New Jersey's petition to the U.S. Supreme Court seeking review of its regulatory fight with Kalshi was formally docketed. Kalshi also lost court protection bids in Iowa and Utah. The state has asked the court to review the case via a writ of certiorari. Kalshi's chief regulatory officer discussed the petition with State Affairs. Kalshi has sued 15 states. No specifics on New Jersey's arguments or the Iowa and Utah rulings were available.

The docketed petition starts a clock where every month of cert consideration risks another state action against Kalshi. Nevada already stripped its federal shield, and Connecticut and Baltimore have parallel suits running. A Supreme Court grant would freeze state momentum and offer uniform federal rules; a denial leaves Kalshi fighting across multiple state gaming commissions with circuit precedent running against it. Traders hold positions whose legality shifts with state borders. Geofence costs multiply while legal spend compounds across cases that cannot resolve until the circuit split ends. The rare cert grant is Kalshi's only path to national sports market stability.
