In a recent ruling, a federal judge in Arizona has granted a temporary restraining order, preventing the state from pursuing criminal charges against prediction market provider Kalshi. The decision comes after the Commodity Futures Trading Commission (CFTC) filed a motion to block Arizona's actions. According to the ruling, Arizona's gambling laws may be preempted by federal law, and the state's pursuit of criminal charges could violate the Supremacy Clause.
The CFTC has argued that prediction markets, also known as event contracts, fall under its supervision as swaps, and that federal law takes precedence over state law. The case is part of a larger dispute between the CFTC and several states, including Arizona, over the regulation of prediction markets.
The ruling has been welcomed by the CFTC, with Chair Michael Selig stating that it sends a clear message that states cannot use criminal law to intimidate companies that comply with federal regulations. The temporary restraining order will remain in place for two weeks, and a hearing on a preliminary injunction is scheduled to take place soon.
