United States Data Center Colocation Databook Report 2026: $72.37 Bn Market Led by Equinix and Digital Realty as QTS, Iron Mountain and AI Developers Accelerate Capacity ...

📊 The US data center colocation market is projected to reach approximately $72.37 billion by the end of 2030, growing from $40.21 billion in 2025 at an anticipated 11.5% CAGR.

🚀 Growth momentum will accelerate over the forecast period following a consistent 15.2% CAGR recorded between 2021 and 2025.

⚡ Market expansion is being driven by AI infrastructure build-outs, enterprise hybrid IT adoption, and demand for high-density, AI-ready facilities.

⚖️ The industry faces a structural tension between historically high demand and supply constraints anchored in power access and permitting timelines.

🏆 Equinix and Digital Realty maintain dominant positions in the retail and wholesale colocation segments respectively.

📍 Northern Virginia remains the highest-density global market, with Columbus, Ohio, San Antonio, and Boise emerging as key secondary locations.

❄️ Liquid cooling adoption is accelerating as legacy facilities fail to support the power densities required for GPU-intensive AI workloads.

🏗️ Developers like QTS, Iron Mountain, and CoreSite are expanding into new secondary markets such as Ashburn, Richmond, and Phoenix due to power scarcity in primary hubs.

💼 Enterprises including financial services and healthcare are repatriating some cloud workloads back to colocation environments for cost control and data residency.

🌡️ Providers unable to retrofit or build for high-density power and cooling requirements face increasing tenant churn risks.

⚠️ Dominion Energy's moratorium on new large power connections in Northern Virginia, combined with grid interconnection queues extending to 2030, is forcing development away from saturated markets.

📈 Primary markets will likely see rising lease rates due to constrained new supply, benefiting operators with existing built-out capacity.

🤖 AI-focused colocation developers are scaling rapidly with financing from institutional capital to meet surging demand.

💡 Managed services capabilities layered on top of infrastructure will become key for capturing higher-value contracts as the market matures.

Bullish Signals
  • The U.S. data center colocation market is expected to grow by 16.5% annually to reach $46.84 billion in 2026, accelerating to an anticipated $72.37 billion by the end of 2030.
  • Equinix and Digital Realty maintain dominant positions in retail and wholesale colocation respectively, leveraging their secured power capacity for structural advantage.
  • Iron Mountain has expanded its colocation footprint through continued development in Phoenix and Denver.
  • QTS (Blackstone) is scaling hyperscale-focused campuses in Ashburn, Richmond, and emerging secondary markets.
  • CoreSite operates in major metro markets with strong enterprise and network-dense positioning to capture hybrid IT demand.
  • AI-focused colocation developers such as Applied Digital and Vantage Data Centers are scaling rapidly with financing from institutional capital.
  • Equinix and Digital Realty have announced high-density expansions in Northern Virginia and Silicon Valley corridors to accommodate GPU-intensive workloads from tenants like CoreWeave and Lambda Labs.
  • Enterprise colocation demand is growing as cloud repatriation continues, particularly among financial services and healthcare providers seeking cost and control benefits.
  • Primary markets like Northern Virginia are seeing rising lease rates due to constrained new supply, benefiting existing operators with built-out capacity.
Risk Factors
  • Established operators with secured power capacity hold a structural advantage, implying smaller or less prepared competitors may face significant displacement risks as investment shifts away from saturated primary markets.
  • Power pipeline and grid access are identified as the primary determinants of long-term viability for operators in this market, suggesting that those lacking grid connections face existential threats.
  • In Northern Virginia, available powered shell space has tightened to below 5% as of early 2025, indicating extreme scarcity that could lead to high vacancy risk for new entrants unable to secure land or power immediately.
  • Dominion Energy's moratorium on new large power connections in Northern Virginia, combined with extended utility interconnection queues nationally extending to 2030, creates a severe bottleneck for capacity expansion plans.
  • Facilities capable of supporting high-density compute racks (30kW and above) are currently in short supply across key hubs, leaving legacy operators unable to meet modern AI workload demands without costly retrofits or delays.
  • Providers unable to retrofit or build for high-density power requirements face direct tenant churn risk as demand shifts toward specialized AI-ready infrastructure.
  • The report notes that liquid cooling adoption is accelerating, meaning legacy facilities utilizing air-cooling technologies may become obsolete or non-competitive faster than anticipated.
Full Analysis
The United States data center colocation market is projected to reach approximately $72.37 billion by the end of 2030, driven primarily by artificial intelligence infrastructure and hybrid cloud adoption. According to a report released on April 30, 2026, the market grew at a compound annual growth rate of 15.2% between 2021 and 2025, with revenue reaching $46.84 billion in 2026. Future momentum is expected to sustain expansion, though at a slightly moderated pace of 11.5% annually through 2030. This growth occurs against a backdrop of significant supply constraints, particularly regarding power access and permitting timelines, which favor established operators with secured capacity in primary markets over newer entrants. The competitive landscape is increasingly defined by three key differentiators: AI-readiness, sustainability credentials, and structural advantages in securing power pipelines. Equinix and Digital Realty maintain dominant positions in retail and wholesale colocation respectively, while other major players like QTS, Iron Mountain, CoreSite, Applied Digital, and Vantage Data Centers are scaling rapidly. Iron Mountain has expanded its footprint in Phoenix and Denver, QTS is focusing on hyperscale campuses in Ashburn and Richmond, and AI-focused developers are securing institutional financing to accelerate capacity. Northern Virginia remains the highest-density market globally, though vacancy rates for powered shell space there have tightened to below 5% as of early 2025, while Chicago, Dallas, Silicon Valley, and New York serve as secondary hubs. A critical driver reshaping the industry is the demand for high-density compute capabilities required by large language models, specifically racks capable of handling 30kW or more power density. This has led to a short supply of suitable facilities in Northern Virginia, Silicon Valley, and Chicago, prompting operators like Equinix and Digital Realty to announce expansions to accommodate GPU-intensive workloads from tenants such as CoreWeave and Lambda Labs. The inability to support these high-density requirements with traditional air cooling is accelerating the adoption of liquid cooling technologies. Furthermore, power scarcity in saturated primary markets, exacerbated by Dominion Energy's moratorium on new large connections in Northern Virginia and extended interconnection queues within PJM Interconnection that extend to 2030, is forcing development activity toward secondary markets including Columbus (Ohio), San Antonio, and Boise, where state incentives are reinforcing investment shifts. In addition to AI demand, a stable floor for enterprise colocation is emerging as companies repatriate workloads from public clouds due to cost and control considerations, particularly within financial services and healthcare sectors. Providers like Flexential and Evoque Data Centre Solutions are actively targeting this hybrid IT segment. The industry consensus indicates that differentiation will shift from connectivity and location to power density and cooling capability, with providers unable to retrofit or build for high-density power risks significant tenant churn. As infrastructure constraints redistribute investment away from saturated primary markets, operators with strong managed services capabilities layered on their colocation infrastructure are expected to capture higher-value contracts while benefiting from rising lease rates driven by constrained new supply in established locations.
