U.S. Bitcoin ETFs Experience Record $4.5 Billion Outflow in June

In June, U.S. spot bitcoin exchange-traded funds (ETFs) experienced a record outflow of $4.5 billion, marking their most significant decline since their launch in January 2024, as reported by SoSoValue.

This outflow exceeded the previous high of $3.48 billion recorded in February 2025 by 29%.

The largest contributor to this downturn was BlackRock's IBIT fund, which alone accounted for $3.55 billion of the outflows, including $212 million on June 30. This marked the fund's ninth consecutive day of withdrawals. As a result, total ETF assets plummeted from about $83 billion at the beginning of June to roughly $71 billion.

Two major events likely influenced this trend. The first was the June 12 launch of SpaceX, which attracted billions in risk capital and set new records for retail trading on its debut, raising a total of $75 billion. The second was a pivotal meeting led by new Federal Reserve Chair Kevin Warsh just five days later, which indicated a shift toward potential interest rate hikes, causing institutions to reduce their exposure to volatile assets.
