In an unprecedented move, Arizona has launched criminal proceedings against prediction market operator Kalshi, marking the first time any state has pursued such charges against a platform in this industry. State prosecutors unveiled a 20-count criminal complaint on Tuesday, alleging the company facilitates an unlawful gambling enterprise.
State Attorney General Kris Mayes announced that Kalshi has been accepting wagers from Arizona citizens on political contests and athletic competitions, activities she maintains breach state statutes. Mayes emphasized that corporations cannot selectively choose which legal requirements to observe.
The criminal complaint encompasses four counts specifically targeting election-related wagering. These counts address contracts concerning the 2028 presidential election, Arizona’s 2026 governor’s race, the Republican primary for that gubernatorial contest, and the state’s 2026 Secretary of State election.
Additional counts pertain to wagering on major league and collegiate athletic events, along with proposition-style contracts on individual athlete statistics. One count references a contract on congressional passage of the SAVE Act.
Under Arizona law, each charge carries potential penalties ranging from $10,000 to $20,000. State authorities may additionally pursue confiscation of assets and judicial orders terminating Kalshi’s business activities.
Criminal proceedings expand prosecutors’ investigative capabilities substantially. Authorities gain subpoena power for corporate documentation and can mandate executive testimony under oath.
Federal Court Rejects Kalshi’s Intervention Attempt
The state’s criminal filing followed closely after Kalshi initiated its own legal challenge against Arizona authorities in federal district court on March 12. The company contended that the Commodity Exchange Act grants the CFTC sole regulatory authority over event-based contracts on supervised exchanges.
Kalshi maintained that Arizona improperly categorizes its regulated contracts as unlawful gambling activities. The platform argued that state actions following a May 2025 cease-and-desist directive demonstrated an imminent enforcement threat.
However, Kalshi’s federal litigation encountered immediate obstacles. U.S. District Judge Michael T. Liburdi dismissed the company’s temporary restraining order petition on the identical day criminal charges materialized.
Judge Liburdi additionally questioned whether federal jurisdiction applies at all. He directed Kalshi to submit briefing by March 20 explaining why the court should not invoke Younger abstention principles.
This established legal doctrine instructs federal tribunals to typically avoid interference with active state criminal prosecutions. Arizona’s response deadline is March 27, with oral arguments scheduled for April 3.
Should the federal court decline jurisdiction, Kalshi must defend against criminal allegations in Arizona’s state judicial system. Such a development might embolden additional states to pursue comparable enforcement against prediction market operators.
Kalshi’s Nationwide Legal Struggles Continue
Kalshi has encountered numerous legal challenges across multiple jurisdictions. Last week, an Ohio federal judge rejected the platform’s preliminary injunction motion, permitting state enforcement of sports wagering regulations against the company.
The operator has similarly experienced adverse rulings in Nevada and Massachusetts courts. A Maryland federal tribunal denied Kalshi’s preliminary injunction petition in August 2025.
Despite these setbacks, Kalshi has secured certain victories. A federal judge in Tennessee determined the company demonstrated substantial likelihood of proving its sports contracts constitute CFTC-regulated swaps. New Jersey’s federal court granted a preliminary injunction favoring Kalshi in April 2025.
Kalshi issued a response to Arizona’s criminal charges via social media platform X. The company labeled the prosecution “seriously flawed” and claimed state officials strategically timed the filing to “circumvent federal court and short-circuit the normal judicial process.”
CFTC Chairman Mike Selig publicly addressed the matter, characterizing Arizona’s criminal charges as “entirely inappropriate as a criminal prosecution.” He stated the regulatory agency is “watching this closely and evaluating its options.”
