First-quarter 2026 13F filings with the U.S. Securities and Exchange Commission show Harvard’s endowment cut its stake in BlackRock’s iShares Bitcoin Trust by about 43%, leaving 3,044,612 shares valued at roughly $117 million, after already trimming the position by 21% in the fourth quarter of 2025. Harvard also fully exited its BlackRock Ether ETF position, eliminating exposure described in the source as about $86.8 million. The filing reflects a broader reduction in the endowment’s reported exposure to spot crypto exchange-traded funds. The source also notes that Abu Dhabi sovereign wealth fund Mubadala Investment Company moved in the opposite direction, increasing its IBIT holdings to 14,721,917 shares worth about $566 million, up from roughly 12.7 million shares at the end of 2025.
