Microsoft brought 88 data centers online in fiscal 2026

Microsoft said it activated 88 new data centers during fiscal year 2026, disclosed alongside its Q4 and full-year earnings report. The figure was cited as part of the company's broader AI infrastructure buildout.

Why it matters: This is one of the most concrete data points yet on how fast hyperscalers are physically expanding compute capacity for AI workloads, coming right after Google raised its 2026 AI capex guidance to as much as $205 billion. The pace suggests physical build-out and power availability, not just capital, remain the real constraints on how quickly labs and cloud customers can scale training and inference.
