Chip shares fell across three continents on Monday after leading AI developers asked the industry to slow down, turning a safety argument into a spending question for everyone selling silicon into data centers.
In a weekend essay, Anthropic chief executive Dario Amodei called rapid buildout reckless and warned that agent swarms could cause hundreds of billions of dollars in harm. OpenAI’s Sam Altman, Google DeepMind chair Demis Hassabis and Elon Musk backed the appeal. Altman told Fortune an IPO this year would be ill advised given the safety debate.
Marvell shed nearly 8 percent, with Intel, Micron and SanDisk each down roughly 6 percent. Broadcom lost 3.9 percent and Nvidia 2.5 percent, with Nasdaq futures down 1.6 percent.
Europe was hit harder. ASML slid 6 percent, on track to shed roughly €33.6B in market value. ASM International fell 10 percent, BE Semiconductor 8.2 percent, Infineon 8.3 percent and STMicroelectronics 6.2 percent.
In Asia, SoftBank closed 11 percent lower, Kioxia lost 6.4 percent and TSMC slipped 1.2 percent. US President Donald Trump dismissed talk of AI guardrails, arguing that China gains from any slowdown.
