Arizona judge grants Kalshi preliminary injunction in state dispute
A US district court judge granted Kalshi a preliminary injunction in its dispute with Arizona Attorney General Kristin Mayes and the Arizona Department of Gaming, reversing an earlier denial. The judge found Kalshi likely to succeed on its argument that federal law pre-empts state gambling enforcement against its event contracts; the injunction allows it to continue operating in Arizona while the case proceeds.
The injunction lets Kalshi continue operating in Arizona during litigation over state authority to regulate its event contracts.
