Abu Dhabi’s sovereign wealth fund, Mubadala Investment Company, has significantly expanded its stake in BlackRock’s iShares Bitcoin Trust (IBIT), cementing its position as a major institutional holder of regulated bitcoin products. According to a 13F filing released today, Mubadala reported ownership of 14,721,917 shares in IBIT, valued at $565,616,051 as of March 31, 2026.

This latest disclosure signifies a substantial 16% increase from the 12,702,323 shares the fund held at the close of Q4 2025. The accumulation streak for Mubadala in IBIT began in Q4 2024, when it first disclosed bitcoin exposure totaling at least $436 million. The fund continued to build its position through Q1 2025, reporting 8,726,972 shares valued at $408.5 million. By December 31, 2025, its holdings had surged to 12.7 million shares, worth $630.6 million, marking a robust 46% jump within a single quarter. The most recent Q1 2026 filing adds another 2 million shares to this impressive ledger, pushing Mubadala's IBIT position beyond the half-billion-dollar mark for the third consecutive quarter.

Mubadala Investment Company manages a vast global portfolio exceeding $330 billion in assets, spanning diverse sectors such as technology, healthcare, infrastructure, private equity, and public markets. Its core mandate is to generate sustainable returns for the Abu Dhabi government while actively contributing to the emirate's economic diversification efforts, reducing its traditional reliance on oil revenues. Within this expansive portfolio, bitcoin, accessed through the regulated IBIT structure, has rapidly emerged as one of the fund's most prominent public market positions. As of Q4 2024, IBIT was already Mubadala’s second-largest holding, surpassed only by a long-term stake in Arm Holdings.

The sovereign accumulation of bitcoin is not confined solely to Mubadala. Other Abu Dhabi-based entities are also making strategic moves into the digital asset space. Al Warda Investments, an entity closely associated with the Abu Dhabi Investment Council—which itself operates under the broader Mubadala umbrella—has similarly been building an IBIT position. At year-end 2025, Al Warda reported holdings of 8.2 million shares, worth approximately $408 million. Combined, these two Abu Dhabi vehicles held over $1 billion in IBIT as of December 31, 2025, a significant milestone highlighting the growing participation of Gulf Cooperation Council (GCC) sovereign entities in regulated bitcoin investment products.

The Q1 2026 filing by Mubadala arrives amid a broader global trend of increasing institutional and governmental interest in bitcoin and other cryptocurrencies. Major financial players are also expanding their exposure: Goldman Sachs disclosed approximately $2.36 billion in total crypto exposure through IBIT and various other vehicles, while Jane Street reported holding 20.3 million IBIT shares valued at $790 million at the close of Q4 2025. On the sovereign front, Texas made headlines by becoming the first U.S. state to acquire bitcoin for a strategic reserve during the same period. Furthermore, 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, aligning with the administration's advancing crypto-friendly policy agenda. These filings revealed thousands of trades collectively valued between $220 million and $750 million.
