The Artificial Intelligence Infrastructure Partnership (AIP), MGX, and BlackRock’s Global Infrastructure Partners closed their acquisition of Aligned Data Centers on July 20. The enterprise valuation: $40 billion. The seller: Macquarie Asset Management and its co-invest partners, who had held the company through its build-out phase.

The deal ranks as one of the largest private investments in digital infrastructure ever completed.

What They Bought

Aligned operates 51 campuses with more than 6.4GW of operational and planned capacity. Its footprint concentrates in Tier I digital gateway markets — Northern Virginia, Chicago, and other high-density interconnection hubs. Those locations matter: proximity to hyperscaler network exchange points reduces latency and negotiating leverage for tenants who depend on proximity to cloud onramps.

The 6.4GW figure includes both live capacity and projects under development. At current AI training densities — where a single large GPU cluster can consume 50-150MW — 6.4GW represents the infrastructure needed to run roughly 40-130 frontier training runs simultaneously.

The Consortium

Three distinct capital pools structured the deal:

AIP — the Artificial Intelligence Infrastructure Partnership — was formed specifically to deploy capital into AI infrastructure at scale, backed by sovereign wealth and institutional allocators focused on the AI buildout cycle.

MGX is the Abu Dhabi-based technology investment vehicle that has moved aggressively into AI compute infrastructure over the past 18 months, with investments spanning chipmakers, data center operators, and AI model labs.

BlackRock’s Global Infrastructure Partners manages over $100 billion in infrastructure assets globally and brings project finance expertise that sovereign vehicles typically lack.

The three-way structure pools capital from sovereign Middle Eastern investors, Western institutional infrastructure managers, and what amounts to a purpose-built AI infrastructure vehicle. It mirrors the model other large data center operators have used to separate development risk from operational cash flows — one entity builds, another holds long-term debt, a third takes the equity upside.

Context

The $40B valuation for Aligned puts it in the range of established hyperscale operators like QTS and CyrusOne at their acquisition peaks, but with a higher growth premium baked in. Macquarie’s exit crystallizes gains from a build cycle that preceded the current AI infrastructure gold rush.

For AIP and MGX, the Aligned acquisition secures control over a large, geographically distributed portfolio at a moment when data center construction timelines have stretched to 3-5 years due to power permitting backlogs, transformer shortages, and grid connection queues. Acquiring existing capacity skips that queue entirely.

The deal also puts sovereign capital from the Gulf directly inside US-based AI compute infrastructure, a structural shift in who owns the physical layer of AI that regulators will increasingly scrutinize.
