Microsoft Cloud Revenue Hits $63.9 Billion, and the Forecast Carries the Weight
Microsoft Cloud revenue reached $63.9 billion in the fiscal first quarter of 2027, up 30% from a year earlier, or 31% in constant currency, according to Microsoft's earnings release. Azure, the company's cloud infrastructure and platform business (the rented computing power and software tools that run in Microsoft's data centers), grew 48% over the same period.
Constant-currency growth strips out exchange-rate movements, so it shows the pace of sales as if currencies had not moved. The one-point gap between the reported and constant-currency rates means currency translation trimmed the headline figure slightly. The gap was wider a year earlier. In the third quarter of fiscal 2026, Microsoft Cloud revenue of $54.5 billion grew 29%, or 25% in constant currency, a four-point difference. Taken together, the two periods suggest the currency drag has eased, though most investors will still model against the headline growth rate.
Sequentially, the quarter's revenue was $4.6 billion above the $59.3 billion Microsoft reported for the fourth quarter of fiscal 2026, when segment growth was 27%. Comparing with the previous quarter, rather than the year-earlier one, shows how much the business added in a single quarter. That is a useful gauge of the run rate, meaning the annual pace the business would produce if the latest quarter repeated for a full year.
The forward number matters more to the market than the trailing one. Microsoft said it expects Azure growth of 49% to 50% in the second quarter, according to Reuters. Reuters also reported that analysts had estimated second-quarter Azure growth of 47.6%, based on Visible Alpha data. The guided range sits 1.4 to 2.4 percentage points above that consensus, which is the average of analyst estimates.
The broader context here is that a gap of that size matters a great deal for a business this large. Even a small change in the growth rate moves forecast revenue by a meaningful amount, and I would expect analysts to revise toward the guided range first.
In its fourth-quarter fiscal 2026 report, Microsoft said its commercial remaining performance obligation, meaning contracted revenue not yet recognized, rose 84% to $678 billion.
In my view, a backlog growing far faster than recognized revenue gives visibility into future quarters, and that is why the Azure guidance carries weight: it suggests the growth rate has contracted demand behind it. The caveat is that contracted revenue is not the same as recognized revenue. Timing depends on how quickly capacity comes online and how fast customers draw it down.
Reuters reported that Microsoft shares soared more than 15% in late July, their biggest one-day percentage gain in 18 years, after a forecast that the market judged stellar.
The lesson, as I read it, is that a beat on the trailing quarter is largely known by the time it is reported. A guided growth rate above consensus shifts expectations for several quarters at once, which is why that move could price in so much so quickly.
For readers who work with these numbers daily, the practical question is whether the second-quarter guidance holds, and whether the backlog converts into recognized revenue at the pace the 84% growth rate implies. Both can be checked against future reports. Neither can be settled from a single quarter.
