● Azure (Microsoft): +44% constant currency — beat 39-40% guidance. Full-year CapEx $175B (flat).
● Google Cloud (Alphabet): +82% YoY — $12.3B revenue in Q2. CapEx: $44.9B in Q2 alone.
● AWS: Q2 results not yet reported as of July 31.
● Market reaction: Azure +44% = MSFT +15.5%. Cloud +82% = Alphabet fell. Reason: CapEx efficiency signal.
● AI revenue contribution: Azure AI and OpenAI Service named as key Azure growth driver. Google Cloud AI named as key driver.
Google Cloud's 82% growth is the stronger absolute number. Microsoft Azure's 44% growth is the stronger market signal — because it came with flat CapEx guidance. Investors right now are not rewarding the highest growth rate. They are rewarding the most efficient growth rate. Alphabet's Q2 CapEx of $44.9 billion in a single quarter implies a full-year rate of approximately $180 billion — higher than Microsoft's full-year $175 billion guidance — while Azure is growing faster on a percentage basis. The market's interpretation: Microsoft's AI infrastructure investments are translating into cloud acceleration more efficiently than Alphabet's.
For AI developers choosing a cloud: Google Cloud has the highest raw growth and the deepest Gemini/Vertex AI integration. Azure has the broadest OpenAI integration (Azure OpenAI Service, Copilot). Both are accelerating. The CapEx signal matters for pricing stability: a cloud provider under investor pressure to reduce CapEx may slow infrastructure expansion, which affects capacity availability in specific regions.
