BlackRock's Global Infrastructure Partners, Abu Dhabi's MGX, and the Asian Infrastructure Partnership closed a $40 billion acquisition of Aligned Data Centers on Tuesday, immediately committing an additional $5 billion to expand hyperscale capacity across the company's existing portfolio. The consortium—which includes participation from Microsoft's Climate Innovation Fund—now controls one of North America's largest vertically integrated datacenter platforms at a valuation 38% above the prior record set by KKR's CyrusOne take-private in 2021.
Aligned operates 1.4 gigawatts of critical IT capacity across twelve campuses in Texas, Arizona, Utah, and North Carolina. The company's patented liquid cooling systems and modular construction approach position it for the high-density workloads generative AI models require, a factor the consortium cited in post-close statements. Microsoft's stake—disclosed at under 5% but structurally protected through board observation rights—grants the cloud provider priority capacity access under terms that predate the transaction. The deal values Aligned's existing contracts at roughly $28,500 per kilowatt of deployed capacity, a 22% premium to public datacenter REITs on a forward basis.
The $5 billion expansion capital represents the largest committed growth envelope announced alongside any datacenter acquisition. GIP's co-head of infrastructure noted the funds will finance 400 megawatts of net new capacity over eighteen months, concentrated in three existing campuses where power and fiber infrastructure already permits expedited deployment. Abu Dhabi's MGX—established in March 2024 with a $100 billion technology mandate—positions the deal as its anchor infrastructure holding, linking AI compute sovereignty with tangible physical assets. AIP's role bridges GIP's Western LPs and MGX's capital, a structure that mirrors the consortium's $30 billion Brookfield renewables partnership finalized in October.
The timing matters. U.S. datacenter vacancy rates fell to 2.8% in Q4 2024, the lowest on record, while average wholesale power costs climbed 19% year-over-year across primary markets. Aligned's existing PPAs lock in electricity at rates $11-$14 per megawatt-hour below current spot in ERCOT, delivering embedded margin expansion as hyperscale tenants renew leases negotiated before the generative AI buildout began. The consortium inherits contracts with $6.2 billion in backlog through 2028, approximately 68% tied to the four largest U.S. cloud providers.
Allocators should track three developments over the next six months. First, GIP's infrastructure fund will likely raise a successor vehicle targeting $30-$35 billion by mid-2025, using Aligned's contracted returns as the anchor case study. Second, watch for MGX to announce co-investment rights on future GIP deals above $10 billion, formalizing the capital partnership beyond one-off transactions. Third, permitting timelines in Arizona and North Carolina—where Aligned plans 180 megawatts of the expansion—face grid interconnection backlogs now averaging fourteen months, a constraint that could delay the committed deployment or force geographic reallocation.
Microsoft's shadow position carries forward-looking weight. The company holds matching rights on any future equity dilution and maintains veto authority over asset sales in markets where it leases more than 100 megawatts. That structural lock effectively gives Redmond control over the consortium's exit optionality in Texas and Arizona, the two regions accounting for 61% of Aligned's current NOI.
