BlackRock closes $40B Aligned Data Centers acquisition, commits $5B growth capital

A consortium led by BlackRock's Global Infrastructure Partners and Abu Dhabi's MGX closed the $40 billion acquisition of Dallas-based Aligned Data Centers on Tuesday, with an immediate $5 billion growth capital commitment. The deal marks the first deployment from the Artificial Intelligence Infrastructure Partnership, a vehicle that counts Microsoft among its backers and targets the physical layer beneath frontier compute.

Aligned operates 19 operational data centers across the United States, concentrated in Dallas, Phoenix, Salt Lake City, and Northern Virginia. The company runs roughly 1.5 gigawatts of live capacity and holds development rights for another 3 gigawatts, positioning it in the second tier of hyperscale providers behind Digital Realty and Equinix but ahead of most regional operators. The consortium structure—GIP, MGX, and the AI Infrastructure Partnership—creates a three-party governance model with Microsoft holding indirect influence through the Partnership vehicle without appearing on the cap table directly.

The $5 billion growth commitment points to accelerated construction timelines rather than geographic expansion. Aligned's development pipeline already sits on permitted land in existing metros, and the capital unlocks 18-24 month build cycles instead of the 30-36 month cadence typical for speculative capacity. Hyperscale tenants—Amazon Web Services, Google Cloud, Microsoft Azure—pre-lease in 100-200 megawatt blocks, and the consortium is banking on AI training demand to absorb new supply faster than the 12-15% annual growth rate data center REITs have modeled. The $5 billion covers roughly 500 megawatts of new capacity at current construction costs of $9-10 million per megawatt, assuming no cost overruns on electrical infrastructure.

MGX's participation formalizes Abu Dhabi's infrastructure sovereignty play. The fund manages over $100 billion and has co-invested with BlackRock on three prior energy transition deals since 2022, but this marks its first U.S. data center exposure. The GCC states are building compute as a geopolitical hedge, and MGX's board seat in the consortium gives Abu Dhabi visibility into U.S. hyperscale procurement cycles and power grid constraints. That intelligence feeds back into G42's data center buildout in the UAE, which is targeting 2 gigawatts of AI-optimized capacity by 2027.

The deal closed without meaningful regulatory scrutiny, despite the foreign sovereign participation. CFIUS reviewed the transaction in four months and cleared it without mitigation measures, a signal that data center infrastructure—even when tied to AI workloads—remains outside the tightening perimeter around semiconductor fabs and advanced hardware. That clearance speed matters for the next wave of consortium-led acquisitions. CyrusOne, CoreSite, and Switch remain potential targets for similar structures, and the Aligned precedent establishes that sovereign capital can move freely in U.S. hyperscale real estate.

Watch the Q3 2025 leasing velocity. Aligned's pipeline depends on AWS and Microsoft pre-leasing 60% of the new capacity before construction starts, and both hyperscalers have slowed new commitments in the past 90 days as they renegotiate power pricing with utilities. If Aligned announces a new 100+ megawatt lease in Phoenix or Northern Virginia by September, the growth capital deploys cleanly. If leasing stalls, the consortium will face the choice between building on spec—rare for private equity infrastructure—or slowing the construction cadence and redeploying capital into European or Asian metros where demand remains firmer.

The $40 billion enterprise value prices Aligned at roughly $27 million per live megawatt, a 20% premium to the Digital Realty trading multiple but in line with recent take-privates of QTS Realty and CoreSite. Sovereign buyers pay for control and future capacity, not current EBITDA.
