Abu Dhabi’s sovereign investment vehicle, Mubadala Investment Company, has expanded its holdings in BlackRock’s iShares Bitcoin Trust (IBIT). Regulatory filings submitted today indicate that as of March 31, 2026, the company possessed 14,721,917 shares, with a market value of $565,616,051.
This represents a 16% expansion compared to the 12,702,323 shares the fund possessed at the conclusion of Q4 2025.
This latest disclosure continues a sustained period of acquisitions that commenced in Q4 2024, when Mubadala initially revealed its bitcoin holdings, valued at a minimum of $436 million. The fund augmented its holdings via a Q1 2025 filing, showing 8,726,972 shares valued at $408.5 million, subsequently escalating to 12.7 million shares worth $630.6 million by December 31, 2025 – a notable 46% surge within a single quarter. The filing today adds an additional 2 million shares to its portfolio, maintaining its position above the half-billion dollar threshold for the third consecutive quarter.
Mubadala oversees a worldwide asset portfolio valued at over $330 billion, spanning sectors such as technology, healthcare, infrastructure, private equity, and public markets. Its objective is to generate returns for the Abu Dhabi government while diminishing the emirate’s reliance on oil-derived income. Bitcoin, accessed through the established IBIT framework, has emerged as one of the fund’s most prominent publicly traded investments.
As of Q4 2024, IBIT had already become Mubadala’s second-largest investment by a substantial margin, ranking behind a long-term investment in Arm Holdings.
Abu Dhabi’s bitcoin acquisitions
Abu Dhabi’s sovereign accumulation strategy is not limited to Mubadala. Al Warda Investments, an entity connected to the Abu Dhabi Investment Council—which operates under the Mubadala umbrella—has also been actively increasing its IBIT stake, reporting 8.2 million shares valued at roughly $408 million at the close of 2025. Together, these two Abu Dhabi entities held over $1 billion in IBIT as of December 31, signifying a significant milestone for sovereign entities within the Gulf Cooperation Council investing in regulated bitcoin products.
The Q1 2026 filing emerges amid widespread institutional and governmental interest in bitcoin. Goldman Sachs reported total crypto exposure of approximately $2.36 billion through IBIT and other avenues, while Jane Street disclosed holdings of 20.3 million IBIT shares valued at $790 million at the end of Q4 2025.
On the governmental side, Texas became the first U.S. state to acquire bitcoin for its strategic reserves during the same timeframe.
Similarly, recent financial disclosures reveal that the Trump family trust acquired shares in several bitcoin-associated companies—including Coinbase, MARA Holdings, and Strategy—during the first quarter of 2026, as the administration pursues a more favorable policy stance toward cryptocurrencies.
The filings indicated thousands of transactions totaling between $220 million and $750 million.
