Alphabet’s AI bet has turned its search cash cow into a market panic.
Alphabet says its full-stack AI strategy is expanding search usage, cloud demand and Gemini’s reach; investors and sceptical analysts see a harsher trade-off, with AI potentially weakening the advertising engine that must finance the spending spree.
Alphabet entered its third-quarter results with a powerful AI-growth narrative. Revenue rose 25% to $127.6 billion, while Sundar Pichai said the company had reached a half-trillion-dollar annual revenue run rate. He argued that AI investment was lifting search activity, including commercial queries, with year-over-year query growth at a five-year high.

But Wednesday’s earnings release exposed the fault line beneath that optimism. Google Search revenue still grew 12% to about $63.4 billion, yet missed expectations and slowed sharply from earlier in the year. Google’s Philipp Schindler acknowledged that AI Mode’s rapid growth had an impact because of its “lower monetization” — a candid admission that conversational answers are not yet as lucrative as traditional search ads.2
Alphabet’s defence is that the investment is producing tangible demand. Google Cloud revenue more than doubled to $30.7 billion, its backlog reached roughly $560 billion, and the company says Gemini is being deployed across advertising systems to improve relevance and performance. Schindler said AI now “drives the majority of our product launches,” while advertisers used Gemini to create more than 1.5 billion campaign assets in the quarter.3
Critics, however, see a business funding that promise at an uncomfortable price. Capital expenditure hit about $51 billion in the quarter, free cash flow sank to negative $9.1 billion, and Alphabet kept its 2026 spending target at as much as $205 billion while signalling another major increase in 2027. David Wagner of Aptus Capital Advisors distilled the market’s concern: “In a market worried about AI chatbots cannibalising its key franchise, investors need to see it accelerating, not decelerating.”4
By Thursday, the verdict was brutal: shares fell about 13%, erasing roughly $500 billion in market value. The contrast with Microsoft — which also spent heavily but retained positive free cash flow — intensified worries that Alphabet’s problem is not demand for AI, but whether its old profit machine can pay for the new one.5
The bullish case remains that Cloud matters more than one soft search quarter. Analyst Dan Ives called it “the Cloud print we have been waiting for,” arguing bears would overemphasise the lighter search result.6 Yet the rout showed investors are no longer willing to take that outcome on faith.
