The tournament has been held since 1997, the inaugural year of the Big 12 Conference. Among current league members, Texas has won the most championships with five. Among original members, Kansas State has never won the event. Oklahoma State won their third championship in 2019. Iowa State discontinued their program after the 2001 season without having won a title. Having joined in 2013, TCU won titles in 2014, 2016, and 2021, while West Virginia has yet to win the Tournament.
Format and seeding
The top eight finishers from the regular season will be seeded one through eight, and will then play a two-bracket double-elimination tournament leading to a winner-take-all championship game. At the beginning of the season, the conference coaches voted to make the higher seeded team the designated home team for all games in the tournament.
