Alphabet loses $500bn in its worst-ever Wall Street day amid fears its OWN AI is eating into Google's search profits

Alphabet's share price plunged more than 12% on Thursday, erasing $500bn in market value in the worst single session across the company's 22-year existence — behind only Nvidia's $593bn collapse in January 2025. The sell-off followed a double miss on earnings and revenue: net profit fell 25% to $26.2bn, and free cash flow turned negative to the tune of $9.1bn, only the second time that has happened.
Google's AI-generated search summaries are now eating into the advertising slots that underpin the whole business, with advertising revenue of $82bn coming in below the $83.4bn analysts had forecast.
Alphabet's cloud division offered the sole bright spot, with revenue more than doubling to $30.7bn — yet investors are pressing for AI-driven gains in search, not just in cloud.
British pension and ISA savers are also feeling the pain, as the Nasdaq dropped nearly 2% and the broader sell-off pulled down funds with exposure to US technology stocks.
