Recent SEC disclosures reveal that Abu Dhabi’s Mubadala Investment Company expanded its holdings in BlackRock’s iShares Bitcoin Trust by 16% during the opening quarter of 2026. The government-backed investment entity now controls 14.7 million shares with an estimated market value of $566 million.
The Q1 2026 data shows a sustained increase in share count, despite a minor decline in dollar valuation from the $630.6 million recorded at 2025’s conclusion. This discrepancy stems from Bitcoin’s price contraction from its late-2025 peak levels, not from any sell-off by the fund.
Five Consecutive Quarters of Bitcoin Accumulation
Mubadala’s initial Bitcoin ETF disclosure appeared in Q4 2024 with approximately $436 million in holdings. The portfolio value temporarily decreased to $408.5 million during Q1 2025 amid Bitcoin price corrections, before climbing to $630.6 million by December 31, 2025, when Bitcoin exceeded the $100,000 threshold.
The investment firm has expanded its holdings during every reporting cycle since inception. This unbroken five-quarter accumulation pattern demonstrates a calculated, sustained approach rather than tactical short-term positioning.
Mubadala isn’t the only Abu Dhabi institution with significant Bitcoin ETF exposure. Al Warda Investments, connected to the Abu Dhabi Investment Council, maintained a separate position of 8.2 million BlackRock Bitcoin ETF shares worth approximately $408 million as of Q4 2025. Together, Abu Dhabi-affiliated sovereign entities controlled over $1 billion in the ETF by year’s end.
The Abu Dhabi Investment Council previously tripled its Bitcoin ETF allocation during Q3 2025, marking one of the most substantial quarterly increases among sovereign investors.
BlackRock’s iShares Bitcoin Trust continues to dominate as the world’s largest spot Bitcoin ETF, controlling over 600,000 Bitcoin as of April 2026. This represents approximately triple the holdings of its nearest competitor, Fidelity.
Norway’s Norges Bank has similarly emerged in recent 13-F submissions as a shareholder, further cementing the ETF’s position as the preferred vehicle for nation-state Bitcoin investment.
University Endowments Split on Crypto Strategy
Institutional approaches varied considerably. Harvard University decreased its BlackRock Bitcoin ETF allocation by 43% to 3.04 million shares. The prestigious institution also liquidated its entire $86.8 million stake in BlackRock’s spot Ethereum ETF.
Dartmouth College pursued a contrasting strategy. The Ivy League institution revealed among the earliest documented endowment investments in a Solana ETF, acquiring $3.67 million of the Bitwise Solana Staking ETF.
Barclays reported a holding of 4.46 million BlackRock Bitcoin ETF shares accompanied by put and call options. Hong Kong-based investment firm Laurore decreased its allocation by 22%.
The Q1 2026 13-F submissions reveal widening institutional approaches to cryptocurrency investments. Gulf-region sovereign wealth funds continue methodically building exposure, while certain university endowments are reducing or eliminating positions.
Mubadala’s uninterrupted accumulation pattern spanning five reporting periods represents one of the most definitive long-term institutional Bitcoin commitments among government-sponsored investment vehicles worldwide.
