Abu Dhabi’s Mubadala Investment Company has significantly increased its stake in BlackRock’s iShares Bitcoin Trust (IBIT), revealing ownership of 14,721,917 shares valued at approximately $565.6 million as of March 31, 2026, according to a recent 13F filing. This marks a 16% increase from the 12,702,323 shares held at the end of the previous quarter in 2025. This latest disclosure continues a trend of accumulation that began in the fourth quarter of 2024, when Mubadala first reported bitcoin exposure valued at over $436 million.
In subsequent filings, the fund demonstrated a rapid increase in its holdings, reporting 8,726,972 shares worth $408.5 million in the first quarter of 2025, and escalating to 12.7 million shares valued at $630.6 million by the end of 2025—a remarkable 46% increase in just one quarter. The latest filing again adds over 2 million shares, reinforcing Mubadala’s position in IBIT beyond the half-billion dollar threshold for the third consecutive quarter.
Mubadala, which manages a diverse global portfolio exceeding $330 billion across various sectors including technology, healthcare, and infrastructure, is focused on generating returns for the Abu Dhabi government while also reducing dependence on oil revenues. Notably, Bitcoin, accessed through the regulated IBIT, has emerged as one of the fund’s prominent public market investments. As of the end of 2024, IBIT stood as Mubadala’s second-largest holding, only surpassed by its long-term investment in Arm Holdings.
Additionally, Abu Dhabi’s investment landscape reflects not only Mubadala’s activities. Al Warda Investments, associated with the Abu Dhabi Investment Council—operating under the same umbrella—has also been expanding its IBIT position, reporting 8.2 million shares valued at around $408 million at the close of 2025. Together, these two entities now hold over $1 billion in IBIT, marking a significant moment for sovereign investment in regulated bitcoin products within the Gulf Cooperation Council.
This move by Mubadala and its affiliated institutions comes amid a growing institutional and governmental interest in Bitcoin. Notably, Goldman Sachs reported approximately $2.36 billion in total cryptocurrency exposure through IBIT and other avenues, while Jane Street noted ownership of 20.3 million IBIT shares worth $790 million at the end of the previous year.
On the governmental front, Texas took the lead as the first U.S. state to procure Bitcoin for its strategic reserves during this period. In a related vein, financial disclosures indicated that the Trump family trust acquired shares in several Bitcoin-linked firms, including Coinbase and Marathon Digital Holdings, as part of a broader agenda aimed at fostering a more crypto-friendly policy environment. These filings revealed numerous trades with a total value fluctuating between $220 million and $750 million, underscoring the increased traction and acceptance of cryptocurrency in mainstream finance.
