The Kansas City Chiefs, based in Kansas City, Missouri, are a professional American football team that competes in the NFL's AFC West division and plays its home games at Arrowhead Stadium. Founded by Lamar Hunt in 1959 as the Dallas Texans of the AFL, the team relocated to Kansas City in 1963, adopted its current name, and joined the NFL in the 1970 merger; today it is valued at over $4.85 billion and remains under the Hunt family, led by chairman Clark Hunt. The franchise captured three AFL championships (1962, 1966, and 1969) and triumphed in Super Bowl IV in 1970, becoming the second AFL team to defeat an NFL champion, yet they later endured a long playoff drought, losing 10 of 12 postseason games from 1993 to 2017. Since 2019, however, the team has become a modern dynasty under head coach Andy Reid and quarterback Patrick Mahomes, alongside tight end Travis Kelce and defensive tackle Chris Jones, reaching five Super Bowls and winning three (LIV, LVII, and LVIII). A fascinating historical footnote is that their 1962 AFL Championship victory over the Houston Oilers, decided in double overtime, remains the longest championship game in professional football history at 77 minutes and 54 seconds.
