Federal Judge Rules Utah Anti-Gambling Laws Apply to Kalshi Sports Betting Contracts

A federal judge ruled Tuesday that Utah can enforce its anti-gambling laws against Kalshi, dealing a significant blow to the prediction market operator’s argument that federal oversight shields its sports contracts from state regulation. U.S. District Judge Robert J. Shelby granted summary judgment to Utah, rejecting the lawsuit Kalshi filed against the state in February and ordering the case closed.

Kalshi had argued that its status as a federally registered exchange, regulated by the Commodity Futures Trading Commission, prevented Utah from treating its sports-related event contracts as illegal gambling under state law. Shelby disagreed, finding that the Commodity Exchange Act does not override a state’s traditional authority to ban gambling within its borders.

What the Judge Said

In his ruling, Shelby wrote that “given the [Commodity Exchange Act’s] framework and the history of State regulation of gambling, the court cannot conclude the CEA is so pervasive that there is no room for the State of Utah to supplement it.” He added that the federal law Kalshi relied on “does not preempt Utah’s ability to enforce its anti-gambling laws.”

The judge also pushed back on the idea that complying with both federal and state rules would be unworkable for Kalshi, noting that “adding an additional category of prohibited participants in a sports-related event contract does not appear to be onerous.” Shelby’s opinion pointed to a long history of states regulating gambling, a power he said Congress has recognized since the early 1800s, and reasoned it would be “inconsistent for Congress to allow States to regulate their gambling laws but to simultaneously require States to provide citizens access to every event contract, including those that constitute gambling under State law.”

Kalshi sued Utah in February after state lawmakers passed a law adding proposition bets to the state’s legal definition of gambling, a move the company said threatened it with potential criminal enforcement. Shelby also found that enforcing state gambling laws “is not inconsistent with the CFTC’s regulation and oversight of derivatives markets,” reasoning that Congress is aware some states permit gambling while others do not, and that the Commodity Exchange Act explicitly leaves room for state jurisdiction on the topic. A spokesperson for Kalshi said the company disagrees with Tuesday’s decision and plans to appeal, maintaining that “multiple courts have already recognized that prediction markets fall under exclusive federal jurisdiction” and pledging to “continue to defend that position.” Utah officials, meanwhile, framed the outcome as validation of the state’s approach, with one saying the ruling “affirms that Utah’s anti-gambling laws are an appropriate way to protect our citizens and are not preempted by federal law.”

How We Got Here

Kalshi has built its sports betting-adjacent business around “event contracts,” financial instruments that let users take positions on the outcomes of games and other events. Because Kalshi is registered with the CFTC as a designated contract market, the company has argued nationwide that its products should be treated as regulated derivatives rather than as wagers subject to state gaming law and licensing requirements. That argument has produced wildly different results depending on the courtroom.

Part of a Bigger, Messier Legal Fight

The Utah decision lands in the middle of a fractured national legal landscape over whether sports event contracts are federally regulated financial products or state-regulated sports betting in disguise. Kalshi has notched wins elsewhere, most notably a 2-1 ruling from the U.S. Court of Appeals for the Third Circuit in April that upheld a preliminary injunction blocking New Jersey from enforcing its gambling laws against the platform. That panel found Kalshi’s sports contracts qualify as “swaps” under the CEA and are shielded by federal preemption, though a dissenting judge argued state gambling laws should still apply.

Similar preemption fights are playing out in the Fourth, Sixth and Ninth Circuits, while the CFTC itself has taken an aggressive stance defending what it calls its “exclusive jurisdiction” over event contracts, filing federal lawsuits against states including Arizona, Connecticut, Illinois and, most recently, New Mexico. States have pushed back with cease-and-desist orders and, in Arizona’s case, a criminal prosecution against a Kalshi-linked operator. The result is a patchwork where Kalshi’s sports contracts may be legal in one federal circuit and treated as illegal gambling in another, all while the underlying legal question awaits a definitive answer from a higher court or Congress.

For sports bettors and operators watching the space, the Utah ruling is a reminder that prediction markets remain a legal gray zone rather than a settled alternative to regulated sportsbooks. Anyone placing wagers should stick to licensed sportsbooks that operate under clear state regulatory frameworks rather than platforms still fighting in court over their basic legal status.

What Comes Next

With the case closed at the district court level, the fight now heads to appeal, where Kalshi will try to replicate the outcome it secured in New Jersey. Given the conflicting rulings already on the books across multiple circuits, legal observers expect the issue to eventually require intervention from a federal appeals court decision that carries broader precedent, or possibly the U.S. Supreme Court, before the question of whether prediction markets can offer sports contracts nationwide is fully resolved.
