Patrick Dumont and his wife, Sivan, are now the controlling owners of the Dallas Mavericks after buying Miriam Adelson’s share of the franchise in October, according to ESPN’s Tim MacMahon.
That move gives the Dumont family 69% ownership of the NBA club. Adelson is Sivan Dumont’s mother, and during her time as controlling owner, she had minimal involvement with the Mavericks.
The ownership shift traces back to December 2023, when Adelson and the Dumonts bought Mark Cuban’s majority stake in the team. Patrick Dumont then stepped in as team governor, replacing Cuban, and later became the club’s head decision-maker when he signed off on the Luka Doncic-Anthony Davis trade.
Cuban still holds a 27% share of the Mavericks. Under the terms of the 2023 sale, Dumont can buy an additional 20% from Cuban at the original $3.5-billion valuation.
“It’s really about long-term investment in the city of Dallas,” Patrick Dumont told ESPN’s Tim MacMahon. “The Dumont family is really committed to building what we hope is the best arena in the NBA, a really significant investment in the city that will help create the new 40-year home for the Dallas Mavericks, a great experience for our fans and inspire our team to win championships.”
Dumont also said the family plans to examine that option over time.
“Our plan is to look at that and to do that over time,” Dumont said. “I just have to tell you: I love Mark.
He’s been a great family friend for a really long time. He’s just a super passionate Mavs fan and he’s frustrated.
I respect it.
“We’re going to hopefully do him proud. That’s my goal - to make all of our Mavs fans super proud about the success of the team and win a championship.”

Hawks Fans May Be Split On This Blockbuster Trade Return
A speculative three-team trade idea from Bleacher Report has put Dallas back in the middle of another roster conversation, this time with Grant Hughes laying out a framework that would send Kyrie Irving and Nickeil Alexander-Walker to Detroit while the Mavericks would come away with a package built around younger players and future flexibility. The concept is aimed at helping the Pistons upgrade their backcourt, while Atlanta would be the team collecting the biggest pile of draft capital in the deal.
For Dallas, the appeal would have to be about balancing present and future, but the proposal also invites the usual question that comes with any blockbuster involving a star guard: is the return enough? Hughes framed the idea as a hypothetical, not something any team has confirmed, and the Mavericks would have to weigh whether the mix of players and pick swaps truly matches the value of moving on from Irving in a deal that leaves plenty of room for debate.

Mavericks Suddenly Need Santi Aldama More Than Ever
The Mavericks recent loss to the Kings put a spotlight on a problem that has been hard to ignore whenever the perimeter game goes cold: the offense can get cramped in a hurry without enough reliable shooting and spacing. With Kyrie Irving and breakout guard Walter Clayton Jr. out, Dallas had fewer ways to stretch the floor and create clean looks, which only sharpened the need for another versatile piece who can keep the attack from bogging down.
Santi Aldama is the kind of frontcourt addition the Mavericks have been waiting on because he can help in more than one way, from opening the floor to giving the offense another layer of flexibility. He is still working his way back from knee surgery, and his status remains in question as Dallas looks for answers before the next game. [Read more 🡒]
Mavericks Just Got A Harsh Reminder About Life Without Kyrie
The Mavericks got a rough reminder Tuesday night that their margin for error shrinks fast when Kyrie Irving is out of the lineup. Dallas fell 115-100 to a Sacramento team that had been winless, and the offense never found much rhythm without its usual closer on the floor. Daniel Gafford gave the Mavs a strong scoring night inside, but the overall attack lacked the kind of consistent pressure that usually keeps them afloat.
Cooper Flagg had an especially difficult outing and never got comfortable enough to carry the load on the perimeter. With Irving sidelined and the supporting cast unable to fill the gap, Dallas spent too much of the night searching for answers rather than dictating the game. It was the kind of loss that can linger, because it exposed just how quickly the Mavericks can look ordinary when one of their top creators is missing. [Read more 🡒]
