"Tech and chip stocks" fall across Asia, Europe, and the US after CEOs of tech giants unanimously call for a slowdown in AI development.

Tech and chip stocks fell across Asia, Europe, and the US after the leaders of Anthropic, OpenAI, and Elon Musk agreed to slow down the development of advanced AI amid security concerns.

On September 14, 2026, at 3:24 PM, CNBC reported that shares of artificial intelligence (AI) companies worldwide fell on Monday after Dario Amodei, CEO of Anthropic, called for a slowdown in the development of AI capabilities and received support from other major tech leaders amid escalating debates about the risks from rapidly evolving AI models.

In Asia, South Korean stock SK Hynix closed down more than 6%, while Samsung Electronics fell more than 4%. SoftBank, a major investor in OpenAI, plunged 10% in Japan.

European markets also faced selling pressure on semiconductor and AI-related stocks. ASML, a manufacturer of industrial chip machinery, fell more than 4%, Nokia dropped around 5%, and Infineon declined by more than 6%. Shares of companies linked to data center expansion, such as Siemens Energy and Schneider Electric, also declined.

On the US stock market, prior to the open trading, shares of memory chip manufacturer Micron were down about 5%, Intel nearly 6%, and Nvidia more than 2% off. Shares of large technology companies investing in AI and data center infrastructure, such as Microsoft, Amazon, and Alphabet, also saw slight declines.

The selling pressure came amid escalating debate over the risks of AI in recent weeks, following the resignation of Jacob Coxon, a researcher at Anthropic who previously worked with OpenAI. Coxon expressed concerns that Anthropic and OpenAI were jeopardizing human safety due to the rapid development of AI.

Subsequently, Evan Hubinger, a security researcher at Anthropic, stated that he estimates there is more than a 10% chance that AI could lead to the deaths of all humans within the next 10 years. This comment sparked intense debate on social media and led to responses from leaders in the AI ​​industry.

Amodei published an article on Saturday urging tech companies to slow down the pace of upgrading AI models to allow time to address potential risks, a proposal that led to a rare consensus among Anthropic's major competitors.

Sam Altman, CEO of OpenAI, stated that he agrees with Amodei that AI companies need to control the pace of development of cutting-edge technology. Meanwhile, Elon Musk, CEO of SpaceX, who has warned of the risks of AI for years, said, "Dario is right."

Investors are concerned that if the AI ​​industry slows down its widespread technological development, it could have a ripple effect on numerous companies, from AI developers and semiconductor manufacturers to businesses involved in data center investments, as it may delay the adoption of AI technology.

Zoe Gillespie, Senior Vice President at RBC Brewin Dolphin , stated that the recent stock market rally has been partly driven by expectations of AI growth and increased productivity. Therefore, if this trend falters, it could impact stock market returns in the near future.

She also stated that current share prices already largely reflect expectations for the future profit growth of these companies. If this growth trend is threatened by a slowdown in AI development, it could create volatility in the stock market.
