CFTC seeks injunction to freeze Utah criminal case against Kalshi

A federal judge in Utah now has a motion in front of her that the CFTC has never filed before. The Commission is asking the court to halt a state criminal proceeding — not a civil enforcement action, not a licensing dispute, but an active criminal case against two named individuals — on the grounds that federal law gives the CFTC exclusive authority over the contracts at issue. That is a significant procedural ask, and the legal theory behind it is not as settled as either side is currently claiming.

The preemption argument rests on the Commodity Exchange Act and the Supremacy Clause. The CFTC's position, as it has stated publicly, is that event contracts listed on a designated contract market fall under federal jurisdiction and that state criminal law cannot reach conduct the agency has already authorized. CFTC Chair Michael Selig has framed this as a jurisdiction claim, and technically that is correct. What that framing obscures is how narrow the doctrine of field preemption actually runs in the criminal context.

Courts have generally been reluctant to enjoin state criminal proceedings. The threshold for such an injunction — absent a finding that the prosecution is in bad faith or that it constitutes harassment — is high enough that federal agencies rarely attempt it. The CFTC is attempting it. That tells you something about how the Commission reads its own litigation position on the civil preemption suits already working through the Fifth Circuit and elsewhere: not as strong enough to wait.

The consensus read in the coverage I have seen treats this as a straightforward extension of the preemption war. I think that undersells the risk the CFTC is taking. If the federal judge denies the injunction — and there are serious doctrinal reasons she might — Utah's criminal case proceeds, and the CFTC will have litigated itself into a posture where a federal court has implicitly declined to recognize the scope of its own preemption claim. That result would land in every state attorney general's brief that is currently being drafted.

Section 1256 of the tax code is a separate thread worth holding. That provision gives favorable tax treatment to regulated futures contracts. It was written for futures. It does not name event contracts, and neither the IRS nor Congress has amended it to address prediction market instruments. Whether Kalshi's contracts qualify for Section 1256 treatment is an open question that becomes considerably more complicated if a federal court rules that those contracts occupy ambiguous regulatory territory. The Commission cannot simultaneously argue that these are fully regulated futures for preemption purposes and remain silent on whether they are futures for tax purposes. At some point, those two positions meet.

The standard a court applies when deciding whether to enjoin a state criminal proceeding is whether the plaintiff can demonstrate a clear right to relief and that the prosecution constitutes an attempt to enforce a law that federal authority has expressly preempted. The CFTC's motion stands or falls on whether it can meet that showing on the existing record — before any appellate court has ruled on the preemption question in this specific contract class.
