Institutional holdings in SpaceX came into clearer view for the first time through second-quarter 13F filings after the company listed on Nasdaq on June 12. Giantsight, a third-party 13F platform, counted about 1,697 reporting entities with disclosed SpaceX positions as of June 30, including pre-listing investors, venture capital firms, asset managers and pension funds. SEC filings showed Alphabet reported the largest disclosed 13F position with 551 million SpaceX shares valued at $94.18 billion. Other large holders included Valor Management with 503 million shares worth $86.01 billion, FMR LLC with 303 million shares worth $51.66 billion, Gigafund Management with 172 million shares worth $29.36 billion, Saudi Arabia's Public Investment Fund with 154 million shares worth $26.34 billion, and BAMCO under Baron with 146 million shares worth $24.91 billion. Nvidia disclosed 123 million shares worth $20.98 billion, while Baillie Gifford, BlackRock, Ontario Teachers' Pension Plan and Harvard University's endowment also appeared among major filers. The filings reflect end-of-quarter reportable long positions, not necessarily secondary-market purchases after the listing. They also do not show stock shorts, written options, purchase timing, cost basis or trades after quarter-end. SpaceX closed at $170.86 on June 30 and at $140 on Aug. 14, down about 18.1% from the quarter end, implying a corresponding drop in the current value of those common-stock positions if share counts were unchanged.
