How the BetMGM bonus code offer works for USA vs. Australia
The BetMGM bonus code SIBONUS50 unlocks a $1,500 First Bet offer for new users. Place your first real money wager on USA vs. Australia in Group D, and if it loses, BetMGM will return your entire stake in bonus bets, up to $1,500. This is one of the more generous welcome offers available at any major sportsbook.
Here is how the bonus bets break down based on your wager amount:
- If you wager $50 or more and lose, you receive five bonus bets, each worth 20% of your qualifying wager. For example, a $1,500 losing bet returns five $300 bonus bets totaling $1,500.
- If you wager less than $50 and lose, you receive one bonus bet equal to your stake.
- Bonus bets expire seven days after issuance.
- BetMGM does not return your stake when you use bonus bets to place subsequent wagers.
- A minimum deposit of $10 is required to qualify.
Say you back the United States to win at +120 and wager $200. If the Americans deliver on their predicted 2-0 result, you collect your winnings immediately. If the Socceroos pull off an upset and your bet loses, BetMGM returns $200 in bonus bets, split into five $40 credits. Either way, you also receive $50 in MGM Rewards Points just for participating.
MGM Rewards Points are part of BetMGM's loyalty program and can be redeemed in several ways, including bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the program at the BetMGM Rewards page.
