HUMAIN, the Saudi Arabia-based artificial intelligence company backed by the Public Investment Fund, has invested $3 billion in xAI’s Series E funding round prior to the company’s acquisition by SpaceX in early February 2026.
The investment positioned HUMAIN as a significant minority shareholder in xAI. Following the merger, its equity stake was converted into shares in SpaceX, giving the Saudi-backed firm exposure to the broader aerospace and advanced technology ecosystem.
The transaction coincides with HUMAIN’s existing partnership with xAI, including a joint initiative to develop more than 500 megawatts of AI-focused data center infrastructure in Saudi Arabia. The planned infrastructure is expected to support large-scale model training, inference workloads, and advanced AI deployment across sectors.
HUMAIN’s investment reflects its broader strategy of backing frontier AI technologies and building sovereign digital infrastructure. By combining capital deployment with domestic data center expansion, the company is positioning itself as both a strategic investor and an infrastructure enabler in the global AI value chain.
The merger with SpaceX is expected to accelerate xAI’s technological integration and growth trajectory, potentially expanding its access to capital, compute capacity, and advanced engineering resources.
