Woofun AI reports that Kalshi has filed a lawsuit against the state of Illinois and Governor JB Pritzker in the U.S. District Court for the Northern District of Illinois. The complaint opposes SB3019, which imposes a 0.2% fee on digital asset transactions and mandates state licenses for predictive market platforms, arguing these measures cause "irreparable damage" upon July 1 implementation.

Kalshi contends that the legislation violates federal law because derivative contracts fall under federal regulatory jurisdiction. The company asserts that complying with state mandates would breach CFTC requirements for regulatory uniformity and result in significant financial losses.

Additionally, Kalshi argues that implementing costly technical restrictions to block Illinois access is uneconomical, particularly if the legal challenge succeeds.
