BlackRock, MGX Close $40B Aligned Deal, Commit $5B More

A BlackRock-led consortium just wrote another $5 billion cheque for a data centre platform it only closed on this week, and the composition of the buyer matters more than the size of the number. According to The National, the group finalised its $40 billion enterprise-value acquisition of Aligned Data Centres from Australian asset manager Macquarie Asset Management, and immediately committed another $5 billion to fund the company's expansion.

The consortium is BlackRock, Abu Dhabi's MGX, and the Artificial Intelligence Infrastructure Partnership, the vehicle set up to route sovereign and corporate money into AI build-out. Aligned brings 51 campuses and more than 6.4 gigawatts of operational and planned capacity spread across the usual US hyperscale gateways, northern Virginia, Chicago, Dallas, Ohio, Phoenix and Salt Lake City, plus Sao Paulo, Queretaro and Santiago in Latin America. Chief executive Andrew Schaap and the existing management team stay on, and the headquarters remain in Dallas.

Why this matters if you do not buy or build data centres: MGX is not a passive limited partner here. It is a private investment firm established in 2024, with Abu Dhabi's Mubadala Investment Company and AI and cloud firm G42 as partners, chaired by Sheikh Tahnoon bin Zayed, Deputy Ruler of Abu Dhabi and National Security Adviser. The same firm participated in Anthropic's $65 billion Series H round, and last year invested in OpenAI at a $300 billion valuation. Its MGX Fund I raised $49 billion, above its initial $45 billion target. Read together, the position is a top-to-bottom stack: sovereign capital into the frontier labs, and now the physical estate those labs will train and serve on. AIP's stated ambition, per the reporting, is to mobilise $30 billion of equity, with potential to reach $100 billion including debt financing.

The honest caveat is that "committed" is a checkbook figure, not a spade in the ground. The reporting does not break down how much of the $5 billion goes to new campuses versus densifying the existing 6.4 GW pipeline, which hyperscaler customers underwrite the expansion, or how the Latin America sites fit the roadmap. It also does not address the regulatory questions a Gulf-chaired consortium taking a US-anchored operator will raise with US tenants and reviewers.

What is worth watching is who benefits when this much capital lands in one platform at once. Aligned gets to bid for power interconnects and long-lead cooling gear while capital-constrained rivals wait their turn, and the consortium members get a US operating platform they can point their own compute demand at. The rest of the sector now has to price against a competitor whose cost of capital is not really a market rate.
