Mark Cuban is feeling the sting of seller's remorse, and it's a doozy. The former Dallas Mavericks majority owner has openly admitted he'd buy the team back if he could—but that ship may have sailed for good.

In December 2023, Cuban sold 72.3% of the franchise to the Adelson and Dumont families for a staggering $3.5 billion. At the time, he cited estate planning and the financial strain of competing in the NBA as a self-described "middle-class billionaire." But now, with the Luka Doncic trade fresh in everyone's memory, Cuban's tone has shifted dramatically.

"If there was any chance of being able to do that anymore, I would," Cuban told Front Office Sports. It's a candid admission from a man who spent 23 years as the face of the Mavericks.

But did he actually try to reclaim the team? The answer is complicated. Cuban revealed that while he didn't initiate the effort, a group of unhappy parties approached him about buying back the franchise. "I was like, look, if you can get them to sell, I'll be more than happy to contribute my equity," he explained.

Unfortunately for Cuban—and Mavs fans who miss his energetic presence—the Adelsons aren't budging. The effort "didn't materialize," and the current owners have no interest in selling. Adding fuel to the fire, Cuban has hinted at maybe buying a warm-weather NBA franchise in the future. Could a Miami or Phoenix team be in his sights? Only time will tell.

For now, Cuban's regret serves as a cautionary tale in the high-stakes world of NBA ownership. And for fans, it's a reminder that even billionaires can't always get what they want.
