PIF’s Humain invests $3bn in Elon Musk’s xAI prior to SpaceX acquisition

Saudi Arabia’s sovereign wealth fund, Public Investment Fund (PIF), through its AI-focused subsidiary Humain, has invested $3 billion in xAI, the artificial intelligence company founded by Elon Musk. The investment comes ahead of a reported acquisition involving SpaceX, signaling a deepening strategic alignment between AI development and advanced aerospace technologies.

The move underscores PIF’s ambition to position Saudi Arabia as a global hub for artificial intelligence and next-generation technologies. By backing xAI, Humain gains exposure to cutting-edge large language models and AI infrastructure, while potentially strengthening technological ties with Musk’s broader ecosystem of companies.

The timing is significant, as xAI continues to expand its compute capabilities and integrate its models across Musk-linked platforms. The investment also reflects growing sovereign interest in foundational AI companies as geopolitical and economic competition around advanced AI intensifies.
