President Donald Trump swung from celebration to blame within 24 hours after the stock market dropped sharply on Thursday, prompting a wave of criticism from users on X.

After claiming credit for a market high on Wednesday, Trump pointed the finger at Democrats in a post on his Truth Social platform, saying the market "suffered" because "Dumocrats" swept Republicans out of their majorities in both the House and the Senate.

"Such a sad thing to watch!" Trump said. "It took us so much work to get us to a level that no one has ever seen before, and then this."

"Your 401(k)s have, therefore, dropped. Remember, it wasn't Republicans, it was Dumocrats," the president said, using his nickname for his opponents.

In another post, Trump blamed American voters for the plunge rather than an impending AI bubble, writing: "The Stock Market crashed today because the Dumocrats had a big Tuesday — So sad to see, you only have yourselves to blame! President DONALD J. Trump."

The White House's X account reposted the most heated of Trump's messages, and critics quickly seized on what they viewed as insincerity: the president praising himself for the market one day, then blaming Democrats for its fall the next.

The reversal reflects a long-running pattern in American politics: administrations of both parties have claimed credit for market highs and absorbed blame when markets fall. Because 401(k) retirement accounts rise and fall with the stock market, sharp swings reach directly into household savings — which is why Trump's back-to-back messages drew such pointed responses.

"The level of stupidity is simply staggering," wrote one critic beneath the White House's account. "Just one day apart. This man is not fit to be president."

Critics were also quick to quote Trump's remarks from the previous day, when he declared: "The Stock Market just hit another Record High – 91 Days in just a short period of time—less than two years. Your 401(k)s are through the roof. Record Setting All!"

"This is why Americans hate Trump," said another user on X. "All you do is lie. Today's sell off was about AI stocks tanking. Yesterday, following the results of the Democrat tsunami the market was up over 1000 points."

A third critic accused the president of never "taking responsibility."

"It's always someone else's fault," the user said. "If you hadn't dragged us into another war in the Middle East, wrecked affordability, and covered up for [criminals], we wouldn't be talking about a stock market drop. This has nothing to do with Democrats and everything to do with your failed agenda."

According to a Bloomberg report, the slide in equities accelerated on Thursday amid concerns that the new Congress could tighten oversight of the AI industry, including the construction of data centers. Chip giants and other technology stocks suffered heavy losses as a result.

Data centers — the facilities that house the servers and chips used to train and run AI systems — have become the physical backbone of the industry's expansion, which is why their regulation sits at the center of the debate over how, or whether, AI should be supervised. Any move by the new Congress on that front would land directly on the chipmakers and technology companies that absorbed Thursday's heaviest losses.

Critics maintain, however, that the AI industry remains largely unregulated and in need of supervision.
