Montana federal court denies Kalshi injunction as state enforcement holds
In a Helena courtroom, a federal judge declined to halt Montana's enforcement action against Kalshi, refusing the company's motion for a preliminary injunction and leaving state regulators free to proceed while the underlying case is resolved on the merits.
The ruling in Montana arrived alongside the Ninth Circuit's determination that Kalshi's sports event contracts do not qualify as CFTC-regulated swaps — a classification that had been the load-bearing wall of Kalshi's federal preemption argument. If the contracts are not swaps under the Commodity Exchange Act, the preemption claim built on swap regulation does not reach them. That is not a procedural setback. It is a structural one.
Kalshi's position across its state litigation has rested on a single federal theory: that CFTC designation as a designated contract market places its contracts beyond the reach of state gaming and licensing law. The Ninth Circuit's swap classification ruling does not eliminate that theory entirely, but it removes one of its cleaner statutory anchors. The argument now has to work harder to explain why the Commodity Exchange Act's preemptive force extends to contracts the Ninth Circuit has just said fall outside the Act's swap framework.
The preliminary injunction standard requires a movant to show likelihood of success on the merits, irreparable harm, balance of equities, and public interest. The Montana court's denial means the judge found Kalshi had not cleared that bar — most likely on the merits prong, given how recently the Ninth Circuit spoke. A court asked to freeze state enforcement based on a federal preemption theory has less reason to do so the week after an appellate panel rejected a central piece of that theory in the same circuit.
What I keep coming back to is how the injunction calculus changes once a circuit rules against you on the underlying legal architecture. I have watched preemption arguments that looked strong in district court lose their traction the moment an appellate decision gave the lower courts permission to be skeptical. The Montana denial reads like exactly that.
The Supreme Court's involvement, reported separately, may ultimately resolve the circuit questions. But that resolution, if it comes, comes later. In the interval, state enforcement proceeds. Montana proceeds. Connecticut has its own action pending. The daily fines in Nevada remain in place. Each week the preliminary injunction strategy fails is a week state regulators build a factual record that a reviewing court will eventually have to confront.
Under the Commodity Exchange Act, the CFTC can designate certain contracts as swaps subject to federal regulation, which may preempt state gaming and licensing restrictions. Kalshi argued that its CFTC designation as a designated contract market placed its sports event contracts beyond reach of state enforcement. However, the Ninth Circuit determined Kalshi's contracts do not qualify as swaps under the Act, removing the statutory anchor for that preemption claim.
The Ninth Circuit determined that Kalshi's sports event contracts fall outside the Commodity Exchange Act's swap framework. The article does not specify the Court's detailed reasoning, but this classification directly undermined Kalshi's core legal theory that federal swap regulation preempted Montana's state enforcement action against the company.
Montana's federal court refused Kalshi's motion for a preliminary injunction, allowing state regulators to proceed with enforcement while the underlying case is resolved on the merits. Connecticut has its own action pending, and Nevada's daily fines against Kalshi remain in place. Each week state enforcement continues, regulators build a factual record that reviewing courts must eventually confront.
A preliminary injunction requires showing likelihood of success on the merits, irreparable harm, balance of equities, and public interest. Victoria Blackwell of Gambity notes that courts are less likely to freeze state enforcement based on federal preemption theory immediately after an appellate panel rejected a central piece of that theory in the same circuit, making Kalshi's injunction strategy considerably harder to execute.
