Market Size, Share and Forecast

This is a large, mature base growing at a steady pace. In absolute terms, the market is projected to add roughly USD 15 billion over the period. North America held about 40% of global share in 2025 and Europe about 22%.

Key Market Trends and Developments

Gigawatt-scale campuses are moving from rarity to planning norm. Hyperscalers and specialized developers are planning campuses engineered for a full gigawatt or more on a single site. That requires a different approach to power procurement, land assembly and construction sequencing than conventional mega data center development. Industry analysis has identified dozens of proposed gigawatt-scale projects since 2021, though financing, grid connectivity, guaranteed demand, low-carbon power access and planning permissions remain significant hurdles that will likely stop a meaningful share from reaching full proposed capacity.

Liquid cooling is entering the facility design. Rack densities increasingly exceed 30-50 kW, which is accelerating adoption of liquid cooling and advanced thermal management beyond conventional air cooling. Liquid cooling is increasingly incorporated into the design of new facilities rather than treated solely as a retrofit.

Capital providers are co-investing directly. Alternative asset managers and joint venture structures are co-investing in individual campus projects alongside the hyperscale operators that will occupy them, reflecting the unprecedented capital these facilities now require.

Recent developments include:

• June 2026: Microsoft announced a new 2 GW data center campus in Pecos, Texas, to support growing AI and cloud workloads.
• June 2026: Amazon announced an additional USD 13 billion investment in India to expand AI and cloud infrastructure, including AWS capacity in Mumbai and Hyderabad.
• June 2026: Digital Realty acquired approximately 1,440 acres in the Kansas City metro to expand its pipeline of large-scale hyperscale data centers.

Market Growth Drivers

Cloud, AI and big data demand. This is the key driver. Sustained enterprise and consumer demand for cloud services favors mega-scale facilities, where hyperscale operators achieve better economies of scale, higher energy efficiency and lower per-unit compute and storage costs than smaller portfolios.

AI and machine learning adoption. Rising adoption directly expands the compute capacity hyperscale operators must deploy, strengthening the case for campuses that house tens or hundreds of thousands of servers.

Data growth. The global datasphere has reached well over 150 zettabytes in recent years, as cited in the IGTPS report, which requires large-scale infrastructure capable of managing and analyzing volumes that smaller facilities cannot economically process.

Enterprise cloud reliance. According to Eurostat, as cited in the report, 52.7% of EU enterprises used paid cloud computing services in 2025, up 7.4 percentage points from 2023, reflecting rising reliance on cloud infrastructure.

Market Restraints and Challenges

Power availability. The IGTPS report notes that power, rather than capital or land, has become the primary constraint on new mega data center capacity in many established hub markets. Facilities at this scale need enormous electricity and often water resources, which strains regional grids and utility networks.

Project execution risk. Financing, grid connectivity, guaranteed demand, low-carbon power access and planning permissions can prevent announced projects from reaching full capacity.

Capital intensity. Even with large capital providers committing tens of billions of dollars to individual campuses, the scale of investment raises the bar for participation and favors operators with strong financial capacity.

Thermal management. Rising rack densities challenge air-based cooling, which still holds the largest installed base. Moving to liquid cooling requires design changes and new operating practices.

Market Opportunities and Future Outlook

Renewable and nuclear co-location. Operators increasingly want to co-locate campuses with dedicated renewable and nuclear generation. Developers and utilities that can structure these complex power arrangements ahead of competitors relying solely on grid interconnection may gain an advantage.

Emerging hub markets. Operators are looking beyond first-tier corridors for locations with enough land, power and interconnection capacity, which opens opportunities in new regions.

Government and enterprise demand. Customers that need secure, large-scale and increasingly domestically sited data processing capacity represent a distinct segment beyond the hyperscale cloud providers that historically dominated demand.

Upward capacity revisions. Independent real estate and advisory firms tracking global capacity have consistently revised multi-year growth projections upward, as noted in the report, indicating that the pace of hyperscale and AI-driven demand has repeatedly outrun earlier forecasts.

Market Segmentation Analysis

By solution. Storage led, driven by the need to manage expanding data volumes from cloud, enterprise applications, AI model training and digital services. Power and cooling solutions are projected to grow fastest as rising rack density drives upgrades to power distribution, thermal management and liquid cooling. Servers and networking equipment complete the segmentation.
