Bills–Chiefs rivalry
Updated: 12/11/2025, 2:56:24 PM Wikipedia source
The Bills–Chiefs rivalry is a National Football League (NFL) rivalry between the Buffalo Bills and Kansas City Chiefs. The series originated during the American Football League's inaugural season in 1960, as both the Chiefs, then known as the Dallas Texans, and Bills were charter teams in the league. Because they play in different intraconference divisions, the Bills in the AFC East and the Chiefs in the AFC West, they do not play each other every year. Instead, based on the NFL's scheduling formula, the two teams play each other at least once every three seasons and at least once every six seasons at each team's home stadium when their divisions are paired up, sometimes more often if the two teams meet in the playoffs or they finish in the same place in their respective divisions. Nonetheless, the Bills and Chiefs have had many notable moments in NFL postseason history, including the 1966 AFL Championship preceding the first-ever Super Bowl, and the 2021 AFC Divisional playoff game, which is often nicknamed "13 Seconds". Buffalo is one of 4 teams in the AFC with a winning overall record against Kansas City (the others being the Cincinnati Bengals, Indianapolis Colts, and Pittsburgh Steelers). Since 2020, the rivalry has redeveloped as both teams consistently contended for the AFC title. A rivalry has also developed between Bills quarterback Josh Allen and Chiefs quarterback Patrick Mahomes. The rivalry in the Mahomes–Allen era has largely been defined by the Bills' success in the regular season with the Chiefs owning the teams' playoff matchups, as the Bills are currently 5–1 in the regular season but the Chiefs lead the series in the playoffs with a 4–0 record. The Bills lead the overall series, 31–26–1. The two teams have met seven times in the playoffs, with the Chiefs holding a 5–2 record.
