Government initiatives such as the United States Department of Energy's 2026 classification of data centers as strategic infrastructure, which fast-tracks permitting, federal land access, and grid interconnection for qualifying AI facilities, are accelerating domestic rack infrastructure investment. In parallel, Indian state governments have introduced dedicated data center policies in 2026, including Gujarat's Data Centre Policy 2026-29 targeting 7.5 gigawatts of new capacity and Uttar Pradesh's Data Centre Policy 2026 targeting 2 gigawatts, both offering capital subsidies and power tariff relief specifically for AI-ready, GPU-based infrastructure. By region, North America held the largest share of the market in 2025, supported by the concentration of hyperscale cloud providers and domestic GPU and rack manufacturers across the United States. Asia-Pacific is expected to be the fastest-growing region during the forecast period, driven by expanding sovereign AI compute programs in China, India, Japan, and South Korea, alongside newly launched state-level data center incentive policies across India.

Market Size & Share

Market Dynamics

KEY MARKET TREND

Rack-Scale Reference Architectures and Open Compute Standards Redefining AI Infrastructure Design

• Server and rack vendors are converging around Open Compute Project ORv3 and Open Rack Wide specifications to standardize power shelves, busbars, and chassis dimensions across GPU platforms. This shift allows data center operators to mix components from multiple suppliers within a single rack, reducing vendor lock-in while shortening deployment timelines for large-scale AI clusters.
• Direct liquid cooling has moved from a specialized supercomputing technique into a mainstream requirement, with coolant distribution units now engineered to manage more than 200 kilowatts of heat per rack. Vendors are pairing cold plates, manifolds, and leak-detection sensors into factory-integrated assemblies that arrive pre-tested and ready for rapid on-site commissioning.
• Major infrastructure suppliers are bundling power, cooling, and rack hardware into single pre-validated packages rather than selling components separately, which reduces multi-vendor integration risk for enterprise and colocation buyers alike. This bundling trend is reshaping competitive dynamics in favor of companies that offer complete power-to-chip portfolios rather than specialized single-product manufacturers.
• Legrand expanded its Open Compute Project-aligned rack portfolio in April 2026 with a 33-kilowatt ORv3 power shelf, a 48-volt direct current busbar, and a Rear Door Heat Exchanger rated for high-density AI racks. The announcement, reported by DataCentreNews UK, illustrates how established rack and power manufacturers are retooling their catalogs specifically for GPU-dense computing environments.

KEY MARKET DRIVER

Escalating GPU Power Densities and Hyperscale AI Factory Buildouts Driving Rack Infrastructure Demand

• Modern AI accelerators such as NVIDIA's Blackwell and Rubin platforms and AMD's Instinct MI400 series now draw well beyond 1,000 watts per chip, pushing rack-level power draw from the traditional 10 kilowatts toward 130 to 250 kilowatts in a single cabinet. This surge is forcing operators to replace legacy air-cooled cabinets with purpose-built, high-density rack systems.
• Hyperscale cloud providers are committing tens of billions of dollars annually to new AI-optimized data center campuses, each requiring thousands of GPU racks engineered for extreme thermal and power loads. This sustained capital spending cycle remains the single largest demand driver for rack enclosures, busbars, and coolant distribution hardware worldwide.
• Governments are treating AI data center capacity as strategic economic infrastructure and are fast-tracking permits, land access, and grid connections for qualifying projects. In the United States, federal agencies including the Department of Energy have begun classifying data centers as strategic infrastructure to accelerate development timelines for AI-ready facilities.
• Munters Group announced in May 2026 that it had secured an order worth approximately SEK 2.0 billion, around USD 200 million, from a United States colocation provider for coolant distribution units and over-the-rack cooling systems supporting a modular AI factory build-out. The order was disclosed under EU Market Abuse Regulation rules.

KEY MARKET OPPORTUNITY

Expansion of Colocation Capacity and Sovereign AI Programs Creating New Rack Deployment Opportunities

• Colocation providers are increasingly hosting AI training and inference workloads that were previously confined to hyperscaler-owned facilities, creating fresh demand for retrofit-ready, high-density rack systems that can be installed inside existing data halls without a full facility rebuild. This is opening a distinct market for modular, rack-and-roll cooling and power kits.
• National and state governments are launching dedicated data center policies that combine capital subsidies, power tariff relief, and land incentives specifically to attract AI-ready facilities, creating new regional demand pockets outside the traditional hyperscaler hubs. India's Gujarat and Uttar Pradesh states, for example, unveiled dedicated data center policies in 2026 targeting multiple gigawatts of new AI-ready capacity.
• A large installed base of conventional air-cooled data centers built before the AI boom now needs partial or complete rack-level retrofits to support GPU workloads, creating a multi-year replacement and upgrade opportunity for rack, power, and cooling vendors. Rear-door heat exchangers and hybrid cooling kits are emerging as preferred, low-disruption retrofit products.
• Eaton completed its 2026 acquisition of Boyd Thermal, adding cold plate and precision liquid-cooling manufacturing capacity to its existing rack power and enclosure portfolio, a deal referenced in independent vendor benchmarking coverage of the data center cooling market. The acquisition signals consolidation among suppliers seeking to offer complete power-to-chip rack solutions for AI operators.

