Microsoft also announced plans to invest around US$ 80 billion in AI-enabled data centers during fiscal 2025, demonstrating the scale of infrastructure investment. These requirements are encouraging enterprises to use colocation facilities that already provide high-density power, advanced cooling, and connectivity rather than undertaking complex upgrades to existing facilities.

Hybrid IT Architectures Sustaining Demand for Colocation Capacity

Hybrid IT is becoming an established infrastructure model rather than a temporary transition between on-premises and cloud environments. Uptime Institute’s 2025 Global Data Center Survey found that 55% of enterprise IT workloads were hosted in off-premises facilities, including colocation, cloud, and other hosted environments, while 45% remained in enterprise-owned facilities. Its 2025 analysis also found that organizations continue to combine cloud, colocation, and owned facilities according to workload requirements rather than pursuing complete cloud migration. This supports colocation demand for workloads requiring predictable performance, data control, interconnection, and proximity to cloud platforms.

Restraints - Rising Construction and Infrastructure Costs Increasing Colocation Capital Requirements

Data center construction costs remain elevated as developers face higher electrical, mechanical, cooling, and specialized infrastructure expenses. Turner & Townsend’s 2025 Data Centre Construction Cost Index, covering 52 markets, found that traditional air-cooled data center construction costs increased by 5.5% in 2025. Its analysis of U.S. projects also identified a 7–10% construction-cost premium for liquid-cooled facilities designed for higher-density AI workloads compared with comparable air-cooled facilities. In addition, 47% of surveyed industry participants reported construction bid-price increases of 6–15% over the preceding year. These cost pressures increase capital requirements and create additional challenges for smaller colocation operators.

Power Availability and Grid-Connection Constraints Limiting Capacity Expansion

Electricity availability has become a significant constraint on new colocation capacity, particularly in major data center clusters. The IEA reported in 2025 that data centers can be built in roughly two to three years, while supporting energy infrastructure requires substantially longer planning and construction periods. The U.S. Department of Energy reported that large transformers for substations and generators have lead times of three to four years, while distribution-transformer lead times reach one to two years or longer. These constraints delay commissioning and increase the value of sites with secured power capacity.

Opportunities - Edge Colocation Expansion for Latency-Sensitive and Distributed Workloads

The expansion of AI inference, industrial IoT, financial applications, and real-time digital services is creating opportunities for geographically distributed edge infrastructure. A 2025 DCD survey identified low-latency processing and real-time data analysis as important drivers of growing interest in AI-at-the-edge deployments. CoreSite is also expanding its metropolitan footprint, with its 180,000-square-foot DE3 facility in Denver, announced in October 2025, designed to support high-density AI, cloud, and other mission-critical workloads. This creates opportunities for colocation providers that combine metropolitan proximity, carrier connectivity, and smaller, high-density facilities.
