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.