Segmentation Analysis

Analysis by Component

Rack enclosures and structural frames held the largest share of the AI Rack Infrastructure Market in 2025, forming the foundational hardware that every power, cooling, and networking component is mounted into. Their dominance stems from the fact that every AI deployment, regardless of GPU vendor or cooling method, requires a physical enclosure before any other rack-level equipment can be installed. Enclosure manufacturers have adapted established 19-inch and 21-inch cabinet designs to Open Compute Project ORv3 dimensions, widened depths, and reinforced load ratings exceeding 1,500 kilograms to accommodate heavier GPU chassis. Established players such as Rittal, Chatsworth Products, and Legrand continue to expand ORv3-compliant frame portfolios, reinforcing this segment's leadership position across hyperscale and colocation deployments.

Cooling systems are projected to grow at the fastest CAGR within the component segment during the forecast period, as GPU thermal design power has outpaced what air-based systems can safely dissipate. Coolant distribution units, cold plates, manifolds, and rear-door heat exchangers are being redesigned to manage individual rack loads exceeding 200 kilowatts, compared with 10 to 15 kilowatts for conventional enterprise racks just a few years ago. Vendors including Vertiv, Delta Electronics, nVent, and Munters have introduced next-generation coolant distribution units rated between 140 and 250 kilowatts specifically to support NVIDIA and AMD's newest rack-scale accelerator platforms, a clear signal that thermal hardware is now the primary engineering bottleneck rather than compute density itself.

Component categories include

• Rack Enclosures & Frames (Dominating Segment)
• Cooling Systems (Highest CAGR Segment)
• Power Distribution Units
• Cable Management & Connectivity
• Monitoring & Management Software

Analysis by Cooling Technology

Air cooling remains the largest cooling technology category in 2025, continuing to serve the broad installed base of enterprise and moderate-density AI inference racks that operate below 40 kilowatts per cabinet. Its dominance reflects lower upfront capital cost, simpler maintenance, and compatibility with existing building infrastructure that does not require dedicated facility water loops. Many organizations deploying AI inference workloads at smaller scale, rather than large training clusters, continue to rely on enhanced air cooling with high-static-pressure fans and rear-door assist units. However, its relative share is expected to erode steadily as GPU power draw per rack continues climbing beyond levels that air alone can safely remove.

Direct-to-chip liquid cooling is projected to grow at the fastest CAGR among cooling technologies as GPU training clusters increasingly require the removal of heat directly at the processor and memory package rather than at the rack or room level. NVIDIA's GB200 and GB300 NVL72 platforms and AMD's Instinct MI400-based Helios racks are natively engineered for direct-to-chip loops, effectively making liquid cooling a default requirement rather than an optional upgrade for frontier AI training deployments. Suppliers such as Schneider Electric, through its Motivair liquid-cooling technology, have scaled manufacturing capacity to meet this shift, reinforcing the segment's rapid growth trajectory.

Cooling Technology categories include

• Air Cooling (Dominating Segment)
• Direct-to-Chip Liquid Cooling (Highest CAGR Segment)
• Immersion Cooling
• Rear-Door Heat Exchangers

Analysis by Rack Power Density

Racks rated between 30 and 100 kilowatts held the largest share of the market in 2025, representing the current mainstream deployment band for enterprise AI inference and mid-scale training clusters built around NVIDIA H100 and H200 class GPUs. This density range strikes a practical balance, allowing operators to use hybrid air-and-liquid or fully liquid-cooled configurations without redesigning entire facility power and water distribution systems. Colocation providers in particular favor this band because it fits within the electrical and cooling capacity of many existing data halls, avoiding the capital cost of a full facility rebuild while still supporting demanding AI workloads.

Racks rated above 200 kilowatts are projected to grow at the fastest CAGR as frontier AI training clusters built on NVIDIA's Vera Rubin NVL72 and AMD's Helios rack-scale platforms push individual cabinet power draw toward and beyond 250 kilowatts. Reference designs jointly developed by Schneider Electric and AMD, and by Eaton and NVIDIA, already specify rack densities in this range paired with 800-volt high-voltage direct current power architectures to manage the associated electrical losses. This segment's rapid growth reflects the leading edge of AI factory construction rather than the current installed base, positioning it as the benchmark that rack, power, and cooling suppliers are now designing toward.

Rack Power Density categories include

• 30 to 100 kW (Dominating Segment)
• Above 200 kW (Highest CAGR Segment)
• Below 30 kW
• 100 to 200 kW

Analysis by End User

Cloud service providers and hyperscalers held for the largest end-user share of the AI Rack Infrastructure Market in 2025, reflecting their position as the primary buyers of GPU-dense rack systems for large language model training and inference at scale. These operators commit to multi-year, multi-gigawatt capacity plans and negotiate direct reference-design partnerships with rack, power, and cooling suppliers, as seen in the Schneider Electric-NVIDIA and Dell-NVIDIA collaborations. Their purchasing scale gives them significant influence over emerging rack standards, including Open Compute Project ORv3 specifications that are increasingly adopted across the broader market.

Colocation providers are projected to grow at the fastest CAGR in end-user category as enterprises and mid-sized AI companies that lack the capital or expertise to build proprietary data centers increasingly lease AI-ready rack space instead. This shift is prompting colocation operators to retrofit existing halls with high-density power distribution and liquid-cooling infrastructure to compete for AI tenants who previously would have gone directly to hyperscalers. The trend is particularly visible in secondary markets and emerging data center hubs where sovereign and state-level policies, such as those introduced in India's Gujarat and Uttar Pradesh, are actively courting colocation investment for AI-ready capacity.
