BlackRock’s CEO, Larry Fink, said on Thursday, January 15, that the company has raised $12.5 billion so far for its AI investment partnership with Microsoft and MGX.

The partnership was made in 2024, with BlackRock aiming to raise $30bn in equity and up to $70bn in debt financing.

Speaking during BlackRock’s Q4 2025 earnings call, Fink said: “Our AI partnership … continues to attract significant capital. AIP has raised over $12.5bn from partnership founders and clients.”

Others involved in AIP besides Microsoft and MGX include Nvidia and xAI.

The Global AI Infrastructure Investment Partnership was made to focus on data center and energy infrastructure projects, specifically to support AI. At the time of announcing the fund, Fink said that the partnership would “unlock a multi-trillion-dollar long-term investment opportunity.”

The partnership previously invested in the $40bn deal to acquire Aligned Data Centers in October 2025, the biggest acquisition deal in the digital infrastructure space to date.

In November 2025, BlackRock’s GIP (separate from the AI Investment Partnership) teamed up with ACS to form a €2bn ($2.33bn) joint venture to build and manage data centers. The JV will oversee the existing ACS digital infrastructure pipeline, which consists of data center schemes in the US, Europe, Asia, and Australia, with a projected capacity of 1.7GW.

Other recent investments pertinent to the data center industry include cooling firm Xnrgy, UK developer Gravity Edge, and chip company Groq.
