Since the legalisation of online sports betting in Illinois in 2020, the top sportsbooks in the state have been offering enticing welcome offers for new users. FanDuel, once a leading force in daily fantasy sports, expanded into sports betting and has become a major player in the space. New customers can receive up to $1,500 in bonus bets if their first bet loses, which can be matched in bonus bets. BetMGM Illinois launched in 2022, offering some of the most expansive betting markets available in the industry. Caesars Sportsbook is one of the popular sportsbook in the game, while Fanatics Sportsbook does not offer a website and all sports betting is done through its mobile app. DraftKings Sportsbook's welcome bonus includes $200 in bonus betting after placing an initial wager of at least $10.
