Institutional ownership of SpaceX came into clearer view in second-quarter 13F filings after the company listed on Nasdaq on June 12, according to BlockBeats.
Data compiled by third-party 13F platform Giantsight showed that, as of June 30, about 1,697 reporting entities disclosed positions in SpaceX. The filings covered different sources of capital, including pre-listing investors, venture capital firms, asset managers, and pension funds.
Largest disclosed SpaceX positions in 13F filings
SEC filings showed that Alphabet, the parent company of Google, reported holding 551 million SpaceX shares valued at $94.18 billion, making it the largest disclosed 13F position so far.
Other major filings included Valor Management with 503 million shares valued at $86.01 billion, FMR LLC with 303 million shares valued at $51.66 billion, Gigafund Management with 172 million shares valued at $29.36 billion, Saudi Arabia’s Public Investment Fund with 154 million shares valued at $26.34 billion, and BAMCO under Baron with 146 million shares valued at $24.91 billion.
Additional notable filers included Nvidia with 123 million shares valued at $20.98 billion, Baillie Gifford with 51.4 million shares valued at $8.78 billion, BlackRock with 51.04 million common shares valued at $8.72 billion, Ontario Teachers’ Pension Plan with 50.68 million shares valued at $8.66 billion, and Harvard University’s endowment fund with 12.935 million shares valued at $2.21 billion.
Where the holdings came from
By source of holdings, Alphabet and Gigafund were pre-listing investors in SpaceX. Nvidia’s SpaceX position came from its earlier investment in xAI. FMR, BAMCO, BlackRock, and Baillie Gifford mainly represented asset management capital.
The report said the appearance of these positions in 13F filings for the first time does not mean the institutions necessarily bought SpaceX shares in the secondary market after the listing. All values cited were quarter-end reported values as of June 30.
What 13F filings show and what they do not
SpaceX closed at $170.86 on June 30. As of Aug. 14, the stock closed at $140, down about 18.1% from the quarter end. If share counts were unchanged, the current market value of those common stock positions would have declined accordingly.
Form 13F mainly reflects long positions in reportable securities at quarter end, along with some option holdings. It does not disclose stock short positions, written options, the timing of purchases, transaction costs, or trading activity after the end of the quarter.
