Alphabet Q3 2026: search revenue grows 12% (below 15% expected), Cloud revenue up 103% to $30.7B, capex $51.4B; stock falls up to 10%

Alphabet reported Q3 2026 results. Search and other revenue was $63.4B, up 12% against roughly 15% expected. Google Cloud revenue rose 103% to $30.7B with $11.1B operating income (36.2% margin). Q3 capex was $51.4B, and 2026 guidance stays at $195-205B with a "significantly higher" figure promised for 2027. Management said AI Mode queries earn less than traditional search. The stock fell by up to 10%. The article gives no links to the filing, so the figures come from the coverage and the extraction, not a checked primary document.

The most useful new fact is management's own admission that AI Mode monetises less per query than classic search. That is a direct test of whether Google can move search users to AI answers without shrinking its profit engine. Cloud growth of 103% suggests enterprise demand for AI capacity is real, but it comes with very heavy spending, so investors, cloud customers and rival search and AI vendors will watch whether returns keep pace. Google's plans to widen chatbot ads and to restrict the full Carbon model initially to select cybersecurity experts and the US government are also worth noting, though the details are thin.

The headline framing that the "AI search problem finally shows up" rests on one quarter of 12% growth, which is slower than hoped but, by the article's own account, roughly in line with recent years. A stock drop of "up to 10%" is an intraday move and says little about lasting damage. The 15% expectation is an analyst consensus, not a company target, and the claim that AI is cannibalising search is not proven by this data.
