New bettors can claim up to $1,500 in bonus bets with the BetMGM bonus code SI1500 ahead of the Chiefs vs. Seahawks matchup on Oct. 25. This welcome offer is part of BetMGM's current sportsbook promos available to first-time users.

How the BetMGM Bonus Code Works for Chiefs vs. Seahawks

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 on any market, including the Chiefs vs. Seahawks game. If your first bet wins, you keep your winnings and the bonus doesn't apply, but if it loses, you'll receive bonus bets equal to your stake.

Here's how the bonus structure works:

• 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.
• For example, if you place a $1,500 bet on the Chiefs vs. Seahawks and lose, you'll get five $300 bonus bets.

The bonus bets expire after seven days, and you must meet a 1x playthrough requirement before withdrawing any winnings. The offer expires on Oct. 18, 2026, at 11:59 PM ET. You have until then to claim this welcome bonus and place your qualifying bet on the game.
