Summary
Shares in the semiconductor designer Nvidia, the world’s most valuable company, were down 3.3% by market closing in New York City, while Advanced Micro Devices (AMD) slid 4% and Micron Technology and Sandisk shares slumped by 5%. The sell-off came after the chief executive of Anthropic, Dario Amodei, appealed at the weekend for the AI industry to “slow down”. However, Donald Trump dismissed calls to increase controls on AI as a “sick conspiracy”. In a social media post on Monday, the president wrote: “The only control or ‘guardrails’ that AI needs is a STRONG AND SMART (High IQ!) PRESIDENT, and the USA has that, in spades!”
