Arizona AG files charges against Kalshi over ‘illegal gambling’

Arizona Attorney General Kris Mayes just dropped the hammer — her office filed gambling and related criminal charges against the companies behind prediction markets platform Kalshi. This isn't just a slap on the wrist; it's a full-blown legal showdown.

In a Tuesday notice, Mayes said the charges allege Kalshi operated an “illegal gambling business in Arizona without a license” and offered election wagering, straight-up violating state laws. Arizona authorities claim Kalshi’s platform let residents bet on event contracts for sports and state/federal elections. AG Mayes didn't hold back: “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.”

According to the AG’s office, these charges came after Kalshi filed its own lawsuit against Arizona “preemptively in an attempt to avoid accountability under Arizona law.” This is part of a pattern — states like Utah have filed similar lawsuits against prediction market platforms like Polymarket and Kalshi.

Kalshi’s response? Absolute fire. A spokesperson told Cointelegraph: “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. 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.”

The legal battlefield is messy. Last week, an Ohio judge denied Kalshi’s request for a preliminary injunction in a similar case, saying the company failed to show its sports event contracts were under the “exclusive jurisdiction” of the Commodity Futures Trading Commission (CFTC). But in February, a federal judge in Tennessee blocked state authorities from enforcing gambling laws against Kalshi. It's a jurisdictional tug-of-war.

Now the sole commissioner on the CFTC since acting chair Caroline Pham stepped down in December, Chair Michael Selig has publicly said the federal regulator would defend prediction market platforms from state-level lawsuits. He's not just talking — last week, Selig opened a proposed rule up to public comment on how the Commodity Exchange Act applies to prediction markets, potentially changing how the agency approaches regulation and enforcement. This could be a game-changer.
