Harvard Management Company reduced its Bitcoin ETF holdings by 21% in the fourth quarter while building a significant position in an Ethereum ETF, according to a recent SEC filing.
The Ivy League endowment disclosed that it held 5.35 million shares of BlackRock’s iShares Bitcoin Trust (IBIT) as of Dec. 31. The position carried a market value of $265.8 million. In the prior quarter, Harvard reported 6.81 million shares valued at $442.8 million. The reduction amounts to roughly 1.48 million shares.
Despite the cut, Bitcoin remains Harvard’s largest publicly disclosed equity holding. The endowment’s IBIT stake still exceeds its reported positions in major tech companies such as Alphabet, Microsoft, and Amazon.
At the same time, Harvard opened a new $86.8 million position in BlackRock’s iShares Ethereum Trust (ETHA). The filing shows that the fund purchased 3.87 million shares during the quarter. This marks Harvard’s first publicly disclosed exposure to an Ether-focused ETF.
Market Volatility Shapes Strategy
Harvard made these adjustments during a volatile period for digital assets. Bitcoin peaked near $126,000 in October 2025 before falling to $88,429 by year-end. Ether also faced pressure, declining roughly 28% over the same quarter.
Currently, Bitcoin trades near $68,600 while Ether hovers around $1,900. The shift suggests Harvard may be diversifying within crypto rather than exiting the asset class.
Institutional appetite for crypto ETFs continues to evolve. Asset managers such as BlackRock have expanded digital asset offerings, drawing capital from pensions, endowments, and hedge funds. Harvard’s move signals continued institutional engagement, even amid price swings.
Academic Scrutiny and Risk Debate
Harvard’s crypto allocation has drawn criticism from academic observers. According to reporting by The Harvard Crimson, some finance professors questioned the long-term value of digital assets.
Andrew F. Siegel, emeritus professor at the University of Washington, described Bitcoin as risky and noted that it had fallen 22.8% year-to-date. He argued that Bitcoin lacks intrinsic value, increasing uncertainty for long-term investors.
Avanidhar Subrahmanyam, a finance professor at UCLA, expressed similar concerns. He suggested that adding Ether amplifies valuation risks because cryptocurrency remains an unproven asset class with unclear pricing frameworks.
Still, Harvard appears to maintain conviction in crypto exposure. The endowment holds a combined $352.6 million across Bitcoin and Ethereum ETFs. That scale indicates strategic allocation rather than speculative positioning.
Institutional Crypto Strategy Evolves
Harvard’s decision reflects a broader trend among institutional investors. Rather than holding crypto directly, many institutions prefer regulated ETF structures. ETFs offer liquidity, custodial oversight, and compliance clarity under U.S. securities law.
By trimming Bitcoin while adding Ether, Harvard may seek to balance risk across the two largest digital assets. Bitcoin often acts as a macro hedge narrative asset, while Ethereum represents exposure to decentralized finance and blockchain infrastructure.
The portfolio shift underscores a nuanced approach: reduce concentration risk while maintaining substantial exposure to digital assets.
For now, Bitcoin remains the endowment’s dominant crypto position. However, the addition of Ether suggests Harvard sees long-term potential in the broader blockchain ecosystem beyond a single asset.
