Kalshi vs. Utah: Who Gets to Decide What's Gambling?

Utah has moved its dispute with Kalshi from the civil courts into the criminal ones.

Prosecutors have filed 14 criminal charges against KalshiEX LLC and its two founders, Tarek Mansour and Luana Lopes Lara. The state accuses the company of illegally promoting gambling in Utah.

Kalshi is a federally regulated exchange in the United States. It lets users trade event contracts tied to binary real-world outcomes, such as elections, sporting results, economic data releases, and weather patterns.

The question at the center of this case is old and unresolved. Is a contract on the outcome of a game a financial derivative, or is it a bet?

The Charges

The 14 counts break down into three categories.

The most serious is a felony count alleging a pattern of unlawful activity. Alongside it sit 12 counts of promoting online gambling and one misdemeanor gambling charge.

The structure tells you how the state is framing the case. A single misdemeanor would treat the conduct as an isolated infraction. The felony count frames it as a course of activity, and the dozen promotion counts give that course of activity its substance.

Naming the founders personally matters too. This is no longer only a dispute about whether a company may operate in a state. Two individuals now face criminal exposure.

The Undercover Evidence

The prosecution rests on evidence gathered by an undercover agent from the Utah Attorney General’s Office.

In September, the agent accessed the platform using a local address, a local phone number and a debit card. Kalshi reportedly allowed the agent to place 12 distinct sports wagers.

The state claims those transactions prove the platform is actively promoting illegal gambling within Utah’s borders.

The design of that evidence is deliberate. Every identifier the agent used pointed to Utah. The aim is to remove any doubt about where the conduct took place and to show that a Utah resident could do exactly what the state says its law forbids.

The number of wagers also matches the number of promotion counts. How each count maps onto each transaction is a question the charging documents will have to answer, but the symmetry is hard to miss.

Two Tracks at Once

The criminal case did not arrive alone.

Days earlier, Utah’s attorney general filed a civil lawsuit against Kalshi. That suit seeks to stop the company from taking bets from Utah residents and to recover profits it allegedly made in the state.

Running civil and criminal proceedings side by side gives the state two different instruments. The civil case aims at the business itself: access to Utah users and the money earned from them. The criminal case aims at liability for past conduct, including the personal liability of the founders.

For a company, that combination raises the cost of litigating on principle. Every position it takes in one forum can echo in the other.

Kalshi’s Position

Kalshi’s argument has been consistent. The company has maintained that sports wagers traded on its platform are not gambling but a type of financial derivative. On that view, they fall under federal regulation by the Commodity Futures Trading Commission and should not be subject to state supervision.

Utah and several other states see it differently. They take the position that prediction markets like Kalshi are subject to state gambling laws and state gambling taxes.

Both positions cannot win. If these contracts are derivatives under federal oversight, state gambling statutes may have little room to operate. If they are bets, the federal label does not shield them from state law.

Washington Steps In

The CFTC has now entered the dispute directly. The agency has sued Utah, arguing that only Washington can regulate these contracts.

That changes the shape of the conflict. It is no longer only a state against a company. It is a federal regulator against a state, each asserting authority over the same product.

The criminal charges sharpen that collision. A state prosecuting a federally regulated exchange, while the federal regulator sues the state, puts the preemption question about as squarely as it can be put.

Utah Is Not Alone

Several other states, including Arizona, Connecticut, Massachusetts, Michigan and Nevada, have already chosen to file criminal charges, take civil action or restrict access to the platform within their borders.

The scrutiny also reaches beyond Kalshi. Polymarket has faced similar state level gambling allegations.

What emerges is a patchwork. A user’s access to the same contract can depend on which state line they happen to live behind, while the federal answer to the underlying question remains contested in court.

What to Watch

The case leaves several questions open.

The first is preemption: whether federal oversight of these contracts displaces state gambling law, which is the core of the CFTC’s suit against Utah. The second is how the criminal case proceeds alongside the civil one. The third is whether more states follow Utah from civil enforcement into criminal charges.

None of these has an answer yet. What is clear is that the classification of event contracts is no longer an abstract debate among lawyers. In Utah, it now carries criminal stakes.
