Kalshi’s two co-founders must appear in person before a Utah judge next month to face 14 criminal counts tied to alleged unlawful gambling — putting the executives themselves, not just the company, on the line. CEO Tarek Mansour and COO Luana Lopes Lara are due in Salt Lake City’s Third District Court on December 4 at 8:30 a.m. for an initial appearance and arraignment, according to sbcamericas.com and defirate.com.
Fourteen counts, one felony at the top
Utah officials filed the charges on October 28, days after launching a civil enforcement action earlier that month. The criminal case includes one count of a pattern of unlawful activity — a second-degree felony — plus twelve counts of online gambling promotion, each a third-degree felony, and a single count of general gambling promotion, a Class A misdemeanor, defirate.com reported.
Prosecutors built the case on an undercover operation. An investigator for the Attorney General’s office allegedly opened an account using a Utah address, a local phone number and a locally issued debit card, then placed 12 specific sports trades — transactions the state contends amount to unlawful gambling promotion inside its borders.

The criminal summons lands alongside a civil lawsuit Attorney General Derek Brown filed October 20 against Kalshi entities and two Susquehanna entities, alleging civil conspiracy, public nuisance, unjust enrichment and unlawful gambling, per defirate.com. Utah chose summonses rather than arrest warrants, but the personal criminal exposure for Mansour and Lara marks a sharp turn in the jurisdictional fight over event-based contracts.
CFTC and DOJ step in against the state
Washington has entered the fight. The Commodity Futures Trading Commission and the U.S. Department of Justice filed a complaint on October 26 seeking to block Utah from enforcing its gambling laws against federally regulated markets, defirate.com reported. On October 29, the federal plaintiffs moved for a preliminary injunction and a temporary restraining order to halt Utah’s enforcement.

At stake is a single question: does the Commodity Exchange Act preempt state gambling restrictions? Kalshi and the CFTC say Utah is improperly interfering with a federally regulated derivatives exchange. Utah maintains its constitution prohibits all real-money gambling.
Two earlier rulings frame the battle — and neither was decisive. In August, U.S. District Judge Robert J. Shelby rejected Kalshi’s attempt to hide behind federal law against state sports-contract restrictions. In September, the Tenth Circuit Court of Appeals denied Kalshi’s emergency request for an injunction, without settling the merits.
A rival clears federal hurdles while Kalshi fights
All eyes now turn to December 4. Whether Mansour and Lopes Lara’s arraignment in Salt Lake City sets a precedent for how state gambling laws reach event contracts could shape the sector for years.
