Rocket Mortgage FieldHouse opened in October 1994 as part of the Gateway Sports and Entertainment Complex with adjacent Progressive Field, which is home to Major League Baseball team, the Cleveland Guardians.
The naming rights for Rocket Mortgage FieldHouse have changed several times since its opening in 1994. From its opening until August 2005, it was known as Gund Arena, named for former Cavaliers owner Gordon Gund. After purchasing a majority of the Cavaliers in March 2005, Dan Gilbert bought the naming rights and renamed the building Quicken Loans Arena. In April 2019, it was renamed Rocket Mortgage FieldHouse for Quicken Loans’ online mortgage lending service.
