Saudi’s HUMAIN, a PIF AI company, invested USD 3 billion in xAI’s Series E round. This comes prior to xAI’s acquisition by SpaceX. As a result of the transaction, HUMAIN became a significant minority shareholder, with its xAI holdings converted into SpaceX shares.

“This investment reflects HUMAIN’s conviction in transformational AI and our ability to deploy meaningful capital behind exceptional opportunities where long-term vision, technical excellence, and execution converge,xAI’s trajectory, further strengthened by its acquisition by SpaceX, one of the largest technology mergers on record, represents the kind of high-impact platform we seek to support with significant capital,”

Tareq Amin, CEO of Humain

 The investment builds on HUMAIN and xAI’s 500MW AI infrastructure partnership in Saudi Arabia. This was a partnership announced between Humain and xAI in November 2025 in the U.S.-Saudi Investment Forum. Both firms had agreed that they would jointly develop 500 megawatts of AI data center infrastructure to deploy xAI’s Grok models in Saudi Arabia. 

xAI

According to the Saudi AI firm, the combination of xAI’s advanced AI capabilities with SpaceX’s scale, infrastructure, and mission-driven engineering creates a platform for accelerated growth, deep technological integration, and long-term value creation.

Looking ahead, HUMAIN’s strategy includes the pursuit of additional investments across artificial intelligence, frontier technologies, and critical infrastructure.

Previously, in January, xAI raised USD 20 billion in an upsized Series E funding round. With the investment, it sought out to ramp up deployment of new models and infrastructure ‌ to get ahead of competitors OpenAI and Anthropic. One month after the fundraiser, Musk’s SpaceX acquired xAI in a massive consolidation move. This move combines the billionaire’s artificial ​intelligence startup ‌with his space and rocket firm.
