Harvard University’s endowment is said to have significantly scaled back its cryptocurrency exposure, while Abu Dhabi’s Mubadala Investment Company has steadily expanded its commitment to Bitcoin. Recent 13F filings with the US Securities and Exchange Commission (SEC) highlight these shifts among major institutional players navigating volatile markets.

Harvard Management Company, which oversees the university’s substantial endowment, fully liquidated its position in BlackRock’s iShares Ethereum Trust ETF (ETHA) during the first quarter of 2026.

This exit came after the endowment had initiated the stake in late 2025, when it acquired shares valued at approximately $86.8 million.

At the same time, Harvard trimmed its holdings in BlackRock’s iShares Bitcoin Trust (IBIT) by about 43%, reducing from roughly 5.35 million shares at the end of 2025 to 3,044,612 shares, now valued around $117 million.

This reduction follows an earlier 21% cut in the prior quarter. As a result, IBIT no longer ranks among Harvard’s top holdings, surpassed by major equities such as TSMC, Alphabet, Microsoft, and even the SPDR Gold Trust.

The moves reflect a broader rebalancing, potentially driven by performance concerns—Ethereum-related positions had faced notable declines earlier in the year—or a reassessment of risk in the endowment’s portfolio amid broader market uncertainty.

In sharp contrast, Abu Dhabi’s sovereign wealth fund Mubadala continued its consistent accumulation of Bitcoin exposure.

The fund increased its IBIT stake by 16% in Q1 2026, adding shares to reach 14,721,917 holdings valued at approximately $565.6 million as of March 31.

This marks the latest step in a multi-quarter buying streak that began in late 2024, with Mubadala steadily building one of the more prominent sovereign positions in regulated Bitcoin products.

Mubadala’s strategy underscores a long-term conviction in Bitcoin as a diversifier and store of value, aligned with the fund’s broader mandate to generate returns and reduce reliance on traditional oil revenues.

Related Abu Dhabi entities, such as those tied to the Abu Dhabi Investment Council, have also maintained or grown parallel exposures, contributing to over $1 billion in combined IBIT holdings at the end of 2025.

These developments occur against a backdrop of maturing institutional adoption of crypto ETFs.

While universities like Harvard appear more cautious—potentially prioritizing capital preservation amid endowment responsibilities—sovereign funds like Mubadala treat Bitcoin as a strategic asset class with enduring potential.

Other institutions showed mixed activity: some US university endowments held steady or explored altcoin staking products, while banks adjusted through options hedging.

The divergence highlights how different investors weigh Bitcoin and Ethereum’s risk-reward profiles.

Harvard’s pullback may signal short-term caution following earlier volatility, whereas Mubadala’s ongoing purchases reflect confidence in Bitcoin’s role within diversified global portfolios, even during price fluctuations.

As crypto markets evolve and regulatory clarity improves, such filings offer a window into how sophisticated players are positioning themselves. The contrast between Harvard’s reduction and Abu Dhabi’s expansion may foreshadow varied institutional paths forward, with implications for liquidity, ETF flows, and broader market sentiment in the quarters ahead.
