Market Size & Share

Market Dynamics

KEY MARKET TREND

Rack-Scale Liquid Cooling Standardization Emerging as a Transformational Trend

• AI accelerator power draw has pushed typical rack densities well beyond the 20 to 40 kW ceiling that air cooling can economically support. Deloitte projects that next-generation AI racks could reach densities of up to 370 kW during 2026, effectively removing air-only cooling as a viable option for GPU-dense deployments.
• Rack vendors are now co-engineering direct-to-chip cold plates, rear-door heat exchangers and coolant distribution units as native rack components rather than retrofitted additions. This approach allows thermal architecture to scale in step with successive GPU generations, including NVIDIA's Blackwell and upcoming Rubin platforms, without redesigning the surrounding rack structure.
• Hyperscale operators are adopting liquid cooling at scale, with industry reporting indicating that more than 80% of Google's AI servers already use liquid cooling and that AI chip liquid cooling penetration is projected to reach roughly 53% industry-wide in 2026. This reflects a shift from pilot deployments to default rack architecture.
• The Open Compute Project's ORv3 rack and power specification has become a shared reference architecture for AI racks, with member companies including Meta, Microsoft and Google collaborating on open busbar, power shelf and rack designs.

KEY MARKET DRIVER

Surging Deployment of GPU-Based AI Training and Inference Clusters is the Key Driver

• Hyperscale cloud providers and AI-native companies are commissioning large GPU clusters to train and serve increasingly large language and multimodal models, directly increasing demand for racks engineered to house dozens of GPUs per enclosure. This has made rack-scale integration, rather than individual server procurement, the standard unit of AI infrastructure planning.
• Rack power densities have climbed from roughly 15 to 20 kW in conventional enterprise deployments to well above 100 kW for current-generation NVIDIA GB200 and GB300 NVL72 racks. This step-change in density is compelling operators to replace legacy rack fleets with structurally reinforced, high-current enclosures built for sustained GPU workloads.
• Rising global data center capital expenditure, projected by Eaton to surpass USD 1 trillion by 2029, is translating directly into higher order volumes for AI-ready racks, power shelves and cooling infrastructure. Rack and power vendors are expanding manufacturing capacity across multiple regions in response to this sustained demand growth.
• Eaton announced a new manufacturing campus in Henrico County, Virginia, representing an investment exceeding USD 50 million and creating 200 jobs, dedicated to producing static transfer switches, power distribution units and remote power panels for AI data center deployments. Details are available at eaton.com.

KEY MARKET OPPORTUNITY

Expansion of Open Rack Standards and Retrofit Cooling Creates Significant Market Opportunity

• Data center operators managing existing air-cooled facilities represent a substantial retrofit opportunity, as rear-door heat exchangers and rack-level coolant distribution units allow high-density AI racks to be deployed inside legacy white space without full facility redesign. This lowers the barrier for enterprises seeking to add AI capacity within existing data center footprints.
• Growing adoption of Open Compute Project ORv3 and NVIDIA MGX rack architectures is opening the market to a broader base of rack, power shelf and busbar suppliers beyond traditional OEM channels. This is creating new revenue opportunities for component manufacturers able to certify products against open, vendor-neutral rack specifications.
• Colocation providers are increasingly offering dedicated high-density AI suites with pre-qualified liquid-cooled racks, creating a distinct commercial segment separate from traditional enterprise colocation. This is expanding demand for standardized, pre-validated rack-and-cooling packages that colocation operators can deploy repeatably across multiple sites and customers.
• ST Telemedia Global Data Centers opened a new AI-ready data center campus in New Town, Kolkata, engineered with modular, high-density rack configurations and advanced cooling systems to support scalable AI compute deployment for colocation customers. Details are available at sttelemediagdc.com.

Segmentation Analysis

Analysis by Rack Type

Standard 19-inch racks held the largest market share in 2025 because they remain the default enclosure format across enterprise, colocation and cloud data centers, offering broad compatibility with existing server, networking and power equipment. Their established manufacturing base, lower unit cost and compatibility with widely deployed rack accessories make them the default starting point for most AI deployments that do not yet require full rack-scale GPU integration. Continued investment by legacy IT vendors in reinforced, higher-load variants of the 19-inch format is extending its relevance even as GPU density increases, particularly in enterprise and inference-focused deployments where extreme power densities are not yet required.

