How the BetMGM bonus code works for NBA Tip Off
The BetMGM bonus code SI1500 unlocks up to $1,500 in bonus bets when you place your first real-money wager on any sport, including the NBA games on Tuesday. You must enter the code SI1500 during registration to qualify. Here's how the offer breaks down:
- If you wager more than $50, you receive five bonus bets, each worth 20 percent of your qualifying wager.
- If you wager less than $50, you receive one bonus bet.
- Bonus bets expire after seven days.
- The bonus carries a 1x playthrough requirement.
Let's say you place a $1,500 qualifying bet on one of Tuesday's NBA matchups and your bet loses. You'll receive five $300 bonus bets back, totaling $1,500 in bonus credits to use on future wagers. If your first bet wins, you keep your winnings and don't receive bonus bets. You must deposit a minimum of $10 to activate this welcome offer, and you have until Oct. 18, 2026, at 11:59 PM ET to claim it.

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.
