What it does

Abu Dhabi state-backed investment vehicle, launched in 2024 by Mubadala Investment Company and G42, that holds direct equity stakes in OpenAI, Anthropic and xAI and was a founding equity funder of the Stargate AI-infrastructure project.

Why it matters

MGX has become one of the most consequential single investors in frontier AI, with reported stakes in OpenAI, Anthropic and xAI plus a role funding the physical Stargate build-out -- giving the UAE outsized private-market exposure to how the AI race turns out.

How it makes money

Earns investment returns on its equity stakes in AI labs and infrastructure projects; as a state-backed vehicle, those returns ultimately accrue to its Abu Dhabi government backers.