Open Rack Standard racks are projected to grow at the fastest CAGR during the forecast period, driven by hyperscale operators standardizing on the Open Compute Project's ORv3 specification to reduce vendor lock-in and simplify multi-supplier rack integration. ORv3 racks support higher-current busbars, larger power shelves and taller, deeper form factors suited to GPU-dense compute trays, making them the preferred format for next-generation NVIDIA GB200 and GB300 NVL72 deployments. Growing supplier participation from Legrand, Vertiv, Schneider Electric and nVent around the ORv3 specification is accelerating component availability and lowering deployment costs for adopters.

Rack Type categories include

                 ·           Standard 19-Inch Racks (Dominating Segment)

                 ·           Open Rack Standard (ORv3/OCP) Racks (Highest CAGR Segment)

                 ·           Blade Server Racks

                 ·           Micro Data Center Racks

                 ·           Others

Analysis by Cooling Type

Air-cooled racks held the largest market share in 2025 because the majority of the installed data center base, including enterprise and inference-focused facilities operating below 30 kW per rack, continues to rely on conventional hot-aisle and cold-aisle containment. Air cooling remains lower in upfront capital cost, requires no facility water loop, and is compatible with a wide base of existing IT equipment, making it the practical choice for operators not yet running the most GPU-dense AI training workloads. Its large installed base and simpler maintenance requirements continue to support steady, if slower, ongoing demand across the market.

Direct-to-chip liquid-cooled racks are projected to grow at the fastest CAGR during the forecast period as rack densities for AI training clusters routinely exceed 100 kW, a threshold beyond which air cooling becomes operationally and economically impractical. Cold plates mounted directly on GPUs and CPUs capture heat at the source, enabling significantly higher rack densities within the same physical footprint. Rising availability of coolant distribution units from Vertiv, Schneider Electric, nVent and Supermicro, combined with NVIDIA's liquid-cooled reference designs for its Blackwell and Rubin platforms, is accelerating adoption across hyperscale and colocation facilities.

Cooling Type categories include

                 ·           Air-Cooled Racks (Dominating Segment)

                 ·           Direct-to-Chip Liquid-Cooled Racks (Highest CAGR Segment)

                 ·           Immersion-Cooled Racks

                 ·           Rear-Door Heat Exchanger Racks

                 ·           Others

Analysis by Power Density

Racks operating below 20 kW held the largest market share in 2025 because this density band still covers the bulk of the global installed base, spanning enterprise IT, general-purpose cloud computing and non-GPU workloads that do not require specialized thermal management. These racks are supported by mature, low-cost power distribution and air-cooling infrastructure already deployed across most existing data center facilities. Their continued dominance reflects the gradual pace at which enterprise IT estates are being upgraded relative to the faster build-out of dedicated AI training infrastructure.

Racks operating above 100 kW are projected to grow at the fastest CAGR during the forecast period as hyperscale operators deploy NVIDIA GB200 and GB300 NVL72 systems that concentrate up to 72 GPUs within a single rack. Deloitte has noted that next-generation AI racks could reach densities of up to 370 kW during 2026, requiring purpose-built structural reinforcement, high-current busbars and dedicated liquid cooling loops. This density band is becoming the reference design point for new hyperscale AI data center campuses built specifically for large-scale model training.

Power Density categories include

                 ·           Below 20 kW per Rack (Dominating Segment)

                 ·           20 kW to 50 kW per Rack

                 ·           50 kW to 100 kW per Rack

                 ·           Above 100 kW per Rack (Highest CAGR Segment)

Analysis by Component

Rack enclosures and frames held the largest market share in 2025 because every AI rack deployment, regardless of cooling method or power density, requires a physical enclosure as its structural foundation. Enclosures represent a mandatory, high-volume line item across hyperscale, colocation and enterprise deployments, and reinforced, heavier-duty frame designs capable of supporting GPU trays weighing several thousand pounds are increasingly replacing standard-duty enclosures. This structural requirement, combined with steady replacement demand from an expanding installed base, keeps enclosures and frames the largest single component category in the market.

Cooling units and thermal management components are projected to grow at the fastest CAGR during the forecast period as coolant distribution units, rear-door heat exchangers and cold plates shift from optional add-ons to mandatory rack components for high-density AI deployments. Vendors including Vertiv, Schneider Electric, nVent and Rittal are rapidly expanding coolant distribution unit capacity, with Motivair by Schneider Electric now offering units scalable from 105 kW to 2.5 megawatts. This component category is capturing a disproportionate share of new rack-related capital spending as operators retrofit and build for higher densities.
