Mark Cuban says there’s “no chance” he’s trying to campaign his way into the White House … following speculation he might run for President in 2024 after selling a majority stake in the NBA’s Dallas Mavericks.

Comments of the supposed political move flooded in on X … though the billionaire tells TMZ that a presidential campaign trail for next year was “galaxies off” and adding, “family would disown me.”

Remember … after years of building his empire, Mark is putting family first — announcing on the Showtime podcast “All The Smoke” Monday he was leaving “Shark Tank” after 16 seasons as it conflicts with his personal time.

And of course … becoming President — arguably the busiest job in the world — wouldn’t do a whole lot to clear up his schedule.

However, he’s entertained the idea before, divulging to Harvey on “OBJECTified” in 2017 that he’d run as a Republican to challenge Donald Trump. In 2019, Mark told us his family “voted down” his serious desire to run for President in 2020.

The renewed political chat gained traction after TMZ Sports confirmed Mark was selling his majority stake, reportedly valued at $3.5B, to Miriam Adelson … getting a massive return on the investment after buying the team in 2000 for $285 million.

He’ll retain some shares and be the lead decision-maker when it comes to basketball ops — but billionaire widow/heiress Adelson has some plans of her own for the Mavs … mainly building a new arena and casino — if a gambling bill passes in Texas.
