Utah filed criminal charges on October 28, 2026 against prediction market platform Kalshi, its CEO and co-founder Tarek Mansour, and its chief operating officer and co-founder Luana Lopes Lara. The three are accused of promoting illegal online gambling, including an undercover agent placing bets on NFL games. The case goes well beyond one state: it sharpens a federal-versus-state fight over who regulates event contracts in the United States.
🔑 Key takeaways
- Fourteen criminal counts were filed in Salt Lake City, with 13 tied to violations of Utah’s online gambling ban, according to several outlets
- A parallel civil suit, filed October 20, 2026, targets KalshiEX LLC and related entities
- Kalshi denies the allegations and argues that the CFTC holds exclusive jurisdiction
- The CFTC sued Utah the day before the criminal filing, on October 27, 2026
- No share price, volume or market-cap reaction has been reported so far
A criminal case layered on top of a civil suit
The complaint was filed in a Salt Lake City court and names three individuals: the platform’s CEO and co-founder Tarek Mansour, and its chief operating officer and co-founder Luana Lopes Lara, alongside the company itself. The case comprises 14 counts in total. They are felonies, which carry the possibility of prison time, although the attorney general’s office has not said which penalties it intends to seek.
The Guardian, The Block and Seeking Alpha describe the case as 13 counts of violating the state’s ban on online gambling, plus one count of profiting from illegal activity. None of the sources lists the detailed legal titles of each count. The Guardian also reports that Kalshi kept operating in the state despite a federal ruling that Utah’s gambling laws applied to the platform.
In his statement, Utah Attorney General Derek Brown summarized the state’s position:
“Gambling is illegal in Utah, whether you place the bet, run the game, or promote it. Calling it a ‘prediction market’ doesn’t change what it is, and being federally registered doesn’t put a company above the law.”
Derek Brown, Attorney General of Utah
The criminal action follows a civil complaint filed on October 20, 2026 in a Utah court against KalshiEX LLC and related entities. It alleges that the platform allowed residents to bet on sporting events, elections, politics and other outcomes, in violation of state gambling law. Utah argues that describing these products as “event contracts” does not change their legal nature.
The civil complaint also characterizes the activity as a public nuisance causing ongoing and significant harm to Utah residents. The state asks the court to order Kalshi to stop offering these bets in the state, along with any other relief detailed in the filing. The local legal framework is unusually strict: the Utah constitution bars the Legislature from authorizing gambling, and state law makes the activity illegal. Brown stressed that Utah is one of only two states where gambling is also prohibited by the state constitution, a rule in place for 130 years. He also said that Kalshi “runs an online casino in Utah and calls it a prediction market.”
Conflicting counts across outlets
The number and breakdown of counts differ across sources. The table below summarizes the two readings available. In both cases, the total stands at 14 counts.
| Source | Count | Breakdown |
|---|---|---|
| The Guardian, Seeking Alpha, The Block | 13 + 1 | 13 counts of violating the online gambling ban, 1 count of profiting from illegal activity |
| Al Jazeera | 12 + 1 + 1 | 12 counts of promoting online gambling, 1 count of general gambling promotion, 1 count of “pattern of unlawful activity” |
The gap may reflect how each newsroom read the charging document, differences in how counts were labeled, or later updates to the case. Until the official filing is widely available, the only point all sources agree on is the total of 14 counts.
Penalties still unknown
None of the sources reports the potential penalty for each count or any fine amount. The prosecution has not disclosed its sentencing requests. Such details typically emerge only after the initial stage of the case, so their absence at this stage is not unusual.
A federal fight that extends well beyond Utah
On Tuesday, October 27, 2026, the day before the criminal filing, the Commodity Futures Trading Commission (CFTC) sued Utah. Its goal is to stop the state from enforcing its gambling rules against prediction markets. The agency argues that these markets fall under federal jurisdiction and that Utah is encroaching on that authority. CFTC Chairman Michael Selig defended the position:
“Congress entrusted the CFTC to be the federal regulator with sole responsibility to oversee these markets. As I’ve said before, the CFTC has the expertise and responsibility to defend its exclusive jurisdiction over commodity derivatives, and that’s exactly what we’ll do.”
Michael Selig, Chairman, CFTC
According to The Block, the CFTC had already sued at least ten states, Utah included. The Guardian puts the number of states involved in the litigation at roughly twenty. The two figures measure different things: one counts states targeted by the CFTC, the other counts all states taking part in the dispute. Al Jazeera adds that dozens of states, governed by both Republican and Democratic administrations, have argued that the CFTC lacks authority to regulate prediction markets.
Arizona sets an important precedent. In March 2026, it became the first state to file criminal charges against Kalshi over alleged illegal gambling operations. A federal judge later halted Arizona’s prosecution after the CFTC itself sued to stop states from regulating prediction market operators. The Utah case follows a similar sequence of events:
- February 2026: Kalshi sues Utah’s governor, attorney general and other state officials, invoking the federal Commodity Exchange Act.
- August 2026: Judge Robert Shelby grants Utah summary judgment, finding that federal law does not displace state gambling laws.
- September 8, 2026: the U.S. Court of Appeals for the Tenth Circuit declines to order Utah to stop enforcing its laws while the appeal is pending.
- October 27, 2026: the CFTC sues Utah.
- October 28, 2026: the state files criminal charges, with the appeal still pending.
The dispute could ultimately reach the U.S. Supreme Court, according to analysts cited by The Guardian. In the month before Utah’s announcement, New Jersey had already asked the high court to decide whether federal or state authorities hold jurisdiction over sports event contracts offered on prediction market platforms.
Kalshi’s response and open questions
Kalshi disputes the charges. A company spokesperson said: “This is a crazy overreach. Utah is clearly playing politics. We look forward to putting a stop to this in court, just like we did in Arizona.” The company maintains that prediction markets fall exclusively under federal jurisdiction and are not subject to state gambling laws.
Al Jazeera reported that neither Kalshi nor Brown’s office had immediately responded to its requests for comment, while the other outlets published statements from Brown and from Kalshi. The difference most likely reflects the timing of each outlet’s requests and responses rather than a substantive disagreement.
No source reports a change in Kalshi’s share price, trading volume or market capitalization after the announcement. The documented reactions are essentially legal and institutional: Utah’s charges, the CFTC’s federal action, Kalshi’s defense and New Jersey’s request before the Supreme Court. Any financial reading of the case is therefore speculative for now.
Three scenarios deserve close monitoring in the coming weeks:
- Scenario 1: the Utah court rules quickly on the civil complaint, strengthening the states’ hand over online gambling enforcement.
- Scenario 2: the Supreme Court takes up the jurisdictional question, with consequences for every state involved.
- Scenario 3: negotiations between the CFTC, the states and operators produce a shared framework, sidestepping a definitive court ruling.
Conclusion: a ruling that reaches beyond Kalshi
Beyond the fate of Kalshi and its executives, the case exposes a structural question: who holds authority over event contracts in the United States. If the courts side with Utah, states could extend their gambling rules to prediction markets, creating regulatory fragmentation for operators. If the CFTC prevails, its exclusive authority over commodity derivatives would be confirmed, at the cost of narrowing state powers.
The legal timetable remains uncertain. The Tenth Circuit appeal, the criminal and civil proceedings, and a possible Supreme Court petition could stretch over several months. Investors and observers should track procedural rulings rather than public statements to gauge the real trajectory of the case.
