After his 2009 marriage to Sivan Ochshorn, daughter of Miriam Adelson, Dumont began working for the Adelson-owned Las Vegas Sands Corp.. He was promoted to Chief Financial Officer (CFO) in 2016, President and Chief Operating Officer (COO) in 2021, and Chief Executive Officer (CEO) and Chairman in 2026.
In 2023, the Adelson-Dumont family purchased the majority controlling interest in the Mavericks, with Dumont becoming the team's governor, replacing Mark Cuban. In his role as governor, Dumont was a significant decision-maker in the February 2025 Luka Dončić–Anthony Davis trade.
Early life and career
Dumont grew up in Brooklyn, New York. He earned a bachelor's degree in mechanical engineering from Johns Hopkins University and an MBA from Columbia Business School.[1]
Business career
Dumont's early career was in investment banking. He worked at Miller Buckfire and Bear Stearns.[1]
After his marriage to Sivan Ochshorn, the daughter of Miriam Adelson, Dumont joined Las Vegas Sands Corp., owned by Sheldon Adelson and his family, in June 2010. He served in a variety of strategic, operating, and finance positions, rising to senior vice president before being named the company's CFO in March 2016.[1][2] After the death of Sheldon Adelson on January 11, 2021, Dumont was elevated to President and COO, positioning him as the heir to the family's gambling empire.[3] In 2026, Dumont was promoted to CEO and Chairman.[4]
In his role overseeing the Adelson family's investments, Dumont brokered Sheldon Adelson's 2015 purchase of the newspaper Las Vegas Review-Journal for $140 million .[1][5][2]
Dallas Mavericks
The NBA Board of Governors unanimously approved the sale of the controlling ownership interest of the Dallas Mavericks to Miriam Adelson and Sivan and Patrick Dumont on December 27, 2023. Dumont became the Mavericks' governor and representative to the NBA Board of Governors.[6] The Adelson-Dumont families took 69% ownership and previous controlling owner Mark Cuban's share was reduced to 27%.[7] Dumont's low profile was contrasted with that of the big persona and pop culture visibility of previous majority owner Cuban.[7]
According to the Dallas Morning News, the Adelson-Dumont family's purchase of the Dallas Mavericks was the realization of a decade-long passion to buy an NBA franchise.[7] Long-term, Dumont expressed the potential to develop destination resorts in Texas, including the opportunity to build a new arena for the Mavericks as part of a large-scale entertainment complex in a destination resort.[1]
In late 2024, Dumont played a pivotal role in thawing relations between the NBA and China, which frayed following Houston Rockets General Manager Daryl Morey tweeted in support of the 2019–2020 Hong Kong protests. Dumont announced the NBA China Games, to be held at the Venetian Arena in Macao in October 2025.[8]
Dumont was the "ultimate decision maker" of the widely criticized blockbuster trade of star Luka Dončić to the Los Angeles Lakers on February 1, 2025, according to Mavericks general manager Nico Harrison.[9] In his first public comments since the trade on February 9, Dumont backed the trade, stating: "If you look at the greats in the league, the people you and I grew up with, Jordan, Bird, Kobe, Shaq, they worked really hard, every day, with a singular focus to win. And if you don’t have that, it doesn’t work. And if you don’t have that, you shouldn’t be part of the Dallas Mavericks." Multiple media outlets questioned Dumont's knowledge of NBA history for including Shaquille O'Neal in the list.[10][11]
He also stated there were no plans to relocate the team away from Dallas.[12][13]
On November 11, 2025, Dumont fired general manager Nico Harrison after ongoing fan unrest and a struggling 3–8 start to the season, with fans chanting “Fire Nico” at Dallas Mavericks home games in the American Airlines Center.[14][15]
He then penned an open letter to Mavericks fans regarding the firing of Harrison, stating that he was “fully committed to the success of the Mavericks.”[16][17]
The night before the firing, Dumont had a courtside conversation with a Mavericks fan wearing a Lakers Luka Dončić jersey, during which he accepted the fan’s apology for a rude gesture the fan had directed toward Dumont during a previous game and acknowledged remorse about the team’s decision to trade Dončić.[18][19]
On October 29, 2025, Dumont and the Mavericks became involved in an ongoing lawsuit against the Dallas Stars over shared use of the American Airlines Center. The Mavericks claimed that the Stars breached their lease agreements by moving their headquarters to Frisco, Texas in 2003. Dumont asserted that "the Stars are holding the American Airlines Center hostage," while the Stars, led by owner Tom Gaglardi, quickly responded with a countersuit seeking to restore normal operations at the arena. Stars team officials labeled the Mavericks' lawsuit as "nothing short of an attempted hostile takeover of the management of the AAC."[20] The Stars, in their countersuit, claimed that the Mavericks had breached their lease agreements by moving their headquarters to Las Vegas, Nevada in 2024.[21]
Personal life
Dumont married Sivan Ochshorn, Miriam Adelson's second daughter from her first marriage, in 2009.[1]
