Since the American Football League was established in 1960, the Broncos and the Chiefs have shared the same division, first being the AFL Western Conference, and since the AFL–NFL merger, the AFC West. For years, the rivalry has featured two of the best home-field advantages in the league. CBS ranked this rivalry as the No. 4 NFL rivalry of the 1990s in 2020.
The Dallas Texans/Chiefs dominated the Broncos in the 1960s, the decade of the AFL, winning 19 of 20 games. The Broncos have responded since then, winning the series from the 1970s to 2000s. The Chiefs snapped this streak in the 2010s when they won 11–9. The Chiefs/Texans lead the series 72–56, but since the Texans moved to Kansas City and became the Chiefs, they lead 66–56. Dallas swept all six meetings in the rivalry's first three years.
In the 2010s, Peyton Manning went 7–1 against the Chiefs as a member of the Broncos from 2012–2015. The Chiefs took control of the series after defeating the Broncos in 2015 in the final meeting with Manning at quarterback. This started a 16-game win streak for Kansas City over Denver. Until 2023, the Chiefs had gone 15–0 against the Broncos since Manning retired following the 2015 season, and quarterback Patrick Mahomes won his first 12 career starts against Denver. Combined, the two teams have won the last 13 AFC West Division titles from 2010–2022, and were the only teams to win the AFC West in the 2010s.
