  • Arizona has escalated its case against Kalshi by filing criminal charges over alleged illegal gambling activity.
  • Kalshi argues the case is a jurisdictional overreach and part of a broader fight over regulatory control.
  • The dispute highlights tension between state gambling laws and federal oversight via the CFTC.

Kalshi is pushing back against criminal charges filed in Arizona, with co-founder Tarek Mansour accusing state authorities of overreach and arguing the case is aimed at undermining a federally regulated marketplace.

Arizona Attorney General Kris Mayes has brought 20 criminal counts against the company, alleging it operated an illegal gambling business and enabled betting on elections and sporting events in violation of state law. Mayes has said the state will enforce its laws against unlicensed wagering activity.

Mansour has countered that the charges are not about gambling, but instead represent an effort to disrupt an ongoing legal battle over who has authority to regulate prediction markets. He has also argued that the move attempts to bypass judicial processes already underway.

At the core of the dispute is Kalshi’s position that its contracts fall under the oversight of the CFTC, which regulates derivatives markets at the federal level. The company describes its platform as a financial exchange where users trade outcome-based contracts rather than placing bets against a bookmaker.

Arizona’s case stands out as an escalation, shifting from the civil actions seen in other states to criminal prosecution. The broader conflict now involves multiple jurisdictions, reflecting a growing divide between state regulators and federal authorities.

CFTC Chair Mike Selig has described the matter as a jurisdictional dispute and criticised the use of criminal charges, indicating the agency is assessing its response.
