Nasdaq 100 futures dropped roughly 510 points, or 1.7%, to trade near 29,170 in the predawn hours Monday, while S&P 500 contracts slipped about 0.7%. The move followed weekend commentary from the heads of the two most prominent private AI labs arguing that the industry should deliberately decelerate the pace of model development, a stance that, if taken seriously, threatens the revenue assumptions underpinning the semiconductor rally.
The catalyst was a Saturday essay
Anthropic chief executive Dario Amodei published a long-form post on X outlining a three-part plan to "pace the frontier," committing his company to the first step: granting third-party evaluators permanent, employee-level access to its systems. Hours later, OpenAI's Sam Altman echoed the sentiment in a thread of his own, framing the debate as a choice between two existential risks, loss of human control over advanced systems, or excessive concentration of power in a single lab or nation. Altman also confirmed OpenAI would not pursue a public listing in 2026, citing safety considerations.
Markets from Seoul to Tokyo reacted
SoftBank, OpenAI's largest strategic backer, saw its Tokyo-listed shares fall as much as 13%. South Korea's Kospi, heavily weighted toward the memory-chip supply chain, tumbled more than 3%, while the Nikkei 225 declined roughly 1%. The selloff reflects a simple calculus: equity valuations across the AI complex have been priced for uninterrupted, exponential progress. Any signal that the trajectory might be voluntarily bent downward invites profit-taking.
A contrarian reading from Michael Burry
The investor known for anticipating the 2008 housing collapse offered a sharper interpretation. In his own X posts, Burry argued the slowdown rhetoric is self-serving: large language models are not true artificial intelligence and will not become artificial general intelligence, he wrote, while competition is advancing rapidly, meaning a pause benefits incumbents. He characterized the "we are so awesome it could become dangerous" narrative as hype designed to support forthcoming initial public offerings, noting Anthropic's listing appears to be approaching. OpenAI's decision to delay its own debut, he suggested, masks a deceleration in fundamental growth that executives cannot otherwise explain.
What strategists are watching
Charu Chanana, chief investment strategist at Saxo Bank in Singapore, told Reuters the warnings could weigh on AI and chip shares in the near term. She noted that current valuations embed both robust demand and a relentless pace of technological improvement; when expectations sit that high, even the prospect of a delay can trigger selling. The broader point, she added, is that transformative technology does not guarantee every dollar deployed today will earn an adequate return.
