According to a 13F filing released today, Abu Dhabi’s sovereign wealth fund, Mubadala Investment Company, has increased its investment in BlackRock’s iShares Bitcoin Trust (IBIT), revealing ownership of 14,721,917 shares valued at $565,616,051 as of March 31, 2026.
This represents a 16% increase from the 12,702,323 shares the fund held at the conclusion of Q4 2025.
The recent disclosure marks an uninterrupted accumulation trend that commenced in Q4 2024, when Mubadala first revealed its bitcoin exposure valued at a minimum of $436 million. The fund further enhanced its position in a Q1 2025 filing, reflecting 8,726,972 shares worth $408.5 million. By December 31, 2025, the total had surged to 12.7 million shares valued at $630.6 million, indicating a notable 46% increase within a single quarter. Today’s filing adds an additional 2 million shares, elevating the total position beyond the half-billion-dollar threshold for the third consecutive quarter.
Mubadala oversees a global portfolio surpassing $330 billion in assets across diverse sectors including technology, healthcare, infrastructure, private equity, and public markets. Its mandate focuses on generating returns for the Abu Dhabi government while minimizing the emirate’s reliance on oil revenues. Bitcoin, accessed through the regulated IBIT structure, has emerged as one of the fund’s most prominent public market investments.
As of Q4 2024, IBIT stood as Mubadala’s second-largest holding, significantly trailing only a long-term investment in Arm Holdings.
Abu Dhabi’s Bitcoin Investments
The accumulation of bitcoin assets by Abu Dhabi extends beyond Mubadala. Al Warda Investments, affiliated with the Abu Dhabi Investment Council and operating under the Mubadala umbrella, has also been increasing its IBIT position, reporting 8.2 million shares valued at approximately $408 million at the end of 2025. The collective holdings of these two Abu Dhabi entities surpassed $1 billion in IBIT as of December 31, marking a significant milestone for sovereign participation from the Gulf Cooperation Council in regulated bitcoin products.
The Q1 2026 filing occurs amidst broader institutional and governmental interest in bitcoin. Goldman Sachs has disclosed approximately $2.36 billion in total crypto exposure through IBIT and other investment vehicles, while Jane Street reported holdings of 20.3 million IBIT shares valued at $790 million at the end of Q4 2025.
At the sovereign level, Texas made headlines by becoming the first U.S. state to acquire bitcoin as part of a strategic reserve during the same timeframe.
In addition, recent financial disclosures indicate that the Trump family trust purchased shares of several bitcoin-related companies—including Coinbase, MARA Holdings, and Strategy—during the first quarter of 2026, as the administration pursues a more crypto-friendly policy agenda.
The filings revealed thousands of trades with total values ranging between $220 million and $750 million overall.
