Buffalo Bills vs Kansas City Chiefs history: Which team comes out on top ahead of 2025 AFCCG?

The Buffalo Bills strolled into Arrowhead Stadium around this time in the 2020 season and lost to the Kansas City Chiefs 38–24 in the AFC Championship Game. That Bills’ side had just won its first AFC East championship in 25 years. They were led by Josh Allen, a quarterback who had just had a breakout campaign and were an up-and-coming team.

The 2024 season will see the Bills return to the Chiefs' Arrowhead Stadium for the AFC Championship Game. It will determine if Buffalo advances to its first Super Bowl since 1993.

In recent years, the Bills have suffered from playoff setbacks, especially against this Chiefs team, which has grown more and more formidable in the postseason.

When the Bills come to town on Sunday, this Kansas City team, which has won eight consecutive postseason contests, will participate in its seventh successive AFC Championship Game. In addition, the Chiefs want to make NFL history this year by becoming the first team to win three consecutive Super Bowls.

Now, let's take a look at how these two sides have matched up against each other in history.

Buffalo Bills vs. Kansas City Chiefs all-time head-to-head record

Sunday's AFC Championship Game will have a lot riding on it, particularly for the Buffalo Bills. Since the 1990s, the Bills have failed to defeat the Chiefs in the postseason.

In addition, Josh Allen, the team's quarterback, will be facing a team he has become more familiar with in recent years. He will hope to make it to the championship game for the first time in his seven-year NFL career.

Over the course of their respective clubs' histories, the two teams have squared off 56 times. With a 30-25-1 record in those games, the Bills enjoy a small advantage in the series. In the postseason, though, the Chiefs have a 4-2 lead over their AFC rivals.

The Bills won 30-21 over Patrick Mahomes and the Chiefs in their most recent meeting, which took place during the 2024 regular season. Kansas City suffered its first loss of the season in that game (Week 11). Quarterback Josh Allen and running back James Cook teamed up to score three touchdowns on the ground.

In essence, the Mahomes vs. Allen period has intensified the animosity between the two clubs. Nonetheless, the Bills' regular-season success and the Chiefs' postseason victories have generally characterized the era.
