Harvard University's endowment significantly reduced its cryptocurrency exposure during Q1 2026, cutting its position in BlackRock's spot Bitcoin ETF by approximately 43% and fully exiting its Ethereum fund. According to regulatory filings, Harvard held 3,044,612 shares of the iShares Bitcoin Trust (IBIT) worth about $117 million as of March 31, representing a substantial reduction from the previous quarter. The endowment had previously scaled its Bitcoin position to approximately $443 million by Q3 2025, having initially purchased roughly 1.9 million shares for about $117 million in mid-2025. The latest 13F filings show Harvard trimmed 21% in Q4 before the deeper 43% cut in Q1 2026, marking a sharp pullback from the position's peak.
In contrast to Harvard's retreat, Abu Dhabi's Mubadala Investment Company significantly increased its Bitcoin exposure, lifting its IBIT stake by 16% to approximately $566 million. As reported in the latest 13F filings, Mubadala's holdings increased from 12,702,323 shares at the end of 2025 to 14,721,917 shares worth about $566 million. The Abu Dhabi fund has maintained a consistent accumulation strategy, adding to its Bitcoin ETF position every quarter since Q4 2024, demonstrating institutional conviction in the cryptocurrency space.
Harvard's decision to fully sell its $86.8 million Ethereum ETF position came after ETH fell sharply through early 2026, contributing to its short-lived run inside the endowment. The endowment had only added that stake one quarter earlier, highlighting the volatile nature of cryptocurrency markets. IBIT is no longer Harvard's largest disclosed public-equity holding, with TSMC, Alphabet, Microsoft, and SPDR Gold Trust now ranking ahead of it in the latest filings. The shift suggests rebalancing toward traditional assets rather than a full crypto withdrawal.
The contrasting moves by Harvard and Mubadala reflect a broader institutional split in cryptocurrency investments. According to the same wave of filings, Jane Street cut its IBIT shares by 71% and slashed Fidelity's FBTC by 60% in Q1, while JPMorgan increased its IBIT stake by 174% over the quarter. Emory University fully exited its small IBIT position, consolidating Bitcoin exposure into the Grayscale Bitcoin Mini Trust. This institutional divergence suggests that while some endowments and trading firms are taking profits or rotating exposure, sovereign wealth funds and major banks continue accumulating cryptocurrency exposure.
