BetMGM Bonus Code SIBONUS50: Get $1,500 Back in Bonus Bets if Your First Bet Loses on MLB & WNBA
Thursday, July 30 brings a balanced slate of baseball and basketball action, and new bettors can capitalize on the moment with a strong welcome offer. The $1,500 back in bonus bets available through BetMGM bonus code SIBONUS50 gives you a substantial cushion for your first wager on any of today's games. You'll also earn $50 in MGM Rewards Points regardless of the outcome. Check out our sportsbook promos page for more welcome offers across the industry.
How the BetMGM bonus code works for Thursday's MLB and WNBA games
The BetMGM bonus code SIBONUS50 unlocks a welcome offer designed to give new players confidence when placing their first bet. After you register and deposit at least $10, place your initial wager on any sport or market—including Thursday's slate of afternoon MLB games like Yankees-White Sox or Cubs-Cardinals, the evening matchups featuring Mariners-Dodgers, or any of the three WNBA contests headlined by New York Liberty at Las Vegas Aces.
If your first bet loses, BetMGM returns your entire stake up to $1,500 in bonus bets. Here's how the bonus structure works: if you wager $50 or less and lose, you receive one bonus bet for your full stake. If you wager more than $50 and lose, you get five bonus bets, each worth 20 percent of your qualifying wager. For example, if you placed a $1,500 first bet on the Dodgers-Mariners game and it lost, you'd receive five $300 bonus bets totaling $1,500. These bonus bets expire seven days after issuance, so you'll need to use them promptly on upcoming games.

- Bonus bets issued if your first bet loses, up to $1,500.
