- The Commodity Futures Trading Commission, which regulates Kalshi, declared that criminal charges are “entirely inappropriate” for this dispute.

Prediction trading platform Kalshi now finds itself embroiled in significant legal trouble following Arizona’s decision to file 20 criminal charges against the company. Attorney General Kris Mayes claims Kalshi operates an unlawful gambling business without proper licensing and permits election betting within state borders.
CEO and co-founder Tarek Mansour didn’t wait long to respond. Speaking with Bloomberg, he characterized the charges as a “total overstep” and insisted they have “nothing to do with gambling.” Mansour suggested Arizona officials were attempting to circumvent existing litigation that Kalshi had initiated against state regulators.
Kalshi operates as a platform where participants trade contracts based on real-world outcomes including elections, sporting events, and economic indicators. The company maintains these represent event-based contracts rather than gambling products, placing them firmly under federal jurisdiction administered by the Commodity Futures Trading Commission (CFTC).
The CFTC, currently led by Chairman Michael Selig — a Trump administration appointee — has indicated favorable views toward prediction markets. Selig addressed Arizona’s charges through social media, characterizing the matter as a “jurisdictional dispute” and declaring criminal prosecution “entirely inappropriate.” He confirmed the commission is monitoring developments and evaluating potential responses.
Multi-State Legal Confrontation Expands
Arizona isn’t acting alone in challenging Kalshi. New York, Tennessee, and Massachusetts have each pursued various legal measures against the platform. Most actions have taken the form of cease-and-desist directives, civil complaints, or requests for injunctive relief. Arizona’s decision to pursue criminal prosecution represents the most aggressive state response to date.
Legal analyst Aaron Brogan, who founded Brogan Law, explained to CoinDesk that the situation illustrates a fundamental tension. He noted that states generating revenue through gambling regulation and taxation have economic incentives to contest federally supervised prediction markets that function beyond their regulatory reach.
“This is a dispute between the federal government and state government and that’s where it should be determined,” Brogan said.
Judicial rulings have produced inconsistent results. A Tennessee court prevented state officials from applying gambling statutes to Kalshi in February. However, an Ohio judge recently rejected a preliminary injunction motion built on Kalshi’s argument favoring CFTC jurisdictional authority.
The Jurisdictional Question at the Heart of the Dispute
The fundamental issue centers on whether federal regulations supersede state gambling statutes for platforms operating like Kalshi. Kalshi contends the CFTC possesses complete and exclusive regulatory power over its offerings. Arizona maintains that state legislation remains applicable.
Kalshi and competing platform Polymarket collectively account for over 90% of prediction market trading by notional volume, based on information from analytics provider Dune. How this legal conflict resolves could reshape the entire sector.
Mansour stated Kalshi intends to vigorously contest the charges and will “abide by court decisions.” He also implied the Arizona prosecution stems partially from political motivations and media pressure rather than genuine legal foundations.
The dispute’s progression will unfold through judicial proceedings, where courts must determine the boundaries between federal and state regulatory authority.
