A federal judge has temporarily barred Arizona from enforcing its gambling laws against prediction market operators, halting a criminal case brought against Kalshi by state prosecutors.
US District Judge Michael Liburdi issued the ruling on Friday, which also pauses the arraignment hearing scheduled for Monday. A prosecutor confirmed the hearing will not take place.
Liburdi stated he would provide his reasoning in a written order, expected to be released on Friday evening. The decision comes after the Trump administration filed a lawsuit challenging Arizona's actions against predictive markets.
