State pressure on sports event contracts moved on two fronts this week. Polymarket US took Ohio to federal court over its licensing rules, while Utah sued Kalshi in its own name. Meanwhile the CFTC's proposal to classify event contracts as swaps is now out for comment, setting up the federal-state preemption question for the rulemaking record.

Polymarket US sues Ohio officials over sports betting licensing rules
QCX LLC, operating as Polymarket US, sued the Ohio Attorney General and Ohio Casino Control Commission officials in the Southern District of Ohio (Case No. 2:26-cv-01502) on October 16, seeking preliminary and permanent injunctions. The complaint argues Ohio's in-state presence and server requirements discriminate against interstate commerce and that Ohio gambling law is preempted by the Commodity Exchange Act. It follows the Commission's October 2 cease-and-desist letters, so compliance and litigation teams should track the preliminary injunction schedule.

Utah sues Kalshi in state court, alleging illegal gambling and public nuisance
Utah Attorney General Derek Brown filed suit on October 20 alleging Kalshi's event contracts are indistinguishable from sportsbook bets under Utah's constitutional gambling prohibition. The state seeks an order to cease operations in Utah, disgorgement, restitution and geolocation blocking, and estimates Kalshi's Utah profits at $30.6 million to $61.2 million. A state-initiated enforcement action, as opposed to an operator-initiated preemption suit, adds a distinct litigation track for operators to monitor.

CFTC proposes to include event contracts in the definition of swap
In Release No. 9310-26 (October 9), the CFTC issued a Notice of Proposed Rulemaking that would add event contracts, including sports, politics, culture and weather contracts, to the regulatory definition of swap. Chairman Michael S. Selig described the products as commodity derivatives within the CFTC's remit under the Commodity Exchange Act. Comments are due 30 days after Federal Register publication, so firms should confirm the deadline in the Federal Register and plan submissions accordingly.

Ohio regulator warns gaming licensees to cut ties with prediction market operators
Per Sports Betting Dime, an October 20 notice from the Ohio Casino Control Commission tells licensees and applicants that supporting operators offering sports event contracts without an Ohio sports gaming license may affect their own licenses, with an October 30 deadline. The notice cites liquidity provision, market making, integrity monitoring and technology services. Vendors and market makers serving both licensed and prediction-market clients should review Ohio exposure now.
