## Full section analysis

Illinois' sports-wagering and fantasy-contest framework continues to operate, but a federal court ruling has partially suspended its application to prediction-market exchange contracts. The Illinois Sports Wagering Act and SB 3019 together establish the licensing architecture for both traditional exchange wagers and fantasy contests, with the Illinois Gaming Board as supervisory authority. On 2 October 2026, a federal court held that Illinois' sports-wagering licensing and criminal provisions, as applied to CFTC-regulated prediction-market operators such as Kalshi and Coinbase, are likely preempted by the Commodity Exchange Act, and preliminarily enjoined their enforcement. Separately, the IGB is advancing player-protection rulemaking, with First Notice proposed amendments to self-exclusion and marketing rules published 2 October 2026. Both developments remain unresolved.
