Mubadala Boosts Bitcoin ETF Holdings to $566M in Q1 2026, 16% Increase Reported

Abu Dhabi’s sovereign wealth fund Mubadala Investment Company has raised its position in BlackRock’s iShares Bitcoin Trust (IBIT) by 16%, reaching a total stake of 14,721,917 shares valued at $565,616,051 as of March 31, 2026. This disclosure was made in a 13F filing released today.

The increase marks a 16% rise from the 12,702,323 shares held at the end of Q4 2025. This extends an uninterrupted accumulation streak that began in Q4 2024, when Mubadala first disclosed bitcoin exposure worth at least $436 million.

Mubadala’s Bitcoin Investment Growth

The fund’s bitcoin holdings have grown significantly over the past two years:

• Q1 2025 filing: 8,726,972 shares valued at $408.5 million
• December 31, 2025: 12,702,323 shares valued at $630.6 million (46% quarterly increase)
• March 31, 2026: 14,721,917 shares valued at $565.6 million

Today’s filing adds another 2 million shares to the ledger, pushing the position past the half-billion dollar mark for the third consecutive quarter.

Mubadala’s Portfolio and Bitcoin’s Role

Mubadala manages a global portfolio exceeding $330 billion in assets across technology, healthcare, infrastructure, private equity, and public markets. Its mandate focuses on generating returns for the Abu Dhabi government while reducing the emirate’s 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 the fund’s second-largest holding by a wide margin, trailing only a longer-term stake in Arm Holdings.

Abu Dhabi’s Broader Bitcoin Investments

Abu Dhabi’s bitcoin accumulation extends beyond Mubadala. Al Warda Investments, an entity tied to the Abu Dhabi Investment Council — which operates under the Mubadala umbrella — has also been building an IBIT position. As of year-end 2025, Al Warda reported holding 8.2 million shares worth approximately $408 million.

Combined, the two Abu Dhabi vehicles held more than $1 billion in IBIT as of December 31, 2025, marking a milestone for Gulf Cooperation Council sovereign participation in regulated bitcoin products.

Broader Institutional and Governmental Bitcoin Interest

The Q1 2026 filing coincides with growing institutional and governmental interest in bitcoin:

• Goldman Sachs: Disclosed approximately $2.36 billion in total crypto exposure through IBIT and other vehicles.
• Jane Street: Reported holding 20.3 million IBIT shares worth $790 million at Q4 2025 year-end.
• Texas: Became the first U.S. state to purchase bitcoin for a strategic reserve during the same period.

Additionally, new financial disclosures indicate that the Trump family trust purchased shares of several bitcoin-linked companies — including Coinbase, MARA Holdings, and Strategy — during the first quarter of 2026. The filings revealed thousands of trades worth between $220 million and $750 million overall, as the administration advances a more crypto-friendly policy agenda.
