Illinois operates one of the country's largest legal sports betting markets, with ten licensed online sportsbooks operating under IGB oversight. Beyond that, the regulatory picture is hostile on every front. In February 2026, the IGB issued 65 cease-and-desist orders — the most sweeping enforcement action against the sweepstakes casino industry in any state — targeting Stake.us, Chumba Casino, and 63 others on the basis that they constitute illegal online casinos under Illinois criminal law. On prediction markets, the IGB published a formal memorandum in October 2025 declaring them illegal gambling, issued cease-and-desist letters to Kalshi and Polymarket, and prompted a federal response: the CFTC and DOJ jointly sued Illinois on April 2, 2026, seeking a permanent injunction on CEA preemption grounds. Governor Pritzker followed with an executive order on April 21, 2026, banning state employees from trading on prediction markets.
Illinois Gambling Law Breakdown
Illinois takes a permission-based approach to gambling: all gambling is illegal unless explicitly authorised by statute. The Illinois Gaming Board is the primary licensing and enforcement authority. The key statutes are in Title 720 (criminal code), Title 230 (gaming acts), and have been supplemented by the IGB's own memoranda and executive action in 2025–2026.
Makes it unlawful to knowingly establish, maintain, or operate an internet site that permits a person to play a game of chance or skill for money or other thing of value, or to make a wager upon the result of any sport, game, contest, political nomination, appointment, or election via the internet, without an IGB-issued licence. This is the primary statute cited in every IGB cease-and-desist letter issued against sweepstakes casinos and prediction markets. There are no exceptions for sweepstakes-model operations under this statute — the IGB's position is that prize-redeemable gameplay constitutes "other thing of value."
Legal gambling in Illinois is restricted to a narrow set of licensed categories: riverboat casinos, land-based casinos holding an owner's licence, racetracks with organisation gaming licences, sportsbooks licensed under the Sports Wagering Act, and establishments licensed under the Video Gaming Act. The IGB cites this statute in every enforcement action to establish that no other form of gambling, including sweepstakes prize redemption and prediction market contracts, is authorised under Illinois law. The Illinois Prizes and Gifts Act (815 ILCS 525/1 et seq.) provides no exemption for sweepstakes operations — a point the IGB has made explicit in its C&D letters.
Signed into law October 2019, with the first legal bets placed March 9, 2020. Defines "sports wagering" broadly to include single-game bets, parlays, proposition bets, in-game wagering, and exchange wagering, by any system including internet and mobile devices. Licensed casinos, racetracks, and professional sports venues may hold sportsbook licences. The Sports Wagering Act is also the basis for the IGB's argument that prediction market sports-event contracts constitute unlicensed sports wagering — since the Act covers "any system or method of wagering" on sports events. Bets on in-state college teams (e.g. University of Illinois) are not permitted. Online casino gaming is explicitly outside the scope of this Act.
The IGB issued a formal memorandum to all licensees, applicants, and stakeholders on October 23, 2025, confirming its position that "prediction markets constitute gambling activity under Illinois law." The memorandum cited the J&J Ventures Gaming, LLC v. Wild, Inc. (2016 IL 1198760) precedent that there is no right to engage in or profit from gambling through contract. It warned that IGB licensees who associate with or facilitate prediction market activity in violation of gaming laws may have their own Illinois suitability for licensure impacted — a significant deterrent for established operators. The memorandum preceded the formal C&D letters issued to Kalshi (April 2025) and Polymarket (January 2026).
Governor Pritzker issued Executive Order 2026-04 on April 21, 2026, prohibiting all Illinois state employees from using nonpublic government information to participate in or assist others in participating in prediction markets or event contracts of any kind. The order frames prediction markets as lacking "meaningful regulatory oversight" and cites the risk of insider trading on governmental actions, elections, and policy decisions. While the order applies to state employees only and does not directly restrict player access, it reinforces the state's formal hostility toward prediction markets and signals that any federal preemption victory would face continued state-level resistance.
Sweepstakes Casinos in Illinois
The Illinois Gaming Board issued cease-and-desist orders to 65 sweepstakes and online casino operators on February 5, 2026, in the most sweeping state-level enforcement action the industry has faced. Both Stake.us and Chumba Casino were named. Stake.us exited Illinois effective May 19, 2026. Chumba Casino received a C&D but as of June 2026 continues to operate in Illinois without implementing geoblocking — a situation of documented non-compliance that could escalate. No profiled platform is confirmed available with full redemption access in a compliant status.
The Illinois Gaming Board, which issued 65 cease-and-desist letters to sweepstakes and online casino operators in February 2026 — the largest such enforcement action in any US state.
Licensed Operators in Illinois
Online sports betting has been legal in Illinois since March 2020 under the Sports Wagering Act (230 ILCS 45/25-10), with ten licensed operators currently active. Online casino gaming (iGaming) is not legal in Illinois. HB 4797, filed February 2026 by Rep. Edgar González, would create the Internet Gaming Act to allow the IGB to license iGaming operators — however, the bill has stalled in committee with no hearings or votes scheduled as of June 2026. No Wager Layer-profiled operator currently holds an Illinois online casino licence, as no iGaming framework exists. Caesars holds an Illinois sportsbook licence but is profiled here for its online casino product, which is not available in this state.
