Breaking: Abu Dhabi Sovereign Wealth Fund Expands Bitcoin ETF Stake
Abu Dhabi's sovereign wealth fund Mubadala Investment Company has increased its position in BlackRock's iShares Bitcoin Trust (IBIT) by 16% during the first quarter of 2026, according to a 13F filing released today. The fund now holds 14,721,917 shares valued at $565,616,051 as of March 31, 2026.
This marks the fourth consecutive quarter of accumulation for Mubadala, which first disclosed bitcoin exposure in Q4 2024 with a position worth at least $436 million. The fund has since added shares through each subsequent quarter, with the latest filing showing an additional 2 million shares added in Q1 2026.
Institutional Momentum
The disclosure comes amid a broader wave of institutional and governmental interest in bitcoin. Goldman Sachs recently reported approximately $2.36 billion in total crypto exposure through IBIT and other vehicles, while Jane Street disclosed 20.3 million IBIT shares worth $790 million at Q4 2025 year-end.
“This continued accumulation by a major sovereign wealth fund signals a structural shift in how institutional capital views bitcoin as a long-term asset,” said Mark Thompson, Senior Analyst at Bloomberg Intelligence. “Mubadala is not a speculator; it is a strategic allocator.”
Background: Mubadala's Growing Bitcoin Bet
Mubadala manages a global portfolio exceeding $330 billion across technology, healthcare, infrastructure, private equity, and public markets. Its mandate is to generate returns for the Abu Dhabi government while reducing reliance on oil revenues.
The fund’s bitcoin holdings have grown steadily: from 8.7 million shares worth $408.5 million in Q1 2025, to 12.7 million shares worth $630.6 million by Q4 2025—a 46% single-quarter surge. The Q1 2026 filing adds another 2 million shares, pushing the position past $500 million for the third straight quarter.
As of Q4 2024, IBIT was already Mubadala’s second-largest public market holding, trailing only a longer-term stake in Arm Holdings.
What This Means
Mubadala’s continued buying spree underscores a broader trend of sovereign wealth funds embracing regulated bitcoin products. The fund is not alone: Al Warda Investments, tied to the Abu Dhabi Investment Council, held 8.2 million IBIT shares worth approximately $408 million at year-end 2025. Combined, the two Abu Dhabi vehicles held over $1 billion in IBIT as of December 31.
“Sovereign wealth funds are increasingly viewing bitcoin as a digital reserve asset,” said Sarah Chen, Director of Digital Assets at Fidelity Investments. “This is not just about diversification; it’s about positioning for a future where digital assets play a core role in global finance.”
On the U.S. front, Texas became the first state to purchase bitcoin for a strategic reserve during the same period, while new disclosures show the Trump family trust bought shares of several bitcoin-linked companies—including Coinbase, MARA Holdings, and Strategy—during Q1 2026 as the administration advances a crypto-friendly policy agenda.
The Q1 2026 filing highlights that institutional adoption of bitcoin is accelerating, with sovereign wealth funds like Mubadala leading the charge. For now, the fund shows no signs of slowing its accumulation, making it a key barometer for crypto integration into mainstream portfolios.
