Google Cloud’s 82% Growth Narrows the Gap, but Not on a Clean Basis

Google Cloud’s second-quarter revenue rose 82% from a year earlier to $24.8 billion, a striking acceleration that strengthens Alphabet’s position in enterprise artificial intelligence. It does not, however, prove that Google Cloud will overtake Microsoft Azure within a year.

Alphabet said the growth came from AI infrastructure, AI solutions and core Google Cloud Platform services. The quarter also included the first revenue from TPU systems sold into customer data centers. Management said growth still accelerated materially when those system sales were excluded, but it did not quantify the adjustment.

Profitability improved alongside revenue. Google Cloud operating income more than tripled to $8.8 billion, lifting segment operating margin to 35.6% from 20.7% a year earlier. That combination matters because rapid infrastructure growth can destroy value if depreciation and capacity costs rise faster than revenue.

Demand is also visible in contracts. Google Cloud backlog reached about $514 billion, more than $50 billion higher than in the previous quarter. Alphabet expects to recognize just over half of that amount as revenue within 24 months. Management nevertheless said capacity remains constrained, which means the pace of data-center deployment can limit near-term sales.

The original analysis compared Google Cloud’s $24.8 billion of quarterly revenue with an estimated $29.4 billion for Azure and then projected each company’s latest growth rate forward for a year. That conclusion is too strong. Microsoft does not report Azure as a standalone revenue line, and Microsoft Cloud includes a broader collection of products than Azure. A one-quarter growth rate also cannot be assumed to persist, especially when Google Cloud’s comparison includes new TPU system sales.

The competitive direction is still important. Google Cloud grew much faster than Microsoft’s disclosed Azure growth rate and Amazon Web Services’ reported pace in the comparable period. But investors should compare like-for-like measures, margins and backlog rather than treat a simple revenue crossover as established fact.

Alphabet is paying heavily for that expansion. The source analysis cited second-quarter capital spending of $44.9 billion and negative free cash flow of $5.9 billion, while management raised its 2026 capital-spending outlook to $195 billion to $205 billion. Those figures make utilization and margin durability central to the investment case.

Alphabet and Microsoft are scheduled to report on October 28. For Alphabet, the decisive numbers are Google Cloud growth excluding unusual hardware contributions, operating margin and the pace at which backlog converts to revenue. If margin remains near the second quarter’s 35.6% while growth stays elevated, the cloud-share thesis strengthens. If margin contracts as outside capacity and depreciation increase, the revenue surge will be less valuable than the headline suggests.
