Kalshi's Utah Loss Is the First Final Word Against Preemption

On August 4, 2026, U.S. District Judge Robert Shelby granted summary judgment to the State of Utah in Kalshi v. Utah, rejecting every preemption theory Kalshi raised against the state's expanded anti-gambling law, HB 243. Shelby wrote that Kalshi had not met its burden of showing that state and federal regulation of its sports-event contracts cannot coexist, stating plainly that enforcement of state gambling laws is not inconsistent with the CFTC's own regulation of the same products.

Kalshi filed the underlying suit in February 2026, seeking to block Utah from applying its gambling statute to its federally listed sports contracts. The court closed the case with its ruling, and Kalshi filed a notice of appeal to the Tenth Circuit on August 5, one day later.

Kalshi has lost preemption arguments before, including preliminary-injunction denials in Maryland, Ohio, and Wisconsin, and a merits-stage preliminary injunction against it in Washington state court. Each of those, by definition, left the underlying legal question open pending further proceedings.

The Utah ruling is different because it is final. Judge Shelby granted summary judgment and closed the case outright, making it, by multiple outlets' accounts, the first non-preliminary federal judgment anywhere in the country to reject Kalshi's core preemption theory rather than merely decline to block enforcement while litigation continues.

Judge Shelby's opinion notably did not resolve whether Kalshi's sports contracts qualify as CEA 'swaps,' the threshold question at the center of the Third Circuit's pro-Kalshi ruling in the New Jersey case and the Sixth and Ninth Circuit appeals still pending. Instead, the court found multiple plausible readings of the CEA's jurisdictional provisions and applied a general presumption against preemption when statutory text is ambiguous.

The court also rejected Kalshi's argument that complying with Utah law would conflict with the CFTC's impartial-access requirements for DCMs, reasoning that those requirements are aimed at preventing discrimination based on a trader's financial resources, not at preventing a state from restricting access on gambling-law grounds tied to geography.

Utah's win pushes prediction-market preemption litigation into a seventh federal circuit, joining the Third (favoring Kalshi in New Jersey), Fourth, Sixth, and Ninth Circuits, where appeals remain pending, and the Sixth Circuit specifically, which heard consolidated Ohio and Tennessee oral arguments on July 30, 2026 without yet ruling. Two Michigan federal judges have already ruled against Kalshi and Polymarket on the underlying swap-definition question, directly conflicting with the Third Circuit's holding.

A separate August 6 ruling out of the Eastern District of Michigan, denying Coinbase Financial Markets a preliminary injunction against Michigan's enforcement of its own sports-betting law, reinforced the same skepticism, with the judge reportedly dismissing the preemption argument as unconvincing. Taken together, the pattern suggests district courts are increasingly comfortable ruling on the merits against preemption, not just declining to grant emergency relief.

Kalshi's Tenth Circuit appeal will test whether an appellate court is willing to follow the Third Circuit's reasoning that sports-event contracts are CEA swaps entitled to field and conflict preemption, or the more skeptical approach taken by the Michigan and Utah district courts. With the Sixth Circuit's consolidated Ohio and Tennessee ruling still pending and now a Tenth Circuit appeal added to the docket, the operative legal question, whether sports-event contracts are swaps under the Commodity Exchange Act at all, is on track to reach the Supreme Court through one of several possible paths, including New Jersey's pending certiorari petition.

For operators, the practical takeaway is that a federal DCM designation does not currently guarantee immunity from state gambling enforcement in every jurisdiction, and the outcome may continue to vary by circuit until a definitive appellate or Supreme Court ruling settles the swap-definition question nationwide.
