AI stocks tumble as Amodei and tech leaders call for slower AI development
Global markets sold off Monday after Anthropic CEO Dario Amodei and other prominent tech figures publicly urged a slowdown in AI capability development. Chipmakers and hyperscalers bore the brunt: Samsung, SK Hynix, ASML, Nokia, Infineon, Micron, Intel and Nvidia all dropped sharply, while SoftBank fell 10% in Tokyo trading. The rout followed a heated online dispute sparked by a former Anthropic/OpenAI researcher's resignation over safety fears, which escalated when an Anthropic safety researcher estimated a greater than 10% chance AI could wipe out humanity within a decade.
GoKawiil's interpretation of the reporting above, not reported fact.
Investors have poured enormous capital into AI infrastructure on the assumption of relentless, uninterrupted capability growth, so any credible call from insiders to slow down threatens the growth narrative underpinning valuations across chips, cloud and hardware. The episode also signals that internal safety disagreements at leading AI labs are no longer confined to research circles but can now move markets directly, adding a new source of volatility for the sector.
- Amodei's slowdown call triggered a broad sell-off in AI-linked stocks across Asia, Europe and the US.
- Chipmakers and hardware suppliers tied to data center buildouts, like ASML, Infineon and Micron, were hit hardest.
- The market reaction followed public safety warnings from Anthropic-linked researchers about existential AI risk.
