Technology stocks fell sharply on Friday, October 30, after Amazon and Intel reported quarterly results that sharpened investor scrutiny of the cost and payoff of the AI build-out. The Nasdaq Composite closed down 2.86%, its largest one-day percentage drop since June 5, according to Reuters. The decline does not show that demand for AI has disappeared: both companies reported growth in businesses that supply or support AI infrastructure, although AWS revenue covers a broad cloud business rather than AI alone.

Amazon’s cloud is growing fast, but so is its investment bill

Amazon reported third-quarter net sales of $201.9 billion, up 12% year over year. AWS revenue rose 39.3% to $46 billion, its fastest growth in nearly five years, and Amazon reported operating income of $28.1 billion. Those figures show that demand for cloud infrastructure remains robust, according to Amazon’s earnings release.

The cash-flow picture is more complicated. For the 12 months through September 30, Amazon reported a free-cash-flow outflow of $42.4 billion, compared with an inflow of $14.8 billion a year earlier. The company attributed the change primarily to a $94.8 billion year-over-year increase in net purchases of property and equipment, which it said primarily reflected AI investments. Amazon’s release also maintained an expectation of about $220 billion in cash capital expenditures for 2026. These are trailing-12-month and full-year figures, not one-quarter losses or a measure of whether the investments will ultimately pay off.

That contrast—rapid AWS growth alongside a larger infrastructure bill—helps explain why a strong cloud business did not automatically reassure investors. CNBC reported that Amazon missed analysts’ third-quarter sales and earnings expectations, while maintaining its 2026 capital-spending forecast.

Intel’s near-term warning had a different cause

Intel’s third-quarter revenue increased 21% year over year to $16.5 billion. Its Data Center and AI business-unit revenue rose 78% to $7.3 billion, while Client Computing revenue fell 5%, according to Intel’s official results. The company said Q3 revenue, gross margin and earnings per share exceeded its own guidance.

But Intel forecast fourth-quarter revenue of $15 billion to $16 billion and non-GAAP earnings per share of 25 cents. CNBC reported that analysts had expected $17.1 billion in revenue and 43 cents per share. Intel’s finance chief said the PC slowdown could continue through at least the first half of 2027. CNBC also reported that an earlier interruption at an Israeli manufacturing site weighed on the outlook. Those details matter: Intel’s weaker near-term forecast was not simply evidence that demand for AI chips had vanished.

Intel shares fell about 29% on Friday, their worst day since the 1970s, while the Nasdaq Composite lost 2.86%, CNBC reported. Reuters likewise described disappointing Amazon and Intel results as immediate triggers for the broader decline amid concerns about the scale of AI-related spending and the time required to earn returns.

What investors are questioning about AI spending

Companies are racing to build data centers, buy accelerators and expand power and networking capacity. The central question for investors is whether the revenue and cash generated by AI services will grow quickly enough to justify that investment. Amazon’s AWS figures show accelerating cloud growth, but the company does not report what share of that revenue comes specifically from AI workloads. Its cash-flow disclosure shows the cost of expanding infrastructure is also rising.

The two signals can coexist. A market sell-off is a repricing of expectations, not proof that AI demand has collapsed or that every infrastructure investment will fail. Amazon’s cloud growth and Intel’s data-center and AI results remain strong, while Intel’s PC outlook and Amazon’s cash spending give investors reasons to examine execution and returns more closely.

What to watch next

For Amazon, the next questions are whether AWS growth continues and whether operating cash flow can keep pace with capital spending. For Intel, investors will be watching PC demand, manufacturing recovery and whether the company can convert demand for data-center CPUs into sustained results. Across the sector, future earnings reports will show whether AI infrastructure spending is producing measurable customer revenue and cash returns.

Frequently asked questions

Why did tech stocks fall on October 30, 2026?

Reuters reported that disappointing Amazon and Intel results intensified concerns about AI-related spending and the timing of returns. The Nasdaq Composite closed 2.86% lower that day, its largest one-day percentage drop since June 5.

Did Amazon’s cloud growth slow?

Amazon reported that AWS revenue grew 39.3% year over year to $46 billion in Q3. The company does not report how much of that growth came specifically from AI workloads; AWS includes a broad range of cloud services.

Does the sell-off mean the AI boom is over?

No. One day of market declines cannot establish that. Amazon’s AWS and Intel’s Data Center and AI unit both posted strong year-over-year growth; the uncertainty is how quickly that demand will translate into returns relative to the investment required.
