MGX Closes $49 Billion AI Fund in One of the Largest Raises on Record

UAE-based MGX has closed one of the largest artificial intelligence investment funds ever raised, locking in $49 billion in capital commitments. The fund counts OpenAI, Anthropic, and Elon Musk's xAI among its portfolio companies, with the xAI position established prior to that company's merger with SpaceX.

Scale on Record

At $49 billion, MGX's fund close ranks among the largest dedicated artificial intelligence vehicles ever raised. The number is the operative fact for capital allocators: a single fund, based in the UAE, has locked in a commitment to AI at a scale that few investment vehicles anywhere have matched. MGX's positions in major AI companies were already established going into the close, giving the fund an active portfolio rather than a dry-powder position. For portfolio managers tracking AI financing, a $49 billion close reshapes the conversation about where the largest pools of institutional capital are flowing and who controls them.

Portfolio Construction Across Competing Names

MGX's disclosed positions span major AI companies across different corners of the competitive landscape. The fund backs OpenAI and Anthropic — two of the most prominent companies in artificial intelligence — as well as xAI, the AI venture founded by Elon Musk. The xAI stake was built ahead of that company's merger with SpaceX. Holding simultaneous positions in competing AI companies reflects a category-level conviction rather than a concentrated single-name bet. That cross-portfolio construction is unusual for a vehicle of any size; at $49 billion, it is particularly notable.

Gulf Capital at the Frontier

The MGX close marks a consequential moment in the geography of AI investment. A raise of this magnitude from a UAE-based vehicle signals that frontier AI financing is no longer concentrated in any single geography or fund type. For the buy-side, a $49 billion close is not a soft signal — it establishes Gulf capital as a structural force in the sector, with a portfolio spanning some of AI's most closely watched names. The scale of the commitment makes the fund's directional conviction plain; the question now is where within the AI buildout those positions deliver the most return.
