How the BetMGM bonus code works for Week 7 sports

The BetMGM bonus code SI1500 unlocks a welcome bonus that returns your entire first bet in bonus bets if it loses, up to $1,500. You must deposit a minimum of $10 and place a qualifying wager to activate the promotion. If your first bet on the New England versus Chicago game, an NBA contest, or any other event loses, you'll receive bonus bets equal to your stake.

Here's how the bonus breaks down:

  • Wagers of $50 or more earn five bonus bets, each worth 20 percent of your qualifying amount.
  • Wagers under $50 earn one bonus bet.
  • For example, if you wagered $1,500 on Thursday's NFL game and lost, you'd receive five $300 bonus bets totaling $1,500.
  • Bonus bets expire after seven days, so use them promptly during Week 7 action.
  • The bonus carries a 1x playthrough requirement before you can withdraw winnings.
  • You have until Oct. 18, 2026, at 11:59 PM ET to claim this offer.

This BetMGM promotion is available to first-time users in the following states: AZ, CO, DC, IA, IL, IN, KS, KY, LA, MD, MI, MS, NC, NJ, OH, PA, TN, VA, WV, WY. It is not available in NV, NY, or Ontario, Canada.

RYAN HAGEN

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.
