Kalshi challenges Arizona regulators, seeks injunction over prediction market crackdown

Kalshi is asking a federal judge in Arizona for permission to submit an unusually long legal motion as it seeks a preliminary injunction as part of emergency relief in a growing dispute with state regulators.

The derivatives trading platform filed the request Friday (March 13) in the U.S. District Court for the District of Arizona. The company says it intends to request both a temporary restraining order and a preliminary injunction aimed at blocking enforcement actions by the Arizona Department of Gaming and other state officials.
