Arizona authorities have escalated their dispute with prediction market platform Kalshi by filing criminal charges, marking a significant development in an ongoing legal conflict over the company’s operations in the state.

The Arizona Attorney General’s Office announced Monday that it had brought a 20-count misdemeanor indictment against KalshiEx LLC and Kalshi Trading LLC. Officials allege the companies have been running what amounts to an unlawful gambling enterprise while presenting it as a prediction market.

Sixteen of the counts relate to betting and wagering offenses, while the remaining four involve election wagering, which state law separately prohibits. According to the filing (pdf), Arizona regulations forbid operating an unlicensed wagering business and explicitly ban betting on elections.

Attorney General Kris Mayes made the state’s position clear in a public statement quoted by KTAR News: “Kalshi may brand itself as a ‘prediction market,’ but what it’s actually doing is running an illegal gambling operation and taking bets on Arizona elections, both of which violate Arizona law. No company gets to decide for itself which laws to follow.”

Legal Dispute Intensifies Across Courts

The criminal case comes shortly after Kalshi initiated its own legal action. On March 12, the company filed a lawsuit in federal court seeking to block Arizona officials from enforcing restrictions against its platform. The company argued that it faced a “substantial risk” of enforcement action if it continued operating in the state.

Kalshi also requested immediate relief through a temporary restraining order, though that request was denied. A hearing on its motion for a preliminary injunction is scheduled for April 3.

The legal tension between the two sides has built over several months. In May 2025, Arizona Department of Gaming Director Jackie Johnson issued cease-and-desist notices to Kalshi and Crypto.com after they began offering contracts tied to sports events. Regulators argued that these offerings resembled unlicensed betting activity.

Johnson had previously cautioned gaming license holders that participating in event contract markets without proper authorization could jeopardize their licenses. She also indicated that activities outside Arizona could still factor into regulatory decisions within the state.

Kalshi’s legal strategy has extended beyond Arizona. The company has filed similar preemptive lawsuits against Utah and Iowa in recent weeks, reflecting a broader effort to challenge state-level enforcement actions.

Disagreement Over Regulation and Oversight

At the center of the dispute lies a fundamental disagreement about how prediction markets should be regulated. These platforms allow users to trade contracts based on the likelihood of future events, ranging from weather outcomes to geopolitical developments, with sports markets forming a large share of activity.

Kalshi maintains that its operations fall under federal oversight through the Commodity Futures Trading Commission (CFTC), which currently permits prediction markets to operate nationwide as legal questions continue through the courts.

Arizona officials, however, contend that the platform’s offerings violate state gambling laws. Mayes emphasized that the state will continue to enforce its regulations, stating, “Arizona will not be bullied into letting any company place itself above state law.”

She also criticized Kalshi’s legal approach, adding, “Kalshi is making a habit of suing states rather than following their laws. In the last three weeks alone, the company has filed lawsuits against Iowa and Utah, and now Arizona. Rather than work within the legal frameworks that states like Arizona have established, Kalshi is running to federal court to try to avoid accountability.”

Kalshi has pushed back against the accusations. Elisabeth Diana, the company’s Head of Communications, disputed the strength of the case, saying, “Sadly, a state can file criminal charges on paper-thin arguments. States like Arizona want to individually regulate a nationwide financial exchange, and are trying every trick in the book to do it.”

She also reiterated the company’s stance on federal jurisdiction, stating, “As other courts have recognized and the CFTC affirms, Kalshi is subject to federal jurisdiction. It’s different from what sportsbooks and casinos offer their customers, and it should not be overseen by a patchwork of inconsistent state laws.”

Broader Implications for Prediction Markets

Arizona is among several states taking steps to restrict or ban prediction markets, even as the federal government, including support from the Trump administration, has backed their operation under CFTC oversight.

The outcome of the legal battles could shape how these platforms function across the United States, particularly in states where sports betting is legal but tightly regulated.

For now, the conflict between Arizona and Kalshi continues on multiple legal fronts, with both sides asserting authority over how such markets should be classified and controlled. The pending court decisions may determine whether prediction markets remain under federal jurisdiction or face stricter state-level enforcement.
