Harvard SpaceX stake revealed: $2.2 billion endowment holding

Harvard SpaceX stake disclosed in 13F filing

Harvard Management Company revealed a Harvard SpaceX stake valued at ↑ $2.2 billion in its latest 13F, making the university one of the largest private holders of Elon Musk’s rocket firm.

The filing shows the endowment owned $4.3 billion of U.S. equities, with SpaceX listed as the top single holding. Harvard’s total assets were $57 billion as of June 2025, according to public data.

Impact on university portfolios

SpaceX’s June IPO propelled returns for several college endowments that backed the company through venture‑capital channels over a decade ago. The University of California system reported a position near $1 billion, while UNC and Washington University in St. Louis disclosed smaller stakes.

“We do not comment on individual positions,” said Patrick McKiernan, spokesperson for Harvard Management.

At a market valuation exceeding $1.8 trillion, SpaceX’s share price has oscillated since debuting at $135, closing at $140 on Friday. The gains arrive as U.S. universities face tighter federal research budgets, shrinking applicant pools, and modest private‑equity returns. Endowments over $500 million posted a median pre‑fee return of ↑ 18.9% for the year ending June, per Wilshire Trust data.

Money managers handling more than $100 million in U.S. equities must submit a 13F within 45 days of quarter‑end, detailing holdings on U.S. exchanges. For broader context, see Reuters and Bloomberg.
