Stock futures fell sharply on Monday morning, led by significant declines in technology shares, after leading artificial intelligence CEOs publicly called for a slowdown in the development of AI technology [1]. Nasdaq 100 futures dropped by 1.5% and S&P 500 futures fell 0.8% in early trading, with technology companies leading the losses. If these moves persisted throughout the day, it would mark the worst day for the Nasdaq 100 in about six weeks [1].
Nvidia, the world's most valuable public company, saw its shares fall by 3%. Chipmakers Arm Holdings and Marvell, as well as cloud computing provider CoreWeave, each slid 6%. Intel and Hewlett Packard shares tumbled more than 5%, while Corning, a key supplier for data center components, fell 7.5% [1]. Amazon, a leading cloud computing company, dropped almost 2%, Microsoft fell nearly 1%, and Alphabet (Google's parent company) declined about 0.8%. Dow Jones Industrial Average futures fell only slightly, but Dow component Caterpillar, which is involved in AI data center construction, tumbled 3% [1].
The market was further unsettled by OpenAI CEO Sam Altman's statement to Fortune magazine that OpenAI would not go public this year, citing safety concerns: “Given everything happening with safety, right now would be an ill-advised moment to go public” [1]. Both OpenAI and Anthropic's eventual IPOs are expected to be among the largest ever [1].
Deutsche Bank's global head of macro research, Jim Reid, commented, “For markets, the key question is whether this is the first sign that the extraordinary AI investment cycle might eventually moderate.” However, he noted that such moderation seems unlikely given the ongoing competitive race between companies and countries [1].
International markets also reacted strongly. South Korea’s Kopsi index fell more than 3%, driven by heavy selling in AI memory firms. Samsung Electronics dropped 5% and SK Hynix plunged more than 7.3%. In Tokyo, shares of OpenAI investor SoftBank Group fell 10.7% [1].
The market moves followed statements from Anthropic CEO Dario Amodei, who wrote that AI companies “must slow the pace at which we improve the capabilities of AI models,” citing risks such as loss of control of AI systems, misuse for cyberattacks and bioterrorism, and serious economic disruption [1]. OpenAI CEO Sam Altman and Elon Musk both publicly agreed with Amodei’s call for caution [1].
CONCLUSION
The warnings from AI industry leaders about the need to slow development, coupled with delayed IPO plans from OpenAI, triggered sharp declines in technology stocks and related sectors globally. Market participants are now questioning whether this signals a moderation in the AI investment cycle, though competitive pressures may keep momentum high. The immediate market reaction has been strongly negative, reflecting heightened uncertainty around the future pace of AI innovation.
