# CFTC Challenges Arkansas Event-Contract Restrictions

On November 13, 2026, the Commodity Futures Trading Commission (CFTC) sued Arkansas, arguing that federal law preempts the state’s efforts to halt event-contract trading and impose civil penalties on CFTC-registered exchanges. The suit follows Arkansas’s civil enforcement action against Kalshi, and the CFTC has brought similar cases against 10 other states. The litigation could affect how prediction-market operators and their service providers assess federal oversight and state-level enforcement; the signals identify no procurement opportunity, contract award, or solicitation.

- Exchanges and related service providers should assess how differing state enforcement positions affect their compliance planning and business operations.
- Government contractors and firms supporting these platforms may need to account for the unresolved federal-versus-state jurisdiction dispute when defining regulatory, legal, or operational support services.
