Illinois Welcome Bonuses Side-by-Side
Welcome offers from every tracked operator licensed in Illinois. We sort by editorial rating because headline bonus values are not apples-to-apples (a $5-bet credit bonus and a $1,500 first-bet protection serve very different bankrolls). Pick by structure that fits your deposit, then by rating.

Bottom line for Illinois: FanDuel is our top pick at 4.8 / 5. Polished mobile app and the SGP+ builder, which lets bettors create same-game parlays faster and with better correlation pricing than at competitors. Different bettor profiles may prefer the category-specific winners above (sharp parlay players favor the SGP+ leader; small-stake casuals usually do better with whichever operator carries the lowest rollover requirement).

Illinois Sports Betting FAQ
Is online sports betting legal in Illinois?
Yes. Online sports betting launched in Illinois in Mar 2020. The market is regulated by the Illinois Gaming Board. Any sportsbook on this page is licensed by that regulator and accepts bets only from inside Illinois state lines (verified by geolocation).
How many sportsbooks operate in Illinois?
Illinois has 10 licensed online sportsbooks as of April 2026. We track 9 of them with active welcome bonuses on this page; the others are typically smaller regional operators or retail-only books.
What is the sports betting tax rate in Illinois?
Illinois taxes operators at 20-40% + $0.25-$0.50/bet. This is what the operator pays the state on revenue, not what bettors pay on winnings. Bettors pay federal income tax on net gambling winnings (24% withholding on large wins) plus any applicable Illinois state income tax.
Which sportsbook has the best welcome bonus in Illinois?
Headline dollar amounts vary across operators (Bet365's "$365 win-or-lose" is the largest single-figure offer; BetMGM's "$1,500 first bet" is the largest first-bet protection). Our editorial team ranks FanDuel the highest-rated overall in Illinois. Compare every offer in the table above to pick what fits your bankroll.
Can I use my Illinois sportsbook account in another state?
Yes for the major operators (DraftKings, FanDuel, BetMGM, Caesars, bet365). The same account works in any state where the operator is licensed; the app activates the correct state's odds, promotions, and payment methods based on your geolocation. You cannot bet from a state where the operator is not licensed regardless of your account residency.
What is the minimum age to bet on sports in Illinois?
21+ in Illinois. This matches the federal-default 21+ minimum used in most US sports betting states. You must verify your identity (full legal name, DOB, SSN) before placing any bets — this is a federal Know-Your-Customer requirement.
