A U.S. District Judge in Arizona has issued a temporary injunction preventing the state from pursuing enforcement actions against prediction market platform Kalshi. Judge Michael Liburdi's ruling, delivered on April 11, stops Arizona from applying state gambling laws to Kalshi's contracts, which are regulated by the U.S. Commodity Futures Trading Commission (CFTC). The decision also cancels a hearing that was scheduled for April 13. This move follows a motion by the CFTC, emphasizing federal oversight over state regulations in this context.
