According to a new 13F filing and Cointelegraph, Abu Dhabi’s sovereign wealth fund increased its BlackRock IBIT position to 14.7 million shares as of March 31, 2026, highlighting continued institutional demand for regulated Bitcoin exposure.
Abu Dhabi’s sovereign wealth fund Mubadala Investment Company increased its holding in BlackRock’s iShares Bitcoin Trust to 14,721,917 shares valued at $565,616,051 as of March 31, 2026, according to a 13F filing. The position rose 16% from 12,702,323 shares at the end of Q4 2025, extending an accumulation streak that began in Q4 2024. Cointelegraph separately described the stake as nearly $660 million, creating a valuation discrepancy, but both reports point to continued institutional demand for regulated Bitcoin exposure through exchange-traded products. Earlier disclosures cited at least $436 million in Bitcoin exposure in Q4 2024, 8,726,972 shares worth $408.5 million in Q1 2025, and 12.7 million shares worth $630.6 million by December 31, 2025.
