Azure’s AI-Driven Growth: Unpacking the 39% Surge and the Hidden 40%+ Story

Microsoft’s Azure grew 39% year-over-year in Q2 FY2026 — but CFO Amy Hood revealed something remarkable: it could have been even higher.

The Headline Numbers

The Amy Hood Revelation

“If I had taken the GPUs that came online in Q1 and Q2 and allocated them all to Azure, the KPI would have been over 40%.”

— Amy Hood, CFO

This is a crucial insight into Microsoft’s strategy: Azure growth is being deliberately constrained.

The Capacity Allocation Strategy

Microsoft is making a strategic choice to allocate new GPU capacity to:

• M365 Copilot — 15M paid seats, 10X DAU growth
• GitHub Copilot — 4.7M subscribers (+75% YoY)
• First-party AI products — Higher margin than third-party Azure

Rather than maximizing Azure’s reported growth rate, Microsoft is feeding capacity to its own higher-margin AI products first.

Why This Matters

The Implication

Azure’s 39% growth is understated by design. Microsoft is prioritizing platform control and margin optimization over headline growth metrics. The “real” demand for Azure AI services is even higher than the numbers suggest.

AI Services Within Azure

AI services now contribute 13 percentage points of Azure’s growth — meaning roughly one-third of Azure’s growth is AI-driven. This share is accelerating as enterprise AI adoption increases.
