CFTC preemption claim meets its hardest test in Utah state court

Kalshi's federal preemption argument has been tested in New Jersey, challenged in Ohio, and examined in Missouri. Utah is different, and the difference is not the dollar amount.

The Utah Constitution has prohibited gambling since statehood. Not since a legislature voted on it, not since a regulatory agency drew a line — since 1896, as a condition of joining the union. Attorney General Derek Brown's lawsuit, filed October 20 in the Third District Court, rests on that foundation. When Kalshi's spokesperson Jacki McGavick responded that "no single state should have a veto," she was describing the federal preemption doctrine accurately. She was also describing what the next eighteen months of litigation will actually decide.

The Supremacy Clause establishes that federal law governs when it conflicts with state law. The operative question in this case is whether the Commodity Exchange Act, which gives the CFTC jurisdiction over designated contract markets, actually conflicts with Utah's constitutional prohibition — or whether the two can coexist, with federal law regulating the exchange and state law prohibiting residents from participating in it. Courts have allowed that structure before. Utah will argue it applies here.

The complaint's theory is worth reading carefully, because it reaches further than most state enforcement actions have. Utah is not only alleging that Kalshi operated unlawfully — it is alleging that the two Susquehanna entities named as defendants participated in unlawful transactions by providing liquidity. If that theory survives a motion to dismiss, it reframes what market-making means in this context. A firm that provides liquidity to a federally regulated exchange does not typically expect to answer to state gambling statutes. The question of whether state law can reach that far has not been decided.

Kalshi's preemption argument has a structural problem that the size of any individual lawsuit does not resolve. Preemption under the Commodity Exchange Act is express in some provisions and implied in others. The CFTC's authority over designated contract markets is clear. What is less clear is whether that authority was intended by Congress to displace state-level prohibitions on participation, rather than state-level regulation of the exchange itself. The legislative history of the Commodity Exchange Act and the Dodd-Frank amendments that followed does not provide a clean answer on this point, and the courts have not produced one.

I think the consensus read — that Kalshi's federal charter insulates it from state enforcement — understates how seriously a court with a constitutional prohibition in front of it will take the preemption question. The Supremacy Clause argument works cleanly when federal and state law regulate the same activity in incompatible ways. It works less cleanly when a state is not trying to regulate the exchange but to prohibit its residents from using one. Those are not identical claims, and Utah's constitutional structure gives its version of the argument more force than a statutory prohibition would.

The legal standard that governs is whether Congress, in enacting the Commodity Exchange Act and its amendments, expressed a clear intent to preempt state laws that prohibit residents from engaging in contracts on designated markets. That intent must appear in the statute's text, structure, or legislative history. It does not appear plainly in any of them.
