Stock market today trading was dominated by a sharp sell-off in artificial intelligence and semiconductor shares after leading technology executives called for a slower pace of AI development. The comments revived concerns that a pause in frontier AI progress could reduce demand for chips, computing power and data-center infrastructure.
The market reaction spread across Asia, Europe and U.S. premarket trading. Investors are now weighing whether a more cautious approach to artificial intelligence could affect the enormous spending plans that have powered the technology rally.
Stock Market Today: AI Shares Face a Powerful Sell-Off
South Korean technology giants led the decline in Asia. SK Hynix shares closed down more than 6%, while Samsung Electronics fell over 4%. SoftBank, one of OpenAI’s major investors, dropped 10% in Japan.
European stocks connected to the AI supply chain also moved sharply lower. ASML, the leading chip equipment manufacturer, declined more than 4%. Nokia fell around 5%, while Infineon dropped more than 6%. Companies involved in data-center construction and power infrastructure, including Siemens Energy and Schneider Electric, also traded lower.
U.S. premarket trading showed similar pressure. Micron declined about 5%, Intel dropped nearly 6% and Nvidia fell more than 2%. Microsoft, Amazon and Alphabet were slightly lower as investors assessed whether slower AI development could eventually affect cloud demand and earnings growth.
- SoftBank fell 10% in Japan.
- SK Hynix declined more than 6%.
- ASML dropped over 4% in Europe.
- Intel lost nearly 6% in U.S. premarket trading.
- Nvidia traded more than 2% lower.
Why AI Leaders Are Calling for a Slowdown
The latest market weakness follows a growing debate about the risks associated with rapidly improving AI models. The discussion intensified after Jacob Coxon, a researcher at Anthropic who previously worked at OpenAI, resigned and expressed concern that leading AI companies were taking dangerous risks.
Anthropic safety researcher Evan Hubinger later said he believed there was a greater than 10% chance that AI could “kill all humans” within the next decade. The comments triggered a fierce online debate and placed renewed attention on AI safety, oversight and corporate responsibility.
Anthropic CEO Dario Amodei responded over the weekend by calling for companies to slow the pace at which they improve the capabilities of frontier AI systems. He did not advocate stopping progress entirely. Instead, Amodei said development should proceed more carefully, with stronger monitoring and safety measures.
Major Technology Figures Back Responsible Progress
Amodei’s proposal received unusual support from leaders of competing technology companies. OpenAI CEO Sam Altman said he agreed that the industry needed to “pace the frontier.” SpaceX CEO Elon Musk, who has warned about AI risks for years, also endorsed Amodei’s position.
Altman later clarified that pacing does not mean stopping. He said AI progress would remain rapid, but that safety cases and monitoring could make the process slower and more expensive.
That distinction is important for investors. A complete halt would represent a major shock to the technology sector, while a measured slowdown could simply delay product launches, model training and some capital expenditures.
What the AI Debate Means for Investors
The recent technology rally has been built on expectations of strong AI-related revenue, rising productivity and enormous investment in computing infrastructure. Hundreds of billions of dollars are being directed toward chips, cloud services, electricity networks and data centers.
Zoe Gillespie, senior director at RBC Brewin Dolphin, told CNBC’s “Squawk Box Europe” that much of the equity market’s future earnings growth is tied to AI expansion. If those expectations weaken, she said, the change could destabilize stock performance.
However, not every analyst expects a prolonged collapse. Ben Barringer, global head of technology research at Quilter Cheviot, said the pace of change could slow while remaining extremely significant. He added that demand for inference—the process of running AI models—continues to exceed supply.
That means chipmakers and cloud providers could still benefit even if training and rollout schedules become more cautious. For now, the stock market today reflects uncertainty rather than a confirmed breakdown in AI demand. Investors will likely focus on company guidance, data-center spending and signs of whether safety requirements materially change capital plans.
Frequently Asked Questions
Why are AI stocks falling today?
AI stocks are falling after Anthropic CEO Dario Amodei and other technology leaders supported a slower, safer pace of artificial intelligence development. Investors fear this could reduce chip demand and delay spending.
Which companies were hit hardest?
SoftBank, SK Hynix, ASML, Micron and Intel recorded some of the sharpest declines. Nvidia also traded lower in U.S. premarket activity.
Does a slowdown mean AI development will stop?
No. Amodei and Sam Altman described the proposal as a slower pace of progress, not a complete halt. Development is expected to continue with greater attention to monitoring and safety.
What is inference in artificial intelligence?
Inference is the process of running an AI model to produce an answer or result. It differs from training, which uses large amounts of data to improve the model.
