Sheikh Tahnoon bin Zayed chairs a two-year-old firm that already ranks alongside the world's most consequential AI investors. MGX, the Abu Dhabi investment vehicle backed by Mubadala and G42, has closed Fund I at $49 billion — above its $45 billion target — drawing capital from institutional and private investors across the Gulf, North America, Asia, and Europe.
The fund is one of the largest ever dedicated to artificial intelligence. For context, AI companies globally have raised $416.6 billion so far in 2026, nearly double the figure for all of 2025, according to Dealroom. MGX has already deployed a portion of its new capital across 14 companies spanning the full AI technology stack.

The portfolio reads like a who's who of the AI frontier. MGX co-led OpenAI's $122 billion round in March, participated in Anthropic's $65 billion Series H in May, and backed Elon Musk's xAI in January before its merger with SpaceX. It also holds stakes in Binance, TikTok's US operations, and Khazna, alongside data centre assets through Vantage.
Infrastructure is where the strategy gets physical. In October 2025, MGX joined BlackRock's Global Infrastructure Partners to acquire Aligned Data Centres in a $40 billion deal — one of the largest private equity digital infrastructure transactions on record. In June, it expanded a partnership with Bpifrance, Mistral AI, and Nvidia to build what could become Europe's largest AI campus near Paris, with planned capacity reaching 3 GW of nationwide compute power.
What the $49B fund means for private markets
MGX targets over $100 billion in assets under management and plans to deploy up to $10 billion annually. That trajectory matters beyond the fund's own numbers. A state-backed vehicle of this scale, operating with a conventional GP-LP structure and investing across semiconductors, data centres, and frontier models, changes the competitive dynamics of private AI investing. Sovereign wealth is no longer a passive LP in AI — it is becoming the lead investor.
For limited partners evaluating private market allocations, the signal is unambiguous: the cost of owning frontier AI exposure is rising, and the most attractive opportunities are being placed in vehicles that few traditional fund managers can match on check size or access.
