CEO and co-founder Tarek Mansour swiftly fired back during a media appearance with Bloomberg. He characterized the criminal charges as regulatory overreach and insisted the case has no connection to gambling. Mansour claims Arizona officials are attempting an end-run around existing litigation that Kalshi initiated against state regulators.
The platform enables users to buy and sell contracts based on real-world outcomes including political elections, sporting events, and economic indicators. Kalshi maintains these represent event-based contracts subject to federal regulation, not gambling products under state control. Their regulatory oversight comes from the Commodity Futures Trading Commission (CFTC).
The CFTC’s current leadership under Chairman Michael Selig — a Trump administration appointee — has shown openness toward prediction market innovation. Selig weighed in on the Arizona prosecution via social media, framing it as a “jurisdictional dispute” where criminal charges were “entirely inappropriate.” He confirmed the agency is monitoring developments and considering response options.
The Arizona Attorney General today filed criminal charges against one of our registered exchanges related to prediction markets. This is a jurisdictional dispute and entirely inappropriate as a criminal prosecution. The @CFTC is watching this closely and evaluating its options.

Multi-State Enforcement Campaign Intensifies
Arizona represents just one front in a broader regulatory assault. State authorities in New York, Tennessee, and Massachusetts have initiated enforcement proceedings against Kalshi. These actions have primarily involved cease-and-desist directives, civil litigation, or requests for injunctive relief. Arizona’s decision to pursue criminal prosecution marks an escalation beyond what other states have attempted.
Aaron Brogan, a legal specialist and founder of Brogan Law, told CoinDesk the conflict reveals underlying tensions. He noted that states deriving revenue from regulated gambling industries have economic incentives to challenge federally-supervised prediction markets operating beyond their taxing authority.
“This is a dispute between the federal government and state government and that’s where it should be determined,” Brogan said.
Judicial outcomes have produced inconsistent results. A Tennessee court issued an order in February preventing state enforcement of gambling statutes against Kalshi. Conversely, an Ohio judge rejected Kalshi’s request for preliminary injunction last week, declining to accept the company’s federal jurisdiction arguments.
The Federal Versus State Authority Question
At the heart of this confrontation lies a fundamental question: do federal regulations supersede state gambling laws for platforms like Kalshi? The company asserts that CFTC authority is comprehensive and exclusive over its contract offerings. Arizona contends that state statutes remain applicable.
Kalshi and competitor Polymarket together account for over 90% of prediction market trading by notional volume, based on analytics from Dune. The legal resolution will likely establish precedent affecting the entire sector.
Mansour stated Kalshi intends to vigorously contest the charges and will “abide by court decisions.” He also implied that political considerations and media coverage influenced Arizona’s prosecution strategy rather than pure legal analysis.
The matter will advance through the court system, where judges must untangle the competing claims of federal and state regulatory power.
