Key points

  • Nasdaq 100 futures fell 1.6% before Monday's U.S. session as investors reassessed the pace of AI development and spending.
  • SoftBank dropped as much as 13.2%, while major semiconductor shares declined across Japan, Taiwan and South Korea.
  • The warnings do not amount to an industrywide halt, and market moves also reflected oil, interest-rate and geopolitical pressures.

Technology shares came under broad pressure on Monday after senior executives at leading U.S. artificial-intelligence companies called for a slower, more controlled pace of model development. Nasdaq 100 futures fell 1.6% before the U.S. session, while semiconductor and AI-linked stocks declined across Asia and Europe. The reaction showed that investors are treating the speed of technical progress as a financial variable, not only a policy debate.

A safety proposal becomes a market event

The immediate catalyst was an essay by Anthropic Chief Executive Dario Amodei proposing that frontier laboratories pace capability gains so safety work can catch up. He said the approach should begin with independent evaluators receiving ongoing access to company systems and processes, followed by coordination among democratic countries and, eventually, broader international cooperation. Amodei stressed that pacing would not mean ending model training or technical progress.

OpenAI Chief Executive Sam Altman and xAI leader Elon Musk publicly supported the call, according to Reuters. Altman separately said OpenAI would not pursue an initial public offering this year because of safety concerns. That IPO decision was already known over the weekend; Monday's fresh development was the scale of the market response as trading opened in Asia and moved toward the U.S. session.

Chip and AI exposure takes the biggest hit

Reuters reported that Nasdaq e-mini futures were down 1.3% during Asian hours, while later Barron's data showed Nasdaq 100 futures down 1.6%, compared with a 0.7% decline in S&P 500 futures and a 0.2% drop in Dow futures. The widening gap indicated that investors were concentrating their selling in technology companies most exposed to AI investment expectations.

SoftBank, a major OpenAI investor, fell as much as 13.2% in Tokyo. Memory-chip producer Kioxia initially lost 9.8%, Tokyo Electron declined 3.7%, Taiwan Semiconductor Manufacturing slipped 1.2%, SK Hynix dropped 5.3% and Samsung Electronics fell 3.7%. Those moves crossed several markets and parts of the supply chain, from memory and fabrication to equipment and venture exposure.

Why the warning matters to investors

AI-linked valuations have been supported by expectations of sustained demand for processors, memory, data centers and electricity. A slower cadence could delay revenue growth or extend the time needed to earn a return on large infrastructure commitments. It could also shift spending toward testing, security and compliance. None of those outcomes is certain, but even a modest change in the expected development curve can matter when share prices assume rapid expansion.

The selloff should not be read as evidence that the companies have agreed to a binding industrywide pause. Amodei's plan includes a unilateral commitment by Anthropic to embedded outside evaluators, but its broader coordination steps would require other companies and governments. Investors also faced higher oil prices, elevated bond yields and Middle East tensions, so the AI warnings were an important catalyst rather than the only source of risk aversion.

What comes next

U.S. trading will test whether the early decline persists once cash markets open and investors hear more from chipmakers, cloud providers and AI laboratories. The central question is whether safety-driven pacing changes capital expenditure, product schedules or demand for computing capacity. Until companies provide concrete timelines, Monday's move reflects a repricing of expectations rather than confirmed cuts to investment or output.
