NFL Week 2 Sunday brings a full slate of matchups across the early and late windows, with games running throughout the day. If you're looking to place wagers on these contests, you can use a BetMGM bonus code to unlock a welcome offer. New users can claim up to $1,500 in bonus bets with code SI1500 on Sept. 20. This is one of the best sportsbook promos available for the day's action.
How the BetMGM bonus code works for NFL Week 2 Sunday
The BetMGM bonus code SI1500 unlocks a welcome offer that returns your first wager in bonus bets if it doesn't hit. Here's how it breaks down:
- You must be a first-time user and deposit at least $10 to qualify.
- Place your first real money wager on any sport or market, including NFL Week 2 Sunday games.
- If your bet loses, BetMGM returns your entire stake as bonus bets, up to $1,500.
- Bonus bets are issued as five separate $300 credits if you wagered more than $50, or as one bonus bet if you wagered $50 or less.
- All bonus bets expire seven days after issuance.
- You'll also receive $50 in MGM Rewards Points regardless of whether your bet wins or loses.
For example, if you place a $1,500 wager on a Bengals-Texans matchup and the bet loses, you'll get five $300 bonus bets to use on other NFL Week 2 Sunday games. If you win that initial $1,500 bet, you keep your winnings and can withdraw them immediately. The bonus bets themselves cannot be withdrawn as cash, but you must use them on additional wagers before cashing out any resulting winnings.
MGM Rewards Points are a loyalty currency that unlocks bonus credits for digital play at BetMGM, MGM Rewards Points toward hotel stays, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. Learn more about the program at the MGM Rewards page.

Ryan Hagen’s foray into sports betting started early. At just 14 years old, he sought out a lottery kiosk clerk with relaxed gambling mores and convinced the fella to sell him ‘Sport Select’ tickets, which were part of the original government sports betting program in his native Alberta. Now a sports betting specialist at Sports Illustrated, Ryan prefers to place his bets legally and has established himself as an authority in the sports betting industry. His roles have included lead writer, content editor, managing editor, and more. Ryan has written and edited hundreds of sportsbook reviews and countless news, analysis, and promotional pieces for some of the most prominent companies in the sports betting world. As someone who eats, sleeps, and breathes sports and sports betting, Ryan’s goal is to impart his unbiased betting knowledge to prospective bettors, allowing them to make informed decisions, whether that’s signing up for a sportsbook, mulling over a moneyline, or placing a prop bet. A prolific bettor himself, Ryan lives for the NFL season and believes that every Saturday night from September to February is akin to Christmas Eve. Ryan has a B.A. in Communications from Royal Roads University in Victoria, British Columbia. His work is widely published in the sports betting industry and in publications such as the Calgary Herald and Vancouver Magazine. Off the clock, he can be found traveling, searching for noodles, working on his golf swing, and managing his degenerate number of fantasy football teams.
