Billionaire Mark Cuban flatly shut down any chance of backing Kamala Harris for another White House run – and revealed he might throw his support behind a Republican candidate.
The celebrity entrepreneur, who served as a high-profile surrogate during Vice President Harris’ failed 2024 presidential campaign, declared Tuesday that he has “no” interest in seeing the Democrat run for president again at Politico’s Health Care Summit.
His comments came just weeks after the former veep teased a possible 2028 comeback.
When pressed on why he won’t support Harris again, Cuban quickly shot back: “It doesn’t matter.”
“I don’t care at this point in time,” the Dallas Mavericks minority owner stressed to Politico senior executive editor Alex Burns.
“Right now, we’ve got until 2028. I don’t care who the candidates are, I’m not trying to pick a candidate, I’m not trying to promote a candidate. I’m trying to change how f—ked up this health care industry is right now. That’s all I care about.”
The former “Shark Tank” judge actively campaigned for Harris on the trail and previously revealed she once considered him a potential running mate before shutting her down.
But Cuban – a strong advocate for health care reform – fired off another blunt response when Burns grilled him over what he remembers of the former VP’s health care policies.
“Don’t remember, don’t care, those days are gone,” he urged.
“I don’t care. There’s no reason to re-litigate that. It doesn’t matter.”

Cuban praised President Trump and his health department for pushing to slash drug prices and fast-truck drug trials — and even admitted he would consider backing a Republican who shares his reform goals, depending on “what’s best for the country.”
“I’m not an ideologue about parties,” Cuban said, adding, “Get rid of both parties, I’m happier.”
Earlier this month, Harris told Rev. Al Sharpton she was “thinking about” another run for president during an on-stage interview at his National Action Network conference in New York City.
Other Democrats eyeing possible White House runs also took the stage at the conference, including Illinois Gov. JB Pritzker, Maryland Gov. Wes Moore and former Transportation Secretary Pete Buttigieg.
