Use BetMGM bonus code SIBONUS50 for a $1,500 First Bet on NBA & NHL Playoffs, MLB, and French Open action this May 25. | Sports Illustrated

Use the BetMGM bonus code SIBONUS50 to unlock a $1,500 First Bet offer ahead of a massive Monday, May 25 slate. From NHL and NBA playoff action to the French Open and MLB, there is no shortage of markets to explore. New users can also check out other sportsbook promos to compare what is available today.

How the BetMGM bonus code offer works for NHL playoffs, NBA, and French Open betting

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. You also receive $50 in MGM Rewards Points regardless of whether your bet wins or loses.

Here is a closer look at how the bonus bets are structured based on your wager amount:

• If your first wager is $50 or more and loses, you receive five bonus bets, each worth 20% of your original stake. For example, a $1,500 losing wager returns five $300 bonus bets totaling $1,500.
• If your first wager is less than $50 and loses, you receive one bonus bet equal to your stake.
• Bonus bets expire seven days after issuance and cannot be withdrawn directly. You must use them on a wager before accessing any potential payout.
• A minimum deposit of $10 is required to qualify.

To put this in context, say you place a $200 wager on the Montreal Canadiens to win Game 3 of the Eastern Conference Final against the Carolina Hurricanes on Monday night. If the Canadiens fall short at the Bell Centre, BetMGM returns your $200 in bonus bets. If they win, you collect your winnings outright. The same applies to any market, whether you are backing Jalen Brunson and the New York Knicks to complete the sweep over Cleveland, wagering on Jannik Sinner to advance at Roland Garros, or picking a side in any MLB matchup.

New users in Michigan, New Jersey, Pennsylvania, and West Virginia also have access to an alternate welcome offer. Use BetMGM promo code SIBONUS50 to place a $10 first wager, and if it wins, you receive $150 in bonus bets in addition to your winnings. The bonus is issued as three $50 bonus bets, each expiring seven days from issuance. Win or lose, you still receive $50 in MGM Rewards Points.

Those MGM Rewards Points are part of the BetMGM Rewards program, which lets you redeem points across several categories, including bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers for live events. You can learn more about the full program at the BetMGM Rewards page.
