Harvard Management Company (HMC), which oversees Harvard University's endowment, disclosed a $2.2 billion stake in SpaceX in a regulatory filing Friday, August 14 — revealing that the university is now one of the largest institutional holders of Elon Musk's aerospace company and highlighting how handsomely an early bet on the firm has paid off.
By Far Harvard's Largest Public Holding
According to the 13F filing with the Securities and Exchange Commission, HMC held 12,935,100 shares of SpaceX worth $2.21 billion as of June 30, 2026. The position accounted for more than half of the roughly $4.3 billion in US equities disclosed in the filing — and was worth more than all of Harvard's other publicly reported holdings combined. Harvard's next-largest disclosed position was a roughly $350 million stake in Taiwan Semiconductor Manufacturing Company (TSMC), making the SpaceX holding more than six times larger than any other single position in the portfolio.
A Portfolio That More Than Doubled
HMC's publicly disclosed equity portfolio surged roughly 135% this quarter to $4.26 billion, its largest reported value since at least 2006. Harvard oversaw $57 billion in total endowment assets as of June 2025, the latest publicly available full figure — meaning the SpaceX stake alone now represents a meaningful slice of the university's overall investment footprint, even though 13F filings only capture a portion of an institution's total holdings (excluding private equity, real estate, and other non-public securities).
A Broader Bet on AI and Semiconductors
The SpaceX disclosure comes amid a broader shift in HMC's public equity strategy toward artificial intelligence and semiconductor companies. Last quarter, Harvard purchased 1.1 million shares in Generate Biomedicines, an AI-focused biotech company, valued at roughly $14 million at the time. This quarter, HMC opened a nearly $239 million position in Cerebras Systems, an AI chipmaker, making it Harvard's third-largest publicly disclosed holding behind SpaceX and TSMC. The fund also increased its existing holdings in Nvidia and TSMC, further deepening its exposure to the AI and chip sector.
Pulling Back From Crypto
At the same time Harvard was ramping up its tech and AI exposure, it moved in the opposite direction on digital assets — exiting its Ethereum holdings entirely last quarter and cutting its stake in Bitcoin, scaling back its cryptocurrency exposure considerably. HMC also trimmed its position in Booking Holdings, the parent company of Booking.com, as part of the broader portfolio rebalancing.
Harvard Isn't Alone in the SpaceX Rush
Harvard's disclosure follows a wave of major institutional investors revealing significant SpaceX stakes in recent days. Norway's sovereign wealth fund, the world's largest at roughly $2.3 trillion, disclosed a $1.2 billion SpaceX position of its own on August 12 — notable given that the same fund has twice voted against Musk's compensation packages at Tesla, citing concerns over shareholder dilution and "key person risk." SpaceX's stock has traded actively since going public earlier this year, closing at levels above its $135 IPO price as institutional demand has grown.
The Bigger Picture
Harvard's outsized SpaceX position underscores just how much value has accrued to early institutional investors in Musk's rocket company, even as questions persist across markets about concentration risk in AI- and space-adjacent tech names. With HMC's public equity portfolio now heavily weighted toward a handful of high-conviction bets — SpaceX, TSMC, Cerebras, and Nvidia chief among them — the endowment's strategy increasingly mirrors the broader institutional rush into AI infrastructure and semiconductor exposure seen across Wall Street this year. For Harvard's full 13F filing, see the SEC's EDGAR database.
With SpaceX now anchoring more than half of Harvard's disclosed public equity holdings, the university's endowment has effectively made one of the most concentrated single-stock bets of any major institutional investor currently reporting to the SEC.
