Summary
Harvard Management Company, the investment subsidiary managing Harvard University's endowment, executed a significant rebalancing of its cryptocurrency ETF portfolio in the fourth quarter of 2025. According to the university's 13F filing released in May 2026, Harvard reduced its position in BlackRock's iShares Bitcoin Trust by 21%, trimming holdings from approximately 6.85 million shares to 5.35 million shares. At the December 31, 2025 closing price of $49.65 per share, this position was valued at $265.80 million.
Concurrently, Harvard deployed capital into Ethereum for the first time, establishing a $86.82 million position in the iShares Ethereum Trust. The new position comprised 3.87 million shares, acquired at $22.43 per share on the same valuation date. This dual-action—reducing Bitcoin exposure while entering Ethereum—reflects a deliberate portfolio rotation rather than a wholesale exit from digital assets.
Despite the 21% reduction, Harvard's Bitcoin ETF holdings remained the largest single position in its investment portfolio, representing 12.78% of total assets. This data point underscores the university's maintained strategic commitment to Bitcoin exposure while managing risk through tactical rebalancing. Market analysts attributed the Bitcoin trim to heightened volatility and liquidity management considerations, particularly given the broader cryptocurrency market pressure in 2025, when Bitcoin ETFs declined 11.20% and Ethereum ETFs fell 17.90%.
The portfolio adjustment generated commentary from prominent figures in the cryptocurrency industry. Binance founder Changpeng Zhao noted the rotation publicly, speculating whether Harvard would next expand into alternative cryptocurrencies. The endowment's moves underscore how large institutional investors are managing digital asset allocations during periods of market uncertainty while maintaining exposure to the broader asset class.
