Colocation data center companies

The colocation data center market is poised for significant expansion, projected to grow from approximately USD 76.5 billion in 2024 to over USD 140.8 billion by 2031, registering a CAGR of 12.4% during the forecast period. This surge is being propelled by the rising need for scalable IT infrastructure among enterprises seeking cost-effective alternatives to building in-house data centers.

A critical trend driving this momentum is the increasing adoption of hybrid cloud models, which colocation facilities support through direct cloud on-ramps and interconnection services. The demand for edge data centers is also surging, especially in industries such as telecom, finance, and e-commerce. Moreover, green data center initiatives are becoming a key market differentiator, opening opportunities for providers focused on energy efficiency and renewable-powered infrastructure.
