Mavericks owners froze Mark Cuban out of business opportunities in proposed arena move, lawsuit claims

Mark Cuban alleges that Mavericks owners, particularly governor Patrick Dumont, froze him out of business opportunities related to a proposed arena move north of downtown Dallas. Cuban says he had an agreement to continue running basketball operations after selling his majority stake in 2023 to the families of Miriam Adelson and Patrick Dumont, but Dumont gave full control to former general manager Nico Harrison. Cuban claims he was unaware of Harrison’s plan to trade superstar Luka Doncic to the Los Angeles Lakers in February 2025 until it was too late to object; the trade backfired and Harrison was fired in November 2025 after a slow start to the 2025‑26 season. Cuban still owns 27% of the team, with a clause allowing the Adelson and Dumont families to purchase an additional 20% of his stake. The Mavericks have signed an option to buy about 104 acres in north Dallas for a new arena slated to open in 2031, when their lease at the American Airlines Center expires. Cuban asserts his businesses were "contractually entitled to participate" in the move, which he describes as "a unique investment opportunity."}
