Billionaire Mark Cuban Embarrasses Himself With Stock Market Advice — Deletes Post After Backlash as Wall Street Bleeds

In a stunning display of mixed messaging, billionaire entrepreneur and “Shark Tank” star Mark Cuban has found himself at the center of controversy after telling investors not to panic during the latest stock market meltdown — only to backtrack and delete his comments hours later.

As markets reeled from their worst weekly losses since the dark days of 2020, Cuban took to X (formerly Twitter) on Sunday night with bold — some would say reckless — advice: “Don’t sell.

It will come back. I just don’t know how long it will take.”

But the bravado didn’t last.

Shortly after financial news outlet Watcher.Guru — with nearly 3 million followers — blasted screenshots of Cuban’s now-deleted post across social media, the billionaire quietly walked back his statement.

“As some others rightfully mentioned, no one knows. You have to look at your own circumstances and talk to those whose advice you value,” Cuban sheepishly posted in a follow-up message.

Cuban’s public flip-flop comes at a time of extraordinary market volatility, triggered by former President Donald Trump’s shocking announcement of sweeping tariffs on U.S. trading partners.

The S&P 500 cratered 10% in just two days, while the Nasdaq 100 officially entered bear market territory for the first time since 2022.

Markets plunged again on Monday, with Europe and Asia following the U.S. into the red.

Investors, already on edge, saw Cuban’s contradictory posts as emblematic of a billionaire class hopelessly disconnected from everyday financial realities.

But Cuban didn’t stop there.

In a series of blistering posts on Bluesky over the weekend, the Dallas Mavericks owner warned that Trump’s aggressive tariff war, combined with widespread DOGE (Department of Government Efficiency) spending cuts and layoffs, could spark an economic collapse worse than the Great Recession of 2008.

“If the new tariffs stay in place for multiple years, and are enforced and inflationary, and DOGE continues to cut and fire, we will be in a far worse situation than 2008,” Cuban declared.

For context, the 2008 financial crisis saw U.S. GDP contract by over 4%, unemployment surge to 10%, and the housing market implode — a catastrophic sequence of events that reshaped the global economy.

Former President Trump, never one to shy away from controversy, acknowledged the market pain but dismissed concerns as weakness.

“ONLY THE WEAK WILL FAIL!” Trump roared in a Friday post on Truth Social, suggesting that real Americans would weather the storm.

As Cuban’s credibility takes a hit, financial analysts are left wondering: Was this the billionaire’s unfiltered honesty — or just another case of Silicon Valley hubris colliding with Main Street reality?

Either way, one thing is clear — investors looking for steady guidance during this storm won’t be turning to Mark Cuban anytime soon.
