BetMGM Bonus Code For Tonight’s NFL Game: Monday Night Football
BetMGM calls this their First Bet Offer, and it’s one of the highest-value promos in the industry right now. It’s designed to let you take a swing on your first wager with a built-in backup plan.
Here is the breakdown:
- Click here to activate the offer
- Create your new account.
- Deposit $20 or more to qualify.
- Place your first real-money wager on any market—like tonight’s 49ers vs. Colts spread (-5.5) or a player prop.
If your bet wins, you keep the cash and the profit like normal. But if your bet loses, BetMGM will credit your account with a full refund in Bonus Bets, up to $1,500.
It’s a great way to attack a game with some volatility—like tonight’s matchup, where the Colts are missing Daniel Jones, Sauce Gardner, and the Niners are missing Nick Bosa.

49ers vs. Colts Betting Preview
Tonight’s game at Lucas Oil Stadium is a clash of trajectories. The 49ers are road warriors (6-2 away from home) and have won four straight, averaging 31 points per game in that span. Brock Purdy is fresh off a 295-yard, 3-TD performance, and he gets to face a Colts defense that ranks 31st against the pass.
On the other side, the Colts are in survival mode. They’ve dropped four straight games, and with Daniel Joens and Anthony Richardson unavailable, they are leaning on Philip Rivers to save their season. The Colts are 5.5-point underdogs at home, and the total is sitting at 46.5.
If you’re using the BetMGM First Bet Offer, this might be the spot to look at Jauan Jennings or Brock Purdy props. With Indy’s funnel defense stuffing the run (Ranked 5th) but bleeding yards through the air, the 49ers should be throwing early and often.
