Tech’s worst week since April shows the AI boom may be breaking

Technology stocks fell on Friday, amid fears of an AI bubble, a further drawn out federal government shutdown, and economic data that suggests consumer sentiment has fallen toward record-low levels.

That’s in addition to economic data that showed last month’s layoffs hit their highest level for October—in 20 years. That report, from global outplacement firm Challenger, Gray & Christmas, also also said hiring slowed to lowest point in 14 years.

Despite strong third-quarter earnings reports, the tech-heavy Nasdaq Composite Index (^IXIC) was down once again, for the second consecutive day, about 1% in afternoon trading on Friday, as big Tech Stocks tumbled, closing out the week as the Index heads toward what could be its worst week since April, when the Trump Administration introduced its “Liberation Day” tariffs.

Chip stock Arm Holdings plc (ARM) was down 4%, while Advanced Micro Devices, Inc. (AMD) fell 3%, and Al chip designer Nvidia (NVDA) was down 1%, at the time of this writing in afternoon trading, as investors worry about high valuations, and mass layoffs in the name of artificial intelligence (AI). Tesla (TSLA) was also down some 3%.

Among those sounding alarm bells is hedge fund investor Michael Burry, who runs Scion Asset Management, and is betting against both betting against both Nvidia and Palantir. According to his Securities and Exchange Commission filings, Scion bought an estimated $187.6 million in puts on Nvidia, and another $912 million on Palantir, as CNN reported. Burry has warned both companies are overvalued. (Burry famously predicted the 2008 housing market collapse, and was made famous by the 2015 film The Big Short.)

Last week Burry posted on X, “Sometimes, we see bubbles. Sometimes, there is something to do about it. Sometimes, the only winning move is not to play,” in what some think is his way of saying there is an AI bubble.
