Hyperscale expansion to drive 4.8% relay rack market growth through 2035
A market forecast report by IndexBox projects the global relay racks market to grow at a 4.8% CAGR through 2035. The growth is primarily fueled by the expansion of hyperscale data centers, edge computing deployment, and the need for high-density, liquid-cooled infrastructure to support compute-intensive workloads like video streaming.
Key Takeaways
- Data centers and cloud infrastructure currently account for 38% of global relay rack demand.
- Addressable installed base for standard enclosures is projected to grow 40-60% over the next decade.
- Average rack depths are increasing to 1000-1200mm to accommodate dense GPU configurations.
- Static load requirements for new rack deployments now frequently exceed 2,000 lbs to support liquid cooling infrastructure.
Why It Matters
For streaming B2B providers, this growth signals a critical infrastructure shift toward high-density compute clusters necessary for AI-driven encoding and low-latency delivery. The market pivot from standard 42U racks to heavier, deeper, liquid-ready enclosures suggests that power and thermal management are now the primary bottlenecks in scaling streaming capacity. As hyperscalers like AWS and Google Cloud lead this transition, specialized hardware vendors must align production with regional assembly hubs to mitigate logistics inflation. Watch for a rise in premium, seismic-rated, and EMC-shielded enclosure sales as edge computing nodes move into less controlled, industrial environments.
Additional Context
The shift toward high-density infrastructure is already reflected in industry technical benchmarks. Per the AFCOM 2026 State of the Data Center Report, average rack density surged to 27 kW in 2026, a significant increase from 16 kW in 2025. This rapid rise is largely attributed to the integration of AI and high-performance computing (HPC) workloads, which require specialized enclosures capable of supporting liquid cooling systems. McKinsey reported in October 2024 that training models like ChatGPT can consume over 80 kW per rack, while high-end GPU configurations may reach 120 kW. Simultaneously, the liquid cooling market is experiencing a corresponding surge. Per Grand View Research, the global data center liquid cooling market was valued at $6.7 billion in 2025 and is projected to grow at a CAGR of 20.1% through 2033. Direct-to-chip cooling has emerged as the dominant segment, particularly for deployments exceeding 30 kW. Major hardware OEMs including Dell, Lenovo, and HPE have responded by offering liquid-cooled server SKUs as standard options as of August 2025. Capacity expansion remains aggressive among major colocation providers. Per S&P Global, Equinix and Digital Realty expanded their active project pipelines to a combined $9.8 billion by late 2025, a massive increase from $1.5 billion in 2021. Equinix alone delivered 23,250 new retail cabinets in 2025, according to its February 2026 earnings report. However, Uptime Institute's 2024 survey provided a reality check, noting that while hyperscale clusters are pushing extreme densities, 4 kW to 6 kW racks still represent the largest installed base for traditional enterprise facilities.
