The United States remains the world’s largest and most dynamic data center market by a wide margin, and as of mid-2026 industry trackers describe an industry racing to keep pace with AI demand: CBRE reported that data center supply across primary U.S. markets grew 36% during 2025 to reach 9,432 megawatts, with vacancy falling to a record-low 1.4% even as another roughly 5,994 megawatts sat under construction. One census counted 1,259 existing U.S. data center buildings as of June 2026, with another 162 under construction and 328 proposed, though because power reporting is voluntary these figures are treated as floors rather than firm totals. Northern Virginia’s ‘Data Center Alley’ around Ashburn remains the undisputed center of gravity, with Northern Virginia alone accounting for roughly 4,039.6 megawatts of colocation inventory — about 43% of the entire U.S. primary-market total — while Phoenix has emerged as the clear number-two hub with about 1,380 megawatts commissioned. The country’s oldest interconnection points, the ‘carrier hotels’ at 60 Hudson Street in Manhattan (built 1930 for Western Union) and One Wilshire in Los Angeles (opened 1966, now also known as CoreSite LA1), remain vital physical chokepoints for global network traffic, alongside 350 East Cermak in Chicago and the NAP of the Americas in Miami.

AI Data Centers in USA

The clearest example of AI-optimized infrastructure in the U.S. is OpenAI and Oracle's Stargate campus in Abilene, Texas, built by Crusoe, where the first buildings went live in September 2025 running Nvidia GB200 Blackwell GPUs on a single integrated cluster fabric using Nvidia Spectrum-X networking. At full buildout the eight-building, roughly 1.2-gigawatt campus is expected to house up to 400,000–450,000 Nvidia Blackwell GPUs, with a companion 'Frontier' campus in Shackelford County, Texas being developed by Vantage Data Centers for rack densities exceeding 250 kW and a closed-loop, near-zero-water cooling design. Stargate has since expanded to additional announced U.S. sites in Texas, New Mexico, and Ohio as part of a push toward a combined 7–10 GW of AI capacity, though as of early 2026 some expansion plans were reportedly scaled back amid financing and chip-generation sequencing concerns.

Common Questions

How much data center capacity does the U.S. have, and how fast is it growing?

Estimates vary by methodology, but CBRE reported that primary-market data center supply in the U.S. reached a record 9,432 megawatts at the end of 2025, up 36% from the prior year, following a 34% increase in 2024. Goldman Sachs Research forecasts capacity additions accelerating further, to 13.6 GW in 2026 and 36.3 GW in 2027, compared with 6.4 GW added in 2024 and 8.5 GW in 2025.

Which U.S. region has the most data center capacity?

Northern Virginia remains the dominant market, with roughly 4,039.6 megawatts of colocation inventory as of late 2025 — about 43% of the entire U.S. primary-market total. Phoenix ranks as the clear second-largest hub with about 1,380 megawatts commissioned, while Texas is projected by some forecasters to overtake Virginia in relative market share within a few years as it approaches 40 GW of capacity.

Is there large-scale AI/GPU infrastructure being built in the U.S.?

Yes — the most prominent example is OpenAI and Oracle's Stargate campus in Abilene, Texas, where the first two of eight planned buildings began operating in September 2025 housing Nvidia GB200 Blackwell GPUs. Oracle has said it will ultimately deploy over 450,000 GB200 GPUs across the roughly 1.2-gigawatt campus, though OpenAI decided in early 2026 not to expand the site further so as to avoid mixing Blackwell chips with the forthcoming Vera Rubin architecture, with that freed capacity instead going partly to a Microsoft lease of about 700 MW at the same site.

What are the oldest and most important interconnection hubs ('carrier hotels') in the U.S.?

The most historically significant are 60 Hudson Street in Manhattan, built in 1930 for Western Union, and One Wilshire in Los Angeles, opened in 1966 and now also branded CoreSite LA1 — both remain vital physical chokepoints for global network traffic, alongside 350 East Cermak in Chicago and the NAP of the Americas in Miami.

What is limiting data center growth in the U.S. right now?

Power delivery, not demand, is described as the binding constraint as of mid-2026: under-construction capacity actually fell for the first time since 2020, from 6,350 MW to 5,994 MW, because permitting, zoning, and power-procurement delays slowed new development even as 81.5% of capacity under construction was already pre-leased.
