/lawsuits/polymarket-v-murrill-edla
Complaint filed Oct. 27, 2026; no ruling as of Oct. 28, 2026.
The question
Whether the Commodity Exchange Act preempts Louisiana's threatened enforcement against Polymarket US, and whether that enforcement violates the Commerce Clause.
Polymarket US's exchange sued Louisiana's attorney general and Gaming Control Board members, citing the board's Dec. 5, 2025 advisory notice calling sports event contracts illegal gambling. It argues federal preemption and a Commerce Clause violation.
