How the BetMGM bonus code SI1500 works for NBA Cup games

The BetMGM bonus code SI1500 unlocks the "Exclusive Up to $1,500 in Bonus Bets" welcome offer for new users. A code is required, and you must enter SI1500 during sign-up. Friday's NBA Cup group-stage games give you plenty of markets for your first wager.

Here is how the offer works. You deposit at least $10 and place a real-money first bet of up to $1,500 on any sport or betting market, including an NBA Cup game. If that first bet loses, BetMGM returns your stake, up to $1,500, in Bonus Bets.

Here are the key terms:

  • The offer is for new users who are at least 21 and located in an eligible state.
  • You must sign up through the BetMGM Sportsbook app.
  • You must deposit at least $10 and place a real-money wager to activate the welcome bonus.
  • If you wager more than $50, BetMGM awards five Bonus Bets, each worth 20% of your qualifying wager. If you wager less than $50, you get one Bonus Bet.
  • Bonus Bets expire after seven days.
  • The Bonus Bets carry a 1x playthrough requirement.
  • You have until Oct. 18, 2026, at 11:59 PM ET to claim the offer.
  • You must wager the Bonus Bets once before you can request a withdrawal, and only the winnings from the wager are returned, not the Bonus Bets themselves.
  • You cannot use BetMGM if you are on any self-exclusion list for gambling.

Here is what happens if you win or lose on an NBA Cup game. Say you bet $1,500 on the Knicks at the Pacers and the bet wins. You collect your winnings in cash, and the offer does not apply.

Now say that same $1,500 wager loses. You would receive five $300 Bonus Bets, adding up to $1,500. In my own test, I wagered the full $1,500 qualifying amount, lost, and received $1,500 in Bonus Bets.

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’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.
