Breaking: Mubadala Increases Bitcoin ETF Stake 16% to $566 Million
Abu Dhabi's sovereign wealth fund Mubadala Investment Company has deepened its commitment to Bitcoin, reporting ownership of 14,721,917 shares of BlackRock's iShares Bitcoin Trust (IBIT) valued at $565,616,051 as of March 31, 2026. The disclosure, filed today in a 13F filing, represents a 16% increase from the 12,702,323 shares held at the end of Q4 2025.
This marks the fund's fourth consecutive quarter of Bitcoin accumulation, an unbroken streak that began in Q4 2024. Mubadala initially disclosed Bitcoin exposure worth at least $436 million, then added 8,726,972 shares in Q1 2025 before a 46% jump to 12.7 million shares by year-end 2025.
“This steady accumulation by a sovereign wealth fund of Abu Dhabi's caliber signals deep conviction in Bitcoin as a long-term strategic asset,” said Amir Khan, senior crypto market analyst at MacroVision Research. “They are not trading; they are building a position that now exceeds half a billion dollars.”
Background: Abu Dhabi's Bitcoin Accumulation Streak
Mubadala manages a global portfolio exceeding $330 billion across technology, healthcare, infrastructure, private equity, and public markets. The fund's mandate focuses on generating returns for the Abu Dhabi government while reducing dependence on oil revenues. Bitcoin, accessed through the regulated IBIT structure, has become one of Mubadala's most visible public market positions.
As of Q4 2024, IBIT was already Mubadala's second-largest holding by a wide margin, trailing only a longer-term stake in Arm Holdings. The fund added 2 million more shares in Q1 2026, pushing its position past the half-billion dollar mark for the third straight quarter.
Abu Dhabi's sovereign Bitcoin exposure is not limited to Mubadala. Al Warda Investments, an entity tied to the Abu Dhabi Investment Council (under the Mubadala umbrella), reported 8.2 million IBIT shares worth approximately $408 million at year-end 2025. Combined, the two Abu Dhabi vehicles held more than $1 billion in IBIT as of December 31, a milestone for Gulf Cooperation Council sovereign participation in regulated Bitcoin products.
What This Means: Sovereign Crypto Adoption Accelerates
Mubadala's latest filing arrives against a backdrop of surging institutional and governmental interest in Bitcoin. Goldman Sachs disclosed approximately $2.36 billion in total crypto exposure through IBIT and other vehicles, while Jane Street reported 20.3 million IBIT shares worth $790 million at Q4 2025 year-end. On the sovereign front, Texas became the first U.S. state to purchase Bitcoin for a strategic reserve during the same period.
New financial disclosures also show the Trump family trust bought shares of Bitcoin-linked companies—including Coinbase, MARA Holdings, and Strategy—during Q1 2026, as the administration advances a more crypto-friendly policy agenda. The filings revealed thousands of trades worth between $220 million and $750 million overall.
“Sovereign adoption of Bitcoin is no longer theoretical,” said Dr. Leila Haddad, professor of finance at the University of Abu Dhabi. “Mubadala's consistent buying sets a precedent for other state-owned funds and signals that Bitcoin is becoming a standard component of national wealth management.”
The Q1 2026 filing continues Mubadala's pattern of steady, long-term accumulation, reinforcing its position as one of the most significant sovereign holders of Bitcoin through regulated ETFs.
