Federal courts in Ohio to rule on prediction market authority

Ohio's federal courts become the next arena for prediction market preemption

QCX LLC filed its complaint in Ohio's Southern District on October 16. The defendant list runs to nine names: Attorney General Andy Wilson, Interim Executive Director Andromeda Morrison, and seven Ohio Casino Control Commission members. Judge Douglas R. Cole has the case.

The filing came fourteen days after the OCCC sent cease-and-desist letters to Polymarket and nine other operators, classifying sports event contracts as sports gaming and giving recipients until a stated deadline to comply. Most kept their contracts live. Plus500US did not. Polymarket did not. Robinhood did not. That division — between operators who folded and operators who held — is the more important fact here, because it shapes what the federal court actually has to decide.

Polymarket's argument has two components. The first is constitutional: Ohio's Type A licensing framework requires an in-state business presence and caps proprietor licenses at twenty-five, with regulators weighing local economic contribution when evaluating applicants. Add the requirement that wagering servers sit on Ohio soil, and add the restriction that customers must be physically within the state, and you have what the complaint calls "discriminatory, balkanizing measures." The dormant commerce clause argument is well-established law. Courts apply it routinely. On this component alone, Polymarket's position is stronger than the reporting has suggested.

The second component is federal preemption under the Commodity Exchange Act, and this is where the structure gets complicated. The Sixth Circuit ruled unanimously in September that Kalshi's sports contracts were not swaps under the CEA, and that federal law would not override Ohio and Tennessee's gambling statutes even if they were. Polymarket acknowledges the ruling and argues it predates the CFTC's October 9 interim final rule, which took effect October 19 and excludes state-licensed sportsbook wagers and casino games from the swap definition. Comments on the proposal are due November 18.

The CFTC's rule does not reverse the Sixth Circuit. What it does is complicate the preemption question in ways the appeals court did not have before it. Whether that complication is enough to move Judge Cole is genuinely open. The Sixth Circuit's ruling was about the nature of the contracts. The CFTC's subsequent action is about the scope of the exemption. They are addressing adjacent questions, not the same one.

The consensus read is that the Sixth Circuit ruling has effectively closed the preemption door. Having spent time in a previous position watching agencies and courts talk past each other on exactly this kind of jurisdictional seam, the more durable observation is that administrative action taken after an appellate ruling creates a new record, and new records sometimes produce new results. Not always. But the door is not as closed as the Sixth Circuit outcome alone implies.

The dormant commerce clause claim is the one I would watch in this district. Ohio's server requirement and its physical-presence licensing conditions are structurally weaker under interstate commerce doctrine than the preemption argument is under CEA case law. If Polymarket gets a preliminary injunction, it is more likely to arrive on that ground than on the federal override question.
