US-listed spot Bitcoin exchange-traded funds are suffering their worst month of withdrawals since launching in January 2024. According to market data, investors pulled a net total of $4.06 billion from the funds in June, eclipsing the previous record of $3.56 billion set in February 2025.
The exodus was defined by a historic losing streak. From mid-May into early June, the funds recorded 13 consecutive days of net outflows, the longest on record. A staggering $4.4 billion exited during that period alone. In a single week, net outflows hit $1.72 billion, with BlackRock’s iShares Bitcoin Trust absorbing the heaviest blow after seeing approximately $860 million leave the fund.
Bitcoin’s price has stagnated between $58,000 and $60,000 during this flight of capital. The combined assets under management for these products have fallen from roughly $104 billion, a decline accelerated by both the redemptions and the shrinking value of remaining holdings.
The sustained capital flight threatens the viability of smaller fund issuers. While giants like BlackRock and Fidelity can weather the storm, funds with thinner margins and lower asset bases face economic pressure if the negative trend continues. The launch of these products was initially seen as a guarantee of steady institutional demand, a narrative now facing its most serious test.
