Is Sports Betting Legal in Illinois? Your Complete 2026 Guide

The short answer is a resounding yes. Sports betting is fully legal in Illinois, both online and in person.

Since Governor J.B. Pritzker signed the Illinois Sports Wagering Act into law in 2019—and the first legal wagers were placed in early 2020—the Prairie State has grown into one of the most lucrative sports betting markets in the United States. However, the market has undergone some massive shifts over the last few years, from the permanent removal of in-person registration requirements to some controversial new tax structures introduced in 2024 and 2025.

If you’re wondering how the landscape looks today, here is your comprehensive, up-to-date guide to the real facts about sports betting in Illinois for 2026.

📝 Illinois Sports Betting: Quick Facts

The Current Rules of the Game

While the gates are wide open for sports bettors in Illinois, the state operates under a highly specific regulatory framework enforced by the Illinois Gaming Board (IGB). Here is what you need to know before placing a wager:

• Age and Location: You must be at least 21 years old to bet. You do not need to be an Illinois resident, but you must be physically located within state lines when placing a wager. All legal sportsbooks use strict geolocation tracking software to verify this.
• No In-Person Registration: In the early days of Illinois sports betting, users were forced to visit a physical casino to activate their mobile betting accounts. That barrier was permanently removed in March 2022. Today, you can download an app, verify your identity, deposit funds, and bet entirely from your smartphone.
• The “In-State College” Quirk: This is one of the most important rules for local fans. As of 2026, you cannot bet on in-state collegiate teams (like the Illinois Fighting Illini or Northwestern Wildcats) via online apps. If you want to place a wager on an Illinois college team, you are legally required to do so in person at a licensed retail sportsbook.

2025–2026 Updates: The Tax Hike and Surcharges

If you’re reading up on Illinois sports betting, you can’t ignore the recent legislative drama. In 2024, the state ditched its flat 15% tax rate on sportsbook revenues in favor of a graduated scale ranging from 20% up to 40% for the top earners.

The Per-Wager Tax Controversy (2025/2026) In mid-2025, the Illinois General Assembly passed an aggressive new budget that slapped heavy operators (those taking over 20 million bets) with an additional tax: $0.25 per wager for the first 20 million wagers, and $0.50 for every bet after that. Because of this intense tax burden, major operators like FanDuel announced consumer-facing transaction fees in Illinois to offset the costs. However, pushback has been severe. In early 2026, lawmakers introduced HB 4171 in an effort to repeal some of these heavy city and per-wager taxes to prevent the Sports Betting Alliance (representing major sportsbooks) from pulling their apps out of the state altogether.

What this means for you: When using major apps in Illinois this year, keep an eye on your bet slips for any newly instituted transaction fees or slight changes in odds pricing as sportsbooks try to navigate the state’s aggressive tax climate.

Top Legal Sportsbooks in Illinois

Despite the regulatory tug-of-war, Illinois remains a massive market with a highly competitive roster of top-tier platforms. The leading licensed sportsbooks currently operating include:

1. BetRivers: The first online sportsbook to launch in the state (June 2020), BetRivers remains a hometown favorite with excellent local promotions.
2. DraftKings: Boasting an incredibly deep menu of prop bets and a slick interface, DraftKings consistently fights for the number one market share spot in the state.
3. FanDuel: Known for inventing the Same Game Parlay (SGP), FanDuel offers arguably the most user-friendly app, though bettors should watch for their recently implemented state tax surcharges.
4. Caesars Sportsbook: Features one of the best rewards programs in the industry, allowing bettors to earn points toward physical casino stays and dining.
5. BetMGM: A premium app with excellent live-betting features and competitive daily odds boosts.

How to Get Started

If you are 21 or older and inside state lines, getting started is incredibly straightforward:

1. Choose a Licensed Operator: Pick one of the IGB-approved sportsbooks listed above. Avoid offshore, unregulated websites, as they offer no legal consumer protection.
2. Download the App: Find the app in the iOS App Store or Google Play Store.
3. Register and Verify: Provide your basic information (name, address, date of birth, and the last four digits of your SSN) so the sportsbook can verify your identity and age.
4. Deposit Funds: Use a secure method like PayPal, bank transfer, or debit card to load your account.
5. Place Your Bets: Browse the markets, build your bet slip, and enjoy the games!

Most Popular Sports to Bet on in Illinois

Illinois is home to one of the most passionate and deeply rooted sports cultures in the country, largely driven by the massive Chicago market. Unsurprisingly, this rabid fandom translates directly into betting handle. While almost every global sport is available on legal apps, a few key markets dominate the Illinois bet slips.

🏈 Football (NFL & College)

Football reigns supreme in the United States, and Illinois is no exception. The Chicago Bears are the primary driver of betting action during the fall and winter. From Sunday moneyline bets to Super Bowl futures and weekly player props (like Caleb Williams’ passing yards), the NFL pulls in the largest share of the state’s betting revenue.

College Football is also massive, but bettors must remember the “in-state” caveat. While you can freely bet on the Big Ten powerhouses like Ohio State or Michigan from your phone, wagers on the Illinois Fighting Illini or Northwestern Wildcats are strictly prohibited on mobile apps and must be placed in person at a retail sportsbook.

🏀 Basketball (NBA & NCAA)

Basketball holds a special place in the Prairie State’s heart. Historically, March Madness consistently sets records for betting handle in Illinois.

• The NBA: The Chicago Bulls heavily dictate the local betting trends, with daily spread bets, totals, and Same Game Parlays (SGPs) keeping the action constant throughout the long 82-game season.
• College Basketball: Illinois is a college hoops hotbed. The NCAA Tournament alone routinely generates hundreds of millions of dollars in handle for the state. However, just like college football, betting on in-state programs (like Loyola Chicago or Illinois) is banned online to prevent any potential integrity issues with local athletes.

⚾ Baseball (MLB)

During the summer months, when the NFL and NBA are in their offseasons, Major League Baseball keeps the Illinois sports betting market thriving. The state is uniquely positioned with a fierce cross-town rivalry:

• The Chicago Cubs (North Side)
• The Chicago White Sox (South Side)

With 162 games per team, baseball offers unparalleled daily volume. MLB betting is heavily focused on moneylines, run lines, and incredibly popular daily props like “First Inning (NRFI/YRFI)” bets and pitcher strikeout totals.

🏒 Hockey (NHL)

The Chicago Blackhawks carry the torch for hockey bettors in the state. While the NHL doesn’t command the same raw volume as football or basketball, it maintains a dedicated betting audience. The fast-paced nature of hockey makes it particularly popular for live (in-game) betting, where odds shift rapidly from period to period based on the action on the ice.

⚽ Soccer & Niche Sports

As the legal market has matured into 2026, bettors are diversifying their portfolios. Soccer betting has seen a steady rise, fueled by the local Chicago Fire (MLS), the Chicago Red Stars (NWSL), and massive international leagues like the English Premier League and Champions League.

Additionally, individual sports like PGA Golf, Tennis, and UFC/MMA provide massive, event-driven spikes in betting handle during major tournaments and pay-per-view weekend cards.
