Nvidia discloses $21B SpaceX stake, Harvard reveals $2.2B holding

Two major institutional filings landed on the same day this quarterly disclosure season, both putting SpaceX at the top of their reported holdings — a reminder of how much appetite there is for Musk's rocket and satellite company across both AI-industry and endowment money.

Nvidia's $21 billion stake (122.8 million Class A shares) traces back to its $10 billion participation in xAI's $20 billion funding round in January, which converted into SpaceX equity after SpaceX completed its acquisition of xAI in February. Per FactSet, Nvidia is now SpaceX's sixth-largest investor, and the position is Nvidia's second-biggest holding behind its roughly $22 billion Intel stake. The value has since slipped to about $17.2 billion, though, as SpaceX's stock closed at $140 on Friday, down from $170.86 at the end of June.

Harvard Management Company's disclosure was even more striking: its 12,935,100 SpaceX shares, worth $2.21 billion as of June 30, made up more than half of the roughly $4.3 billion in total securities HMC reported to the SEC — more than six times its next-largest holding, a roughly $350 million stake in TSMC.

Neither filing moves Tesla's fundamentals directly, but both add to the backdrop of Musk's expanding personal wealth and influence through SpaceX. The disclosures also come as SpaceX has said it will use Nvidia's AI chips exclusively across its data centers and frontier AI models, tying the two companies' businesses closer together.
