Harvard University’s investment arm disclosed a $2.2 billion stake in SpaceX in a regulatory filing on Friday, making the rocket company the largest single U.S. equity holding in its $4.3 billion public stock portfolio and underscoring the windfall university endowments have reaped from SpaceX’s record-setting June initial public offering.
Harvard Management Company’s 13F filing, which covers U.S.-listed securities held as of June 30, revealed the position roughly six weeks after SpaceX debuted on the public markets at $135 per share. The stock closed at $140 on Friday, down 0.9% on the day, giving the company a market valuation above $1.8 trillion.
Early venture bets pay off for endowments
The Harvard stake reflects gains from investments made years before SpaceX’s IPO, when the company was still a private venture capital darling. University endowments that gained exposure through venture funds — in some cases more than a decade ago — have seen those positions convert into publicly traded shares worth billions.
Harvard Management Company oversaw roughly $57 billion in total assets as of June 2025, the most recent publicly available figure. The SpaceX position represents a significant concentration within its U.S. equity portfolio, which totaled $4.3 billion.

Harvard is not alone in benefiting from SpaceX’s public market debut. The University of California’s investment office disclosed a position worth approximately $1 billion in a filing this week. The University of North Carolina and Washington University in St. Louis also reported holdings in the company.
IPO gains arrive amid endowment headwinds
The disclosure comes at a time when university finances face multiple pressures, including uncertainty over federal research funding, demographic shifts reducing the pool of college-age students, and weaker returns from private equity investments.
Despite those challenges, large endowments have delivered strong recent performance. Funds managing more than $500 million returned a median 18.9% before fees for the year ended in June, according to the Wilshire Trust Universe Comparison Service.
SpaceX’s public debut was the largest in history, and its shares have fluctuated since listing. The company’s valuation of more than $1.8 trillion places it among the most valuable publicly traded companies globally.
Investment managers overseeing more than $100 million in U.S. equities are generally required to file Form 13F within 45 days after the end of each quarter, providing a snapshot of holdings in securities traded on U.S. exchanges. Friday’s filing reflects positions held as of June 30, 2026.
Neither Harvard Management Company nor SpaceX immediately responded to requests for comment on the filing.
SpaceX’s move to the public markets has drawn attention from major investors, including Ark Invest’s Cathie Wood, who has described the company as potentially the most important in global history. The company continues to expand its operations, including plans for a massive AI chip manufacturing facility in Texas.
