Quick Summary

Google's parent company Alphabet lost over $500 billion in value after reporting its quarterly earnings on Thursday, revealing that AI innovations are negatively impacting ad revenue from its core search business. Despite a 25% year-over-year revenue growth to $127.6 billion, profits fell by 25%, and the company showed negative free cash flow of over $9 billion for the first time in two years. This decline is attributed largely to significant investments in AI technology, which now default to AI summaries on Google searches, reducing ad placements.

Story summary

On October 29, Google's parent company Alphabet saw its stock price plummet by up to 15.8%, erasing over $500 billion in market value, marking one of its worst single-day losses ever. The drop was triggered by the company missing profit projections and revealing it had increased AI spending past $50 billion in the third quarter, causing concern among investors about whether such massive investments will yield returns. In contrast, Microsoft shares rose after beating cloud revenue estimates. This dramatic shift affected broader markets, with major US stock indexes falling significantly, reflecting worries over tech companies' huge AI expenditures.

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.
