Mark Cuban has finally named his biggest regret from selling the Dallas Mavericks, and it has nothing to do with giving up control of the franchise itself.
Cuban has made clear he does not regret the sale. What still bothers him is who ended up taking over and how the process unfolded after he stepped back.
That makes his latest comment more pointed than it first sounds. It is not nostalgia talking, it is frustration. And the events since 2023 have made that frustration easier to understand.

Mark Cuban admits real regret after selling the Dallas Mavericks
Speaking on the Intersections podcast, Cuban made it clear that the sale itself is not what still bothers him.
“I don’t regret selling. I regret who I sold to. I made a lot of mistakes in the process, and I’ll leave it at that,” Cuban stated.
That line stands out because Cuban had long been the face of the franchise, even after agreeing to sell his majority stake. For him to separate the act of selling from the people he sold to says plenty on its own.
It also invites a bigger question. What exactly has gone so wrong under Patrick Dumont’s ownership group that this regret now feels so sharp?
Patrick Dumont’s era has been defined by damaging Dallas Mavericks decisions
The clearest example remains the Luka Doncic trade. Dallas sent away the face of the franchise for Anthony Davis, Max Christie, and one future first-round pick, a return Cuban himself later suggested was not strong enough.
That decision became even harder to defend when Davis was moved again only a year later. Instead of stabilising the franchise, the trade made the original gamble look even more short-term and chaotic.
The fallout did not stop there. Fan anger spilled into protests, public embarrassment, and in-arena ejections, turning a basketball decision into a full organisational crisis.
Then came another major consequence when Nico Harrison was fired, a move that underlined how badly the post-Luka plan had unravelled.
Viewed together, those decisions help explain Cuban’s comment. His regret is not about leaving, it is about what the Mavericks became after he did.
