Harvard Cuts Bitcoin ETF Holdings as Mubadala Expands Crypto Exposure

Harvard University significantly reduced its exposure to BlackRock’s spot Bitcoin ETF during the first quarter of 2026, while Abu Dhabi sovereign wealth fund Mubadala increased its investment, according to newly released SEC 13F filings. The filings reveal a growing divide among major institutions over long-term confidence in crypto investment products.

Harvard Management Company reported holding 3,044,612 shares of BlackRock’s iShares Bitcoin Trust (IBIT) as of March 31, 2026, valued at approximately $117 million. The position represents a 43% decline from the previous quarter and continues a broader reduction trend that began after the fund reached a peak value of nearly $443 million in Q3 2025.

The university endowment initially entered the Bitcoin ETF market in mid-2025 with an investment worth around $117 million. After aggressively increasing its exposure, Harvard began trimming holdings in late 2025 before making deeper cuts in early 2026. The latest filing also showed the endowment completely exited its $86.8 million position in BlackRock’s spot Ethereum ETF (ETHA), only one quarter after establishing the stake.

The reduction in crypto ETF exposure comes as traditional assets such as TSMC, Microsoft, Alphabet, and SPDR Gold Trust have overtaken IBIT among Harvard’s largest public-equity holdings. Analysts believe the move may reflect portfolio rebalancing, liquidity management, or risk reduction rather than a total loss of confidence in digital assets.

In contrast, Mubadala increased its IBIT holdings by 16%, bringing its total stake to roughly $566 million. The Abu Dhabi fund has consistently expanded its Bitcoin ETF exposure since late 2024, highlighting continued institutional demand for spot Bitcoin products.

Other financial firms also adjusted their positions during Q1 2026. Jane Street sharply reduced its Bitcoin ETF holdings while increasing exposure to Ethereum ETFs. JPMorgan boosted its IBIT position by 174%, and Wells Fargo expanded its Ethereum ETF investments.

The latest institutional filings show that while some investors are taking profits or reducing risk, others continue to strengthen their positions in Bitcoin ETFs and Ethereum ETFs. Market watchers now await Q2 2026 filings to determine whether Harvard will continue reducing exposure or re-enter the crypto ETF market later this year.
