Digital Realty (NYSE: DLR) announced June 29 that it had agreed to acquire Blackstone’s interest in three Northern Virginia hyperscale data centers, paying $3.5 billion in total consideration, $1.2 billion in cash and $2.3 billion in Digital Realty common stock. The assets are two 96 MW facilities in Manassas, Virginia, where Blackstone held an 80% stake, and one 96 MW facility in Sterling, Virginia, where Blackstone held 50%. Combined, the transaction transfers a blended 64% equity interest and 288 MW of IT capacity to Digital Realty.
Why it matters
The structure of this deal is more interesting than its headline number. Digital Realty isn’t paying $3.5 billion for a cluster of speculative shells, it’s paying for three assets that, according to the companies’ announcement, are fully leased to three unnamed investment-grade hyperscale customers under 15-year contracts with 3.6% annual rent escalators. Full occupancy. Long-dated contracts. The buyer knew exactly what it was getting.
The catch is what you don’t see: the tenant names. “Three investment-grade hyperscale customers” is the entire disclosure. That language is intentional, confidentiality is standard in wholesale colocation, and at this scale the universe of plausible tenants is small. Don’t expect that gap to be filled in any public filing.
The real story is the ownership structure Digital Realty is choosing. Joint ventures let REITs access capital while managing balance sheet exposure, but they also limit operational control and complicate future asset decisions. Buying out the partner, at a cash-plus-stock premium, says something specific: Digital Realty believes full ownership of these assets is worth more than the capital flexibility the JV provided. That’s a conviction bet on Northern Virginia’s position in the AI compute buildout.
Context
Northern Virginia is the largest data center market in the world by installed capacity, and it hasn’t stopped growing. The Manassas and Sterling corridors sit at the intersection of available power, fiber density, and proximity to federal and hyperscaler tenants. Assets there don’t trade often, and when they do, they don’t trade cheap. This deal is consistent with a pattern visible across the infrastructure market this quarter: institutional capital is moving from partnership structures into outright ownership of operating AI infrastructure, concentrating control of critical compute capacity in fewer hands.
The companies’ announcement projects an initial stabilized cap rate of over 6.5% once all three facilities reach full operational maturity. Per company guidance, two of the three assets are expected to stabilize in the first half of 2027, with the third following in early 2028. Those are projections, not locked outcomes, cap rate realization depends on the stabilization events actually closing on schedule.
One number that needs its qualifier: the companies describe a $7.8 billion gross asset value for the three-facility portfolio. That figure includes assumed project-level debt and remaining development capital expenditure. It is not the purchase price. The $3.5 billion consideration represents Blackstone’s blended 64% equity stake, not the total portfolio value.
What to watch
Watch whether the stabilization timeline holds. Two facilities targeting H1 2027 and one targeting early 2028 means Digital Realty is managing a phased integration while carrying $2.3 billion in newly issued stock on its balance sheet. If power permitting or construction delays push either facility past its stabilization window, the projected 6.5%+ cap rate moves further into the future, and the equity dilution the stock consideration created looks more expensive in hindsight. Q3 and Q4 earnings calls are the first real checkpoints.
What to Watch
TJS synthesis
This transaction won’t be the last of its type. The JV-to-full-ownership conversion is becoming a recognizable pattern in AI infrastructure: partners who entered colocation ventures during the build-out phase are now being bought out at premiums that reflect the scarcity of operating, fully leased hyperscale capacity. For infrastructure investors, the signal isn’t just the $3.5 billion, it’s that Digital Realty judged the cost of full ownership to be lower than the cost of remaining a partial stakeholder in assets this strategically positioned. Watch whether other REITs with minority JV positions in Northern Virginia follow the same playbook before year-end.
