As we head into one of the biggest Sundays on the NFL calendar, BetMGM is giving you a strong way to get involved on both Patriots-Broncos and Rams-Seahawks with the BetMGM promo code MHS1500. After signing up, you can place a wager of up to $1,500 on Sunday’s conference championship games and get your stake back as bonus bets if that first play doesn’t work out here.



If you’re located in MI, NJ, PA and WV, you’ll see a different welcome option. Instead of the first-bet deal, you can wager $10 on any market and receive $150 in bonus bets once that wager wins. It’s a quick bet-and-win promotion that fans in these states can lock in.

BetMGM Promo Code MHS1500 for $1,500 First Bet Offer on NFL Championship Sunday

With the BetMGM promo code offer, you can be open to taking a bigger swing than usual on your first wager Sunday. That is because any losing wage up to $1,500 will be sent back as a bonus bet thanks to their latest welcome deal.

A smart approach could be to line up your Rams-Seahawks wagers by using the welcome offer on the earlier Patriots-Broncos game. This way, you can go into the late window knowing you either have a substantial amount of cash or bonus bets ready to fire away on those markets.

For example, with Denver’s starting quarterback Bo Nix breaking his ankle, the Patriots have climbed to a -5 point road favorite. The Broncos are +210 on the moneyline, which means you could earn a nice cash payout if your underdog bet hits, possibly something like $75 on Denver to win outright.

Then, in the case that wager fails, BetMGM would send you back that $75 stake as a bonus. You could then turn around and use those bets on several Rams-Seahawks markets.

The later game is an interesting matchup between two teams who know each other intimately. This will be the third installment of Rams-Seahawks this year, with the previous two won by the home team.

However, those games were as close as any rivalry in the 2025-26 season, with a combined 3 total points between the winners. Not to mention this game features two of the best coaches in the NFL as offensive mastermind Sean McVay takes on defensive stalwart Mike MacDonald.
