"If I was single, I'd definitely be running," he said.
Cuban said he was "seriously considering" running, hinting that maybe he'll run as an independent.
"I don't know," Cuban said. "I'm for smaller government ... I think there is a healthcare solution."
Recently, he said in an interview with former Democratic South Carolina state Rep. Bakari Sellers on Sellers' podcast ViewPoint, Cuban said he was "seriously considering" a run for the White House.
"Considering, yes," Cuban said. "Ready to commit to it, no."
Later the same day, in an interview with CNBC, Cuban said he is "actively considering" a presidential bid, though he added there's a 90% chance he will not run.
"Based off what's happening in the White House, based off what's happening in the country and the world, we need better leadership," Cuban said. "And I think I could do a better job. But there's a lot more to it than just thinking you can do a better job and so, I'm not ready to make the commitment."
"It's not my all-time dream to be president of the United States," he added.
Cuban is often sharply critical of President Donald Trump, and the billionaire mogul supported Democratic presidential nominee Hillary Clinton during the 2016 general election campaign. However, he expressed openness to Trump's candidacy during the Republican primary.
Recently, Cuban criticized Trump's controversial comments aimed at NFL and NBA players, offered up his thoughts on the Republican tax reform proposal, and has assisted in Puerto Rico hurricane recovery efforts.
An August poll showed Cuban leading Trump in a prospective 2020 race. The poll, from the left-leaning polling firm Public Policy Polling, showed Cuban, running as the Democratic presidential nominee, with a small edge over Trump.
"These are always entertaining," Cuban told Business Insider in an email at the time. "As I have said before, I would only run if I can come up with solutions for healthcare, the plight of working families, and reducing the stress levels of our country. It's possible. When I have something to offer, I will."