Prediction Markets in Illinois
Illinois has been at the centre of the federal-state prediction market conflict since April 2025, when the IGB issued its first cease-and-desist letters to Kalshi and Crypto.com. In October 2025, the IGB published a formal memorandum declaring prediction markets constitute illegal gambling under state law. The CFTC and DOJ responded by filing a joint federal lawsuit against Illinois on April 2, 2026 (Case 1:26-cv-03659, N.D. Illinois), seeking a permanent injunction on Commodity Exchange Act preemption grounds. Governor Pritzker reinforced the state's position with Executive Order 2026-04 on April 21, 2026. Kalshi has suspended services to Illinois residents pending the outcome of federal proceedings.
Active Legislation & Enforcement Actions
Illinois has both active legislative proposals and live federal litigation affecting the online gambling landscape. The federal preemption case is the most consequential active proceeding. On the legislative side, an iGaming bill has been filed but has not progressed.
The CFTC and DOJ filed a joint federal lawsuit against Illinois, naming Governor Pritzker, AG Kwame Raoul, and five IGB officials as defendants. This is described by the CFTC as the first direct federal preemption lawsuit brought against a state over event contract markets. The complaint argues that the Commodity Exchange Act grants the CFTC exclusive jurisdiction over swaps and futures traded on federally licensed designated contract markets, preempting Illinois's application of state gambling laws. Relief sought: a permanent injunction barring Illinois from enforcing three named gambling statutes against CFTC-licensed DCMs, and a declaration that those statutes are unconstitutional as applied. The DOJ's participation signals that federal enforcement interest extends beyond the CFTC. The CFTC filed simultaneous suits against Arizona and Connecticut on the same date.
The IGB issued 65 C&D letters to sweepstakes casino and online casino operators on February 5, 2026 — the largest single enforcement sweep against the sweepstakes casino industry by any US state. Letters were sent in coordination with the Illinois AG's office and copied to the Illinois State Police Statewide Gaming Command. Named operators include Stake.us, Chumba Casino (VGW), LuckyLand Slots (VGW), Global Poker (VGW), High 5 Casino, Pulsz, Fliff, Modo, and others. The IGB cited 720 ILCS 5/28-1(a)(12) and stated the Illinois Prizes and Gifts Act (815 ILCS 525/1 et seq.) provides no exception. Compliance has been highly uneven: as of June 2026, only around six operators have formally geoblocked Illinois, with Stake.us (exit May 19, 2026) the most prominent departure. The majority of named operators, including Chumba Casino, continue to serve Illinois players.
HB 4797 would create the Internet Gaming Act, authorising the IGB to issue iGaming licences to operators, with each licence holder permitted to offer up to three individually branded online casino products. The bill proposes a 25% gross gaming revenue tax. This is González's second consecutive year filing essentially the same bill — his 2025 version did not advance beyond the committee stage. As of June 2026, HB 4797 has made no progress, with no committee hearings or votes scheduled. Illinois's high sports wagering tax rate (up to 40% under the bracket system introduced October 2024) has complicated the state's appetite for further gaming expansion amid concerns about operator viability.
Governor Pritzker signed Executive Order 2026-04 on April 21, 2026, prohibiting all Illinois state employees from using nonpublic government information to participate in, or assist others in participating in, prediction markets or event contracts of any kind. The order cites insider trading risk, the absence of meaningful regulatory oversight on prediction platforms, and the existing state law precedent that there is no right to profit from gambling through contract. The order applies to state employees only — it does not directly restrict Illinois residents from accessing prediction market platforms. However, it signals that the state intends to maintain its opposition regardless of the federal litigation outcome.
Player Guidance — Illinois
Illinois residents have access to a competitive licensed sportsbook market, but the state's enforcement posture on sweepstakes casinos and prediction markets is among the most aggressive in the country. The IGB's 65 C&D sweep and the CFTC's federal counter-suit make this one of the most legally dynamic states to monitor in 2026.
Illinois operates one of the country's largest licensed sports betting markets. Ten online sportsbook apps are IGB-licensed and fully operational. Verify your chosen operator holds a current IGB licence at igb.illinois.gov before depositing. These platforms carry full state regulatory protections including dispute resolution and responsible gambling tools.
Stake.us placed Illinois accounts into Redeem Only mode effective May 19, 2026, and will fully close Illinois access. VPN use violates Stake.us terms of service and will result in account suspension and forfeiture of any Sweeps Coin balance. Players with existing SC balances should redeem through official channels before the platform fully restricts access.
Chumba Casino received an IGB C&D on February 5, 2026, but continues to operate in Illinois as of June 2026. While the IGB's enforcement targets operators rather than players, access may be removed without notice if the IGB escalates to civil or criminal proceedings. Players with SC balances on Chumba should monitor platform communications. This situation is distinct from a statutory ban — no Illinois law has passed specifically targeting sweepstakes players.
Kalshi has suspended services to Illinois residents. The IGB's October 2025 memorandum formally declared prediction markets constitute illegal gambling, and the CFTC's April 2026 federal suit is the primary legal battleground. Until the federal proceedings resolve, Illinois residents cannot access Kalshi or other prediction market platforms through legal channels. The outcome of Case 1:26-cv-03659 will be determinative.
A ruling in the CFTC's favour in Case 1:26-cv-03659 would block Illinois from enforcing its gambling statutes against CFTC-licensed prediction market exchanges, potentially restoring Kalshi access. A ruling against would confirm state authority to restrict these platforms. This page will be updated when a ruling is issued. See Wager Layer's Kalshi Circuit Split analysis for the broader federal preemption picture.
