Quick Summary

US tech stocks are experiencing sharp declines due to rising concerns about the high costs associated with developing artificial intelligence technology. Intel's stock plummeted by 30% after the company warned of a weaker computer market despite plans to increase AI spending, resulting in a loss of over $130 billion in value. The broader Nasdaq tech index opened at its lowest point in two months, down 2.5%, with other companies like Amazon and Google's parent Alphabet also suffering significant drops in stock prices following disappointing earnings reports and revenue forecasts.

Story summary

On Thursday, October 26, 2026, Google's parent company Alphabet saw its stock price plunge by up to 15.8%, marking one of its worst single-day drops since it began trading over two decades ago and erasing more than $550 billion in market value. This steep decline was triggered by the company missing profit projections and increasing AI spending past $50 billion for the third quarter, causing widespread concerns about whether such massive investments will yield consistent returns. The sharp drop also impacted broader markets, dragging down the tech-heavy Nasdaq index and prompting fears of a potential downturn in artificial intelligence-driven stocks.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
