Illinois Sports Betting: Is It Legal, And How Do You Bet?
If you live in Illinois and you want to bet on the Bears, the Bulls, the Cubs, the White Sox, or the Blackhawks from your phone, you can. Online sports betting has been legal in Illinois since June 2020, and the state has grown into one of the biggest and most competitive markets in the country. This guide covers the part the sportsbook ads skip: whether it is actually legal (yes), who runs it, the one rule about college betting that trips people up, and how to make sure you are not handing the book free money on every bet.
Is Sports Betting Legal In Illinois?
Yes. Online sports betting is legal in Illinois and has been since June 2020, when the state's regulated market went live. Betting is overseen by the Illinois Gaming Board (IGB), the agency that licenses the state's online sportsbooks and enforces the rules they operate under. Illinois launched its regulated market in the years after the federal ban on sports betting fell, and it has since built out a deep field of licensed operators.
A few basics that apply to every legal Illinois sportsbook:
- You Must Be 21 Or Older to place a bet.
- You Must Be Physically Inside Illinois when you place it. Apps use geolocation to confirm you are in-state, so trying to bet from across the border in Indiana or Wisconsin on an Illinois account will not work.
- You Do Not Have To Be An Illinois Resident. A visitor who is 21+ and standing in the state can bet.
Because Illinois has been live since 2020 with a full field of operators, it has matured into one of the deepest, most competitive markets in the country, and that matters for one practical reason: with so many books chasing the same bettors, it pays to compare prices across them before you bet. That habit is where careful bettors find value, and we will come back to it. (Betting laws vary state to state; see our sports betting by state guides for the rules where you live.)
Which Sportsbooks Operate In Illinois?
Illinois is home to roughly 10 licensed online operators, including the major national sportsbooks you know from TV. The books below are the big-name examples, not the full list, because the IGB licenses additional operators, and you can check its current list before you sign up:
The OddsShopper Odds Screen.
| Sportsbook | Status in Illinois |
|---|
| DraftKings | Live |
| FanDuel | Live |
| BetMGM | Live |
| Caesars Sportsbook | Live |
| Bet365 | Live |
| Fanatics Sportsbook | Live |
| BetRivers | Live |
Those are among the biggest names in the state, and several more licensed operators round out the field of roughly ten. For a bettor, having that many books to choose from is a good thing. Not because you should bet more, but because more books means more prices to compare on the same wager. Signing up at two or three of them, rather than living inside one app, is one of the easiest edges available to an Illinois bettor.
Key takeaway: The same bet is priced differently at each book. One of the most practical habits available to you is simple: sign up at a few of them, compare the price before you bet, and take the best number.
Illinois Betting Rules And Restrictions
Illinois offers a broad legal betting market, with one restriction that catches people off guard, so it is worth knowing before you go looking for a specific bet:
- No Betting On In-State College Games Or College Player Props. Illinois does not allow wagering on in-state college games or player props on individual college athletes, so a home-state college matchup involving an Illinois school is a market fans may not find. You can still bet the pros freely, and pro player props are unaffected. Rules can change and the exact scope varies, so confirm the current college-betting rule with your sportsbook or the IGB before you place a college bet.
- 21-And-Up, In-State Only. You have to be at least 21 and physically located in the state to bet, and the apps confirm it through geolocation every time you log a wager.
- Bet Through Licensed, Regulated Apps. Sticking to IGB-licensed operators gives you regulated books with state oversight. Offshore and unregulated sites are not legal operators and carry real risk to your money.
Key takeaway: The college rule is the one that catches Illinois bettors out. In-state college games and college player props are off the board, so confirm what you can bet with the IGB, while pro markets are broadly available, subject to each sportsbook's rules.
Everything else you would expect (moneylines, spreads, totals, parlays, live/in-game betting, and pro player props) is on the board at the licensed books. Available markets can still vary by sportsbook, so it is always worth confirming the current rules for a given bet before you go looking for it.
How OddsShopper Helps Illinois Bettors
This is where the "best Illinois betting apps" lists stop short. Once you have accounts at a few of the Illinois books, the question stops being which app and becomes which app has the best number on the bet I want right now. That answer changes bet to bet, and no single sportsbook is the best price on everything.
Line shopping is the habit of checking every book's price before you bet and taking the best one. It sounds small, but it is one of the most practical edges available to bettors, and it costs you nothing. Living inside a single app leaves money on the table whenever another book has a better price.
A Quick Example: Line Shopping An Illinois Game
Say one Illinois book has the Cubs at -150 and another has the same Cubs moneyline at -140. It is the identical bet, but at -150 you risk $150 to win $100, while at -140 you risk $140 to win $100. Once you have decided to make that bet, the -140 is the price to take. Do that across a season and it adds up, purely from taking better prices on the bets you were already making. That is the whole game: same wager, better number.
This is exactly what OddsShopper is built to do, automatically, across the Illinois market:
| Tool | What it does for an Illinois bettor |
|---|
| Odds Screen (Line Shopping) | Tracks 100+ sportsbooks across covered markets in real time; filter to the books available to you in Illinois and take the best price on any market, instead of eyeballing two apps. |
| No-Vig / Fair-Odds Pricing | Strips the book's built-in margin (the "vig") to show the true price of a bet, so you can see which book is actually offering value. |
| +EV Screen | Ranks bets by expected ROI (xROI) and expected win %, flagging the wagers priced in your favor relative to the sharp market. |
| Arbitrage Tool | Designed to surface potential arbitrage opportunities when prices differ across books; lines can move, limits apply, execution risk remains, and losses are still possible, so it is never risk-free (see our arbitrage guide). |
| Hold Display | Shows how much margin a book baked into a market before you bet it. |
The important point for an Illinois reader: these tools work wherever the books post lines. They are not tied to a state. Because Illinois already has a deep field of operators pricing the same games, there is plenty of price to compare, which is exactly the environment where line shopping and +EV pay off most.
What is "+EV"? A positive-expected-value (+EV) bet is one where the price you are getting is better than the true odds of the outcome. You will not win every one, but bet enough of them at the right prices and the math works in your favor over time. It is the same principle as line shopping, scaled up: take the number that is better than it should be. More on that in our +EV explainer.
One note tied to Illinois's rules above: with in-state college games and college player props off the board, point these tools at the markets you can bet: pro game lines, totals, pro props, and parlays built from them.
