Digital Realty

History and Founding

Digital Realty was formed in 2004 by the private investment firm GI Partners, which contributed 21 data centers acquired through bankruptcy auctions and distressed purchases. The company went public via an IPO in November 2004 on the New York Stock Exchange under the ticker DLR. Over the following years, Digital Realty expanded aggressively through portfolio acquisitions in key US markets such as Phoenix, Massachusetts, Connecticut, Atlanta, San Francisco, and Minnesota. Notable transactions include the 2015 acquisition of Telx for $1.886 billion, which significantly boosted its interconnection services, and the 2017 acquisition of DuPont Fabros Technology, a major move in the wholesale data center space. In Europe, the company acquired eight data centers from Equinix for $874 million in 2016. The company’s headquarters moved to Austin, Texas, and it now operates over 300 data centers across 55+ metropolitan areas in more than 25 countries.

Business Model and Revenue

Digital Realty operates as a real estate investment trust (REIT), generating revenue primarily through leasing data center space and providing interconnection services. Its carrier‑neutral model allows customers to connect with multiple carriers, cloud providers, and partners within a single facility, reducing latency and cost. The company’s strategy centres on expanding its global footprint through organic development and strategic acquisitions, while pursuing a “pervasive data architecture” approach. For 2022, Digital Realty reported $4.69 billion in revenue and $2.47 billion in net income, with total assets of $153.32 billion. The company also reports Funds From Operations (FFO) as a key metric; in Q4 2025, FFO per share was $1.89.

Key Products and Platforms

Digital Realty’s flagship platform is PlatformDIGITAL®, which delivers scalable colocation, secure interconnection, and a methodology for scaling digital business, supporting AI, hybrid cloud, and network use cases. The company offers flexible colocation products ranging from single racks to private suites and high‑density AI workflows, all backed by over a decade of 99.999% uptime. ServiceFabric® provides on‑demand connectivity services, including ServiceFabric® Connect for private interconnection within PlatformDIGITAL® hubs. Other connectivity solutions include Campus Connect, Metro Connect, Cross Connect, Internet Exchange, and IP Bandwidth. The company also offers an AI Infrastructure Solution Program, with partner‑validated private AI pod packages from Lenovo and ePlus, designed to reduce design cycles and accelerate AI pilots into production.

Recent Developments and Strategic Direction

In Q4 2025, Digital Realty signed $400 million annualised GAAP rental revenue bookings at 100% share, with a backlog of $817 million. The company launched its private capital strategy with the Digital Realty DC Partners NA Fund, targeting $3.25 billion for US‑focused investments. A major partnership was announced in 2024 with Blackstone for a $7 billion hyperscale data center development joint venture, with Digital Realty retaining a 20% interest. On the sustainability front, the company has signed over 1 GW of wind and solar contracts and is committed to the Climate Neutral Data Center Pact goal of net‑zero by 2030. These moves position Digital Realty to capitalise on growing demand for AI and cloud infrastructure.
