How the BetMGM bonus code works for College Football Week 9

The BetMGM bonus code SI1500 unlocks a welcome offer that returns your entire first bet in bonus bets if it loses, up to $1,500. You must deposit at least $10 and place a qualifying wager to activate the promotion. If your first bet on any College Football Week 9 game loses, you'll receive bonus bets equal to your original stake.

Here's how the bonus bets break down:

• If you wager more than $50, you receive five bonus bets, each worth 20 percent of your qualifying wager.
• If you wager $50 or less, you receive one bonus bet.
• For example, if you place a $1,500 first bet on a College Football Week 9 matchup and it loses, you'll get five $300 bonus bets totaling $1,500.

Bonus bets expire after seven days, so use them promptly on additional College Football Week 9 games or other sports. The bonus carries a 1x playthrough requirement, meaning you must wager your bonus bets once before requesting a withdrawal. Only winnings from bonus bet wagers can be withdrawn; the bonus bets themselves are not returned. 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.
