Harvard Reduces BlackRock Bitcoin ETF Position
Harvard’s endowment cut its position in BlackRock’s iShares Bitcoin Trust, also known as IBIT.

The endowment manages about $53 billion in assets, based on the provided figures.
Its remaining IBIT stake still placed Bitcoin exposure inside the portfolio. However, the position was smaller than earlier filings showed.
SEC 13F filings show holdings at quarter-end. They do not show every trade made during the quarter. They also do not explain why an institution changed a position.
Endowment Fully Exits Spot Ethereum ETF
Harvard also fully exited its position in BlackRock’s spot Ethereum ETF. The position was previously valued at about $86.8 million.
The filing showed no remaining stake by the end of Q1 2026. The exit came after Harvard held the Ether ETF position in the prior quarter.
The reported sale removed direct spot Ethereum ETF exposure from the filing. However, the filing does not show the exact sale dates.
The move came during a period of weaker crypto prices, based on the provided market context.
Some market watchers noted the timing because the stake was held for a short period. Still, the filing only records the end position.
The Ethereum ETF exit was reported alongside the IBIT reduction.
Together, the changes showed lower exposure to both Bitcoin and Ether ETFs. The filing did not include comments from Harvard on the decision.

Combined holdings across Mubadala and Al Warda Investments surpassed $1 billion at the end of 2025.
The figure showed Abu Dhabi’s growing exposure to Bitcoin ETF products. It also placed the region among notable institutional holders.
ADIC, an Abu Dhabi entity operating under Mubadala, previously called Bitcoin a “long term diversification strategy.”
It compared Bitcoin to gold in portfolio planning. It also said both assets may hold roles as the economy becomes more digital.
The buying pattern points to a longer investment horizon. Mubadala’s activity differs from short-term trading behavior seen in public markets.
The latest filing showed continued interest in IBIT while Harvard reduced crypto ETF exposure.
