On Monday, tech stocks dropped heavily following calls from top AI company leaders to slow down development. The decline affected the Nasdaq Composite, the S&P 500, and the Dow Jones Industrial Average, with chipmakers Nvidia and Micron Technology among those suffering the largest losses.
Investors are weighing whether the spending surge fueling the market can keep going, and that uncertainty has weighed on stocks tied to it. Nvidia’s shares declined 3.4%, while Micron Technology’s dropped 5.2% on the day.
Early Trading Numbers
Early trading saw the Nasdaq Composite Index fall by about 1%. The wider S&P 500 declined 0.6%, while the Dow Jones Industrial Average, made up of blue-chip stocks, lost ground by 0.6%.
The strain showed up most clearly in the semiconductor industry. Both Nvidia and Micron Technology manufacture high-end components for artificial intelligence systems, and both suffered notable declines in value during the session.
Vital Knowledge’s head of investment advisory, Adam Crisafulli, said “pick and shovel” stocks — companies that provide AI infrastructure and resources — are taking the biggest hits.
“Markets are trying to figure out what the pace [of AI development] is, and there will be winners and losers depending on what that pace is,” David Royal, chief financial and investment officer at financial services provider Thrivent, told CBS News.
“I’m not too alarmed by what we’re seeing today, but you are seeing some individual names in the chip space that are getting hit pretty hard,” he added.
The Leaders Who Spoke Up
Major AI company leaders have issued public statements urging the industry to move forward with greater caution in order to protect against possible hazards. These warnings grew stronger following the weekend publication of an essay by Anthropic CEO Dario Amodei, who called for the industry to “pace the frontier.” His essay argued that the industry had long understated the risks of its work.
“For too long the industry lied” about AI risks, Amodei told CBS News senior business and technology correspondent Jo Ling Kent in an interview. Elon Musk, CEO of SpaceX, which owns xAI, and Sam Altman, CEO of OpenAI, echoed Amodei’s calls for a slowdown.
Three industry leaders from separate corners of the field issued a shared appeal for restraint. One executive runs Anthropic, which develops AI systems. Another runs SpaceX, which owns xAI, while the third runs OpenAI. Each of these three operates a prominent AI business, and their joint call for caution came from people running such companies.
The Concentration Problem
The stock market has climbed to record heights driven largely by investments in AI. But now, with billions of dollars in AI spending expected to outstrip corporate profits, investors fear that pressure could trigger a downturn.
Stock market performance has become increasingly concentrated in a handful of tech companies. Any major tech sell-off threatens to hurt investors and drag down Americans’ 401(k) plans.
Bank of America Global Research says five companies will make up 27% of the gains expected from the S&P 500 over the next 12 months. The five are Alphabet, Apple, Micron Technology, Microsoft and Nvidia. Of that total growth, tech stocks will contribute 50%, the firm estimates.
When just a handful of companies carry most of the weight, a single weak day can ripple through the whole list. The danger is that if those five stocks fall short, the whole gauge gets pulled down with them.
Near-Term Rally, Long-Term Risks
Capital Economics is forecasting a near-term continuation of the AI-fueled market rally while warning that longer-term risks are building. The investment adviser projects the S&P 500 will reach 8,250 by year-end. At the same time, it expects the AI bubble currently being fueled by investor enthusiasm to pop next year, causing a more than 20% decline in the S&P 500 by the close of 2027.
Crisafulli expressed worry over the rate of AI spending. Still, he noted that even if AI CapEx slows sharply, it would not automatically cause a full market downturn.
He said “I think it’s more nuanced than just bubble, no bubble,”. “This pace of spending is absolutely not sustainable. But that doesn’t mean everything that is associated with AI has to suffer as a result.”
What the analyst is saying concerns the speed of spending rather than the form of the market.
The Sell-Off’s Scale
The executives’ statements triggered an instant market reaction, with declines led by chipmakers. Nvidia fell 3.4%, while Micron Technology declined 5.2% on the day.
Here is what happened on Monday:
- Three major AI leaders — Amodei, Musk and Altman — called for a slowdown
- Chipmakers Nvidia and Micron Technology led the declines
- Bank of America Global Research says five stocks drive 27% of S&P 500 growth
- Capital Economics sees a 20%+ drop by the end of 2027
These are observations from Monday’s trading, not warning signals.
On Monday, the market reacted fast to signals coming from the industry’s top executives. Whether the AI bubble will burst next year stays an open question. What matters for now is how the market responds to what the leaders themselves have said.
