New bettors can claim a welcome offer on Sunday, Sept. 13 when the NFL's full slate of Week 1 games kicks off. Use the BetMGM bonus code "SI1500" to earn up to $1,500 in bonus bets when you place your first wager. This is one of the best sportsbook promos available today.

How the BetMGM bonus code works for NFL Week 1 Sunday

The BetMGM bonus code "SI1500" unlocks a welcome offer that returns your entire first bet in bonus bets if it loses, up to $1,500. You'll need to make a minimum $10 deposit and place a real money wager on any market to qualify. If your first bet on any of Sunday's games loses, BetMGM will credit your account with bonus bets equal to your stake.

Here's how the bonus bets break down based on your wager amount:

If you wager more than $50, you receive five bonus bets, each worth 20 percent of your qualifying wager.
If you wager $50 or less, you receive one bonus bet.
For example, if you bet $1,500 on the Bills-Texans game and lose, you'll get five $300 bonus bets totaling $1,500.

Bonus bets expire seven days after they're issued, so you'll want to use them quickly on upcoming games. You'll also earn $50 in MGM Rewards Points regardless of whether your first bet wins or loses. MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers. Learn more about the program at the MGM Rewards page.

When you use the bonus bets from a losing first wager, remember that BetMGM does not return your stake. You'll only receive the winnings from those bonus bets. If your first bet wins, you can withdraw your winnings immediately without any bonus bet requirements.
