Humain invests $3B in Elon Musk’s xAI, becomes SpaceX shareholder

Humain, the Saudi state-backed artificial intelligence company, announced a $3 billion strategic investment in Elon Musk’s xAI as part of the startup’s Series E financing round, a move that converted into SpaceX equity after xAI was folded into SpaceX and made Humain a SpaceX shareholder. The deal, disclosed in a Humain news release and reported by Tech Startups on February 18, 2026, gives the company a significant minority stake in xAI and ties a Saudi investor directly into Musk’s aerospace and AI operations.

“HUMAIN, a PIF company delivering full-stack artificial intelligence capabilities globally, today announced a $3 billion strategic investment in xAI as part of the company’s Series E financing round,” Human said in a news release.

Context and deal details

The $3 billion injection follows a string of infrastructure and capital moves by Humain and other Saudi funds. Weeks earlier Humain secured a financing agreement of up to $1.2 billion from Saudi Arabia’s National Infrastructure Fund under non-binding terms to build up to 250 megawatts of data center capacity. That infrastructure focus aligns with a prior November announcement at the U.S.-Saudi Investment Forum, where Humain and xAI said they would jointly develop 500 megawatts of AI data center infrastructure.

• Investor: Humain (described in the release as a PIF company)
• Target: xAI (now folded into SpaceX)
• Investment amount: $3 billion
• Related financing: up to $1.2 billion from the National Infrastructure Fund for up to 250 MW of data center capacity
• Previous infrastructure pledge: joint plan for 500 MW announced in November at the U.S.-Saudi Investment Forum
• xAI Series E upsized haul: $20 billion disclosed in January

According to the report, xAI disclosed in January that it had raised $20 billion in an upsized Series E round as it expanded model development and infrastructure to compete with firms like OpenAI and Anthropic. A month later, Elon Musk consolidated xAI into SpaceX, converting xAI shares into SpaceX equity — a move that turned Humain’s stake into an ownership position within SpaceX.

Observers quoted in the Tech Startups piece framed the investment as more than a financial bet: it links Saudi Arabia’s capital and energy resources to compute-heavy AI ambitions. The company is also pursuing product development: in October Humain revealed plans for “Humain 1,” a voice-controlled operating system designed to let users interact with computers through conversation rather than traditional graphical interfaces.

Outlook

With xAI now part of SpaceX, Humain’s $3 billion investment gives Saudi Arabia exposure to an integrated technology portfolio spanning AI research, data infrastructure and aerospace capabilities. The stake places a Saudi-backed investor inside one of the world’s most capitalized and vertically integrated tech companies, while reinforcing ongoing commitments to build out megawatt-scale data center capacity. How Humain and related Saudi funds translate those ownership and infrastructure positions into operational collaboration with SpaceX and xAI — on compute, data center siting, or product development such as Humain 1 — will shape the next phase of this cross-border technology partnership.
