U.S. Data Center Construction Spending Hit a Record in 2025 as AI Infrastructure Demand Surged
The U.S. Census Bureau, ConstructConnect, CNBC, and JLL all confirm 2025 as a record year for data center construction, though the underlying dollar figures diverge sharply by methodology. Census value-put-in-place data puts data center construction spending at $41 billion, up 32% year-over-year and 344% since 2020, while ConstructConnect's project-starts tracking shows $53.7 billion through November with full-year 2025 projected above $60 billion. CNBC separately reported data center deals and investment hit $61 billion in 2025, and JLL's year-end report shows a 35 GW North America construction pipeline with vacancy locked at a record-low 1% for a second straight year. All four agree AI infrastructure demand is the driver, but the roughly $20 billion spread between government and industry figures reflects different measurement methods rather than disagreement about the trend.

Findings
- U.S. Census Bureau value-put-in-place data shows data center construction spending reached $41 billion in 2025, up 32% year-over-year and 344% since 2020.
- ConstructConnect's project-starts tracking recorded $53.7 billion in U.S. data center construction spending through November 2025 (+138.6% YoY), with full-year 2025 projected to exceed $60 billion.
- CNBC reported data center deals and investment hit a record $61 billion in 2025 amid a global "construction frenzy."
- JLL's year-end 2025 North America Data Center Report tracked a 35 GW construction pipeline with vacancy locked at a record-low 1% for a second consecutive year.
Data center developers, hyperscale tenants, construction contractors, and infrastructure investors planning 2026-2027 capital allocation need to know whether 'record data center construction spending' headlines are converging on one number or measuring different things; UVRN's delta engine flags the spread between government value-in-place data and industry project-tracking data so decision-makers do not anchor on a single figure without understanding its methodology.
