Market Size & Share

Market Dynamics

KEY MARKET TREND

Adoption of Liquid Cooling and High-Density Rack Architectures Emerging as a Transformational Trend

• Artificial intelligence training clusters are pushing rack power densities from single-digit kilowatts toward well over 100 kilowatts per rack. This shift is forcing data center operators to replace legacy air-cooled systems with direct-to-chip and immersion liquid cooling technologies capable of removing heat at significantly higher concentrations.
• Equipment vendors are embedding AI-based thermal management software and digital twin modeling into cooling platforms to predict hotspots before they occur. This convergence of controls software with mechanical hardware is transforming cooling from a fixed-capacity utility into a data-driven, continuously optimized system.
• Colocation and hyperscale operators are now specifying liquid-cooling-ready designs in new builds and retrofitting existing halls to support AI workloads. Cooling and power vendors unable to deliver equipment on compressed timelines risk losing multi-year hyperscale supply contracts to faster-moving competitors.
• Vertiv reported that its direct liquid cooling revenue more than doubled year-over-year in the first quarter of 2025, with Dell'Oro Group research noting the technology has become the primary thermal solution for high-density AI deployments.

KEY MARKET DRIVER

Rising Hyperscale and AI-Driven Capital Expenditure on Power Infrastructure Is Driving Market Growth

• Major cloud providers including Amazon, Microsoft, Google and Meta have collectively committed hundreds of billions of dollars to new AI data center campuses through the remainder of the decade. This spending flows directly into demand for electrical switchgear, backup generators, uninterruptible power systems and general construction services.
• The White House-backed Stargate initiative alone has outlined plans for close to seven gigawatts of AI data center capacity and up to USD 400 billion of near-term investment. Projects of this scale require extensive expansion infrastructure spanning power distribution, cooling and site construction.
• Grid operators expect data centers to add well over one hundred gigawatts of new electricity demand in the United States by the early 2030s. This is pushing operators toward on-site generation, battery storage and grid-interconnection upgrades that expand the addressable market for infrastructure vendors.
• ABB announced a USD 110 million investment across four United States manufacturing sites to expand production of Emax 3 circuit breakers and switchgear used to protect power-intensive data centers. The announcement, including site-level detail, is published on ABB's official newsroom.

KEY MARKET OPPORTUNITY

Expansion of Modular and Prefabricated Data Center Construction Creating Significant Market Opportunity

• Prefabricated power rooms and skid-mounted cooling plants allow operators to compress data center deployment timelines from several years down to a matter of months in many cases. This creates a growing opportunity for component manufacturers to sell standardized, factory-built assemblies rather than custom, site-built systems.
• Edge and secondary-market data centers located in smaller cities and regional markets increasingly need compact, modular infrastructure rather than large, multi-year campus construction projects. This opens a distinct growth avenue for vendors that have historically focused their manufacturing capacity on hyperscale-only projects.
• Vendors are increasingly entering long-term manufacturing and supply agreements directly with data center developers rather than relying solely on one-off equipment orders placed project by project. This shift creates recurring, capacity-reserved revenue streams and deeper customer relationships across the expansion infrastructure supply chain.
• Eaton announced in December 2025 a new manufacturing campus in Henrico County, Virginia, to more than double its regional footprint for critical power distribution equipment serving data center customers.
