New Jersey asks Supreme Court to settle who regulates Kalshi sports contracts
New Jersey's Attorney General filed a petition on September 2, 2026, asking the U.S. Supreme Court to hear a case on sports prediction markets. The state seeks clarity on whether federal law preempts state gambling regulations for event contracts on platforms like Kalshi. Lower courts had ruled in Kalshi's favor, allowing it to continue listing sports contracts.
The petition forces Kalshi into a high-stakes waiting game where every month of cert consideration risks another state filing. Nevada already stripped its federal shield, and Connecticut and Baltimore have parallel suits running. A Supreme Court grant would freeze state momentum and offer a single federal answer; a denial leaves Kalshi fighting fifty potential gaming commissions with Circuit precedent now running against it.
Traders hold positions whose legality shifts with state borders, not regulation. 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 uniform rules before its national sports market fragments entirely.
Becomes the first state to petition the Supreme Court over prediction-market regulation, joining a state-by-state assault that has already stripped Kalshi of its federal shield in Nevada and spawned parallel suits in Connecticut and Baltimore.
