In a twist that even Shark Tank viewers couldn’t have seen coming, billionaire entrepreneur Mark Cuban’s net worth reportedly dropped by a staggering $1 billion mere hours after endorsing Vice President Kamala Harris for the presidency.

Cuban, who has built his brand on savvy investments and unapologetic opinions, now finds himself at the center of a financial storm that seems to be unfolding faster than a bear market.

“It was almost immediate,” said a Wall Street analyst, shaking his head in disbelief. “He was fine, perfectly stable at $5.1 billion. Then, boom—he endorses Harris, and now he’s at $4 billion. You can’t make this stuff up.”

Cuban’s endorsement came as a surprise to some, but others saw it as a natural move for the Mavericks owner, who has become a vocal critic of former President Donald Trump and his economic policies.

During an interview, Cuban praised Harris for her knowledge of technology and her commitment to small businesses. “She understands technology, particularly AI, and she’s committed to reducing healthcare costs in a way that’s actually sustainable for small businesses,” Cuban said. He went on to criticize Trump’s tariffs, calling them detrimental to American companies.

But while Cuban’s endorsement might have earned nods from tech enthusiasts and small business owners, it seems to have come with a steep price tag. According to financial insiders, his endorsement sparked a chain reaction of divestment, with investors fearing that Cuban’s shift in political allegiance signaled a departure from his usual business-first approach.

“People expect Mark to be, well, Mark—unpredictable but generally money-minded,” said a source close to the matter. “This endorsement caught a lot of his investors off guard. Some of them saw it as a signal that maybe he’s becoming more ideological than financial, and that spooked them.”

As news of Cuban’s endorsement spread, so did the fallout. Within hours, investors reportedly began pulling their stakes in Cuban’s various ventures. Some even took to social media to air their grievances, with one investor tweeting, “I trusted Mark Cuban to back strong business principles, not candidates! Politics is poison to portfolios!”

For years, Cuban’s financial moves have been closely watched and often emulated by aspiring entrepreneurs and investors. But in the wake of his Harris endorsement, it seems that some fans felt betrayed, almost as though he’d sold out his commitment to the bottom line. Within a day, shares in some of Cuban’s companies saw noticeable dips as wary investors scrambled to cut their losses.

“It’s like he’s gone rogue,” one investor lamented on a financial news forum. “First, he’s telling us tariffs are bad for business—which, fine, we get it. But then he endorses a candidate, and that’s where we draw the line. You can mess with the market, but you don’t mess with our money.”

As Cuban’s net worth began to shrink, Twitter and X were ablaze with comments from people alternately amused and horrified by the unfolding drama. Hashtags like #BrokeCuban and #MarkTheMarket quickly trended, as social media users shared memes of Cuban’s face on a plunging stock graph and cheeky slogans like, “Mark Cuban: Billionaire Today, Millionaire Tomorrow.”

Some social media users took the opportunity to poke fun at the idea that a billionaire could lose $1 billion for simply making a political statement. “Guess he found out politics and portfolios don’t mix,” joked one Twitter user, adding, “Maybe he should go on Shark Tank and pitch a recovery plan to himself.”

Meanwhile, supporters of Harris rallied to Cuban’s defense, suggesting that his endorsement was brave and indicative of his long-term vision. “He’s betting on the future, not just the bottom line!” one fan posted. Others, however, were less forgiving, with one user writing, “If I wanted advice on who to vote for, I wouldn’t ask a Shark Tank guy. Stick to investing, Cuban.”
