# Abu Dhabi's MGX Closes Nearly $50 Billion to Bankroll the AI Buildout > Source: > Published: 2026-07-01 06:16:33+00:00 *MGX just closed one of the largest AI-only funds ever raised, and it still wants to double it.* Abu Dhabi's MGX has closed a raise of roughly $50 billion, according to Bloomberg and Axios, pulling commitments from regional sovereign wealth funds, global pension funds and large institutional investors. Fifty billion dollars raised for one purpose: buying up the chips, the data centers and the equity stakes that make up the AI economy. If you've been trying to figure out where the money for the next wave of compute is actually coming from, this is the answer, and it isn't Silicon Valley. MGX is barely two years old. Mubadala Investment Company and G42, the Abu Dhabi AI conglomerate, launched it in March 2024 with a target of managing $100 billion in assets. This raise gets it roughly halfway there, and it already has a portfolio to show for the ambition. MGX holds stakes in OpenAI, which closed a $122 billion round in March 2026 at an $852 billion valuation with SoftBank, Amazon and Nvidia also writing checks. It backed Anthropic through a $30 billion Series G in February and a subsequent Series H that valued the company near $965 billion. And it was one of the investors, alongside the Qatar Investment Authority, in xAI's $20 billion Series E. None of that is passive money. MGX has organized its new capital around three buckets: AI infrastructure such as data centers and connectivity, semiconductors including chip design and manufacturing, and what it calls core AI technologies, meaning models, software, data, life sciences and robotics. That third category is the tell. This isn't a fund that wants to be a limited partner sitting quietly behind other people's deals. It wants a seat at the table across the whole stack, from the silicon to the model weights. The clearest evidence of that ambition sits inside the AI Infrastructure Partnership, the vehicle MGX built with BlackRock, BlackRock's Global Infrastructure Partners, Microsoft and, more recently, Nvidia and xAI. In October 2025 that partnership agreed to buy all the equity in Aligned Data Centers from Macquarie Asset Management, a deal that valued Aligned at roughly $40 billion. That's a single transaction bigger than most sovereign wealth funds' entire AI allocation, and it happened before this latest $50 billion raise even closed. SoftBank's Stargate project is still the larger number on paper. Announced alongside OpenAI in January 2025, it targets up to $500 billion in US AI infrastructure spending through 2029, with SoftBank and OpenAI each putting in $19 billion at the outset and Oracle and MGX each contributing $7 billion. But Stargate is a single joint venture chasing one buildout in one country. MGX's new $50 billion isn't earmarked for a single project. It's dry powder the fund can point at chips in Taiwan, data centers in Texas, or the next foundation model raise, whichever moves fastest. BlackRock's own AI Infrastructure Partnership has raised $12.5 billion toward a stated target of $30 billion in equity and up to $70 billion in debt financing, per BlackRock chief executive Larry Fink. Layer MGX's $50 billion, SoftBank's Stargate commitments and BlackRock's partnership together and you get a rough picture of where the next couple hundred billion dollars in AI infrastructure spending is actually going to originate: not from venture funds, and not primarily from the hyperscalers' own balance sheets, but from sovereign capital and the asset managers willing to structure deals around it. Frankly, that's the more important story than the headline number. Nvidia, OpenAI and the hyperscalers need capital partners who can write nine and ten figure checks without blinking and who don't need liquidity back in three years. Sovereign wealth funds fit that profile better than almost anyone else in the market, and Gulf states have been explicit that AI is now a strategic priority on par with energy. The UAE isn't just buying returns with this money. It's buying leverage inside deals that will shape which chips get built, which data centers get powered, and which labs get funded next. MGX still needs roughly another $50 billion to hit its own $100 billion target. Given how fast it closed this round, that gap probably won't last long. **Also read:** [ITG Priced Its Nasdaq IPO Below Range Even as the AI Infrastructure Boom Rages On](https://startupfortune.com/itg-priced-its-nasdaq-ipo-below-range-even-as-the-ai-infrastructure-boom-rages-on/) • [Wayve's employees can now cash out at an $8.5 billion valuation](https://startupfortune.com/wayves-employees-can-now-cash-out-at-an-85-billion-valuation/) • [Anthropic launches Claude Sonnet 5 to bring near-Opus performance to developers at a fraction of the cost](https://startupfortune.com/anthropic-launches-claude-sonnet-5-to-bring-near-opus-performance-to-developers-at-a-fraction-of-the-cost/)
