Mubadala Boosts IBIT Stake to $565.6M as Harvard Exits Ethereum

Key Facts

Mubadala Investment Company increased its stake in the iShares Bitcoin Trust (IBIT) by 16% during the first quarter of 2026, bringing its total holding to 14.7 million shares. The total value of Mubadala's investment in the IBIT fund reached approximately $565.6 million according to Q1 disclosures. Meanwhile, reports indicate that Harvard University has liquidated its entire position in Ethereum ETFs.

Mubadala's calculated expansion into Bitcoin underscores a growing trend of Gulf sovereign wealth funds institutionalizing their crypto exposure, as IBIT maintains its lead over peers like the Fidelity Wise Origin Bitcoin Fund (FBTC) per market data. Research into recent filings suggests that while sovereign entities are scaling up, major US academic endowments are rotating out of Ethereum-linked products following a period of re-evaluating altcoin risk-adjusted returns.

Traders should monitor IBIT price levels, which stood at $38.45 (at close May 15, 2026). Looking ahead, upcoming catalysts such as the US Existing Home Sales data on May 21, 2026, could shift broader risk sentiment and impact institutional flows into digital asset exchange-traded products.
