Key Takeaways
- • Nvidia disclosed a $21 billion stake in SpaceX comprising 122.8 million Class A shares as of Q2 2026, making SpaceX its second-largest holding after Intel ($22 billion).
- • Nvidia's SpaceX position originated from its $10 billion investment in xAI during a $20 billion funding round in January 2026, with SpaceX subsequently acquiring xAI in February for $1.25 trillion.
- • SpaceX's June 2026 IPO valued the company at approximately $1.75 trillion; Nvidia's stake has declined to approximately $17.2 billion as of the reporting date, with SpaceX stock trading at $140 versus $170.86 at quarter-end.
- • Nvidia ranks as the sixth-largest SpaceX investor, with Elon Musk holding the dominant position ($850 billion), followed by Alphabet ($78 billion); the investment reinforces the strategic AI infrastructure partnership between the two companies.
- • Musk confirmed on SpaceX's Q2 earnings call that the company will exclusively use Nvidia GPUs in its AI data centers, citing Nvidia's superior architecture for AI model training and inference.
Summary
Nvidia disclosed Friday that it holds a $21 billion stake in SpaceX consisting of 122.8 million Class A shares as of the end of the second quarter 2026. The stake represents Nvidia's second-largest equity position, surpassed only by its Intel investment valued at approximately $22 billion—a position that has appreciated substantially from Nvidia's $5 billion investment made less than a year prior. The SpaceX investment carries strategic significance beyond financial returns, embedding Nvidia deeper into the aerospace-AI infrastructure ecosystem at a critical inflection point for space-based data services.
Nvidia's SpaceX exposure materialized indirectly through its $10 billion investment in Elon Musk's artificial intelligence startup xAI, which participated in a $20 billion funding round in January 2026. SpaceX subsequently acquired xAI in February 2026 in a transaction valued at $1.25 trillion, effectively converting Nvidia's xAI investment into direct SpaceX equity. This structure reflects the consolidation of Musk's technology holdings and suggests coordinated strategic integration across AI infrastructure, space operations, and satellite capabilities.
SpaceX completed its initial public offering in June 2026 at an implied valuation of $1.75 trillion. Nvidia's position has experienced mark-to-market volatility; shares trading at $170.86 at quarter-end have since declined to $140, reducing the current value of Nvidia's holding to approximately $17.2 billion. Despite the paper loss, Nvidia maintains the sixth-largest investor position in SpaceX. Elon Musk retains dominant control with an estimated $850 billion stake, while Alphabet holds the second-largest external position at approximately $78 billion.
The partnership reflects deepening commercial integration between the two companies' core technologies. During SpaceX's second-quarter earnings call, Musk confirmed that SpaceX will exclusively deploy Nvidia graphics processing units across its AI data center infrastructure, citing Nvidia's architectural superiority for AI model training and inference workloads. This commitment signals confidence in sustained demand for Nvidia's accelerated computing platforms and establishes a significant customer anchor for Nvidia's data center business within the emerging space-based computing sector.
