Northern Virginia — and Ashburn specifically — is the world’s densest concentration of data center capacity, and Microsoft Azure anchors a large share of it. Across Loudoun and Prince William counties, Microsoft operates multiple hyperscale campuses that collectively host a significant fraction of Azure’s global compute, including the infrastructure that serves the OpenAI API, Azure OpenAI Service, and Bing AI features. Microsoft committed $80 billion in global data center capital expenditure for FY2026, with the United States receiving over half. The Northern Virginia footprint is continuously expanding as AI inference demand for GPT-4, GPT-4o, and successor models accelerates. Each campus connects to the PJM grid and is backed by large renewable energy purchase agreements from solar and wind projects across the mid-Atlantic.
