Arizona AG Targets Kalshi: Is Event Trading Illegal Gambling?
Arizona Attorney General Kris Mayes has filed criminal charges against Kalshi, a prominent prediction market platform, and its co-founders, Tarek Mansour and Hooman Mohammadi. The charges include operating an illegal gambling enterprise and illegal control of an enterprise, stemming from Kalshi’s operations within Arizona.
At the heart of the dispute is Kalshi’s business model, which allows users to engage in event contracts — essentially betting on the outcomes of real-world events. Examples cited include predicting whether the average temperature in Phoenix will exceed 95.9 degrees Fahrenheit in July 2024, or if the S&P 500 will close above a certain threshold on a specific date. The Arizona AG contends that these activities constitute illegal gambling under state law.
Kalshi, however, asserts that it operates under the exclusive jurisdiction of the Commodity Futures Trading Commission (CFTC), which approved its event contracts. A Kalshi spokesperson characterized the criminal case as based on “paper-thin arguments” and maintained the company is exclusively under federal oversight, arguing that CFTC approval preempts state regulations.
This claim of federal preemption is a critical point of contention. The Arizona AG argues that even with CFTC approval, state criminal statutes against gambling remain applicable. This legal battle highlights a broader regulatory gray area, as the CFTC itself has seen internal dissent regarding Kalshi’s products; Commissioner Christy Goldsmith Romero notably expressed concerns in 2022, questioning if these contracts lacked genuine economic purpose and were suitable for retail investors, effectively labeling them as potential gambling.
The outcome of this case could establish a significant precedent, potentially impacting the regulatory landscape for prediction markets and other financial derivatives across the United States. It underscores the challenges of applying traditional gambling laws to novel financial instruments, particularly when federal and state jurisdictions clash over what constitutes legitimate trading versus illegal wagering. Kalshi profits by charging a small fee, typically between 0.5% and 2%, on each trade.
