The Data Center Joint Venture is the development vehicle formed in November 2023 by Realty Income and Digital Realty Trust to build two build to suit data centres in Northern Virginia, the largest data centre market in the world. Digital Realty contributes the development and operating platform and the client relationship, while Realty Income supplies most of the equity, an initial investment of roughly 200 million dollars, with each partner funding its share of the remaining costs. Construction began in the fourth quarter of 2022 and the first phase, budgeted at about 400 million dollars, delivered 16 megawatts of capacity in mid 2024 to a single investment grade client that pre leased the whole of both facilities before construction on a ten year lease with two percent annual escalators. The client can expand the sites to 48 megawatts in total, which would raise the budget towards 800 million dollars, and that second phase expansion was under way through 2025.

Data Center Joint Venture (with Digital Realty Trust, Inc.) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Digital Realty and Realty Income Form Build-to-Suit Data Center Development Joint Venture (Realty Income Form 8-K Exhibit 99.1, 13 November 2023, SEC), Realty Income Corporation Form 10-K for FY2025 (SEC) and Realty Income Form 8-K, 13 November 2023 (SEC). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Realty Income Corporation, as of 30 Jun 2026. Carrying amount of Realty Income's 80.0%-owned equity-method investment in a two-property data center joint venture, as of 30 Jun 2026 ($348,861,000, up from $293,073,000 at 31 Dec 2025 per the FY2025 10-K, same named entity, confirming continuity). The joint venture partner and the venture's operating client is Digital Realty Trust, Inc. (NYSE: DLR); Realty Income's holding is an equity interest in the joint venture entity itself, not shares of Digital Realty Trust the public company, so target_ticker is left null and target_is_private is true. Realty Income's pro-rata share of the venture's second development-phase costs was a separately disclosed $177.7 million unfunded commitment as of 30 Jun 2026, not included in the carrying amount above. sourcesource 2
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Data Center Joint Venture (with Digital Realty Trust, Inc.) where a holder stated one, and are missing where no holder did.
