Shares of Alphabet, Google’s parent company, plunged following its latest quarterly results: the company’s market capitalization fell from $3,970 billion on Wednesday to $3,460 billion on Thursday — a loss of nearly $500 billion — according to the BBC. The stock dropped 13% after the report was released.
What the report showed
The quarter’s figures were mixed. Total revenue rose 25% year over year to $127.6 billion. At the same time, profit fell by 25% during the quarter, and Alphabet reported negative free cash flow for only the second time since its stock listing: the shortfall amounted to $9 billion.
Free cash flow measures how much cash remains after operating costs and capital investments; the company’s report indicates that Alphabet spent more cash than it generated in the quarter.
AI investments are weighing on ad revenue
Most of the increased spending flowed into Google’s artificial intelligence efforts, notably the Gemini project. Those investments are also reducing ad inventory in the short term: because Google’s AI produces summaries for search results, there was less space to display ads during the quarter. Advertising sales remain Google’s primary revenue source, so this substitution squeezed advertising income.
Similar market moves at other tech giants
Amazon’s shares also fell sharply: they lost 11% on Thursday after the company reported free cash flow of minus $42 billion for the quarter, while revenues grew by 11%. CEO Andy Jassy defended the heavy spending by saying the company has two business opportunities that could each generate $1,000 billion in revenue in the future; he did not specify them, though the report notes this could plausibly refer to Amazon’s custom chips and the Bedrock AI development platform.
Among the three large tech companies mentioned, only Microsoft avoided a comparable sell-off. Some analysts attributed this to Microsoft’s quarter being viewed as stronger than expected and showing signs of sustainable growth.
Broader significance
As Bloomberg notes, the post-earnings sell-off highlights rising tensions around the AI transition and how to finance it. Major tech companies have issued unprecedented amounts of debt, taken loans and assumed multibillion- or even trillion-dollar commitments to fund AI development. In some firms, AI investments are beginning to erode profits from established business lines, raising concerns among investors.
Conclusion
Quarterly reports show that large-scale AI investments can dent short-term profitability and free cash flow, triggering sell-offs by investors. Alphabet’s case is notable: despite robust revenue growth, negative free cash flow and reduced ad monetization prompted a significant market reaction.
