Intel’s AI bill hits the tape

That was the sharpest move inside a broader US tech sell-off tied to a question investors keep asking with less patience now: how long the AI build-out can stay this expensive before it shows up cleanly enough in the numbers.

The cleanest shock was Intel’s. In its third-quarter earnings report, finance chief David Zinsner said the company saw “the PC slowdown continuing at least through the first half of next year.” On the earnings call, he also said Intel had significantly ramped up investment in equipment in the third quarter and expected that to be “even more significant” in the following three months.

It is an awkward pairing. One of Intel’s core markets is soft, but the spending still has to rise. Investors can absorb weak demand, or they can absorb heavy investment. Both at once is when a stock starts looking like a referendum on management’s timing.

The rest of the sector did not exactly offer relief. The Nasdaq opened down 2.5%, its lowest level in more than two months, according to the BBC. Amazon fell as far as 6% before recovering after earnings that missed expectations. Reddit was down 26% after weaker-than-expected daily user figures and a warning that Google’s AI-driven search was hurting referral traffic. Roblox fell by nearly 20% as its daily active user numbers dropped.

Alphabet had already helped sour the mood. The Google owner lost more than $500bn in value after saying its AI summaries were affecting core search advertising revenue, and the stock slipped again in early trading. For a market that has spent years treating the largest tech groups as both AI winners and safe earners, that is the part that stings: the spending is visible, the disruption is visible, and the payoff still looks uneven.

Chris Low of FHN Financial told Reuters that big tech companies were showing “some pretty significant growing pains as they aggressively pursue the AI build-out.” Markets were already behaving as if they agreed.
