The Commodity Futures Trading Commission has filed suit against Kentucky in the U.S. District Court for the Eastern District of Kentucky, seeking to block the state from applying its gambling laws and a newly enacted excise tax to sports-event contracts traded on CFTC-registered designated contract markets – marking Kentucky the ninth state targeted by the agency in its coordinated CEA preemption campaign, which launched on April 2, 2026. The complaint names Governor Andrew Beshear, Attorney General Russell Coleman, and the Kentucky Horse Racing and Gaming Corporation as defendants, and seeks both a declaratory judgment and a permanent injunction against enforcement of Kentucky’s gambling statutes and tax provisions as applied to DCM-listed event contracts.
Kentucky’s position in this litigation is structurally distinct from any prior defendant state: it is simultaneously a plaintiff – through Coleman’s own state-court suits against prediction-market operators – and now a defendant against the federal regulator those operators sit under. Coleman filed suit against KalshiEx LLC and Polymarket in state court, alleging both platforms were conducting illegal sports wagering in Kentucky, an action that helped trigger the CFTC’s federal response. The jurisdictional complexity intensified further when Kentucky’s General Assembly adopted House Bill 757 in April 2026, creating a 14.25% excise tax applied to transaction fees and the notional value of event contracts traded in Kentucky or by Kentucky residents – a levy the CFTC’s complaint characterises as a mechanism designed to pressure federally registered exchanges out of the state rather than a neutral revenue measure.
The CFTC’s legal theory tracks the position it has advanced in each of the prior eight state suits: sports-event contracts are swaps under the Commodity Exchange Act, DCMs have exclusive federal oversight over those instruments, and state gambling prohibitions or penalty regimes that purport to reach CEA-regulated activity are preempted as a matter of federal supremacy. CFTC Chair Michael Selig said Kentucky is “the latest state trying to shut down federally-regulated event contracts,” while Coleman has argued the platforms are operating “illegal sportsbooks” in the state. Coleman’s framing mirrors the position advanced by the 41-attorney-general coalition that has filed amicus briefs opposing the CFTC’s preemption theory in multiple appellate proceedings, including a 40-state brief in the Sixth Circuit in Kalshi v. Ohio Casino Control Commission, where oral arguments are scheduled for July 30 – a date that now gives the Kentucky proceedings an immediate appellate backdrop against which the Eastern District will have to situate its own analysis.
The Third Circuit’s ruling in KalshiEX LLC v. Flaherty remains the strongest appellate precedent supporting the CFTC’s posture, having declined to disturb a DCM’s right to list sports-event contracts under federal oversight. The CFTC has filed amicus briefs in the Sixth and Ninth Circuits and the Massachusetts high court to extend that logic across jurisdictions, and has paired those filings with the affirmative state-suit campaign to avoid being in the position of defending operators only in cases brought against the companies themselves. The dual-relief structure – declaratory judgment plus permanent injunction – has been consistent across all nine state complaints, as has the CFTC’s decision in some prior suits to bring the Department of Justice as co-plaintiff; whether DOJ joins the Kentucky action has not been confirmed in filings reviewed at the time of publication.
The Kentucky suit lands inside a multi-front campaign that has now reached at least nine states targeted by the CFTC, with Chair Selig having referenced nearly 50 active legal matters tied to the prediction-market preemption effort. According to Front Office Sports, the agency’s pattern has been to file affirmative suits against states after those states move against prediction-market operators, rather than waiting to defend platform licensees in proceedings the states control. Kentucky is the first state in the campaign with a Republican attorney general, a detail CNBC noted as politically significant given that opposition to the CFTC’s jurisdictional claims has otherwise skewed along lines shaped more by state sovereignty arguments than partisan alignment. The broader state coalition opposing CFTC jurisdiction has framed the preemption campaign as a federal overreach into traditional state police power over gambling – an argument that the Kentucky proceedings, with their overlapping state-plaintiff and federal-defendant postures, will test from an unusually complicated procedural angle.
The open question enforcement observers are now tracking is whether the simultaneous posture – Coleman prosecuting operators in Kentucky state court while the CFTC prosecutes Kentucky in federal court – produces conflicting rulings on the same underlying question of CEA preemption, and whether the Sixth Circuit’s July 30 oral argument in Kalshi v. Ohio Casino Control Commission delivers guidance that reshapes the Eastern District of Kentucky’s analysis before the Kentucky case reaches a merits ruling on the 14.25% tax.

She came up through the compliance side of the industry before pivoting to writing, which gives her a grounded, no-nonsense perspective on the rules, loopholes, and political maneuvering that shape how operators actually do business. She is particularly drawn to the gap between what regulators say and what the market ends up doing in response.
