Harvard University’s endowment kept its stake in BlackRock’s spot Bitcoin ETF unchanged in the second quarter, while SpaceX remained its largest disclosed holding, according to the latest 13F filing cited by BlockBeats on Aug. 16.
As of June 30, Harvard held 3.0446 million shares of the iShares Bitcoin Trust (IBIT), worth about $101.4 million. The share count was unchanged from the end of the first quarter.
That stopped a two-quarter run of reductions in the position. The filing shows Harvard cut its IBIT holdings by 21% in the fourth quarter of 2025 and by another 43% in the first quarter of 2026. Based on the filing, IBIT accounted for about 2.4% of Harvard’s disclosed $4.26 billion U.S. equity portfolio.
Gold holdings remained larger
Harvard’s exposure to gold-related products was still bigger than its IBIT position at the end of the second quarter. Its holdings in iShares Gold Trust (IAU) and SPDR Gold Trust (GLD) had a combined value of about $171.2 million.
The filing also shows that Harvard had previously fully exited BlackRock’s spot Ether ETF position, which had been valued at $86.8 million. It did not add any new Ethereum-related position in the second quarter.
SpaceX made up the largest single holding
Harvard’s largest disclosed stock position was SpaceX, with 12,935,100 shares valued at $2.21 billion. It was the biggest single stock holding in the filing.
The endowment’s disclosed U.S. stock assets totaled about $4.3 billion, which means the SpaceX position represented roughly 52% of that portfolio.
Other institutions showed mixed IBIT changes
Among other institutions, Abu Dhabi sovereign wealth fund Mubadala and the Abu Dhabi Investment Council both left their IBIT positions unchanged at 14.7219 million shares and 8.2187 million shares, respectively. Their combined holdings were worth about $764 million.
JPMorgan increased its IBIT position from about 8.3 million shares to 10.4 million shares. Morgan Stanley reduced its position from 17.3 million shares to about 16.5 million shares, a decline of 4.5%.
