Before we get into the mountain of promos on the table this week, a quick recap of what makes this clash so electric. Every Lamar vs. Mahomes showdown has delivered fireworks.
It doesn’t get bigger than this. Week 4, primetime spotlight, and two quarterbacks who define the modern NFL: Lamar Jackson versus Patrick Mahomes. One scrambling, improvising, willing his team to survive. The other is orchestrating a dynasty at Arrowhead.
The Ravens enter 1–2, backs against the wall. Baltimore’s offense has sputtered at times, but Jackson remains the heartbeat. If he goes down, the whole ship sinks. That’s the pressure he carries into Kansas City. Meanwhile, Mahomes and the Chiefs look every bit the juggernaut they’ve been for half a decade, defending Arrowhead like it’s their personal fortress.
This isn’t just another AFC matchup. For Baltimore, it’s survival. For Kansas City, it’s supremacy. Two franchises built for the postseason, colliding in September. And yes, every fan, every bettor, every rival front office is watching.
Now, the best sportsbooks know exactly what’s at play here. They’re rolling out the red carpet with more than $2000 in bonus offers tied to Ravens @ Chiefs. Below, we look at how to take advantage of the biggest promos available and how to make them work for you.
Here’s the breakdown of the biggest sportsbook bonuses for this matchup and how to actually use them smartly
Caesars calls this their “safety net” for a reason. You sign up, place your very first wager, and if it doesn’t hit, Caesars refunds you in bonus bets, up to $1,000.
To claim this offer, create an account, deposit funds, and place a first wager of your choice.
If it loses, your stake (up to the cap) is returned as bonus bets. For example, if you want to back Lamar Jackson rushing for 100+ yards or Mahomes tossing 4+ TDs, you can shoot your shot knowing you’ve got coverage if it fails. The whole point is to swing for upside because the safety net is sitting underneath.
bet365 gives you a fork in the road. Bet just $5, and you’ll unlock $150 in bonus bets. Or, if you’re playing with bigger stakes, you can go for the $1,000 safety net bet. Choose your promo when signing up. If you’re risk-averse, grab the $150 bonus.
If you’re willing to back a big play in Ravens vs. Chiefs, go for the safety net. Say you only want a light entry, take the $150, spread it across props like Travis Kelce’s first TD, Ravens over 3.5 sacks, and Chiefs -3. If you’ve got a bankroll and want one monster bet, the $1k safety net is your move.
This one is as straightforward as it gets. Place a tiny $5 bet, and BetMGM hands you $150 in bonus bets, win or lose. Register, deposit, and wager $5 on any Ravens vs. Chiefs market. The $150 is credited to your account automatically.
Unlike safety nets, you don’t need to wait for a result to know what you’re getting.
You can use the $150 to test different Ravens vs. Chiefs angles. One bet on Lamar’s passing yards, one on Chiefs’ total points, one on the over/under…you get to experiment without burning real cash.
FanDuel is going even bigger: wager $5, get $200 in bonus bets. To claim this offer, sign up, make a deposit, and place a $5 bet on any market. The $200 comes through regardless of the outcome.
This is the best “low-entry” deal on the board. $200 gives you enough ammo to spray across multiple props and same-game parlays. Imagine splitting it into $20 shots. 10 different props, from Zay Flowers anytime TD to Chiefs covering alternate spreads.
Note: These promos are only available in states where online sports betting is legal. Terms vary, so please check the fine print before signing up.
All told. This is Ravens vs. Chiefs. Lamar vs. Mahomes. If you’re signing up fresh and stacking reloads on existing accounts, the bonus pool for Ravens @ Chiefs clears $2,000 easily. The key isn’t to chase every single promo. It’s to pick the ones that align with how you bet. Caesars, if you want the safety of first-bet insurance. bet365 if you’re deciding between a low $150 entry or a big $1,000 cushion. BetMGM for a simple $5-to-$150 boost. And FanDuel, if you want $200 in bonus bets with almost no barrier to entry.
