The Broadmoor Trophy was commissioned as a replacement for the MacNaughton Cup, held in trust by Michigan Tech. In 1981, Michigan Tech left the WCHA for the Central Collegiate Hockey Association, taking the Cup with them. To fill the void, the Broadmoor Hotel presented a new trophy to the WCHA to award to their regular season champion.
When Michigan Tech returned to the WCHA in 1984, the school returned the MacNaughton Cup to the league. The MacNaughton Cup returned to being awarded to the WCHA regular season champion, while the Broadmoor Trophy began being awarded to the playoff champion.
The trophy was redesigned in 2010. The new bronze cast trophy, created by Blue Ribbon Trophies & Awards of Colorado Springs, Colo., is a recreation of the famous Broadmoor Hotel.
The Broadmoor Trophy has been awarded every year since 1982. From 1982 to 1984, the trophy was awarded to the WCHA regular season champions. North Dakota's 8 Broadmoor trophies leads the WCHA. Minnesota is second with 7.
