Abu Dhabi’s sovereign wealth fund, Mubadala Investment Company, disclosed a significant increase in its position in BlackRock’s iShares Bitcoin Trust (IBIT), reporting ownership of 12.7 million shares valued at approximately $630.6 million as of December 31.
This represents a 46% rise from the 8.7 million IBIT shares previously reported as of September 30. Mubadala manages a broad global portfolio spanning technology, healthcare, infrastructure, private equity and public markets, with assets under management exceeding USD 330 billion.
The fund’s strategy aims to generate sustainable returns for the Government of Abu Dhabi and support economic diversification beyond oil.
Also in Q4 2025, Abu Dhabi-based Al Warda Investments increased its holdings in IBIT to 8.22 million shares in Q4 2025, up from 7.96 million in Q3, continuing a strategy shift that began earlier in the year.
The firm, part of the Abu Dhabi Investment Council under Mubadala, has historically favored private investments, making this public BTC ETF allocation notable for the region.
In other words, Abu Dhabi investment vehicles together held over 20 million shares of BlackRock’s IBIT at the close of last year, with a combined value exceeding $1.1 billion.
