Microsoft grows Azure while new capacity slips

Microsoft’s Azure revenue reached $33.2 billion in the quarter ended 30 September, up 48% from a year earlier. Results released on 28 October put total company revenue at $92.3 billion, up 19%.[1]

CFO Amy Hood said engineering improvements freed capacity across existing GPU and CPU fleets, helping Azure grow even as third-party infrastructure deliveries slipped. Higher revenue per token also helped. Demand still exceeded supply.[2]

The spending calendar

Microsoft now expects roughly $170 billion of capital expenditure in calendar 2026. Hood expects spending to accelerate in the second half of fiscal 2027, including delayed capacity deliveries. The spending moves between periods; the capacity requirement remains.[2]

Cash and capacity

The accounts show $58 billion of operating cash flow and $39.367 billion of cash additions to property and equipment. Subtracting the latter gives $18.633 billion, before acquisitions and other investing flows. That calculation describes cash available after physical investment, rather than the company’s overall change in cash.[1]

Hood’s broader quarterly capital-expenditure figure was $45.2 billion. Microsoft counts the full principal of a finance lease when it begins, so that measure differs from cash paid for equipment.[2]

Azure’s reported revenue covers the cloud business; the release does not identify it all as AI revenue. The infrastructure story is therefore larger than model usage alone. Existing capacity, new construction and cash payments are separate things to watch.[1]
