Alphabet disappoints on earnings: first clear sign that AI is biting into Google's search business

The CNBC article, published on October 29, 2026, analyzes Alphabet's third-quarter results. Wall Street punished them harshly for a broad miss against expectations. The most sensitive point was search, the company's core business.

The key figure is this. Revenue in the "search and other" segment grew 12% year over year, to about $63 billion. It fell short of estimates for the second consecutive quarter. At the same time, Google said query growth on its platform was the strongest in five years. CNBC stresses that this gap between usage and revenue is increasingly hard to ignore as more users turn to AI bots and agents, including those offered by Google itself.

The slowdown has been building. Search revenue growth went from 19% in the first quarter to 17% in the second and 12% in the third. Alphabet executives attributed the slowdown mainly to exchange rates. They added that the currency effect will be even greater in the fourth quarter.

The market reaction was forceful. The stock fell nearly 13% on Thursday, its biggest one-day drop on record. On top of revenue came negative free cash flow of $9 billion in the quarter, three times the estimated shortfall. In the second quarter, free cash flow had already turned negative for the first time in Alphabet's history as a public company, at minus $5.9 billion.

The article includes several analyst voices. Gene Munster of Deepwater Asset Management said on "Fast Money" that the new AI-powered services "are going to be a force." According to him, if "personalized bots" take off, they will become the starting point for commerce for many people, which affects Google's position. UBS analysts wrote that the results will bring search cannibalization fears back "to the forefront." Jordan Klein of Mizuho noted that the figure heightens fears that AI and agents will take share from Search and YouTube and damage Google's AI monetization narrative. Gil Luria of D.A. Davidson said fears about the impact of AI, present from 2023 to 2025, appear to be starting to show up in the business. Even so, he advised against drawing hasty conclusions from a single quarter. He also said it will be necessary to reassess what agentic commerce means for Google.

The company argues that Gemini strengthens its advertising business because it improves understanding of user intent and ad relevance. Philipp Schindler, chief business officer, said they continue to accelerate the rollout of Gemini models across their ads infrastructure. He described the biggest update to product listing ads in a decade. According to him, AI drives most product launches. He added that in the third quarter, Gemini models helped advertisers generate more than 1.5 billion campaign assets, more than seven times as many as a year earlier. However, the article notes that none of this solves the problem of search revenue growth.

Cloud is where the AI bet is paying off. Google Cloud revenue more than doubled in the quarter, to nearly $31 billion. The backlog reached about $560 billion, reflecting enormous contracted demand for AI infrastructure. Management expects to recognize slightly more than half of it over the next 24 months. For comparison, Microsoft reported that Azure revenue rose 48% year over year, to $33.2 billion.

That demand explains why Alphabet keeps spending. It maintained its 2026 capital expenditure forecast in a range of $195 billion to $205 billion. It warned that spending will increase significantly in 2027. Part of it goes to its tensor processing units (TPUs), which compete with Nvidia's GPUs and which Alphabet began selling to external customers in the second quarter. The company launched its seventh-generation TPU, Ironwood, in November 2025. Chief financial officer Anat Ashkenazi explained the cash flow logic. Customer deals appear first in the cloud backlog, but the systems have to be built before they are delivered and revenue is recognized. That is why "you see cash going out" while inventory builds up, and the cash will come in when those TPU systems are delivered and billed.

Overall, the quarter paints a picture of a two-speed company. Cloud and AI infrastructure are growing strongly and underpin heavy spending. Search and advertising, the historic source of profits, are losing revenue traction despite rising usage. It remains to be seen whether the shift toward agents and agentic commerce will durably erode search monetization, and how much weight the currency effect cited by management really carries.
