HUMAIN, an artificial intelligence company owned by Saudi Arabia’s Public Investment Fund (PIF), has invested US$ 3 billion in xAI’s Series E funding round shortly before the AI company was acquired by SpaceX. The deal builds on a partnership announced in November 2025 in the U.S.-Saudi Investment Forum. Under that agreement, HUMAIN and xAI committed to jointly develop a 500 MW AI data center and compute infrastructure in Saudi Arabia and to deploy xAI’s Grok models in the country.
According to a press release, the transaction made HUMAIN a significant minority shareholder in xAI. Following the acquisition in early February, its holdings were converted into SpaceX shares, giving HUMAIN equity exposure to the combined business after participating in xAI’s final standalone financing round.
Tareq Amin, CEO, HUMAIN, said, “This investment reflects HUMAIN’s conviction in transformational AI and 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.”
The investment comes as xAI moves into closer integration with SpaceX’s infrastructure and engineering operations. The merger ranks among the largest technology deals on record and combines xAI’s artificial intelligence models with SpaceX’s large-scale compute capacity and operational footprint.
This investment reflects HUMAIN‘s strategy of backing large-scale AI platforms and infrastructure assets. The company provides data center development, cloud and high-performance computing infrastructure, advanced AI models and enterprise AI applications. It said it intends to pursue additional investments in artificial intelligence, frontier technologies and related infrastructure.
