The global data center construction market was valued at USD 212.0 billion in 2025. The market is estimated at USD 258.0 billion in 2026 and is projected to reach USD 735.0 billion by 2036, at a CAGR of 11.0% during the forecast period 2026-2036. This report provides a detailed assessment of the market, covering power availability and grid connection, connection policy, construction methods and programs, specialist labor, cost per megawatt, the value chain, the contractor landscape, and future growth opportunities.
The market covers the design, engineering, construction, installation, and commissioning work through which a data center is delivered, along with the building systems installed in it, such as power distribution, standby generation, and cooling. Servers, storage, and network hardware are excluded, as are land and real estate costs, post-handover operations and maintenance, management software, and utility network reinforcement carried out by system operators. Equipment installed in the facility is measured as a product market in separate coverage, so the two totals should not be added, and a total project value that included IT equipment would be considerably larger.
According to Lawrence Berkeley National Laboratory, 2,061 GW of generation and storage was actively seeking U.S. transmission interconnection in 2025, with more than 750 GW of requests withdrawn during the year. Queued gas capacity grew 86 percent to 253 GW as solar, storage, and wind fell. Signing an interconnection agreement took a median of more than three years, and reaching commercial operation took over five, while a data center shell can be built in eighteen to thirty months. Just 13 percent of capacity requested between 2000 and 2020 was operating by late 2025, which shows that announced capacity is a weak guide to actual construction.
Grid connection timescales are the main restraint, since they exceed construction programs, cannot be shortened by spending more, and decide where facilities can be built at all. Shortages of high-voltage electricians, controls specialists, and commissioning engineers also limit how many projects a region can run at once, leading to schedule risk and wage increases. Contractors are challenged to guarantee energization dates that depend on network works outside their control and to size their businesses against pipelines that can be deferred faster than fixed overhead and trained labor can be shed.
Integrated delivery of generation and storage alongside the facility is a major opportunity for contractors with both data center and energy infrastructure skills. Retrofit and density upgrades carried out around live operations command premium rates, prefabricated power rooms and cooling modules help compress schedules, and front-end advisory on where grid capacity actually exists leads into delivery work. Key trends include the extension of the construction boundary to power generation and grid works, lower redundancy specifications for AI training halls, where an interrupted run restarts from a checkpoint, and the growth of prefabrication for schedule reasons rather than cost.
By service, the data center construction market is segmented into design & engineering, civil & structural construction, building envelope & architectural fit-out, electrical systems installation, mechanical & cooling systems installation, fire protection & life safety, security & physical infrastructure, commissioning & testing, and project & construction management. Electrical systems installation holds the largest share in 2026, as power delivery is the core purpose of the building, the scope spans substations, distribution, standby generation, and UPS installation, and its specialist labor makes it the most expensive scope per unit of capacity. Mechanical and cooling systems installation is expected to grow at the highest CAGR, as direct liquid cooling adds pressurized coolant circuits, distribution units, secondary loops, and much larger heat rejection plant, and retrofit halls require this work to be done around live operations.
By construction approach, the data center construction market is segmented into traditional stick-built, prefabricated & modular, hybrid, and retrofit & conversion. Stick-built construction leads in 2026, as it adapts to site-specific conditions that standard modules cannot, relies on established supply chains and trades in every market, and suits bespoke campus designs with too little repetition to justify factory tooling. Prefabricated and modular construction is expected to grow at the highest CAGR, because factory-built power and cooling modules shorten the critical path, move quality control off site, and reduce reliance on scarce local trades. Buyers accept the higher cost per unit of capacity because time, not money, is the binding constraint.
By tier, the data center construction market is segmented into Tier I & II, Tier III, and Tier IV. Tier III holds the largest share in 2026, as it is the standard for colocation and enterprise facilities that contract concurrent maintainability to tenants and the level to which most existing facilities are designed. Tier I and II facilities are expected to grow at the highest CAGR, as AI training halls are increasingly built with lower facility redundancy, given that an interrupted training run can restart from a checkpoint and resilience is moving to the compute and scheduling layer. This lowers electrical and mechanical scope per megawatt.
