Since the legalisation of online sports betting in Illinois became legal in 2020, the top sportsbooks in the state are offering enticing welcome offers for new users. FanDuel Sportsbook, a leading force in daily fantasy sports, has expanded into sports betting and has become a significant player in the space. BetMGM Illinois, FanDul, Fanatics Sportsbook and BetMEG Sportsbook are among the top three sportsbooks currently available in Illinois. The CBSSPORTS250BM, for example, gives new users a first bet match up to $250 as a bonus bet, win or lose, and if their first bet loses, the money will be matched in bonus bets. Fanatics does not offer a website and all sports betting is done through its mobile app. The COOF offers up to 50% of its bets can be purchased through FanCash. The BOP250 offers up for $250 in FanCash, which expires seven days after the first bet is placed and expires if not used, and unused Bonus Bets can be removed from the account holder's account within 30 days. Other top sportsbook offers competitive bonuses at both welcome and existing user levels and includes bets from Caesars Sportsbook.
