Market Size & Share

Market Dynamics

KEY MARKET TREND:

Shift Toward Inference-Optimised, Liquid-Cooled Rack-Scale Architecture Emerging as a Transformational Trend

• Cloud providers are re-architecting fleets around rack-scale accelerated systems rather than individual servers, integrating compute, memory, interconnect and cooling as a single deployable unit so that large model training and high-volume inference can be provisioned as a standard product line.
• Direct-to-chip and immersion liquid cooling are replacing air cooling in new AI halls because accelerator racks now draw several times the power of conventional cloud racks, making thermal design a primary constraint on how much saleable capacity an operator can bring online per site.
• Inference is becoming the dominant recurring workload as enterprises move pilots into production, pushing providers to offer tiered serving options, token-based pricing, model routing and caching layers that optimise cost per output rather than raw training throughput.
• BloombergNEF estimated that more than 23 gigawatts of data centre IT capacity was under construction globally at the end of September 2025, with roughly three quarters of that pipeline located in the United States, indicating the scale of purpose-built AI capacity entering the market.

KEY MARKET DRIVER:

Record Hyperscale Capital Expenditure on Accelerated Compute is Driving Market Growth

• Hyperscale cloud operators are the primary buyers of AI infrastructure, and their multi-year capacity commitments convert directly into demand for accelerators, AI servers, high-bandwidth networking, storage and power infrastructure across the value chain.
• Enterprise adoption of generative and agentic AI is moving from experimentation to production deployment, creating sustained demand for reserved capacity rather than opportunistic on-demand usage, which improves revenue visibility for infrastructure providers and justifies further build-out.
• Persistent scarcity of power-ready sites, grid interconnection and advanced packaging capacity is keeping utilisation and pricing firm, encouraging operators to pre-commit capital years ahead of delivery and to secure long-term supply agreements with chip and equipment vendors.
• BloombergNEF reported that capital expenditure of the 14 largest publicly owned data centre operators is expected to approach USD 750 billion in 2026, against a little under USD 450 billion in the prior year, underlining the scale of committed investment in AI-ready capacity.

KEY MARKET OPPORTUNITY:

Sovereign AI Cloud Programmes and Regional Compute Capacity Creating New Revenue Streams

• National and regional AI compute programmes are creating a publicly underwritten demand channel that operates independently of enterprise IT budgets, giving infrastructure vendors and operators access to long-duration, policy-backed contracts.
• Regulated sectors including government, defence, healthcare and financial services represent an under-served segment that requires in-country data residency, audited supply chains and dedicated tenancy, which commands premium pricing relative to standard public cloud capacity.
• Emerging markets with favourable power costs and land availability are positioning as regional AI hubs, creating opportunities for equipment vendors, cooling specialists and managed service partners to establish early positions in new geographies.
• The European Commission and the EuroHPC Joint Undertaking launched the AI Gigafactories call for tenders on 30 July 2026 to select up to seven AI computing infrastructures across EU Member States, with bidding closing on 12 November 2026 and a targeted mobilisation of more than EUR 30 billion in combined public and private investment.

Segmentation Analysis

Analysis by Component

Hardware held the largest market share in 2025 because accelerators, AI servers, high-bandwidth memory, storage arrays, interconnect fabrics and power and cooling equipment account for the majority of upfront capital deployed in every AI cloud build. Each new training or inference cluster requires a fixed hardware footprint before any software or service revenue can be recognised, which concentrates spending in this component. Sustained accelerator scarcity and premium pricing have kept hardware value share elevated, while shortened refresh cycles drive repeat purchases.

Services are projected to grow at the fastest CAGR during the forecast period as enterprises shift from buying capacity to buying outcomes. Managed AI cloud services, capacity reservation and scheduling, model deployment support, fine-tuning pipelines, observability and compliance assurance are becoming essential because most enterprises lack in-house expertise to operate large accelerator clusters efficiently. Regulated industries increasingly require documented controls and residency guarantees that only managed offerings provide.

Component categories include

                 ·           Services (Highest CAGR Segment)

                 ·           Software

Analysis by Infrastructure Type

Compute infrastructure held the largest market share in 2025 because GPU and custom accelerator capacity is the binding constraint on every AI workload, and providers prioritise it above all other elements when allocating capital. Training runs for large models require tens of thousands of tightly coupled accelerators, while production inference requires continuously available serving capacity, so compute absorbs the bulk of both initial and incremental spending. High unit prices for advanced accelerators and constrained advanced packaging supply have reinforced this concentration.

Power and cooling infrastructure is projected to grow at the fastest CAGR during the forecast period because accelerator rack densities have risen sharply and conventional air-cooled designs can no longer dissipate the heat generated. Direct-to-chip liquid cooling, coolant distribution units, high-voltage busways and on-site power solutions are now mandatory in new AI halls rather than optional upgrades. Grid interconnection delays are pushing operators toward behind-the-meter generation and energy storage.

Infrastructure Type categories include

                 ·           Power & Cooling Infrastructure (Highest CAGR Segment)

                 ·           Networking Infrastructure

                 ·           Storage Infrastructure

Analysis by Deployment Model

Public cloud held the largest market share in 2025 because it offers immediate access to the newest accelerator generations without capital commitment, which suits the experimentation and scaling patterns of most enterprise AI programmes. Hyperscale providers concentrate the largest contiguous clusters, the broadest model catalogues and the deepest tooling ecosystems, making public environments the default starting point for training and early production workloads.

Hybrid cloud is projected to grow at the fastest CAGR during the forecast period as organisations seek to keep sensitive training data and proprietary model weights within controlled environments while retaining elastic access to public capacity for peak training demand. Data protection rules, sector-specific supervisory expectations and sovereignty requirements are pushing regulated industries toward split architectures.

Deployment Model categories include

                 ·           Public Cloud (Dominating Segment)

                 ·           Hybrid Cloud (Highest CAGR Segment)

                 ·           Private & Dedicated Cloud

Analysis by Workload

Training held the largest market share in 2025 because frontier and enterprise model development consumes very large, tightly coupled accelerator clusters for extended continuous periods, generating high revenue per contract. Model providers and large enterprises commit to multi-year capacity agreements to secure the scale required for pre-training and large-scale fine-tuning, and these commitments dominate reported cloud backlog. Training also requires the most advanced interconnect and memory configurations, which carry premium pricing.

Inference is projected to grow at the fastest CAGR during the forecast period because every deployed application generates continuous serving demand that scales with user adoption rather than with model development cycles. As agentic and multimodal applications move into production, token volumes rise faster than training compute, and providers are expanding inference-optimised fleets, tiered serving options and cost-per-token pricing to capture it.
