MGX: AI Investment and Stargate Equity Participation

Investment across the AI stack

MGX was announced in March 2024 as an Abu Dhabi technology investment company. Its stated areas span data centers and connectivity, semiconductors, and AI technologies and applications. This is an investment mandate across the resources and businesses supporting AI. [1]

MGX was one of four initial equity funders named in the January 2025 Stargate announcement. The source identifies the financial participants while distinguishing SoftBank's financial responsibility and OpenAI's operational responsibility for the venture. [2]

Stargate's intended $500 billion investment over four years was a program target, rather than a disclosed MGX check of that size. The announcement supports MGX's participation in financing the buildout without making it the developer of every campus or the owner of the model provider. [2]
