A federal judge, Michael Liburdi, has temporarily prevented Arizona from pursuing criminal charges against Kalshi, a prediction market provider, in a ruling issued on April 13. The state had intended to file 20 criminal charges against Kalshi, claiming the company was offering betting products in violation of Arizona law. The Commodity Futures Trading Commission (CFTC) intervened, arguing that prediction markets, also known as event contracts, are regulated at the federal level and should not be subject to state law enforcement. In his ruling, Judge Liburdi stated that Arizona is restrained from enforcing its gambling laws against Kalshi. CFTC Chair Michael Selig praised the decision, stating that using state criminal law against compliant companies sets a troubling precedent. The legal landscape surrounding prediction markets remains complex, with varying outcomes in state and federal courts. While some state courts have sided with state regulations, federal courts have shown support for the CFTC's authority over such markets.
