Illinois Sports Betting Guide: What's Legal for Online Gambling in 2026?

Illinois sports betting is fully legal, online and at retail, with more than a dozen licensed sportsbook operators accepting wagers across the state. Illinois' online gambling market is robust and well-regulated.

Illinois Sports Betting: Legal Status, Rules & Licensed Operators

Illinois legalized sports betting in June 2019, and the market has since grown into one of the top revenue-generating markets in the U.S. The state generated a record $15.5 billion in total handle in 2025, second only to New York,  cementing Illinois as the largest sports betting market in the Midwest. Whether you're backing the Chicago Bears, the Chicago Bulls, or a Big Ten matchup, Illinois' legal wagering infrastructure is among the most developed in the country.

Status Overview

• Legal Status: ✅ Legal (Online + Retail).
• Launch Date: June 18, 2020 (online).
• Regulator: Illinois Gaming Board (IGB), the state's primary regulatory and law enforcement agency overseeing casino gambling, video gaming, and sports wagering.
• Tax Rate: Progressive rate (20% to 40% based on adjusted gross revenue). The bottom rate applies to the first $30 million in AGR; the top 40% rate kicks in above $200 million. An additional 2% applies to AGR from wagers placed within Cook County. Starting in 2026, Chicago imposed a 10.25% tax on AGR from all sports bets placed in the city.

Prediction Markets in Illinois: A Contested Legal Battleground

Prediction markets have become a flashpoint in Illinois online gambling regulation. While these platforms operate under federal oversight, the Illinois Gaming Board (IGB) actively opposes them, issuing cease-and-desist orders in April 2025 and introducing legislation in 2026 to ban sports-related wagering. The core dispute is a jurisdictional one: federal authority versus state gambling law.

Legal Status of Prediction Markets in Illinois

• Status: ⚠️ Contested / High Risk.
• The Conflict:
• Federal View: Platforms like Kalshi and Robinhood operate as CFTC-regulated derivatives exchanges, arguing federal preemption over state gambling laws.
• State View: In April 2025, the IGB issued cease-and-desist orders to Kalshi, Robinhood, and Crypto.com, declaring their "event contracts" illegal sports wagering because they lack state-issued sports betting licenses.
• Outcome: As of 2026, litigation is ongoing. Kalshi continues to operate nationally (citing federal authority), but Illinois users face potential access restrictions or future shutdowns depending on court rulings.

Major Prediction Market Platforms: What Illinois Bettors Need to Know

Compliance Warning: Illinois regulators consider these platforms illegal without a sports betting license. Proceed with caution.

Kalshi – Federally Regulated

Status: Live nationally, but under an IGB cease-and-desist order.

What it is: A CFTC-regulated exchange for "Yes/No" event contracts covering elections, economic indicators, weather, and sports outcomes.

Illinois Stance: The IGB contends that offering sports-related contracts constitutes unlicensed sports wagering under state law.

Robinhood – Derivatives Trading

Status: Live nationally, but under an IGB cease-and-desist order.

What it is: Offers event contracts via Kalshi integration and election markets.

Illinois Stance: Targeted by state regulators for offering gambling-like products without a state license.

Polymarket – Over 100 Contracts to Trade

Status: Live in Illinois with over 100 contracts available to trade. The platform's regulatory standing in Illinois is unresolved.

What it is: Offers a wide variety of markets, including sports, politics, pop culture, and more.

Illinois Stance: The state is actively looking to regulate the market and ban sports-related contracts, impacting a significant portion of Polymarket’s business.

Daily Fantasy Sports in Illinois: Explicitly Legal, But Evolving

Daily Fantasy Sports (DFS) is fully legal in Illinois following a decisive 2020 Illinois Supreme Court ruling that classified DFS as a game of skill, exempting it from the state's gambling laws. That ruling settled years of legal ambiguity and gave operators a clear green light, though the landscape has since grown more complex, particularly around pick-'em-style contests that blur the line between DFS and sports wagering.

DFS Legal Framework and Regulatory Status

• Status: ✅ Legal (peer-to-peer DFS).
• Key Ruling: Dew-Becker v. Wu (April 2020), the Illinois Supreme Court ruled that DFS contests are games of skill, ending years of legal ambiguity. The court held that participants in online fantasy sports contests were not engaged in "gambling" because winning is based on skill.
• Current Legislation: In 2025, lawmakers introduced SB 1224, the Fantasy Sports Consumer Protection Act, to formally regulate all DFS contests, including both peer-to-peer and against-the-house formats, under the IGB. The bill, introduced by State Senator Lakesia Collins, would authorize the IGB to license and regulate fantasy contest operators, set tax rates, and establish consumer protections. The bill's scope covers DFS broadly; its specific application to pick 'em-style games remains a subject of active legislative debate. While picked up in 2026, the bill has floundered in committee.

The regulatory environment for DFS in Illinois is in flux. In early 2025, the Illinois Attorney General accused PrizePicks of offering unlicensed sports betting in the state, and the IGB issued a cease-and-desist letter to the operator. PrizePicks subsequently shifted to a peer-to-peer model for Illinois users, discontinuing its player-vs-house contests in the state. This crackdown signals that while traditional salary-cap DFS remains on solid legal footing, against-the-house pick'em products face growing scrutiny from Illinois regulators.

Major DFS Apps Available to Illinois Players

• DraftKings & FanDuel: Traditional salary-cap fantasy. The gold standard for peer-to-peer DFS competition.
• PrizePicks: Now operating in a peer-to-peer model in Illinois following the IGB's cease-and-desist action against its house-banked contests.
• Underdog Fantasy: Best ball drafts and pick'em contests. Legal status of house-banked formats subject to ongoing regulatory review.
• Betr Picks: Micro-betting focus with a growing Illinois user base.

Online Casinos in Illinois: Not Yet Legal, But Legislation Is Moving

Real-money online casinos, also known as iGaming, are currently illegal in Illinois. However, the state is widely considered one of the most likely candidates to legalize regulated online casino gambling in the near term, driven by a significant budget shortfall and growing legislative momentum.

• Current Status: ❌ Illegal.
• Legislative Push:
• SB 4879 was filed in 2026 and seeks to create the Internet Gambling Act to legalize online casinos. If passed, only three licenses would be issued. Unfortunately, the bill has not moved since March and looks unlikely to pass in 2026. .
• Governor Support: Gov. JB Pritzker called iGaming "worthy of consideration" to address past state budget  deficits. With a projected 2.2 billion deficit for FY 2027, iGaming could become an attractive option to help fill the gap.
• Proposal Details: A proposed tax rate of 15% to 25%; a $250,000 license fee; up to three online "skins" per casino license.

Timeline: . Analysts view Illinois as a top candidate for iGaming legalization by 2027–2028, with the state's fiscal pressures providing a powerful incentive for lawmakers to act.

Sweepstakes Casinos in Illinois: The Legal Casino Alternative

With real-money iGaming not yet live in Illinois, sweepstakes casinos are the primary legal option for casino-style gaming in the state. These platforms operate under a fundamentally different model than traditional online casinos, which is why they remain legal in Illinois and many other U.S. states, including Wisconsin, Missouri, and Kentucky.
