What was disclosed

Nvidia has disclosed in an SEC filing that it owned nearly 123 million shares of SpaceX at the end of June, a position valued at almost $21 billion at that time. The filing brings new visibility to the chipmaker’s financial exposure to one of Elon Musk’s companies and to the increasingly interlinked relationships around AI infrastructure.

The position has since declined in value. SpaceX shares have fallen sharply since the company’s June initial public offering, putting Nvidia’s stake at about $17 billion now. Even after that drop, the holding remains one of the most striking examples of a major AI supplier owning a large stake in a major customer ecosystem.

How xAI fits into the story

The SpaceX holding is tied to Nvidia’s earlier investment in xAI, which was completed in January. Shortly afterward, Musk combined the AI lab with SpaceX. As a result, Nvidia’s xAI investment turned into a substantial SpaceX equity position and, based on the disclosed values, a major paper gain.

Key figures in the filing and report include:

• SpaceX shares held by Nvidia: nearly 123 million;
• Value at the end of June: nearly $21 billion;
• Estimated value now: about $17 billion;
• Nvidia market value cited: $5.5 trillion;
• Relevant transaction path: Nvidia invested in xAI in January, before xAI was combined with SpaceX.

For readers less familiar with financial filings, an SEC disclosure is a regulatory document that can reveal significant holdings or corporate information. A stake’s reported market value can move with the share price and is not the same as realized cash profit.

Exclusive data center relationship

The financial disclosure follows Musk’s comments during SpaceX’s first public earnings call last week. He said SpaceX had entered an exclusive arrangement with Nvidia to equip its data centers. Musk said the company had decided to build exclusively on Nvidia because it viewed the Vera Rubin architecture as the best architecture and the best AI computer, and he emphasized close cooperation between the companies.

In simple terms, an AI data center is a facility packed with specialized chips, servers, networking and cooling systems used to train or run AI models. Vera Rubin is the name of Nvidia’s AI computing architecture referenced by Musk. The report did not provide details such as the size of SpaceX’s data centers, the value of equipment orders or a deployment schedule.

That makes Nvidia both a technology supplier and a financial stakeholder in the broader Musk AI-and-space structure. The overlap is commercially powerful, but it also makes the relationship more complicated than a standard vendor-customer deal.

Why it matters for the AI market

The disclosure highlights CEO Jensen Huang’s broader strategy of using Nvidia’s financial strength to build deep links across the AI industry, including with some of the company’s largest customers. These relationships can become circular: Nvidia invests in AI-related companies, and those companies may rely on Nvidia hardware to build the computing capacity they need.

That model can accelerate ecosystem growth and reinforce Nvidia’s position in high-end AI computing. It can also draw attention to transparency, customer independence and the line between organic demand and investment-backed demand. As AI infrastructure spending expands, filings like this one will become important clues for understanding how capital, chips and strategic partnerships are shaping the next phase of the industry.
