Dumont Family Takes Full Control of the Mavericks at 69 Percent

The Dallas Mavericks have a new controlling ownership structure after Patrick Dumont and his wife Sivan purchased Miriam Adelson's shares in the franchise last month. The deal, reported by ESPN's Tim MacMahon and confirmed in coverage on November 4, gives the Dumont family a 69 percent controlling stake. Mark Cuban retains a 27 percent share, with Mary Stanton holding the remaining 4 percent. In practical terms, little changes overnight: Patrick Dumont has served as the team's governor since the Adelson and Dumont families bought control from Cuban in December 2023, and he has increasingly steered the franchise's basketball and business operations. The longer-term picture is where the move matters. Under the original sale terms, Dumont holds an option to buy a further 20 percent from Cuban at the original 3.5 billion dollar valuation, which would take the family's stake to 89 percent. Dumont has also talked up a new arena project, targeted for 2031, on land near the former Valley View Mall site in North Dallas. For Mavericks fans, the message is continuity with ambition: the same governor, now with fuller control, and a long-term building plan to match.
