Federal judge blocks Arizona’s prosecution of Kalshi

A federal judge blocked Arizona from prosecuting Kalshi and other CFTC-regulated prediction markets, citing federal preemption over state gambling laws.

A federal judge has temporarily blocked Arizona from pursuing criminal charges against prediction market provider Kalshi and other federally regulated platforms. The court issued a temporary restraining order, halting Arizona’s planned arraignment and prohibiting enforcement of state gambling laws against contracts listed on Commodity Futures Trading Commission (CFTC)-regulated designated contract markets. This move follows the CFTC’s legal challenge, which asserts that federal law grants it exclusive authority over event contracts, preempting state gambling statutes. The case underscores a growing legal divide between state-level gambling regulations and federal oversight of derivatives and prediction markets, particularly those connected to crypto trading. The CFTC has also filed similar lawsuits against Connecticut and Illinois, signaling an escalation in the federal effort to assert jurisdiction over such markets. The court’s decision marks a significant development in the ongoing clash between innovative financial products and traditional state regulatory frameworks.
