Abu Dhabi-based Mubadala Investment Co. and its subsidiary increased their positions in BlackRock's Bitcoin ETF in the fourth quarter of 2025, despite the sharp decline in cryptocurrency prices.
The sovereign wealth fund increased its stake in the iShares Bitcoin Trust ETF by 46% to 12.7 million shares as of December 31, 2025, according to a regulatory filing. Meanwhile, the Abu Dhabi Investment Council (ADIC), an independently managed unit of Mubadala, increased its position by 3% to 8.2 million shares through a subsidiary.
Collectively, their combined holdings were valued at more than $1 billion, according to the funds' filings, although specific purchase prices were not disclosed. The ETF, which tracks the price of Bitcoin, lost more than 23% in the fourth quarter of 2025 and declined by more than a fifth in 2026.
Bitcoin is under pressure after falling from its October peak of $126,000. The cryptocurrency is in a four-week decline, falling to $67,000 amid broader market volatility.
ADIC CEO Saeed Al Mazrouei told Bloomberg News earlier this month that the fund is making bold investments in several sectors, including blockchain startups.
Abu Dhabi manages funds overseeing nearly $2 trillion in assets, some of which have recently expanded into the crypto sector. MGX, an artificial intelligence investor co-founded by Mubadala, acquired a $2 billion stake in Binance, the world's largest cryptocurrency exchange, in 2025.
