An unidentified Dallas investor group is interested in partnering with former owner Mark Cuban in attempt to buy back the Mavericks, Marc Stein reports at The Stein Line (Substack link).
As Stein writes, Cuban was the majority owner of the Mavericks for 23-and-a-half seasons until he sold the team to the Dumont and Adelson families in 2023. Cuban still holds a 27% stake in the Mavericks, but the Dumont and Adelson families have the option to buy another 20% of Cuban’s shares within the next year if they so choose, according to Stein.
It’s unclear if the two families have any interest in selling the team so soon after they purchased it. A source close to team governor Patrick Dumont told The Stein Line that “the family remains excited about the future of the franchise and the Cooper Flagg era.”
Cuban, who has been acting as an unofficial adviser to Dumont since former president of basketball operations Nico Harrison was fired in November, declined to comment when reached by Stein.
Cuban claimed at the time he sold the team that he would remain the top decision-maker in the basketball operations department, Stein notes. However, that turned out to be inaccurate, and Cuban was reportedly pushed out of the team’s inner circle by Harrison.
Harrison’s stunning and incredibly unpopular decision last year to trade franchise player Luka Doncic to the Lakers for Anthony Davis, Max Christie and a 2029 first-round pick eventually resulted in his ouster. Matt Riccardi and Michael Finley have been operating as the team’s co-general managers, and orchestrated last week’s deadline deal which sent Davis to Washington.
Although Harrison often drew the brunt of fans’ ire, his dismissal hasn’t entirely quelled the unrest in Dallas, Stein adds. Dumont recently received mild boos when he was sitting courtside during Mark Aguirre‘s jersey retirement on January 29 (YouTube link).

Hey NBA: if you want to come off as less corrupt, maybe do not have shadowy groups of anonymous rich people literally buy teams!

As a mavs fan I was sad to see Mark sell majority stock in the team, he rejuvenated the entire fan base and organization and brought us our first and only championship, though he would’ve never traded Luka and it would’ve definitely kept us out of the lottery for Flagg
I’m so tired of Cuban. The BS he was spinning around the Luka trade was ridiculous. Wish he would just move on. Buy a premier league club or something.
