Mubadala Lifts BlackRock IBIT Holdings 16% to $565.6M in Q1 2026 Filing

Abu Dhabi's Mubadala Investment Company increased its position in BlackRock's iShares Bitcoin ETF (IBIT) by 16% in Q1 2026, reporting 14.7 million shares worth $565.6 million. The disclosure shows the share count rose even as the reported dollar value slipped from Q4 2025 levels, which the report attributes to a pullback in bitcoin prices from late-2025 highs.
