Who owns Data Centers?
The majority of data center capacity is divided between Big Tech “hyperscalers” and specialized real estate/private equity firms.
1. Cloud & Tech Giants (Hyperscalers)
These companies build and own massive, customized campuses to support their own cloud services and AI workloads. Just four companies account for the majority of global hyperscale capacity.
- Amazon Web Services (AWS): Operates the largest portfolio of data centers globally.
- Microsoft Azure
- Google Cloud
- Meta Platforms
2. Commercial Real Estate & Private Equity
These are wholesale colocation companies that buy, build, and lease data center space to enterprises and the tech giants mentioned above. The leaders in this space include:
- Blackstone: The largest owner of data centers globally (through holdings like QTS and AirTrunk).
- Equinix: The largest retail colocation and interconnection provider.
- Digital Realty: A massive global real estate investment trust (REIT) specializing in carrier-neutral data centers.
