Space Exploration Technologies Corp. (NASDAQ: SPCX) shares are trading above their IPO price after a fresh batch of regulatory disclosures revealed substantial equity positions held by Silicon Valley giants and major institutional investors. The filings highlight a broadening investor base, ranging from university endowments to hedge funds, with Alphabet Inc. (NASDAQ: GOOGL, NASDAQ: GOOG) disclosing the largest position among the tech giants.

Major Tech Stakeholders

Alphabet reported holding approximately 551 million SpaceX shares valued at about $94 billion in its 13F-HR filed on August 7. This stake, which traces back to a $900 million investment in 2015, now dwarfs the rest of Google’s disclosed public equity portfolio. The filing indicates that roughly $80 billion of this position remains under short-term lockup, with an additional $14.1 billion restricted through the third quarter of 2027.

Nvidia Corp. (NASDAQ: NVDA) reported holding about 122.76 million SpaceX shares valued near $21 billion in its filing dated August 14. This position reportedly stems from Nvidia’s earlier investment in xAI. Advanced Micro Devices (NASDAQ: AMD) also entered the SpaceX cap table, disclosing a $565.5 million stake in its 13F-HR filed on August 14.

Institutional and Hedge Fund Exposure

On the institutional side, Harvard Management Co. revealed a $2.2 billion SpaceX position, marking it as the firm’s single largest disclosed equity holding. Citadel Advisors also disclosed a new SpaceX position in its 13F-HR, alongside new stakes in Cerebras Systems (NASDAQ: CBRS) and Quantinuum. Citadel’s overall equity portfolio ballooned 41.5% to $875.1 billion during the period.

The most concentrated bet belongs to Atreides Management. The tech-focused hedge fund’s 13F-HR shows SpaceX making up roughly 42% of its portfolio, a position valued at $4.67 billion at quarter-end. Other notable holders include Saudi Arabia’s Public Investment Fund, which reported a 154.1-million-share stake worth roughly $26.3 billion, and Ontario Teachers’ Pension Plan.

A long tail of other reported holders includes Fidelity Investments with 302.6 million shares, Gigafund Management with 171.8 million shares, Baillie Gifford with 51.4 million shares, and BlackRock with about 51 million shares. According to Chaincatcher’s tally, approximately 1,697 reporting entities disclosed SpaceX positions.

Share Unlock Timeline

Separately from Google’s own lockup terms, SpaceX’s broader share-unlock timeline is rolling out gradually rather than in one release. Roughly 912 million shares held by other early backers and employees became tradable on August 6, with an additional 319 million shares due to unlock on August 20, Barron’s reported.

What the Numbers Show

The disparity between Alphabet’s initial investment and current valuation highlights the magnitude of SpaceX’s post-IPO market appreciation. Alphabet invested $900 million in 2015 for a stake now valued at roughly $94 billion. This represents a nominal return multiple of over 100x on the original capital deployed, although the bulk of the position remains illiquid due to lockup restrictions expiring in late 2027. Meanwhile, the high concentration at Atreides Management (42% of portfolio) signals a distinct risk profile compared to diversified institutional holders like Harvard or BlackRock.

Because 13F filings only capture positions as of quarter-end and are disclosed up to 45 days later, these snapshots reflect holdings as of June 30. They do not capture any buying or selling activity since then, meaning the current ownership picture may already differ given SpaceX’s price swings since its debut. As of publication Monday, SPCX stock was up 4.17% at $145.84.

Harvard Management Co. has disclosed a $2.2 billion stake in Space Exploration Technologies Corp. (NASDAQ: SPCX), marking the university’s largest public equity holding to date. The filing reveals that Harvard held 12.94 million shares of SpaceX Class A common stock as of June 30, valuing the position at approximately $1.81 billion at Friday’s closing price.

The investment represents a significant concentration within Harvard’s portfolio. The SpaceX stake accounts for more than half of the university’s $4.3 billion in total US equities disclosed in the filing. This positions SpaceX well ahead of Harvard’s next-largest holdings, which include Amazon.com Inc., Taiwan Semiconductor Manufacturing Co Ltd., Cerebras Systems Inc., and Nvidia Corp.

What the Numbers Show

The disparity between the disclosed stake value and current market valuation highlights the volatility following SpaceX’s public debut. While the 13F filing values the holding at $2.2 billion, the market value at Friday’s close was $1.81 billion. This divergence underscores the price action since the company went public on June 12, hitting an all-time high of around $225 before falling to roughly $104 in early August, a decline of more than 50% from its peak.

Institutional Interest and Market Context

SpaceX shares have rebounded following the company’s second-quarter revenue report of $7.81 billion, up 92% year-over-year and ahead of analyst expectations of $6.93 billion. This performance contributed to Elon Musk’s net worth topping $858 billion last week.

Other major institutional investors have also disclosed significant positions:

• Nvidia Corp. disclosed a $21 billion stake as of the end of the second quarter.
• Alphabet Inc. revealed a $94.1 billion stake, with about $80 billion under short-term sale restrictions and $14.1 billion locked up through the third quarter of 2027.
• Norway’s sovereign wealth fund disclosed a $1.22 billion stake, its first public position in the company.
• The University of California’s investment arm also holds a stake worth roughly $1 billion.

SpaceX shares closed 0.91% lower on Friday at $140, gaining 0.4% in extended trading.
