The state of Arizona has filed the first criminal charges against prediction market platform Kalshi, alleging it operates an illegal gambling business. Arizona Attorney General Kris Mayes announced the 20-count complaint on March 17, 2026, marking a significant escalation in the legal battle between states and the prediction market industry.
Charges Allege Illegal Gambling and Election Bets
The complaint, filed in Maricopa County court, accuses Kalshi of engaging in unlicensed gambling activities and accepting wagers on political elections. State law prohibits both practices. “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,” Attorney General Mayes said in a statement.
The charges include four specific counts of election wagering. These relate to bets accepted from Arizona residents on the 2028 presidential race, the 2026 Arizona gubernatorial race, the 2026 Arizona Republican gubernatorial primary, and the 2026 Arizona Secretary of State race. The charges are classified as misdemeanors.
Kalshi’s Legal Counter-Offensive
Kalshi had already initiated its own legal action against Arizona before the criminal filing. The company sued the Arizona Department of Gaming in federal court on March 12. Its lawsuit argues that Arizona’s regulatory efforts intrude “into the federal government’s exclusive authority to regulate derivatives trading on exchanges.”
Kalshi has filed similar lawsuits against Iowa and Utah in recent weeks. Attorney General Mayes criticized this strategy. “Kalshi is making a habit of suing states rather than following their laws,” Mayes stated. “Rather than work within the legal frameworks that states like Arizona have established, Kalshi is running to federal court to try to avoid accountability.”
Company Calls Charges ‘Seriously Flawed’
Kalshi’s head of communications, Elisabeth Diana, strongly disputed the Arizona charges. She called them “seriously flawed” and an act of “gamesmanship” connected to the company’s ongoing litigation against the state.
“Four days after Kalshi filed suit in federal court, these charges were filed to circumvent federal court and short-circuit the normal judicial process,” Diana said. “They attempt to prevent federal courts from evaluating the case based on the merits – whether Kalshi is subject to exclusive federal jurisdiction. These charges are meritless, and we look forward to fighting them in court.”
Federal vs. State Regulatory Showdown
The conflict centers on a fundamental jurisdictional dispute. Kalshi and similar platforms argue they are subject to federal oversight by the Commodity Futures Trading Commission (CFTC), not state gambling laws. Federal officials have recently signaled support for this position.
CFTC Chair Mike Selig published an op-ed in the Wall Street Journal accusing state governments of undermining the agency’s authority. Selig claimed the CFTC would no longer “sit idly by while overzealous state governments” challenged its “exclusive jurisdiction” over the prediction market industry.
This stance sets up a direct regulatory clash. States like Arizona assert their traditional police powers to regulate gambling within their borders, while federal regulators claim supremacy over financial derivatives markets.
Broader Context of State Actions
Arizona’s criminal complaint is not an isolated action. It follows a series of cease-and-desist letters, lawsuits, and other official challenges from multiple states concerning Kalshi’s operations. State officials across the country have repeatedly argued that prediction markets are skirting local gambling regulations.
Prediction markets allow users to buy and sell contracts based on the outcome of future events, from election results to economic indicators. Proponents view them as valuable information aggregation tools, while critics see them as thinly veiled gambling platforms.
What Happens Next
The legal proceedings will now unfold on parallel tracks. The state-level criminal case will proceed in Maricopa County court, while Kalshi’s federal lawsuit challenging Arizona’s regulatory authority will move forward in the U.S. District Court. The outcome could establish a critical precedent for whether prediction markets are governed by federal financial regulators or state gambling commissions. The resolution of this jurisdictional fight will shape the future legality and operation of the entire prediction market industry in the United States.
