Dumont Family Takes Control of Mavericks Ownership

Patrick Dumont and his wife, Sivan Ochshorn, have taken control of the Dallas Mavericks after purchasing Miriam Adelson’s majority stake in October 2026. The team said the transaction gives the couple’s family a 69% share of the franchise. Ochshorn is Adelson’s child, while Dumont is married to her.

Mark Cuban, who transferred control of the team to the Adelson and Dumont households in December 2023, retains a 27% stake. Dumont also has the option to acquire an additional 20% from Cuban at the original $3.5 billion valuation. The NBA’s board of governors approved the ownership change.

Dumont said the family’s focus includes investing in Dallas and pursuing a new arena intended to serve as the Mavericks’ home for 40 years. The organization is working toward a venue on the site of the old Valley View Mall in North Dallas, with an opening targeted for 2031.

The transition comes amid continuing fallout from the February 2025 trade that sent Doncic from Dallas to the Lakers. The team later replaced general manager Nico Harrison with Masai Ujiri as president and named Mike Schmitz general manager. With Dusty May as coach, Dallas has opened the season 4-3.

In a statement, the Dumont family said it was committed to building a championship team, supporting fans and expanding the organization’s presence in the community. Dumont also said he hoped to earn Cuban’s pride in the team’s future success.
