In 2023, Mark Cuban sold his large stake in the Dallas Mavericks for a staggering $3.5 billion price tag.
Now, not even three years later, Cuban could be involved in getting the franchise back. An “unidentified” Dallas investor group is interested in partnering with Cuban to purchase the Mavericks, per a report from NBA insider Marc Stein in his latest Substack.

The Adelson family purchased nearly 73% of the team in December 2023, but Cuban reportedly still owned 27.7% of the franchise after the sale.
Miriam Adelson, the majority owner of Las Vegas Sands, and Sivan and Patrick Dumont, the son and daughter-in-law of Adelson, were the group that purchased the large chunk in 2023, and Patrick Dumont has been the team’s Governor since then.
One source told Stein that they remain “excited about the future of the franchise” with Cooper Flagg in town.
The Mavs did land the No. 1 pick in 2025 after winning the draft lottery, and Flagg coming to Dallas is a key reason why the Dumont family is excited about the future.
Since the sale, the Mavericks made an NBA Finals appearance but lost to the Boston Celtics. Then, Dallas traded away superstar Luka Doncic in a shocking move and wound up trading away Anthony Davis at the most recent NBA trade deadline.
The big question is whether or not the Dumont family wants to sell a share of the franchise.
