Microsoft FY26: Azure Tops $100B, Copilot Hits 30M Seats

The headline everyone will run with from Microsoft's FY26 Q4 release is that Azure crossed $100 billion in annual revenue for the first time. The number that actually matters is buried a few lines lower: commercial remaining performance obligation, the contracted-but-not-yet-recognized backlog, jumped 84% year-over-year to $678 billion. That is a forward book of business roughly twice Microsoft's entire FY26 revenue, and it is what tells you enterprise AI spend is being pre-committed, not just consumed quarter to quarter.

The topline is strong on its own terms. Q4 revenue came in at $90.0 billion, up 18%, with net income of $35.8 billion, up 31% on a GAAP basis. Intelligent Cloud grew 32% to $39.3 billion, and Azure and other cloud services grew 43%. Microsoft 365 Copilot passed 30 million paid seats, which Satya Nadella framed in the release as evidence Microsoft is "advancing the frontier on the cost-to-outcome curve, ensuring customers transform tokens into results." Amy Hood pointed to Microsoft Cloud revenue of $59.3 billion, up 27%, as the read-through on customer commitment.

Why this matters for anyone competing with or buying from Microsoft: the RPO figure locks in multi-year AI capacity purchases that AWS, Google Cloud and the enterprise SaaS field now have to displace rather than merely win. Copilot at 30 million paid seats is also the first quarterly disclosure I would call unambiguous monetization proof for a generative AI product bolted onto an existing suite.

The honest caveat is that More Personal Computing revenue fell 4%, with Xbox content and services down 10% and Windows OEM and Devices down 7%, so the AI cycle is not lifting the consumer side. And a $3.2 billion Anthropic investment gain contributed roughly $0.27 to EPS this quarter, which means the 31% GAAP net income growth flatters the underlying operating story. What the release does not give you is the Copilot seat ARPU inside that 30 million figure, or how much of Azure's 43% growth is specifically AI workloads versus lift-and-shift cloud migration, both of which will decide how durable the compounding actually is.

Watch the capex line on the earnings call. A backlog that grew 84% has to be served by physical datacenters, and how Microsoft plans to fund that buildout without denting Intelligent Cloud margins is the one question the shareholder letter cannot answer on its own.
