Kalshi has filed suit against the Ohio Casino Control Commission in the U.S. District Court for the Southern District of Ohio to block a proposed $5 million civil penalty arising from OCCC Executive Director Matthew Schuler’s finding that the platform operated as an unlicensed sportsbook in violation of Ohio gaming law – with Kalshi contending that its status as a CFTC-registered designated contract market renders the state’s enforcement action preempted under the Commodity Exchange Act.
The OCCC’s penalty notice alleges that Kalshi accepted wagers from persons under 21, failed to remit Ohio’s 20% sports gaming tax, and violated state advertising requirements – framing the platform’s sports-event contracts not as federally regulated derivatives but as sports betting conducted without a state licence. Kalshi has 30 days from the commission’s notice to request a hearing and contest the assessment, a procedural window it has now attempted to short-circuit through federal court. The suit seeks injunctive and declaratory relief, with Kalshi arguing that forcing it to geo-block Ohio users and construct untested technological workarounds causes immediate and irreparable harm to its operations as a federally approved exchange.
The district court proceedings run parallel to – and are substantially shaped by – Kalshi v. Ohio Casino Control Commission, the appellate case in which the U.S. Court of Appeals for the Sixth Circuit has scheduled oral argument for July 30. Chief Judge Sarah D. Morrison denied Kalshi’s motion for a preliminary injunction in March 2026, holding that Kalshi had not demonstrated its sports contracts qualify as CEA-regulated swaps and declining to find that federal law displaces Ohio’s authority to treat them as gambling. The Sixth Circuit declined emergency relief on April 24, describing the legal questions as close but finding Kalshi had not met the standard for a stay pending appeal.
Morrison’s opinion went directly to the core of Kalshi’s legal theory, finding nothing in the CEA’s text or legislative history suggesting Congress intended to classify sports event contracts as swaps – a determination that, if affirmed at the Sixth Circuit, would leave Ohio’s enforcement posture fully intact through the merits phase. Legal commentators in Ohio have characterised the district court’s reasoning as a straightforward application of the principle that sports betting by another name remains sports betting, a framing that the OCCC has consistently advanced in its correspondence with licensed operators whom it warned against partnering with Kalshi earlier in the dispute.
Ohio sits within a contested multi-state landscape in which Kalshi has obtained injunctions in California, New Jersey, and Tennessee but has been rebuffed in Maryland, Massachusetts, Nevada, and now Ohio at the preliminary injunction stage. Nevada’s proceedings have moved further still – Nevada has pursued contempt orders against Kalshi over geofencing compliance failures – illustrating that the enforcement tools available to states extend well beyond the initial cease-and-desist stage. The CFTC has responded to this multi-state pressure with an affirmative preemption campaign that has now reached nine states; the broader jurisdictional conflict is directly at issue in the CFTC’s federal litigation against Kentucky, where the agency is seeking to block application of state gambling laws and a new excise tax to prediction market contracts.
A 40-state attorney general amicus coalition has aligned against the CFTC’s preemption theory, and Kentucky’s AG has filed its own suit against Kalshi alleging illegal gambling – a posture that mirrors Ohio’s and that will bear directly on how courts in the Sixth Circuit evaluate the competing jurisdictional claims. Business Insider has reported Kalshi’s public position as disappointment with the Ohio rulings combined with continued reliance on favourable decisions in other states to support its claim of a federal right to operate. The July 30 Sixth Circuit oral argument in Kalshi v. Ohio Casino Control Commission represents the nearest inflection point for the penalty proceedings, with the appellate outcome potentially reframing the district court’s preemption analysis before the civil fine reaches final adjudication.
The open question enforcement observers are now tracking is whether the Sixth Circuit’s July 30 ruling arrives in time to reshape the district court’s analysis of the $5 million civil penalty – and whether a finding that Ohio’s prohibition is preempted by the CEA necessarily carries through to the penalty mechanism itself, or whether Ohio can sustain the fine on independent state-law grounds even if the broader enforcement posture is ultimately displaced by federal authority.
