Federal judge blocks Illinois from enforcing law against Kalshi and Coinbase
U.S. District Judge Martha Pacold ruled that Illinois cannot enforce a state law regulating Kalshi's predictive betting products. The decision prevents the state from applying its regulatory framework to the prediction market platform. Coinbase was also covered by the ruling. Pacold wrote that the statute does not federalize all gambling or even all sports gambling. The ruling came down Friday, Oct. 2. The case involves state-level regulatory action targeting prediction market and crypto exchange operations.
Kalshi keeps its Illinois preemption shield, but that shield is already gone in Ohio and Tennessee. The Sixth Circuit rulings there and the NFL's Supreme Court brief give other state attorneys general a ready template to copy. Each new state suit multiplies defense costs and fragments national markets into geofenced patches where contracts trade in some states but not others.
Kalshi and Polymarket must now fund parallel legal spend across multiple jurisdictions while waiting for federal rulemaking that moves slower than courtroom clocks. The first operator to lose another major state case sets the compliance bar every competitor races to clear.
Kalshi's Illinois win joins its earlier federal preemption victory in Illinois and the Sixth Circuit's Ohio and Tennessee losses in deepening a circuit split that may reach the Supreme Court, as the NFL urges justices to let states regulate prediction markets as gambling.
