Who owns Blackstone joint venture (EMEA)

Blackstone joint venture (EMEA) - Profile

This is the European side of a hyperscale data centre development venture that Digital Realty and Blackstone announced in December 2023, covering four campuses across Frankfurt, Paris and Northern Virginia at a total estimated development cost of about 7 billion dollars. The venture builds shell and core data centre capacity leased to large cloud and artificial intelligence customers, with roughly 10 buildings planned and about 500 megawatts of IT load at full build out. Blackstone funds supply the bulk of the equity while Digital Realty contributes the land and existing development pipeline and runs the construction programme and day to day operations for a fee. Digital Realty reports the Frankfurt and Paris campuses in this venture within its EMEA segment, separately from the Northern Virginia campus.

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.

• Digital Realty Trust, Inc., as of 30 Jun 2026. 10-Q Note 5 footnote (1): 'Blackstone (50%)' within the combined Americas balance. This is a distinct entity from the separately disclosed EMEA-region Blackstone joint venture at 20% (see that row); the filing names both partners 'Blackstone' without further disambiguation, and Digital Realty's own FY2025 10-K MD&A references cash contributions from a Blackstone joint venture of approximately $707 million during 2024. Combined-balance trap, value left null. sourcesource 2
• Digital Realty Trust, Inc., as of 30 Jun 2026. 10-Q Note 5 footnote (3) to the EMEA region balance ($269,375 thousand at 30 Jun 2026): 'Blackstone (20%)'. Distinct from the Americas-region Blackstone JV at 50% above; the 10-K MD&A references retaining a 20% interest in the second phase of a Frankfurt/Northern Virginia-focused joint venture with Blackstone after receiving approximately $385 million of net proceeds from a contribution. EMEA balance is combined across three named entities (Blackstone, Medallion, Mivne); none individually sized. Combined-balance trap, value left null. sourcesource 2
