Chipmaker Stocks Will Weather Any AI Slowdown

One fear over the past few days is that an artificial-intelligence slowdown, whatever that looks like, might harm the stocks of chipmakers. If AI development takes a breather, the insatiable appetite that has propelled component makers to unprecedented heights would dissipate. Will AI companies still need all those data centers?

The answer is yes. And then some.

The 6% drop in the Philadelphia Semiconductor Index — which tracks the shares of top chipmakers like Nvidia Corp. and Intel Corp. — over the past five days, as AI doom fears have captured the news agenda, is an understandable reaction to the uncertainty created by hyperbolic but not entirely unwarranted talk of an AI-created catastrophe.

But missing from any of the pledges from the hyperscalers, or leading AI shops, is any talk of scaling back the infrastructure buildout. On the contrary. In his 4,500-word “Pausing the AI Frontier” essay, Anthropic co-founder Dario Amodei notes that “pacing does not mean halting model training or technical progress.”

It’s early days, and there’s a faint chance Congress could enforce a slowdown of sorts, but so far there’s no indication of any pulling back in the numbers. Bank of America analysts note sky-high memory costs — a key indicator of demand for the AI buildout — are unchanged. The rental cost for Nvidia’s widely deployed B200 system is $5.72 an hour, BofA said, and has risen steadily over the past two months. Now there may be a lag between AI slowdown talk and AI slowdown action. But don’t bet on it: “2027 remains much a fully booked/contracted year across all compute/networking/memory vendors,” BofA analysts wrote. “And we expect 2028 to also remain tight led by accelerating demand.”
