The U.S. Commodity Futures Trading Commission has sued Utah and Attorney General Derek Brown, escalating a legal fight over prediction markets and whether states can restrict them. The suit follows remarks by Utah Attorney General Derek Brown that he would pursue Kalshi and affiliated entities over allegations they generated as much as $60 million in profit through illegal event betting. In a Monday filing in the U.S. District Court for the District of Utah, CFTC lawyers argued Utah is trying to bypass the intent of Congress to create a single federal framework for commodity derivatives. The regulator says state restrictions intrude on markets it regulates.
Key points: The CFTC is suing Utah and Derek Brown, arguing the state is interfering with CFTC-regulated exchanges and federally approved products. Utah centers its case on prediction markets and claims Kalshi and affiliates obtained up to $60 million in profit illegally. CFTC Chair Michael Selig says the regulator has exclusive jurisdiction over prediction markets, a position that has fueled repeated federal-versus-state disputes. Courts, and possibly the U.S. Supreme Court, may ultimately decide how far states can go in overseeing event-contract trading.
Utah moved to stop Kalshi, and the CFTC responded. The federal lawsuit follows a week of escalating actions after Utah officials announced legal action against Kalshi and related entities. The CFTC says Utah is trying to impose state restrictions on exchanges that operate under the CFTC regulatory umbrella. At the center is the classification of certain event contracts offered through exchanges registered with the CFTC. The regulator says these contracts meet the federal definition of swaps under the Commodity Exchange Act. In its filing, the CFTC says the event contracts Utah targeted are swaps under federal law and that the venues offering them are CFTC-regulated Designated Contract Markets. The CFTC argues Utah is attempting to limit activities that Congress intended to be governed exclusively at the federal level, intruding on the exclusive federal scheme for U.S. commodity derivatives markets. The regulator frames the case as a jurisdictional conflict over whether federal approval and supervision are subject to a state veto.
Kalshi has denied wrongdoing. Kalshi spokesperson Jacki McGavick said in an emailed response to Cointelegraph that the platform answers to federal oversight and that no single state should have a veto over it. The dispute fits a broader pattern: multiple states have challenged prediction markets, while the CFTC maintains it has authority under federal law. CFTC Chair Michael Selig has argued for months that the regulator has exclusive jurisdiction over prediction markets, and this case is another test of that claim. For market participants, the battles create uncertainty about where platforms can operate cleanly. Even if a product is cleared under federal supervision, possible state-level actions can raise legal risk and operational friction, especially for platforms that rely on interstate participation.
The CFTC lawsuit adds to a growing list of federal and state cases targeting prediction market activity and oversight. The legal questions may ultimately require a Supreme Court resolution because they hinge on the boundary between state authority and federal regulation. Last September, New Jersey officials petitioned the Supreme Court to weigh in on their dispute involving Kalshi, describing a conflict similar to cases pending elsewhere. State-level efforts have also been brought in Michigan, Ohio, Kentucky, Nevada, Massachusetts, Wisconsin and New York. As of Tuesday, the Supreme Court had not announced whether it would hear the New Jersey matter. That decision could shape how lower courts treat the continuing wave of state suits and clarify whether the federal regulatory scheme fully displaces state restrictions. Until then, platforms such as Kalshi face the possibility of inconsistent rulings across jurisdictions, even as the underlying market structure remains subject to federal oversight. Investors and users should watch not only court outcomes but also how judges interpret the CFTC exclusive jurisdiction argument and whether they view state actions as compatible with federal law. With the CFTC now directly challenging Utah in federal court, the next key development will be how the District of Utah handles the jurisdictional issues, especially whether the case is treated as an obstacle to the CFTC regulatory scheme or as a legitimate state enforcement effort. Whether the Supreme Court will intervene remains the biggest wildcard in determining whether these conflicts converge into a single national rule.