By data center type, the data center construction market is segmented into hyperscale, colocation, enterprise, edge, and AI & high-performance computing (HPC)-optimized. Hyperscale facilities lead in 2026, reflecting the concentration of committed capacity in large campus phases, standard designs that support industrialized delivery, and the size of each program. AI and HPC-optimized facilities are expected to grow at the highest CAGR, as their rack densities require liquid cooling and reworked electrical distribution, their owners trade redundancy for speed, and large programs are dedicated to training capacity.
By power provision model, the data center construction market is segmented into grid-connected only, on-site generation required, behind-the-meter & co-located generation, and hybrid systems with storage. Grid-connected projects hold the largest share in 2026, as most facilities still rely on utility supply with standby generators for outages, and most jurisdictions do not yet require developers to provide their own capacity. Projects requiring on-site generation are expected to grow at the highest CAGR, as constrained jurisdictions shift the supply obligation to developers, following the example of Ireland's connection policy, which other regulators facing similar constraints can readily adopt.
By project type, the data center construction market is segmented into greenfield new build, campus expansion, retrofit & density upgrade, and shell & core only. New build greenfield projects hold the largest share in 2026, given the volume of committed capacity on new sites, the full civil, structural, envelope, electrical, and mechanical scope each involves, and the preference of large programs for sites designed around current requirements. Retrofit and density upgrades are expected to grow at the highest CAGR, as existing halls were designed for far lower densities, the land, grid connection, and planning consent already exist, and the restrictions of working near live critical load support higher rates.
North America is set to hold the largest share of the data center construction market in 2026, supported by the concentration of committed AI capacity programs, a large contractor and engineering base, and land and grid capacity in certain U.S. states at a scale not available elsewhere. The region also faces the most acute power constraint in absolute terms, as Lawrence Berkeley National Laboratory data show the biggest active queues in the non-ISO West and ERCOT.
Asia-Pacific is expected to grow at the highest CAGR during the forecast period, driven by sovereign capacity programs in several countries, available construction labor, local manufacturing of prefabricated modules, and grid and permitting regimes that deliver connections faster than in Europe or North America in some jurisdictions. In Europe, power policy shapes the market more than demand, as connection rules such as Ireland's enlarge each project but reduce the number that proceed, so value growth comes increasingly from scope per facility. The Middle East & Africa is smaller but expanding quickly, supported by Gulf sovereign programs with available power and land, while Latin America is at an early stage, led by Brazil, Chile, and Mexico.
Contractors in the data center construction market compete on their ability to commit to an energization date rather than on price. General contractors with sector experience compete on program certainty, supply chain control, and the ability to repeat hall designs across a customer's portfolio, while specialist electrical and mechanical subcontractors hold the scarcest skills. Design and engineering firms define scope and now often advise on site viability, and commissioning agents verify performance before handover. Advantage is shifting to firms with energy infrastructure capability, as connection rules bring generation and grid works into the program, and to those with proven references for working safely around live critical load in retrofits.

Market Dynamics
Growth in the data center construction market is driven by AI capacity programs placed in campus phases with power-on dates fixed before design is complete, which rewards contractors that can commit to a date rather than offer the lowest price. Power shortages are also enlarging the scope of each project. In Ireland, the Commission for Regulation of Utilities decided on December 12, 2025, that new data centers must supply generation or storage, on site or nearby, matching their requested maximum import demand, and must source no less than 80 percent of annual demand from new renewable projects in Ireland. Such rules move generation, storage, and grid works from the utility into the construction program. The shift to direct liquid cooling and the retrofit of existing halls for higher rack densities add further mechanical and electrical work.Grid connection timescales are the main restraint, since they exceed construction programs, cannot be shortened by spending more, and decide where facilities can be built at all.
