Kansas City

GEHA Field at Arrowhead Stadium holds the loudest outdoor crowd roar, which Miami's Hard Rock cannot claim. Home to the Chiefs' dynasty, its architecture amplifies energy. Hosting 6 matches, including a Quarterfinal on July 11, it features intense atmospheres with 3,500 seats removed for a 65,000-68,000 capacity. Opened in 1972, Arrowhead is the oldest US host, yet its tradition trumps newer stadiums' modernity. Midwest pricing offers high value. This venue proves heritage and noise outshine flashier counterparts.
