The Dallas Mavericks, commonly known as the Mavs, are a professional basketball team based in Dallas, Texas.

For over two decades, the face of Mavericks ownership was Mark Cuban, the billionaire entrepreneur and television personality best known for his role on Shark Tank. Cuban purchased a majority stake in the team in 2000 for $285 million and transformed the franchise into a modern powerhouse. Under his leadership, the Mavericks won their first and only NBA title in 2011.
But in December 2023, Cuban made headlines when he agreed to sell a majority stake in the Mavericks to the Adelson family, specifically to Miriam Adelson and her son-in-law Patrick Dumont. The deal was reportedly valued at around $3.5 billion. While Cuban retains a minority stake and remains in charge of basketball operations, the controlling interest now belongs to the Adelson family.
Who is the owner of the Dallas Mavericks in 2025?
As of April 2025, Miriam Adelson and her family own most of the Dallas Mavericks. Miriam is a very rich doctor and the widow of casino businessman Sheldon Adelson. She and her daughter Sivan Dumont and son-in-law Patrick Dumont bought 69% of the team for $3.5 billion in December 2023. Patrick Dumont is the team’s main leader and talks to the NBA for the family.
Miriam Adelson is worth about $27 billion, making her one of the richest women in the world. Her money mostly comes from casinos in places like Macau and Singapore. Patrick Dumont also helps run those casinos and is now very involved in how the Mavericks are managed.
About the New Owners – Adelson Family
The new majority owners of the Mavericks are tied to one of America’s most influential business empires:
- Miriam Adelson is a billionaire physician and the widow of Sheldon Adelson, the late casino mogul and founder of Las Vegas Sands Corporation.
- Patrick Dumont, her son-in-law, is the President and COO of Las Vegas Sands and now serves as a key figure in Mavericks ownership.
The family’s entry into the NBA is part of a broader vision to expand their business and entertainment footprint in Texas, particularly around the Dallas area, where they have plans to develop an entertainment and casino resort if legislation permits.
About Mark Cuban:-
Mark Cuban, who bought the Mavericks in 2000, still owns 27% of the team. He doesn’t control the whole team anymore, but he still helps with basketball decisions like choosing players. Cuban is still very important to the team, even though he sold the bigger part.
History of Dallas Mavericks Ownership: Who Owned the Team Before?
- Don Carter (1980–1996): He started the team in 1980 and named it after the TV show Maverick. He loved basketball and helped the team make it to the playoffs in the 1980s.
- H. Ross Perot Jr. (1996–2000): He bought the team in 1996. The team did not play well during this time.
- Mark Cuban (2000–2023): Cuban changed everything! He made the team better, helped them win the NBA championship in 2011, and made fans feel included. He was very hands-on and fun to watch.
- Adelson-Dumont Families (2023–Now): They bought the team in late 2023 and are planning to make big changes, like building a new arena by 2032.
The Controversial Luka Dončić Trade and Ownership’s Role
In February 2025, the Mavericks traded star player Luka Dončić to the Los Angeles Lakers. In return, they got Anthony Davis, Max Christie, and a future draft pick. This upset many fans.
The trade was approved by Patrick Dumont and done by general manager Nico Harrison. Mark Cuban was not part of the decision. He said he was “shocked” and didn’t like the trade. Many fans protested and even made a mural saying “Fire Nico.”
Some people think the trade was about money, since Luka could have signed a huge contract worth $350 million. But Patrick Dumont said it was not about saving money — it was about trying a new strategy.
Institutional Ownership & Valuation
While the Mavericks are not a publicly traded company, estimates from Forbes and Sportico place their current franchise valuation at around $3.5 to $4 billion, making them one of the most valuable NBA teams. The sale to the Adelsons reinforced this value, showing the franchise’s growth from a modest 1980 expansion team to a modern sports giant.

Why Did Mark Cuban Sell the Team?
Mark Cuban sold his big part of the Mavericks to work with people who are good at real estate and building things. He believes the future of NBA teams includes more than just basketball, like building new arenas and fun places for fans. The Adelsons are experts at this, so they are helping Cuban with his big plans.
Also, Cuban wanted to make sure the team stayed strong while TV and media companies go through changes. As a thank-you, Cuban and the Adelsons gave $35 million in bonuses to team workers in 2024!
What Are the Adelsons Planning Next?
The new owners want to keep the Mavericks in Dallas. Even though they own casinos in Las Vegas, they say they will not move the team. Patrick Dumont said, “The Dallas Mavericks are the Dallas Mavericks.”
Some fans don’t agree with how they run the team, especially after the Luka trade and higher ticket prices (up by 8% for next season). Also, some people don’t like Miriam Adelson’s political views, but the family is focusing on long-term goals like a new arena and better fan experience.
The Mavericks’ Future
Even with changes, the team is still fighting to win. In April 2025, the Mavericks beat the Sacramento Kings 120–106 in the play-in tournament. Anthony Davis and Klay Thompson are trying to help the team reach the playoffs again.
Fans, also called MFFLs (Mavs Fans For Life), are hopeful. They still remember great moments — like the 2011 championship, Dirk Nowitzki’s loyalty, and Luka’s magic. The team may be changing, but the love for Mavericks basketball stays strong.
Conclusion
The Dallas Mavericks have gone through a major ownership change, with Miriam Adelson and Patrick Dumont now holding the majority stake in the team. Mark Cuban, once the sole face of the Mavericks, still plays a vital role in basketball decisions, but the future of the team’s operations and potential ventures into casinos or entertainment complexes now lies with the Adelson family.
With one of the NBA’s brightest stars, Luka Dončić, and an ambitious new ownership team, the Mavericks are poised for an exciting next chapter.
