Mark Cuban, the longtime owner of the Dallas Mavericks, has revealed he regrets selling his majority stake in the NBA franchise in December 2023. While Cuban said he doesn't regret the sale itself, he expressed remorse over selling to Miriam Adelson and her son-in-law Patrick Dumont, who now serve as the team's controlling owners and governor.
