Humain, an artificial intelligence company supported by Saudi interests, has injected $3 billion into Elon Musk’s AI startup xAI, the company said in a statement released Wednesday. The funding makes Humain a "significant minority shareholder" in xAI and arrived shortly before xAI was acquired by Musk’s space exploration company, SpaceX.
As part of the acquisition transaction, Humain’s ownership stake in xAI will be converted into shares of SpaceX, shifting the form of the investment from an AI startup holding to equity in the space company.
The move reinforces a growing commercial relationship between Musk and Humain, which was launched last year with an expressed aim of helping transform Saudi Arabia into a global AI center. In connection with the investment and broader cooperation, the two sides plan to jointly develop a 500 megawatt data center on Saudi soil.
Humain’s chief executive, Tareq Amin, framed the $3 billion commitment as evidence of the company’s "conviction in transformational AI" and of its capacity to deploy capital where "long-term vision, technical excellence, and execution converge." The firm said the funding formed part of xAI’s Series E financing round and occurred at what it described as a "highly compelling inflection point" prior to xAI’s acquisition by SpaceX in early February.
The investment follows a prior agreement announced in November 2025 during the U.S.-Saudi Investment Forum. At that time, the parties committed to collaborating on next-generation AI infrastructure and to deploying xAI’s Grok models within Saudi Arabia.
Humain is identified as a PIF company and presents itself as a full-stack AI operator, spanning data centers and infrastructure through to advanced AI models and AI solutions tailored for both public- and private-sector organizations.
While the announcement confirms the size and timing of the financial commitment and the conversion of holdings into SpaceX shares, further operational and financial details about the stake, the timetable for conversion, and the development path for the proposed data center were not disclosed in the statement.
