UBS has tripled its stake in BlackRock’s iShares Bitcoin Trust to approximately $90 million, representing 2.5 million shares. The Swiss bank significantly expanded this position since early 2024, when it started with only 3,600 shares worth less than $150,000. The trajectory is notable: after $27.2 million at the end of 2025, the position had declined to $14 million in May 2026 before surging to $90 million. Across the market, 1,560 organizations collectively held IBIT shares worth more than $27 billion in Q1 2026, with banks as a group increasing their positions while some hedge funds were pulling back.
