Mubadala Investment Company raised its stake in BlackRock’s iShares Bitcoin Trust by 16% to $565,616,051 in Q1 2026. The increase continues an unbroken accumulation streak and forms part of Abu Dhabi's strategy to diversify sovereign assets away from oil dependency.
Abu Dhabi sovereign wealth fund Mubadala Investment Company increased its holdings in BlackRock’s iShares Bitcoin Trust (IBIT) during the first quarter of 2026. A 13F filing shows the fund owned 14,721,917 shares worth $565,616,051 at the close of March 31, 2026.
This represents a 16% rise from the 12,702,323 shares reported at the end of Q4 2025.
The latest disclosure continues an uninterrupted buying run that started in Q4 2024, when Mubadala first revealed bitcoin exposure of at least $436 million. A subsequent Q1 2025 filing listed 8,726,972 shares valued at $408.5 million. By December 31, 2025, the position had grown to 12.7 million shares worth $630.6 million — reflecting a 46% increase in that single quarter. The newest report adds roughly 2 million more shares, keeping the holding above the half-billion-dollar level for the third consecutive quarter.

Mubadala oversees a global portfolio exceeding $330 billion in assets spanning technology, healthcare, infrastructure, private equity, and public markets. Its mandate focuses on delivering returns to the Abu Dhabi government while decreasing the emirate’s reliance on oil revenues. Bitcoin, held via the regulated IBIT vehicle, ranks among the fund’s most prominent public-market exposures. As of Q4 2024, IBIT already stood as Mubadala’s second-largest position by a wide margin, behind only its longer-term investment in Arm Holdings.
Abu Dhabi’s sovereign bitcoin purchases extend beyond Mubadala. Al Warda Investments, linked to the Abu Dhabi Investment Council that operates under the Mubadala umbrella, has also accumulated IBIT shares. It reported 8.2 million shares valued at approximately $408 million at year-end 2025. Together the two Abu Dhabi entities held more than $1 billion in IBIT as of December 31, setting a benchmark for Gulf Cooperation Council sovereign involvement in regulated bitcoin products.
