Digital Realty, one of the largest U.S. data-center landlords, is paying $3.5 billion in cash and stock to take full ownership of three fully leased facilities in Northern Virginia, buying out Blackstone's ownership stakes in a transaction that converts a 2023 development partnership into a sole-operator play.
The transaction covers two 96-megawatt campuses in Manassas and a third 96-megawatt site in Sterling, giving Digital Realty 288 megawatts of fully leased IT capacity previously shared with Blackstone-managed funds. At 100% ownership, the portfolio is valued at roughly $7.8 billion, a figure that includes assumed debt and the remaining development costs required to complete parts of the campuses. The gap between the $3.5 billion check and the $7.8 billion portfolio value puts most of the asset's worth in the long-dated leased cash flow rather than in the underlying real estate.
That gap is the deal's center of gravity. Digital Realty is paying for control of cash flow on assets whose value sits in the long-term leases already in place, a structure that turns the buyout from a development-phase partnership into something closer to an infrastructure-style hold.
The deal unwinds the U.S. leg of a 2023 joint venture in which Blackstone took majority interests and Digital Realty developed and operated hyperscale campuses across Northern Virginia, Paris, and Frankfurt. The European assets are not part of this transaction; the buyout does not change ownership there. What it changes is who holds the cash flow on the American portion of the joint venture, the large-scale facilities used by the major U.S. cloud and AI providers.
For Blackstone, the sale fits a pattern of the firm rotating out of operating assets toward newer development-phase capital — the kind of capital needed when sites were still being built and tenant commitments were being established. With the sites fully leased today, the sale represents a rotation in data-center economics — sponsors moving capital back toward development vehicles as the asset class matures. The framing is editorial rather than Blackstone-attributed, but it reflects how the market is shifting from sponsor capital during construction to operator ownership once leases lock in.
For Digital Realty, the rationale runs the other way. Once long-term tenants are locked in, operators, not financial sponsors, are best positioned to own the steady cash flow and capture the operating margin.
JLL's Data Center Outlook and McKinsey on AI workloads and hyperscaler strategies reach the same conclusion from the demand side. Both describe AI workload growth and hyperscaler capital expenditure as the dominant demand drivers for new capacity in Northern Virginia, pointing toward long-dated lease-backed structures rather than short-cycle real-estate plays. The Digital Realty-Blackstone transaction is not a vote on near-term AI compute demand; it is a vote on the maturity of the underlying asset class.
Three watch items follow. First, the per-megawatt implied valuation in this transaction will set a reference point for the next round of operator-sponsor buyouts in the Northern Virginia cluster, where data-center density sets the pricing. Second, the Paris and Frankfurt portions of the 2023 joint venture will draw attention as a separate test of whether the same consolidation logic travels outside the U.S. corridor. Third, future capacity additions will tell whether operators are buying back yield or also acquiring room to lease new tenants, a distinction that determines whether the deal is defensive consolidation or the leading edge of another lease-up cycle.
The transaction is expected to close on June 30, alongside Blackstone's press release on the asset transfer and trade coverage from Data Center Dynamics that confirms the three-site structure and the ~$7.8 billion at-100% valuation.
