Chip stocks slide after AI executives urge slower development pace

Semiconductor shares fell sharply on Monday after several prominent artificial intelligence executives called over the weekend for a slower pace of frontier AI development, triggering a broad selloff in chip stocks and dragging down the Nasdaq.

AMD Advanced Micro Devices, Inc. ↗ 2.70% dropped roughly 6%, Intel ↘ 0.18% fell about 7%, Micron ↗ 3.92% declined more than 6%, and Nvidia ↗ 1.34% pulled back around 3%, with the iShares Semiconductor ETF ↗ 2.69% falling 6% against a 2% decline in the Invesco QQQ Trust ↗ 0.63%, confirming the selling was concentrated in chips rather than spread across the broader tech sector.247wallst+1

A Weekend Letter Rattles Markets

The catalyst was a 4,000-word open letter published Saturday by Anthropic CEO Dario Amodei titled "We Must Pace the Frontier," in which he argued that AI capabilities are advancing faster than labs can manage the risks. He proposed a framework calling for independent evaluators with access to AI labs, coordinated safety standards, and greater international cooperation.fastcompany+1

The letter was swiftly endorsed by OpenAI CEO Sam Altman, who posted on X, "I agree with Dario," and by Elon Musk. Microsoft ↘ 0.80% CEO Satya Nadella wrote on LinkedIn that "any pursuit of superintelligence has to be grounded in the core principle that if the AI we build is not helping humanity and under human control, it's not worth pursuing".gurufocus+1

President Donald Trump dismissed the calls, saying the U.S. is leading China and that "whoever wins AI wins".stocktwits

Positioning Unwind, Not Demand Shift

The order of the declines pointed to a positioning unwind rather than a fundamental reassessment of AI demand. Intel, with the least direct exposure to AI accelerators, fell the hardest, while Nvidia, the most exposed, fell the least — the reverse of what a genuine demand downgrade would produce. Amodei explicitly ruled out halting training, and Anthropic itself committed to deploying AMD's MI450 GPUs in a disclosed partnership.247wallst

Meanwhile, software stocks rose. ServiceNow ↘ 2.17% climbed nearly 5% in premarket, while Adobe ↘ 1.48% and Meta ↘ 2.43% also gained, as investors rotated from suppliers of AI capacity toward applications built on top of it.techi

Oil and Rates Add Pressure

The chip selloff did not arrive in isolation. Brent crude surged above $108 after Saudi Arabia's East-West pipeline was knocked out by a drone attack and is expected to remain mostly offline for three to five weeks, according to the Associated Press. CME FedWatch showed traders pricing a nearly 89% chance of a Federal Reserve rate increase at its meeting Wednesday, adding further pressure on high-growth, premium-valued equities.techi+1

"This is probably more of a hiccup for AI stocks as opposed to an eye-opener," Dennis Dick of Triple D Trading told Reuters. The tape suggested otherwise: a hiccup does not usually take Intel down 7% and lift ServiceNow 5% in the same session.techi
