If you just looked at the Chiefs vs Bills score from their latest meeting on November 2, 2025, you’d see a 28-21 victory for Buffalo and probably think, "Oh, Josh Allen finally has Patrick Mahomes' number." Honestly? That’s only half the story. It’s the kind of game that leaves you staring at the box score trying to figure out how a team like Kansas City, led by the greatest quarterback of this generation, looked so human for four quarters.
Buffalo walked out of Highmark Stadium with a 6-2 record, while the Chiefs slipped to 5-4. It was a statement. But if you’ve followed this rivalry for more than a week, you know the regular season is just a teaser trailer for the heartbreak that usually follows in January.
The Reality Behind the Chiefs vs Bills Score
The November 2025 matchup wasn't some fluke blowout. It was a grind.
Buffalo jumped out to an early 7-0 lead thanks to a 23-yard touchdown pass from Josh Allen to Dalton Kincaid. The stadium was vibrating. You’ve seen this movie before, though—Mahomes usually snaps his fingers and the lead evaporates. Not this time. While the Chiefs did scrape together a 10-7 lead in the second quarter after a Harrison Butker field goal, the Bills responded with two straight touchdowns.

By halftime, Buffalo led 21-13.
What’s wild is how the Bills' defense treated Mahomes. They didn't just play "prevent" defense; they hunted. Mahomes finished with a 44.1% completion rate. That is the lowest of his entire nine-year career. He went 15-of-34 for 250 yards. He was sacked three times and hit 15 times. Basically, the Bills' defensive front turned the pocket into a mosh pit.
Why the Regular Season Score is a Liar
Here is the weirdest stat in professional football right now: The Buffalo Bills have won five straight regular-season games against Kansas City.
- November 2, 2025: Bills 28, Chiefs 21
- November 17, 2024: Bills 30, Chiefs 21
- December 10, 2023: Bills 20, Chiefs 17
- October 16, 2022: Bills 24, Chiefs 20
- October 10, 2021: Bills 38, Chiefs 20
If you only watched football from September to December, you’d think the Bills were the undisputed kings of the AFC. But then January hits. In the playoffs, the script flips so hard it gives you whiplash. The Chiefs are 5-2 all-time against the Bills in the postseason, including a soul-crushing 32-29 win in the AFC Championship back on January 26, 2025.
That game was a classic. It had everything: lead changes, a 29-29 tie late in the fourth, and Mahomes rushing for a 10-yard touchdown to seal the deal. It’s why the Chiefs vs Bills score in November feels like a "moral victory" for Buffalo fans while Chiefs fans just shrug and point at their Super Bowl rings.

Breaking Down the November 2025 Stats
The game was actually decided in the final 17 seconds. Mahomes had the ball at Buffalo's 40-yard line. He threw three straight incompletions. The last one was a desperate heave toward the end zone that got batted down by Maxwell Hairston, a rookie who had already intercepted Mahomes earlier in the game.
Buffalo’s offensive stars showed up too:
- Dalton Kincaid: 101 receiving yards and a touchdown.
- James Cook: 114 rushing yards, keeping the clock moving when it mattered.
- Josh Allen: 2 rushing touchdowns and a passing TD.
Kareem Hunt and Rashee Rice found the end zone for the Chiefs, but it wasn't enough to overcome a stagnant passing attack. Andy Reid later admitted that you simply can't settle for field goals against a team like Buffalo. He’s right.
The Playoff Seeding Chess Match
This win gave Buffalo a 2.5-game edge over the Chiefs in the playoff race. That’s huge because playing at Highmark Stadium in the snow is a much different beast than playing at Arrowhead. However, Buffalo is still looking up at the New England Patriots in the AFC East. It’s a messy season.
The Chiefs, on the other hand, hit a rare milestone under Andy Reid: losing four of their first nine games. That’s only happened three times since he took over in 2013. Is the dynasty crumbling? Probably not. We've said that before, and then Mahomes ends up holding a trophy in February.
Actionable Insights for Fans and Analysts
If you are tracking this rivalry for betting, fantasy, or just pure bragging rights, keep these things in mind:
- Home Field is Key but Not Guaranteed: The Bills dominate at home in the regular season, but Mahomes has proven he can win in Orchard Park when the stakes are at their highest.
- Watch the Mahomes Completion Rate: When Mahomes drops below 60%, the Chiefs almost always lose. Buffalo has figured out a "disguise and blitz" package that clearly rattles him.
- The "13 Seconds" Ghost: No matter what the Chiefs vs Bills score says, Buffalo plays with a certain level of desperation. They are trying to exorcise the demons of past playoff collapses.
- Prop Bet Value: Dalton Kincaid has become the primary target in this specific matchup. If you're looking at player props for future meetings, he's a safer bet than the wideouts.
The next time these two face off, don't just look at the final numbers. Look at the pressure rate on the quarterback. Buffalo won the battle in November 2025 because they lived in the Chiefs' backfield. Whether they can do that in a freezing January playoff game is the only question that actually matters.
