Google's AI Search Cuts Ad Revenue, Alphabet Loses $510 Billion in Market Value

Google's parent company Alphabet lost approximately $510 billion in market value after reporting a decline in advertising revenue, which analysts link to the company's own AI-generated search summaries reducing user clicks on sponsored links. The stock fell over 12% to a six-month low on Thursday. Alphabet's Chief Business Officer confirmed the AI mode is reducing ad income from traditional search results, though he expressed optimism about its progress. The company's total revenue rose 25% year-over-year to $127.6 billion, but missed analyst expectations, particularly in advertising, triggering investor concern. Former Google advertising head Kim Scott said the company accepts short-term losses to prevent users from switching to rival AI platforms like ChatGPT and Claude. He noted Google's founding philosophy prioritizes long-term investment over immediate returns, viewing AI integration as a strategic necessity despite current financial setbacks.
