Mark Cuban, the billionaire business mogul and “Shark Tank” star, quashed speculation he will be making a White House run in 2028 — even as he has become a prominent voice against Donald Trump’s agenda in Washington.

The Dallas Mavericks minority owner was asked if his name would be on a ballot in the near future at the Principles First convention, a gathering of conservatives who feel politically homeless in Trump’s MAGA-fied version of the party.

“Hell no. It’s not going to happen,” Cuban said, before joking to the crowd gathered at the JW Marriott in Washington, D.C., roughly three blocks from the White House, then quipped: “Okay, if y’all write in and I don’t have [a campaign].”

“No, I don’t want to be President. I’d rather fuck up health care,” a nod to the Cost Plus drug company he recently launched.

Cuban has teased a presidential run in the past, exploring running as an Independent in 2020 and hiring a pollster to assess his prospects. He ultimately decided against it and threw his support behind Joe Biden. Some recent polling has even included his name in a list of 2028 candidates that had him notching some support in a crowded field.

Cuban served as a surrogate for Vice President Kamala Harris’ presidential campaign and stumped for her in key swing states like Nevada and Wisconsin.

“I mean, it’s kind of fun, actually,” Cuban said. “I learned that the Democrats can’t sell shit.”

He later added that if Democrats want to learn how to sell their ideas to the American public, they should look to Trump as an example.

“It doesn’t mean … he can execute on that,” Cuban added. “Right now, he’s still in the salesmanship stage, and I think now people are starting to ask, alright, it’s great to sell it now, can you execute on it.”

Cuban doesn’t believe Trump will actually deliver on his litany of campaign promises, and that should be a boon for Democrats — if they can effectively make the case. He criticized Democrats for being “too reflexive” to Trump’s whims — a tactic they tried in 2024 when Harris emphasized Trump as a threat to democracy.

“I think there’s too much reflexology. ‘Trump sucks,’” Cuban said. “How’d that work in the campaign? It didn’t.”
