Through 2002, the entire tournament was hosted at a single venue. From 2003 through 2015, all first-round matches were played at the home court of the higher-seeded team involved. Hosting rights for the quarterfinals and semifinals were awarded to the winner of the regular season championship. The championship game was played at the home arena of the higher remaining seed. This format rewarded the regular-season champion and runner-up with a double-bye into the semifinals. The regular-season champion received the added benefit of home-court advantage in the semifinals, plus a home-court final if it won its semifinal. Beginning in 2009, the Horizon League secured an entitlement sponsorship of its men's and women's basketball tournaments with
Speedway SuperAmerica, a major gas and convenience store chain throughout the midwest United States, officially changing the name of the tournaments to "The Speedway Horizon League Men's/Women's Basketball Championship". From 2016 to 2019, the Horizon League tournament was held in
Detroit under a five-year deal, beginning at
Joe Louis Arena, adding the women's tournament in 2017 (with both events marketed under the title
Motor City Madness), and moving to the newly opened
Little Caesars Arena beginning in 2018. However, the contract with Detroit was ended a year early; the league reopened bidding for the men's and women's tournaments in 2018, with the new contract taking effect with the 2019–20 season. On January 25, 2019, the conference announced that
Indianapolis would host the men's and women's semifinals and final from 2020 to 2022, with Indiana Farmers Coliseum, now known as
Corteva Coliseum, as the venue. In 2022, the deal was extended through 2026. On August 20, 2025, the Horizon League announced a new format for the 2026 tournament. Instead of a traditional eleven-team single elimination bracket, the new format included reseeding after each round. The event started on campus sites with a play-in round for the bottom two teams (by conference record), followed by a ten-team first round. The five remaining teams then advanced to the final three rounds held at Corteva Coliseum. The bottom two teams by seeding played in the second round, while the other three teams were forwarded into the semifinals, with those winners advancing to the final. On March 12, 2026, the Horizon League announced that the men's and
women's tournaments would move their final three rounds to
Riverview Health Arena at Innovation Mile in
Noblesville, Indiana, beginning in 2027, with the contract extending through 2031. ==Horizon League Tournament results==
