Harvard’s $2.2 Billion Stake Makes SpaceX Its Biggest Reported Holding

Overview

• The quarter‑end 13F filings that reported holdings as of June 30 show Harvard Management Co. holds more than $2.2 billion of SpaceX stock, about 12.94 million shares, and the position is the largest U.S. equity holding disclosed on its filing.
• Alphabet is the largest institutional shareholder in the filings with roughly 551.2 million SpaceX shares, a stake valued at about $94.2 billion at the end of the quarter.
• Despite the new visible stakes, founder Elon Musk retained decisive control under the company’s share and vote structure, holding about 48.4% of the economic interest and more than 82% of voting power in the filings.
• The IPO converted long‑held private positions into large public ones that are heavily concentrated: the top institutional holders account for roughly three quarters of reported public shares and include university endowments, banks, sovereign funds, asset managers and family offices.
• The 13F data are a snapshot that do not show full endowment assets or trades after June 30, so markets will watch upcoming lockup expirations and later quarterly filings for whether these large holders keep their stakes, take profits, or add to positions and how that affects liquidity and volatility.
