This Sunday brings some of the most compelling matchups of the NFL season, and you can maximize your betting experience with a BetMGM bonus code. New users can claim up to $1,500 in bonus bets when they use code SI1500 on Oct. 11. Whether you're looking to place bets on the 49ers-Seahawks showdown or explore other sportsbook promos, BetMGM delivers a welcome offer that rewards both winning and losing first bets.

How the BetMGM bonus code works for NFL Week 5

The BetMGM bonus code SI1500 unlocks a straightforward welcome offer for new customers. You'll deposit a minimum of $10 and place your first real money wager on any sport or market, including the 49ers-Seahawks game on Oct. 11. If your bet wins, you keep your winnings plus any bonus bets earned. 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 equal to your stake.
If you wager more than $50 and lose, you receive five bonus bets, each worth 20 percent of your qualifying wager.
For example, if you bet $1,500 on the 49ers-Seahawks game and lose, you'll get five $300 bonus bets.
Bonus bets expire seven days after issuance and cannot be withdrawn as cash.
You'll also earn $50 in MGM Rewards Points, which you can use for bonus credits on digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers.

MGM Rewards Points are a loyalty currency that unlock multiple redemption options across BetMGM and the broader MGM ecosystem. You can learn more about the full rewards program at the BetMGM Rewards page.
