In Their Own Story

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. The Adelson-Dumont families took 69% ownership and previous controlling owner Mark Cuban's share was reduced to 27%. According to the Dallas Morning News, the purchase was the realization of a decade-long passion to buy an NBA franchise. 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. 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. Dumont also stated there were no plans to relocate the team away from Dallas. The following season, the Mavericks won the first pick in the 2025 NBA draft lottery and selected Cooper Flagg, a Duke University alum. 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. 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.' 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. On May 4, 2026, the Dumont-led Mavericks hired Masai Ujiri as their president and alternate governor. On May 8, 2026, the Mavericks hired Mike Schmitz as their general manager to replace the embattled Nico Harrison. 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. The Stars, in their countersuit, claimed that the Mavericks had breached their lease agreements by moving their headquarters to Las Vegas, Nevada in 2024. In May 2026, a Texas judge ruled in favor of the Mavericks and gave control of the American Airlines Center to the team.
