Harvard Management Co. (HMC) has revealed a substantial $2.2 billion stake in Elon Musk's Space Exploration Technologies Corp. (SpaceX) through its recent 13F filing. This disclosure highlights the university endowment's early and profitable investment in the private rocket company.
The $2.2 billion position makes SpaceX the largest single stock disclosed in HMC's $4.3 billion portfolio of U.S. equities. As of June 2025, Harvard oversaw a total endowment of $57 billion. The significant gains for Harvard, and other universities, are attributed to SpaceX's record-breaking initial public offering (IPO) in June 2026, which boosted returns for college endowments that invested in the company, sometimes more than a decade ago through venture capital firms.
Other educational institutions also benefited from SpaceX's public debut, with the University of California's investment arm disclosing a roughly $1 billion position, and the University of North Carolina and Washington University in St. Louis also holding investments. This investment success comes as university finances face pressures from various factors, including uncertainty over federal research funding, demographic shifts reducing college-age student pools, and historically weaker returns from private equity. Despite these challenges, endowment funds managing over $500 million reported a median return of 18.9% before fees in the year ending June 2026, according to the Wilshire Trust Universe Comparison Service.
SpaceX currently boasts a valuation exceeding $1.8 trillion. The Harvard stake could comprise both directly owned shares and distributions from private investment funds. On August 19, 2026, SpaceX stock, trading under the ticker SPCX, was at $139.65, a -2.57% change, with an after-hours price of $137.32, down -1.66%. On August 15, 2026, SpaceX stock closed at $140, down 0.9% from its debut price of $135 per share.
