Harvard University's endowment kept its BlackRock iShares Bitcoin Trust holding unchanged in the second quarter, ending a two-quarter stretch of reductions and leaving the position at 3,044,612 shares worth about $101.4 million as of June 30. The stake had been cut by 21% in the fourth quarter and by a further 43% in the first quarter, but the latest 13F filing shows no additional trimming or rebuilding in Q2. IBIT accounted for about 2.4% of Harvard's disclosed roughly $4.26 billion U.S. equity portfolio, while the endowment's gold-related products remained larger at a combined roughly $171.2 million in iShares Gold Trust and SPDR Gold Trust holdings. Harvard had previously exited a BlackRock spot Ethereum ETF position worth $86.8 million and did not add any Ethereum-related exposure in the second quarter. The filing also showed SpaceX as Harvard's largest disclosed holding at 12,935,100 shares worth $2.21 billion, or about 52% of its disclosed U.S. stock assets. Elsewhere, Abu Dhabi sovereign wealth fund Mubadala and Abu Dhabi Investment Council kept their IBIT stakes unchanged, while JPMorgan increased its holding and Morgan Stanley reduced its position.
