Digital Realty Trust, Inc.'s Growth & Acquisition Strategy

Growth rests on three levers: delivering AI-ready, liquid-cooling-capable capacity on land it already controls (the 10-K cited more than 3,500 MW of potential future capacity); recycling capital through partnerships such as the 2023 Blackstone development joint venture and its private-fund platform; and expanding the higher-margin 0-1 MW and interconnection business, which signed a record $108M of annualized rent in Q2 2026.

How Digital Realty Trust, Inc. Makes Money

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.
