In a significant ruling, a federal judge in Arizona has temporarily barred the state from pursuing 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 CFTC's motion, stating that Arizona cannot proceed with an arraignment of Kalshi as scheduled. This move is a result of the CFTC's claim that Arizona's gambling laws are preempted by the Commodity Exchange Act.
The judge noted that allowing Arizona to proceed with state action could violate the Supremacy Clause, leading to a temporary restraining order for two weeks. A pending motion for a preliminary injunction may extend this order. The CFTC Chairman, Michael Selig, welcomed the judge's decision, emphasizing that using state criminal law against companies complying with federal law sets a dangerous precedent. The ruling is part of an ongoing dispute between the CFTC and several states, including Arizona, regarding the regulation of prediction markets.
While state courts have often sided with states, federal courts have shown mixed results. The CFTC argues that prediction markets are subject to its supervision, while states claim they fall under their jurisdiction. The Ninth Circuit Court of Appeals is set to hold a hearing on a consolidated case, allowing providers and other parties to present their arguments. Judge Liburdi's decision to block Arizona's action against Kalshi comes after denying Kalshi's own motion for a preliminary injunction against the state, with the parties arguing on different grounds.
