If you’re checking the score for the latest showdown, the Buffalo Bills came out on top. Honestly, it was a classic. In their most recent clash on November 2, 2025, the Buffalo Bills defeated the Kansas City Chiefs 28-21.
It happened at Highmark Stadium. The energy was basically electric from the jump. You’ve probably seen the highlights by now—Josh Allen looking like a man possessed and Patrick Mahomes trying to pull off another one of those late-game miracles that usually break Buffalo hearts. But this time, the script flipped.
Buffalo fans are used to the heartbreak. We all remember the "13 Seconds" game and the 2024 AFC Championship where Kansas City ended the Bills' season with a 32-29 victory. That loss in January 2025 was a gut-punch. Mahomes ran for two touchdowns and threw for another, while the Bills fell just short on a fourth-down attempt with two minutes left. But the regular season tells a different story.
Bills vs Chiefs: Why Buffalo Keeps Winning the Regular Season
It’s the weirdest trend in football right now. The Bills have now won five straight regular-season games against the Chiefs. It’s like Josh Allen has a "regular season only" cheat code. In this latest 28-21 win, Allen was nearly perfect. He went 23-of-26 for 273 yards and accounted for three total touchdowns.
Actually, he set a franchise record for completion percentage in that game. He was dicing up the Kansas City secondary like they were a high school JV squad. He found ten different receivers. Ten! Tight end Dalton Kincaid was the primary beneficiary, racking up 101 yards and a score.
The Turning Point in Week 9
The game was a see-saw. Buffalo jumped out to an early lead, but Kansas City fought back, even taking a 10-7 lead in the second quarter. Then things got weird.
- Ty Johnson powered in a 3-yard score to put Buffalo back up.
- Rashee Rice scored on a direct snap for the Chiefs.
- Josh Allen used a "tush push" to bulldoze his way into the end zone.
The real drama happened late. Buffalo kicker Matt Prater—who is somehow still kicking at 41—missed a 52-yarder that would have iced it. He "doinked" it off the right upright. That gave Mahomes the ball back with a chance to tie. You could almost hear the collective groan from Orchard Park.
But the Bills' defense, led by rookie cornerback Maxwell Hairston, stood tall. Hairston had already intercepted Mahomes once. On the final drive, Mahomes threw three straight incompletions from the Buffalo 40-yard line. The last one was batted down by Hairston as time expired. Ball game.

The Playoff Elephant in the Room
We have to talk about the discrepancy. While the Bills own the regular season, the Chiefs own the playoffs. Kansas City is 4-0 against Buffalo in the postseason during the Allen-Mahomes era.
| Competition Type | Latest Winner | Score | Date |
|---|---|---|---|
| Regular Season | Buffalo Bills | 28-21 | Nov 2, 2025 |
| Postseason (AFC Champ) | Kansas City Chiefs | 32-29 | Jan 26, 2025 |
It’s a psychological hurdle. Bills coach Sean McDermott credited the team for a "signature victory" in November, but everyone knows the real test comes in January. The Chiefs were 5-4 after that loss, while the Bills moved to 6-2. It felt like a shift, yet history suggests Mahomes finds an extra gear when the weather turns freezing and the stakes are win-or-go-home.
What This Means for the 2026 Playoff Picture
Right now, as we sit in early 2026, the ripple effects of that November game are huge. Buffalo used that win to stay in the hunt for the AFC East, though they've been chasing a surprisingly dominant New England team. For Kansas City, that loss was part of a rare mid-season slump. Andy Reid even admitted after the game that they have to "score touchdowns, not field goals."
If you're looking at the betting lines or future matchups, keep these three things in mind:
- The Underdog Factor: The Bills are no longer afraid of the Chiefs in the regular season. They play with a "nothing to lose" aggression that seems to fluster Mahomes.
- Health Matters: Buffalo lost pass rusher Michael Hoecht to an Achilles injury during that November win. Their defense has had to get creative with the pass rush ever since.
- The Mahomes Long Ball: In the latest game, Mahomes actually had a career-long 4th-and-17 conversion to Rashee Rice. He’s still dangerous; the Bills just managed to contain the damage better than usual.
To keep up with the latest playoff seeding, you should track the Bills' defensive consistency. If Hairston and safety Cole Bishop continue to play at this level, Buffalo might finally have the secondary to stop the "playoff Mahomes" magic. Keep an eye on the injury reports for James Cook as well, as his rushing versatility is the engine that makes the Bills' play-action game so lethal.
