Saudi Arabia’s HUMAIN invested $3 billion in xAI’s Series E round just before the artificial intelligence company was acquired by SpaceX, positioning it at a pivotal stage in its platform scaling. As part of this transaction, HUMAIN became a significant minority shareholder in xAI, with its holdings converting into SpaceX stock following the merger, providing exposure to long-term stock price appreciation. This investment builds on HUMAIN’s previously announced 500MW AI infrastructure partnership with Saudi Arabia’s xAI, strengthening its role as both a strategic development partner and global investor in frontier AI technologies.
press release:
HUMAIN, a PIF company providing full-stack artificial intelligence capabilities globally, today announced a $3 billion strategic investment in xAI as part of the company’s Series E funding round. This transaction represents a significant end-to-end capital deployment for HUMAIN and reflects the continued momentum of our long-term investment strategy focused on category-defining technology platforms.
This investment comes at a very attractive inflection point for xAI, ahead of its acquisition by SpaceX in early February. Combining xAI’s advanced artificial intelligence capabilities with SpaceX’s scale, infrastructure and mission-driven engineering creates a platform uniquely positioned for accelerated growth, deep technology integration and long-term value creation.
As a result of the Series E transaction, HUMAIN became a significant minority shareholder in xAI, and its holdings were subsequently converted into SpaceX stock. This transaction reflects xAI’s participation in the final funding round prior to the merger and creates a solid platform for exposure to HUMAIN’s long-term equity appreciation.
“This investment reflects HUMAIN’s belief in transformative AI and our ability to put meaningful capital behind exceptional opportunities where long-term vision, technological excellence and execution power come together.
HUMAIN’s participation in the Series E round strengthens its role as a large-scale, long-term strategic investor capable of supporting companies across multiple growth stages, offering full-stack AI capabilities across four core areas: next-generation data centers, high-performance infrastructure and cloud platforms, advanced AI models, and innovative AI solutions.
The investment builds on a major partnership announced at the US-Saudi Investment Forum in November 2025, under which HUMAIN and xAI committed to jointly develop over 500MW of next-generation AI data center and computing infrastructure and deploy xAI’s Grok model in Saudi Arabia. Together, these initiatives deepen our long-term collaboration and expand HUMAIN’s role from a strategic partner to xAI’s major global shareholder.
Looking to the future, HUMAIN’s strategy includes pursuing additional investments across artificial intelligence, frontier technologies, and critical infrastructure.
