Use the BetMGM bonus code SIBONUS50 to claim a $1,500 First Bet offer in time for Tuesday's loaded sports slate. From Game 5 of the Western Conference Finals to the French Open, there is no shortage of action to target with your first wager. Check out all available sportsbook promos before placing your bet on May 26.

How the BetMGM bonus code works for NBA playoffs, French Open, and more

The BetMGM bonus code SIBONUS50 unlocks a First Bet offer worth up to $1,500 for new users. Place your first real money wager on any available market, and if it loses, BetMGM will return your stake in bonus bets. With Game 5 of the Spurs vs. Thunder Western Conference Finals on the board, along with the Golden Knights looking to sweep the Avalanche, there are plenty of compelling spots to put your first bet to work.

Here is a closer look at how the offer breaks down:

  • New users must register with BetMGM promo code SIBONUS50 and make a minimum $10 deposit.
  • Place a real money wager on any sport or market, including NBA playoffs, NHL playoffs, French Open, or MLB.
  • If your first bet loses, you receive your stake back in bonus bets, up to $1,500.
  • Wagers above $50 are returned as five bonus bets, each worth 20% of your qualifying stake. For example, a $1,500 losing wager returns five $300 bonus bets.
  • Wagers of $50 or less are returned as a single bonus bet.
  • Bonus bets expire seven days after issuance and cannot be withdrawn directly.
  • Win or lose, you also receive $50 in MGM Rewards Points just for participating.

Say you bet $200 on Victor Wembanyama to lead the Spurs to a Game 5 win in Oklahoma City and the bet loses. BetMGM would return that $200 as bonus bets, giving you another shot at the board. If your bet wins, you collect your winnings immediately and still earn the $50 in MGM Rewards Points. Those points are part of the BetMGM Rewards program, which lets you redeem points for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the full rewards program at the BetMGM Rewards page.

New users in Michigan, New Jersey, Pennsylvania, and West Virginia can also opt for the Bet $10, Get $150 offer using the same BetMGM Sportsbook promo code SIBONUS50. Place a $10 wager and if it wins, you receive $150 in bonus bets issued as three $50 bonus bets, plus $50 in MGM Rewards Points regardless of outcome.

This BetMGM promotion is available to first-time users in the following states: AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MS, NC, NJ, OH, PA, TN, VA, WV, WY. It is not available in NV, NY, or Ontario, Canada.
