Harvard Management Co. disclosed a $2.2 billion stake in Space Exploration Technologies Corp. (SPCX  ), an early investment in Elon Musk's rocket company whose value became public for the first time following SpaceX's blockbuster Nasdaq debut in June.

A Bigger Bet Than Amazon or Nvidia

The university held 12.94 million shares of SpaceX Class A common stock as of June 30, according to a 13F filing disclosed on Friday.

The stake makes SpaceX Harvard's largest disclosed public equity holding, well ahead of its next-largest positions in Amazon.com, Inc. (AMZN  ), Taiwan Semiconductor Manufacturing Co Ltd. (TSM  ), Cerebras Systems Inc (CBRS  ) and Nvidia Corp. (NVDA  ).

The SpaceX stake accounts for more than half of Harvard's $4.3 billion in total U.S. equities disclosed in the filing.

At Friday's closing price, Harvard's stake would be worth approximately $1.81 billion.

The University of California's investment arm also disclosed a stake in SpaceX, worth roughly $1 billion.

SpaceX Stock's Volatile Run

The company went public on the Nasdaq on June 12 and hit an all-time high of around $225 days later, before falling as low as around $104 in early August, a decline of more than 50% from its peak.

Shares have since rebounded after the company reported second-quarter revenue of $7.81 billion, up 92% year-over-year and ahead of the $6.93 billion analysts expected.

SpaceX's rebound since its post-IPO plunge has also boosted Elon Musk's net worth, which topped $858 billion last week, making him richer than Larry Page, Sergey Brin, and Jeff Bezos combined.

Other Big Investors In SpaceX

Nvidia disclosed a $21 billion stake in SpaceX as of the end of the second quarter, according to its own 13F filing.

Last week, Norway's $2.3 trillion sovereign wealth fund revealed a $1.22 billion stake in SpaceX, its first public disclosure of a position in the company.

Price Action: Shares of SpaceX closed 0.91% lower on Friday at $140 and gained 0.4% in extended trading.
