AI-linked shares slide after Anthropic chief calls for slower progress
Pre-market declines across semiconductor and AI infrastructure stocks followed Dario Amodei’s warning that safety measures must keep pace with advances in AI capabilities.
AI-linked shares fell in pre-market trading after Anthropic chief executive Dario Amodei called for a slower pace of artificial intelligence development, arguing that safety measures need time to keep up with advances in model capabilities.
Yahoo Finance reported declines of about 7% for Marvell and SK Hynix. CoreWeave, SanDisk, Intel and AMD were down about 6%, while Micron and Super Micro fell 5%. Nvidia and Broadcom declined about 3%.
Amodei made the case for greater prudence in a 3,800-word essay published on Saturday. OpenAI chief executive Sam Altman endorsed the warning, identifying loss of human control and excessive concentration of power as risks that the industry must avoid.
The proposals focus on security measures, independent review, safety standards and international co-operation, according to Bernstein analyst Madison Rezaei. Rezaei said they did not amount to an immediate call to reduce capital expenditure or halt model training, although investors were increasingly considering the consequences of slower training.
CoreWeave was identified as particularly exposed to any slowdown in AI training. Rezaei said a pullback could affect demand for the company’s contracted but not-yet-sold rural power capacity. Its existing backlog is primarily covered by take-or-pay contracts, which Rezaei said should limit the threat to that business.
