Abu Dhabi's MGX closes $50B AI infrastructure fund; targets $100B AUM

Abu Dhabi-based investment firm MGX has closed a $50 billion fund raise from regional sovereign wealth funds, global pension funds, and institutional investors, marking one of the largest capital pools ever dedicated purely to artificial intelligence infrastructure and technology. The fund, which closed in recent weeks, targets total assets under management of over $100 billion and plans to deploy approximately $10 billion annually in AI-related investments. MGX is backed by Mubadala Investment Company ($385B sovereign wealth fund) and G42, with Sheikh Tahnoun bin Zayed Al Nahyan as board chair and Khaldoon Al Mubarak as vice chair.

MGX's portfolio already spans the entire AI stack: it holds minority stakes in three of the four major frontier AI labs (OpenAI, Anthropic, and xAI), invests in semiconductor infrastructure (including chips for AI), operates data center joint ventures with BlackRock, Microsoft, and Nvidia (targeting $30B+ in capacity), and is actively pursuing the acquisition of DayOne, a Singapore-based data center operator spanning Southeast Asia, Hong Kong, Japan, and Finland. Notably, MGX is the only investor globally with exposure to all three major API-backed model companies, positioning it at the center of the commercial AI race regardless of architectural winners.

For infrastructure architects, MGX's capital deployment signals that multi-billion-dollar data center deals, chip manufacturing partnerships, and compute platform buildouts are now underway at sovereign-wealth scale. The fund's $500M minimum check size means smaller teams should expect consolidation pressure; sole proprietors of mid-market data center or semiconductor assets should anticipate acquisition inquiry. The $10B annual deployment rate implies that MGX will likely be a co-investor in every mega-deal above $2B in the AI infrastructure space for the next decade.
