A reduction in bitcoin, a first entry into Ether
As bitcoin capitulated to $60,000, Harvard Management Company made a significant adjustment to its crypto ETF positions in the fourth quarter of 2025 according to a filing with the US Securities and Exchange Commission.
The elements declared are as follows:
- A reduction of the position in the BlackRock iShares Bitcoin Trust (IBIT):
5.35 million shares held as of December 31, 2025, valued at approximately $265.8 million, compared to 6.81 million shares representing $442.9 million in the previous quarter;
- Opening a new position in the iShares Ethereum Trust:
3.87 million shares acquired, for an estimated value of $86.8 million at the end of the fourth quarter of 2025.
This data appear in form 13F filed with the American regulator, which lists the positions held by large institutional managers. This is Harvard's first reported exposure to a spot Ether ETF, marking a formal shift in the composition of its allocation to cryptos via listed and regulated products.
Market volatility and the evolution of the institutional approach
This repositioning comes after a period of strong instability on the crypto market. In the second half of 2025, the price of bitcoin fell from over $120,000 to under $90,000, while Ether fell from over $4,000 to under $3,000 before the end of the year. This correction sequence constitutes the market framework within which the endowment carried out its arbitrages.
Beyond price fluctuations, these movements are part of a global dynamic of institutional adoption of cryptos via spot ETFs. These vehicles allow traditional investors to access cryptos without direct custody, while remaining within a regulated framework. The choice ofHarvard illustrates this trend: maintaining exposure to bitcoin while integrating Ether into the allocation, via structured products offered by BlackRock.
Harvard is adjusting its digital exposure as the crypto market tumbles into extreme fear. Reduction of bitcoin, opening to Ether: the maneuver illustrates a management that is more tactical than ideological. It remains to be seen whether this rebalancing signals a lasting trend among institutional investors or a simple arbitrage dictated by volatility.
