INSTITUTIONAL | Why the World’s Largest Spot Bitcoin ETF Recorded Near-Record Daily Outflow

BlackRock’s iShares Bitcoin Trust (IBIT) recorded $405.3 million in net outflows, its second-largest daily withdrawal since launching in January 2024 as investors reduced exposure to Bitcoin. Other U.S. spot Bitcoin ETFs collectively lost $398.6 million during the session extending a period of sustained withdrawals amid market uncertainty. In June 2026 , IBIT recorded its largest single-day outflow on record so far, including a massive block transaction that underscored growing institutional selling.
