Nasdaq slides as AI spending doubts mount
US tech stocks fell sharply on Friday, with the Nasdaq 100 down 3% in early trading and on course for its worst one-day drop since mid-June. The broader S&P 500 fell more than 1.2%, and its tech sector tumbled over 3.5%.
The declines followed quarterly earnings from Amazon and Intel that investors found unconvincing. Amazon reported that its AI-related spending continued at a faster clip than expected while growth in its core online shopping business slowed. Intel warned of a weaker computer market even as it plans to increase AI spending.
Intel and Amazon lead losses
Intel shares plunged as much as 30% after the chipmaker forecast lower-than-expected fourth-quarter revenue. Finance chief David Zinsner said the company did not expect to bring in more cash than it spent this year and that the PC slowdown would continue at least through the first half of next year.
Amazon shares fell as much as 6% before recovering to trade about 1.6% lower. CEO Andy Jassy told shareholders to expect approximately $220 billion in 2026 cash capital expenditures, with meaningfully more spending in 2027. Other tech stocks also fell, including Reddit, down 26%, and Roblox, down nearly 20%.
Why did Intel shares plunge on Friday?
