The BetMGM bonus code SI1500 unlocks a welcome bonus that returns your entire first bet in bonus bets if it loses. You can wager up to $1,500 on any market for the Oklahoma City vs. Dallas game on Oct. 28. If your initial bet wins, you keep the winnings. If it loses, you receive bonus bets equal to your stake, up to $1,500.

• 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 equal to your stake.
• For example, a $1,500 losing wager on Oklahoma City vs. Dallas returns five $300 bonus bets.

The bonus bets expire after seven days, so use them promptly on any sport or market. The bonus carries a 1x playthrough requirement, meaning you must wager the bonus bets once before withdrawing any winnings. You have until Oct. 18, 2026, at 11:59 PM ET to claim this offer.
