The 2026 Big 12 Conference men's basketball tournament (branded as the 2026 Phillips 66 Big 12 Men's Basketball Tournament for sponsorship reasons) was a postseason men's basketball tournament for the Big 12 Conference. It was played from March 10âÂÂ14, 2026, in Kansas City, Missouri at the T-Mobile Center. The winning team, Arizona, received the conference's automatic bid to the 2026 NCAA tournament.
All sixteen teams participated in the tournament. The top eight teams received a first round bye and the top four teams received a double bye into the quarterfinals.
Teams were seeded by record within the conference. Ties were broken by head-to-head results, then results vs. the top seed in the conference and going down the standings until the tie was broken.

In February 2026, the Big 12 announced that both the women's and men's tournaments would be played on a glass LED court built by ASB GlassFloor; the technology would allow for video, animated and interactive graphics, and real-time sponsorship placements to be displayed on the court. While a similar court was used for portions of NBA All-Star Weekend in 2024, the women's and men's tournaments marked the first time that a glass court would be used for official competitive play in the United States.
The court faced a mixed reception from players, with some finding the surface to be more slippery than a traditional wooden court. After a first round game between Kansas State and BYU, Kansas State player Taj Manning heavily criticized the court: "The lights and stuff caused [Kansas State player] Khamari [McGriff] to get a migraine. ItâÂÂs a bad court. They shouldnâÂÂt bring it back. ItâÂÂs just an eyesore. ItâÂÂs constantly changing and stuff and flashing different lights. Nobody wants to play on that floor."
During a quarterfinal game between Texas Tech and Iowa State, Texas Tech player Christian Anderson slipped on the court and injured his groin. Shortly after the game, in consultation with the coaches of the remaining teams, the Big 12 announced that the glass court would be removed and replaced with a standard wooden court for the semi-finals onward.
