Anthropic called for a slower pace of frontier AI model development over the weekend, triggering a sharp overnight slide in semiconductor stocks globally. Major chipmakers including Intel, AMD, and Micron dropped alongside Asian suppliers like SK Hynix, as investors weighed potential earnings impacts against the multi-billion-dollar infrastructure boom.
AI executives’ calls to slow development of the technology are likely to weigh on chipmaker and supply-chain stocks in the near term, but will probably have limited long-term impact as spending on computing infrastructure remains strong, market watchers say. Semiconductor makers and other artificial intelligence-linked stocks may bear the brunt of any initial selloff on Monday, while investors assess whether a more cautious approach to developing advanced models will crimp earnings. Still, with demand for chips, energy and computing power continuing to outstrip supply, any weakness may prove short-lived.
Anthropic Pushes for Pacing and Independent Safety Testing
The push for restraint emerged from a weekend announcement by Anthropic Chief Executive Officer Dario Amodei. He urged frontier artificial intelligence companies to slow the pace of model capability development. Amodei argued that artificial intelligence is advancing faster than companies can reliably manage its risks.
The proposal urged frontier AI labs to prioritize independent safety testing and deliberate pacing. Specifically, Amodei outlined a three-part framework. It calls for permanent independent evaluators with employee-like access to AI labs, coordination among leading companies on safety standards, and greater international cooperation. Amodei stressed that he is not calling for a halt to AI training or technical progress, but for companies to create more time to test and safeguard increasingly capable models.
The call comes as a growing public debate over AI safety has intensified following reports of AI agents being used for hacking, fraud, surveillance and other potentially harmful activities. At the same time, the push faces a major tension: AI companies have enormous financial and competitive incentives to keep moving quickly, particularly as OpenAI and Anthropic prepare for potential IPOs.
Dario is right.
OpenAI Chief Executive Officer Sam Altman supported the plan, while xAI’s Elon Musk endorsed the warning. The public alignment among major players highlights growing internal anxieties over potential misuse, including cyberattacks, surveillance, and automated fraud.
Chip Stocks and Global Markets Bear the Brunt of Overnight Sell-Offs
Financial markets reacted swiftly to the safety warnings. Shares of major semiconductor firms slid in overnight trading late Sunday as traders assessed whether a cautious development approach would crimp future hardware demand.
Losses hit American and Asian markets alike. Intel and Advanced Micro Devices stocks fell more than 4%, while memory chip firms Micron and SanDisk dropped 3.9% and 4.5%, respectively. Specialized exchange-traded funds felt the pinch too. The iShares Semiconductor ETF (SOXX) fell 2.8%, and the Roundhill Memory ETF (DRAM) declined 5%.
Asian supply chains faced immediate pressure. Shares of Samsung Electronics dropped 3.8% in Seoul on Monday, while those of SK Hynix dropped over 5%, dragging South Korea’s benchmark index KOSPI down 3.6%.
Market Watchers See Long-Term Infrastructure Trade Staying Intact
Despite the immediate market friction, many financial strategists argue that the sell-off will prove temporary. Chipmakers have been among the biggest beneficiaries of the AI boom, as hyperscalers and AI developers have poured billions of dollars into GPUs, custom accelerators and high-bandwidth memory needed to build out data-center infrastructure.
Concerns over the vast sums being poured into AI have weighed on technology stocks as investors question whether earnings can justify soaring infrastructure costs. The scrutiny has left high-valuation shares linked to the technology particularly vulnerable, with signs of increased spending or weaker returns triggering selloffs. The tech-heavy Nasdaq 100 Stock index has dropped more than 4% from the record notched in June, while a gauge of chip shares in the US has slumped 14% and Asian tech stocks have slid almost 8%. The benchmark S&P 500 Index and MSCI’s gauge of global shares have both edged up about 0.6% in the period.
Institutional investors share a similar view. Gary Tan, a portfolio manager at Allspring Global Investments in Singapore, noted that the developments are unlikely to derail the longer-term AI trade.
It may cause some short-term pressure, but it’s unlikely to derail the longer-term AI trade. AI development is still at a relatively early stage, and I’m not sure the rest of the ecosystem is willing to accept the current pecking order and slow down while the technology continues to evolve so rapidly.
The three CEOs agreeing to pace things does not really change the money being spent on chips, power and infrastructure. In fact, it extends the development timeline.

Billy Leung, an investment strategist at Global X Management in Sydney, pointed out that pacing model rollouts simply extends the development timeline rather than erasing the capital being poured into power, chips, and physical data centers.
