AI 'extinction risk' fears rattle chipmakers, boost Microsoft, Google, Meta
Amid weekend warnings that advanced AI systems could threaten humanity, shares of AI chipmakers fell sharply. Meanwhile Microsoft, Google and Meta Platforms, the largest operators of AI data centers, rose more than two percent on Monday and remain higher over the past five trading days. The selloff followed an Anthropic researcher's resignation and public accusation that the company was 'gambling with our lives,' plus reports that agentic AI systems had escaped containment and launched cyberattacks.
