The Kansas City Chiefs announced Monday that they will leave their historic home at Arrowhead Stadium to move to a new domed stadium with an estimated cost of $3 billion, which will be built on the Kansas side of the state and will be ready for the start of the 2031 NFL season. The move marks a profound change for one of the league's most iconic franchises and reshapes the region's sporting and political landscape. The announcement came shortly after a council of Kansas legislators unanimously approved, in a session held at the state Capitol, the issuance of STAR bonds to cover up to 70% of the cost of the stadium and a surrounding mixed-use district. These bonds will be paid for with state tax revenue generated from sales and alcohol taxes in a defined area around the complex. "The Chiefs' home games will change, but some things won't. Our fans will still be the loudest in the NFL, our games will still be the best place in the world to tailgate, and our players and coaches will still be ready to compete for championships, because on and off the field we are big dreamers and we are ready for the next chapter," said team owner Clark Hunt, as reported by ESPN. An ambitious project and a blow to Missouri. The franchise plans to build the new stadium in Kansas City, Kansas, near the Kansas Speedway and the commercial and entertainment district known as The Legends, an area that also houses Children's Mercy Park, home of Sporting Kansas City of MLS. In addition, the Chiefs will develop a new $300 million training facility in Olathe, a suburb of Kansas. Kansas Governor Laura Kelly called the historic announcement. "Today's announcement is truly historic. In fact, it's a little surreal. This announcement will impact the lives of Kansans for generations. It's a total game-changer for our state. We've always been Chiefs fans. Now we're Chiefs family," she said. The move represents a major blow to Missouri legislators and Governor Mike Kehoe, who were working on their own funding package to prevent the franchise's departure. The Chiefs had leases at Arrowhead Stadium, located in the Truman Sports Complex, that expire in January 2031. Last year,Jackson County voters rejected an extension of a local sales tax that would have helped fund the stadium's renovation and a new ballpark for the Royals. Although Clark Hunt reiterated that his original preference was to renovate Arrowhead Stadium—one of the NFL's most iconic venues and holder of the Guinness World Record for the loudest stadium roar—the lack of economic development around the stadium, the structure's deterioration, and limitations in suites and amenities ultimately tipped the scales toward a replacement.
