Microsoft Azure annual revenue crosses $100bn amid heavy AI infrastructure spending
Microsoft’s cloud division has surpassed $100bn in annual revenue, offering investors tentative relief that massive artificial intelligence infrastructure spending is finally translating into broad-based commercial demand.
Microsoft reported an 18 per cent increase in quarterly revenue to $90bn for the period ending 30 June, driven by a 27 per cent surge in its cloud division to $59.3bn. The company’s shares rose approximately 2 per cent in after-hours trading, signalling tentative market relief.
The critical metric for investors, Azure cloud services, grew 43 per cent year on year, exceeding the 40 per cent expectation and accelerating from the previous quarter. For the full financial year, Azure revenue surpassed $100bn for the first time.
This acceleration is particularly notable given Microsoft’s recent constraints in computing power. The company has previously been forced to ration chips among its Azure clients, internal research divisions, and its Copilot services, making sustained growth through this capacity squeeze a strong indicator of underlying demand.
Crucially, the source of this demand appears to be diversifying. Microsoft’s commercial backlog, representing revenue booked but not yet recognised, jumped 84 per cent year on year to $678bn.
The company noted that sequential growth in this backlog was driven by customers outside the major artificial intelligence model developers. This eases previous concerns that the cloud boom was overly reliant on a single partner, following January disclosures that roughly 45 per cent of the backlog was tied to OpenAI.
Enterprise adoption of Microsoft’s software offerings is also scaling. Paid seats for the Microsoft 365 Copilot assistant have now exceeded 30 million, a significant increase from 20 million reported in July.
However, the financial cost of sustaining this growth trajectory remains steep. Microsoft spent $35.8bn on property and equipment in the quarter alone, more than double the $17bn recorded a year earlier, bringing full-year capital expenditure to approximately $116bn.
Global investors have grown increasingly uneasy about these mounting outlays, contributing to a 19 per cent decline in the company’s stock price this year. The modest after-hours gain suggests the market is currently willing to accept the spending, provided revenue continues to match the pace of investment.
The headline net income figure of $35.8bn, a 31 per cent climb, also requires careful interpretation. This growth was partially inflated by a one-off $3.2bn gain related to Microsoft’s stake in the artificial intelligence laboratory Anthropic.
Additionally, reported costs were suppressed by the company’s first voluntary retirement programme, though this was partly offset by an Xbox writedown. When stripping out investment swings related to OpenAI, underlying profit growth stood at 22 per cent.
While artificial intelligence cloud demand is demonstrably real and expanding beyond early adopters, the enormous capital required to build out the necessary infrastructure ensures that financial scrutiny will remain intense.
