Miriam Adelson and her son-in-law Patrick Dumont control the Dallas Mavericks, having bought a majority stake from longtime owner Mark Cuban in December 2023. The Adelson-Dumont families hold 69% of the team, with Cuban’s remaining share reduced to 27% and no operational control.
Patrick Dumont has since moved into the top operational role too — he was promoted to CEO and chairman in 2026, giving the family full command of both ownership and day-to-day team direction.

Key Ownership Highlights
