US-listed spot Bitcoin ETFs experienced a record $4.06 billion in net outflows in June 2026, marking the worst month since these funds began trading in January 2024. This surpasses the previous high of $3.56 billion outflows in February 2025 and reflects a prolonged selling streak that started mid-May. The decline in assets under management, from $104 billion, is due to both withdrawals and Bitcoin price fluctuations around $58,000-$60,000. This trend raises concerns about the economic viability of smaller Bitcoin ETFs, though major players like BlackRock and Fidelity are better positioned to endure the downturn.
