Saudi Arabian AI firm Humain has committed a substantial $3 billion investment to Elon Musk’s AI startup, xAI. Following a merger between xAI and SpaceX, this investment was converted into a significant minority equity stake in the aerospace giant. The partnership is designed to integrate advanced artificial intelligence with space-based infrastructure, marking a new frontier for technological collaboration. Key objectives include the development of extraterrestrial solar-powered data centers to support high-scale computing needs. This move aligns with Saudi Arabia’s strategic vision to become a global leader in frontier technologies and space exploration. The massive capital injection further validates the high valuations of Musk’s private ventures and strengthens sovereign-linked support for his ecosystem.
