Revenue Model & Pricing
Digital Realty earns rent. Large customers sign multi-year wholesale leases for whole data halls or buildings measured in megawatts, while smaller customers take cabinets and cages under shorter colocation contracts (the company reports this as its 0-1 MW category). On top of rent it charges recurring interconnection fees for cross-connects between customers, carriers and cloud on-ramps. Utility power is largely billed back to tenants, and big development projects are increasingly funded through joint ventures and private funds in which Digital Realty keeps a minority stake and earns fees and promote income.

How Digital Realty Makes Money: FAQ
How does Digital Realty generate revenue?
Digital Realty generated $6.11 billion of revenue in FY2025, mainly from rent on hyperscale and colocation space, tenant power reimbursements and interconnection fees. 2026 revenue guidance is $6.85-$6.95 billion.
What is the difference between Digital Realty's Wholesale and Colocation business models?
Wholesale (Turn-Key Flex / Scale) leases large, dedicated megawatts of power and physical data hall space to hyperscalers on 5- to 15-year contracts. Colocation provides single cabinets, caged spaces, and shared power to enterprise clients on 1- to 3-year contracts with high interconnection density.
What is ServiceFabric and how does it generate interconnection revenue?
ServiceFabric is Digital Realty's software-defined interconnection platform. It allows enterprise customers to instantly spin up private, high-bandwidth virtual connections between multiple data centers, cloud providers, and SaaS networks worldwide, generating recurring subscription fees.
How does Digital Realty manage electrical power consumption and utility billing?
Digital Realty structures wholesale hyperscale customer contracts on a 'modified gross' or 'triple-net' pass-through basis. This means customers pay directly for the electricity their IT equipment and cooling consume, shielding Digital Realty's operating margins from power commodity price volatility.
What is 'Data Gravity' and how does Digital Realty monetize it?
Data Gravity is the phenomenon where large accumulations of enterprise and AI data attract applications, services, and cloud computing resources to the same physical location. Digital Realty monetizes this through PlatformDIGITAL, positioning its data centers as the essential nexus where data is stored and exchanged.
How does Digital Realty support high-density Artificial Intelligence (AI) workloads?
Digital Realty offers high-density halls with direct-to-chip liquid cooling for GPU clusters and participates in NVIDIA's DGX-Ready Data Center program.
What role do institutional joint ventures play in Digital Realty's capital strategy?
Partners such as Blackstone (hyperscale development JV), Brookfield Infrastructure (Ascenty) and TPG (a Northern Virginia JV) supply much of the capital for new campuses, while Digital Realty earns development and management fees and keeps a smaller stake.
What is the typical lease duration and customer retention rate at Digital Realty?
Hyperscale leases typically run many years while colocation contracts are shorter. Customers rarely move live infrastructure, and in Q2 2026 cash rents on renewals rose 25.4%.
How does Digital Realty make money?
They do not own the servers; they own the massive concrete buildings, the industrial HVAC cooling, and the massive electrical grid connections. They operate as a REIT, generating massive, highly predictable recurring revenue by leasing this ultra-secure physical space to tech giants (hyper-scalers) on 10-to-15 year contracts.
