Mubadala Investment Company increased its exposure to Bitcoin during the fourth quarter of 2025 by expanding its position in BlackRock’s iShares Bitcoin Trust ETF, according to a regulatory filing.

The sovereign wealth fund raised its holdings in the exchange-traded fund by 46% compared with the previous quarter, bringing its total to 12.7 million shares as of December 31st. 

The Abu Dhabi Investment Council (ADIC), an independently operated unit of Mubadala, also increased its stake by 3% to 8.2 million shares through a subsidiary.

Based on the filings, the combined value of their positions exceeded $1 billion. The specific prices at which the shares were acquired were not disclosed.

IBIT, which tracks the price of Bitcoin, declined more than 23% in the fourth quarter of 2025 and has fallen by over 20% so far in 2026. 

Bitcoin has been under pressure since retreating from its October high of $126,000, entering a four-week downturn that brought the price to approximately $67,000 amid broader market volatility.

A spokesperson for ADIC stated that the fund is building an allocation to Bitcoin as part of a long-term diversification strategy and described Bitcoin “as a store of value similar to gold.”

Abu Dhabi is home to investment entities overseeing nearly $2 trillion in assets.
