AI Slowdown Fears Send Nvidia and Chip Stocks Lower
Several important AI companies warned that advanced artificial intelligence may be developing too quickly.
They said companies should slow down enough to study the risks and add safety checks.
Investors became worried that slower AI development could mean less spending on AI equipment and services.
As a result, shares of Nvidia, Intel and other chip companies fell.
The broader US stock market also moved lower.
The reports gave different numbers because some described prices at different points during the trading day.
Dario Amodei of Anthropic made the slowdown proposal.
Sam Altman of OpenAI supported it, while Elon Musk also said Amodei was right.
China disagreed with the idea, calling such concerns fearmongering.
US stocks fell on Monday after AI leaders urged a slower pace of advanced AI development.
Nvidia, Intel, AMD, Broadcom, Marvell Technology and CoreWeave traded lower, with reported declines varying during the session.
The Nasdaq fell between 1.05% and 1.7% in the reports, while the S&P 500 and Dow also declined.
Anthropic CEO Dario Amodei cited potential AI risks and called for stronger safeguards and a coordinated slowdown.
China rejected calls to slow AI development, while OpenAI CEO Sam Altman backed the proposal and postponed a possible IPO.
