Saudi Arabia’s HUMAIN has taken a significant minority stake in xAI through a $3 billion Series E investment, deepening the Kingdom’s exposure to global artificial intelligence infrastructure and innovation.
Saudi Arabia’s AI focused company HUMAIN has invested $3 billion in the Series E funding round of Elon Musk’s artificial intelligence venture xAI, according to multiple international reports. The investment grants HUMAIN a significant minority stake in xAI and strengthens Saudi Arabia’s participation in global AI infrastructure and frontier model development.
The transaction was reported by Financial Times and regional outlets including Wamda, which confirmed HUMAIN’s participation in the funding round. The investment was made shortly before xAI’s acquisition by SpaceX, a move that consolidated Musk’s AI and aerospace assets under a broader corporate structure.
HUMAIN’s stake was part of a larger Series E raise that reportedly totalled approximately $20 billion. The round included participation from global investors and represents one of the largest private AI financings to date.
HUMAIN, established with backing from Saudi Arabia’s sovereign wealth ecosystem, is focused on developing advanced artificial intelligence capabilities, including large-scale compute infrastructure and AI model deployment. The company previously announced plans to collaborate with xAI on building high capacity AI data centres within Saudi Arabia. Reporting from PR Newswire indicated that the partnership includes plans for more than 500 megawatts of AI data centre capacity in the Kingdom.
The investment aligns with Saudi Arabia’s broader economic diversification strategy under Vision 2030, which prioritises advanced technologies including artificial intelligence, cloud infrastructure and data centre development. The Kingdom has increasingly positioned itself as a capital provider and infrastructure host for next generation AI platforms.
Globally, AI companies such as OpenAI and Anthropic have attracted multibillion-dollar funding rounds in recent years, underscoring sustained institutional capital flows into foundational AI technologies. HUMAIN’s $3 billion commitment places it among the largest sovereign-backed investors participating directly in frontier AI financing rounds.
No additional financial details, including HUMAIN’s exact ownership stake or xAI’s post money valuation at the time of the Series E close, were disclosed in public filings or company statements.
