BetMGM Bonus Code SIBONUS50: Get up to $1,500 Bonus Bets for MLB & WNBA Games on Friday
Friday, July 31 brings a loaded slate of baseball and basketball action, and new bettors can take advantage of a major welcome offer from BetMGM. The $1,500 back in bonus bets offer is available today with the BetMGM bonus code 'SIBONUS50'. You'll also earn sportsbook promos and $50 in MGM Rewards Points whether you win or lose your initial wager on the day's games.
How the BetMGM bonus code works for Friday's MLB and WNBA action
The BetMGM bonus code 'SIBONUS50' unlocks a straightforward welcome offer for new users. You'll deposit at least $10, place your first real money bet on any market, and if that bet loses, BetMGM returns your entire stake up to $1,500 in bonus bets. This gives you a substantial cushion to explore Friday's slate without the pressure of an immediate loss.
Here's how the bonus structure works: If you wager $1,500 on the Yankees-Cubs matchup at Wrigley Field and lose, you'll receive five $300 bonus bets (totaling $1,500). If you wager less than $50, you'll get one bonus bet equal to your stake. For example, a $100 first bet that loses would return $100 in bonus bets. These bonus bets expire seven days after issuance, so you'll have a full week to use them on the Red Sox-Dodgers game, Rangers-Astros rivalry matchup, or any other market available on the platform.
The offer includes several key terms to understand. Your initial deposit must be at least $10 to qualify. Bonus bets cannot be withdrawn as cash and must be used on additional wagers before you can access any potential payout. When you use a bonus bet, BetMGM does not return your stake if that bet loses. You'll also receive $50 in MGM Rewards Points regardless of whether your first bet wins or loses, which can be redeemed for bonus credits, Marriott Bonvoy Points, merchandise, or gametime vouchers. For more details on MGM Rewards Points, visit the official rewards page.

By using bonus code COVERS and depositing at least $10, players can place their first wager and receive bonus bets back—up to $1,500—if it loses. In contrast, the Bet $10, Get $150 offer is limited to MI, NJ, PA, and WV. With bonus code COVERSBONUS, new users who deposit $10 and place a $10 bet will earn $150 in bonus bets if that wager wins. Both deals are state-specific and only available to new registrants in eligible markets.
