A federal judge in Arizona has temporarily stopped state officials from enforcing gambling laws against Kalshi, a prediction market platform regulated by the Commodity Futures Trading Commission. Summary A federal judge paused Arizona action against Kalshi and backed the CFTC’s jurisdiction argument. The restraining order blocks Arizona enforcement until April 24 as the case moves forward. State and federal officials remain split on whether event contracts are swaps or gambling. The ruling adds to the legal fight over whether event-based contracts should be treated as financial products under federal law or as gambling under state rules. The order came from Judge Michael Liburdi of the US District Court for the District of Arizona. The court granted a request from the CFTC and the federal government to pause Arizona’s action while the case moves ahead. The restraining order will stay in place until April 24 as the court considers the next step. Court backs CFTC position The case centers on Kalshi’s event contracts, which let users trade on the outcome of real-world events. The CFTC argued that these products qualify as swaps under the Commodity Exchange Act and therefore fall under federal oversight rather than state gambling law. The court said the federal government is likely to succeed on that argument. That finding led the judge to block Arizona from starting or continuing civil or criminal action tied to contracts listed on CFTC-regulated markets. The ruling also paused Arizona’s criminal case against Kalshi. Additionally, Arizona had moved against Kalshi under state gambling rules and filed criminal charges tied to event-based trading. State prosecutors argued that Kalshi was offering unlawful betting products, including contracts tied to political events and sports outcomes. After the CFTC stepped in, the federal court halted that effort. The order means Arizona officials cannot continue enforcement tied to Kalshi’s contracts during the current restraining period. Reports also said a scheduled arraignment was called off after the ruling. Wider fight over prediction markets The Arizona case is part of a wider dispute over prediction markets in the United States. On April 6, a federal appeals court ruled that New Jersey could not restrict Kalshi’s sports-related event contracts, finding that the CFTC has exclusive jurisdiction over those products. Other states have taken a different view. In Nevada, a judge last week extended a ban on Kalshi’s event contracts, saying the products were close enough to sports betting to fall under state gaming law. Utah lawmakers have also moved against proposition-style event markets. Those split outcomes show that the legal fight over Kalshi and similar platforms is still active. Furthermore, the latest order gives Kalshi temporary relief, but it does not settle the full dispute. The larger question is whether platforms offering these contracts operate as regulated exchanges or as betting businesses under state law.
