MGX has raised roughly $50 billion for AI, and the real message is not subtle: the next compute boom is being financed by sovereign capital as much as Silicon Valley.
Abu Dhabi's MGX has closed a raise of nearly $50 billion, Axios reported, citing Bloomberg, pulling money from regional sovereign wealth funds, pension funds and large institutional investors. Fifty billion dollars for one purpose: buying into the chips, data centers and model companies that now sit underneath the AI economy. If you've been wondering who can still write checks big enough for this buildout, the answer is increasingly clear. It isn't only the hyperscalers.
MGX is just over two years old. Mubadala Investment Company and G42 launched it in March 2024 with a stated target of managing $100 billion in assets, and this raise gets it roughly halfway there. Axios said MGX has already written major checks into OpenAI, xAI and Anthropic, which tells you what kind of investor Abu Dhabi is trying to build here. Not a side fund. Not a branding exercise. A vehicle that can sit in the same room as SoftBank, BlackRock, Microsoft and Nvidia when the largest AI deals are carved up.
The numbers around those companies are absurd, but they are not decoration. The Guardian reported that OpenAI completed a $122 billion funding round this year at an $852 billion valuation, with Amazon, Nvidia and SoftBank among the major backers. Anthropic announced in February that it had raised $30 billion in a Series G at a $380 billion post-money valuation. Business Insider reported in January that xAI closed a $20 billion Series E, with investors including Qatar Investment Authority, MGX, Fidelity, Valor, Nvidia and Cisco Investments. If you want to understand MGX, start there. It has been buying into the companies that are consuming the most compute, not merely talking about it.
MGX describes its investing mandate across three areas: AI infrastructure, semiconductors and core AI technologies such as models, software, data, life sciences and robotics. That third bucket is the tell. A fund that only wanted exposure to the data center boom could stop at land, power contracts and fiber. MGX wants more than that. It wants a claim across the stack, from silicon and server farms to the labs training the models that will fill those machines.
The clearest proof is the Artificial Intelligence Infrastructure Partnership, the vehicle created by BlackRock, Global Infrastructure Partners, Microsoft and MGX, later joined by Nvidia and xAI. In October 2025, that group agreed to acquire Aligned Data Centers from Macquarie Asset Management in a transaction valued at about $40 billion, according to CNBC and other reports at the time. Aligned brought 5 gigawatts of operational and planned capacity across dozens of campuses in North and South America. One deal. Forty billion dollars. That is the scale you now need before anyone in AI infrastructure takes you seriously.
SoftBank's Stargate project is still the bigger number on paper. Announced in January 2025 with OpenAI, Oracle and MGX, it targets up to $500 billion in US AI infrastructure spending through 2029. Bloomberg reported at the time, citing The Information, that SoftBank and OpenAI were each expected to commit about $19 billion, while Oracle and MGX were expected to put in about $7 billion each. But Stargate is a single joint venture built around one national infrastructure push. MGX's new pool is different. It can move into a data center operator, a chip deal, a model company or the next financing round that suddenly becomes too large for ordinary venture capital.
Here's the thing: that makes MGX more important than a normal financial sponsor. Venture funds want exits. Public tech companies have shareholders watching quarterly capex. Sovereign-backed investors can hold longer, take strategic positions and tolerate the slow, expensive work of building compute. That is exactly why this money matters to Nvidia, OpenAI, Anthropic and the rest of the market. Training frontier models has become a capital problem as much as a research problem.
There is also a geopolitical edge here, and you shouldn't pretend otherwise. The UAE is not simply buying financial returns. It is buying influence over which companies get funded, which data centers get built, and which suppliers sit closest to the next generation of AI infrastructure. Abu Dhabi already has Mubadala, G42 and a growing roster of technology partnerships. MGX gives that strategy a dedicated investment arm with global reach and a very large checkbook.
MGX still needs roughly another $50 billion to reach its own $100 billion target. Given the speed of this raise, that gap no longer looks like the hard part. The harder question is where the money lands next, because in AI infrastructure, capital does not just follow power. Increasingly, it decides who gets access to it.
