Harvard Management Company kept its 3,044,612 shares of BlackRock's iShares Bitcoin Trust unchanged in the second quarter, ending two straight quarters of reductions in its publicly disclosed Bitcoin exposure. The stake was worth about $101.4 million at June 30, down roughly $15.6 million from March because of IBIT's lower quarter-end price rather than additional selling. Harvard's latest Form 13F showed no BlackRock Ethereum ETF position, indicating it did not rebuild that exposure, and its disclosed gold ETF holdings of about $171.2 million remained larger than its Bitcoin ETF stake. Abu Dhabi investors Mubadala Investment Company and Abu Dhabi Investment Council also kept a combined 22.94 million IBIT shares worth about $763.7 million. Elsewhere, Dartmouth kept its Bitcoin, Ethereum and Solana ETF positions unchanged, JPMorgan increased reported IBIT holdings, Morgan Stanley reduced its stake and Tudor Investment Corporation added shares.
