CFTC names Utah Attorney General in tenth state preemption suit

Spencer Cox called it a joke. The CFTC's answer arrived in the US District Court for the District of Utah, Central Division, with Derek Brown named as a defendant alongside the state itself.

The filing is the Commission's tenth preemption action against a state that has moved to restrict prediction market operators — and the first against a state with a Republican governor. That detail matters to the litigation map. The prior nine actions ran against states whose administrations were, at minimum, less ideologically aligned with a Trump-era CFTC. Chair Michael Selig now has to defend the same federal authority claim in territory where his own political coalition is the adversary. His statement did not soften for the geography: Utah, he said, seeks to shut down prediction markets across a wide variety of markets, and Congress entrusted the Commission with sole responsibility to oversee them.

The state's position, filed last week, is that Kalshi is running an illegal gambling operation — a public nuisance causing ongoing harm — in violation of Utah statutes covering sports, elections, and political betting. Kalshi's spokesperson Jacki McGavick responded that the company answers to federal law and that no single state should hold veto power over a federally regulated exchange. That framing is not new. It is the preemption argument the Commission has made in nine prior courts, and the argument that has survived initial challenge in several of them.

The legal question underneath all of it is not whether Kalshi is a good actor or a bad one. It is whether the Commodity Exchange Act's grant of exclusive jurisdiction to the CFTC over designated contract markets displaces state gambling law when the two conflict. The Supremacy Clause makes that a tractable question, but not a simple one. States have historically held broad police powers over gambling within their borders, and those powers do not evaporate because a federal agency has decided a given instrument is a commodity derivative. The circuit courts have not yet produced a definitive answer, and New Jersey's petition asking the Supreme Court to take the question suggests the circuits may not get there first.

What has shifted with this filing is the political texture of the litigation. The prior nine cases let state officials frame the CFTC as a federal regulator overriding local democratic choices on a culturally charged issue. A Democratic governor opposing a Trump appointee's jurisdictional land-grab is a legible political story. Cox opposing Selig is the same structural claim in the opposite costume, and that creates pressure on both sides that the earlier filings did not.

The preemption standard the courts will apply comes from the Supremacy Clause and the Commodity Exchange Act's express jurisdictional language at 7 U.S.C. § 7a-3. The test is whether Congress intended the federal scheme to occupy the field, or whether it left room for concurrent state authority. Express preemption language, where it exists, ends that inquiry early. What the courts will read is whether the Act's grant to the CFTC is exclusive in the sense that forecloses state enforcement — not merely in the sense that creates a parallel federal option.
