Microsoft 365 Copilot hits 30 million paid seats as Azure crosses $100 billion in annual revenue
Microsoft's fiscal Q4 delivered enterprise AI's clearest monetization signal yet — Azure grew 43%, Copilot added roughly 10 million seats in a quarter, and shares jumped 8% after hours.
Microsoft reported fiscal Q4 revenue of $90.01 billion on July 29, up 18% year-over-year, with Azure growing 43% and Microsoft 365 Copilot crossing 30 million paid seats. Shares rose 8% in extended trading. For the first time, Azure’s annualized revenue cleared $100 billion, and for the first time in this cycle, the monetization side of the enterprise AI trade has a number big enough to argue back at the capex side.
The Copilot arc is the tell. CNBC reported the product had more than 20 million paid seats as of April; the fresh figure implies roughly 10 million net adds in a single quarter. Satya Nadella noted GitHub Copilot has reached 50 million users, and that hundreds of enterprise customers have purchased millions of seats of the high-end E7 productivity bundles. “We are advancing the frontier on the cost-to-outcome curve, ensuring every customer can turn tokens into business results,” Nadella said, a sentence engineered to reframe the capex debate around unit economics.
The backlog does the same work more quietly. Bloomberg flagged commercial remaining performance obligations jumping $51 billion in a single quarter, from $627 billion to $678 billion. CNBC noted the sequential RPO growth came from clients other than AI model developers, undercutting the objection that Microsoft’s cloud story is really a circular OpenAI story with extra steps.
Azure’s 43% beat consensus of about 40%. CFO Amy Hood guided to 45% at constant currency for fiscal Q1 2027, above StreetAccount’s 41.4%, and said 2026 capex and investment expectations are unchanged. That’s the goldilocks framing Bloomberg reached for: accelerating revenue against a fixed spending plan. It helps that a data-center useful-life reclassification from 15 to 25 years moved reported 2026 capex from $190 billion to $175 billion.
Contrast with Alphabet, which raised its capex guide to $195–$205 billion and watched shares fall more than 6%, and Meta, which posted $60.8 billion in Q2 revenue while lifting full-year capex to $130–$145 billion. Microsoft also booked a $3.2 billion gain on Anthropic and nearly $5 billion from OpenAI over the year, adjusted EPS of $4.74 against a $4.24 consensus.
The 2000-era hyperscaler debate was whether the buildout would ever be absorbed. Microsoft just showed the absorption curve.
