In a recent ruling, a federal judge in Arizona has temporarily barred the state from filing criminal charges against Kalshi, a prediction market provider. The decision comes in response to a motion filed by the Commodity Futures Trading Commission (CFTC). District Judge Michael Liburdi granted the temporary restraining order, citing that the CFTC is likely to succeed in its claim that Arizona's gambling laws are preempted by federal law. This move prevents Arizona from proceeding with an arraignment scheduled for Kalshi, which the state had announced last month, alleging that Kalshi's offerings violated Arizona law.
The judge's ruling also noted that allowing Arizona to proceed with state action could violate the Supremacy Clause, and a pending motion for a preliminary injunction may extend the temporary order. The CFTC Chair expressed appreciation for the decision, stating that using state criminal law against companies complying with federal law sets a dangerous precedent. The case is part of a broader dispute over the regulation of prediction markets, with the CFTC arguing that these markets are subject to federal supervision. The ruling has significant implications for the ongoing debate between federal and state authorities regarding the oversight of event contracts and swaps.
