In Harvard’s publicly disclosed U.S. stock portfolio, SpaceX alone accounts for more than half.

The latest 13F shows that Harvard Management Company held approximately 12.94 million shares of SpaceX as of the end of June, worth about $2.21 billion at the time; its entire filing disclosed only about $4.26 billion in U.S. equity assets. In other words, SpaceX alone was larger than all its other disclosed holdings combined.
But this is the easiest point to misread: it does not mean Harvard suddenly poured $2.2 billion into SpaceX recently. SpaceX did not go public until June, and these shares likely include long-term positions acquired earlier through private placements and venture capital funds. The 13F only tells us what it held at the end of June—not when it bought them or what they cost.
That is precisely what makes this interesting. Ordinary investors only began debating whether $140 was expensive after SpaceX went public, while many institutions were betting on commercial spaceflight a decade ago. Alphabet’s roughly $900 million investment in SpaceX had even reached a book value of about $94.2 billion by the end of June.
SpaceX most recently closed near $140 on Friday, down about 18% from $170.86 at the end of June. If Harvard’s position has not changed, the quarter-end book value of $2.21 billion would now be worth only about $1.81 billion.
So this is not a simple story about “Harvard being bullish on SpaceX,” but rather a question of investment time horizons: the most spectacular returns are often not achieved by chasing an asset after it goes public, but by securing a position early, when no one else can yet see clearly.
Of course, buying early does not mean an asset can never become expensive. SpaceX is still a trillion-dollar company, and its AI, Starlink, and rocket businesses all require massive capital expenditures. The real question for the next stage is: at such a high valuation, when will profits catch up?
The most important takeaway from Harvard’s $2.2 billion position is not that “even top universities chase hot stocks,” but that it serves as a reminder: the climax visible in public markets is often the result of early-stage capital having already spent many years getting there.$SPCX #SpaceX #股票交易分享挑战
