TL;DR
-
U.S. spot Bitcoin ETFs posted $4.5 billion in net outflows in June, the largest monthly withdrawal since their launch in January 2024.
-
The funds extended their losing streak to nine consecutive trading days after another $222.6 million in outflows on June 30.
-
BlackRock's IBIT accounted for $3.55 billion of the month's withdrawals.
U.S. spot Bitcoin exchange-traded funds (ETFs) experienced their largest monthly outflow on record in June, with investors withdrawing $4.5 billion as macroeconomic uncertainty and shifting capital allocation weighed on demand for digital assets.
According to data from SoSoValue, the ETFs also recorded $222.6 million in net outflows on June 30, extending their negative streak to nine consecutive trading sessions.
The June selloff surpassed the previous monthly record of $3.48 billion, set in February 2025, by approximately 29%.
BlackRock's IBIT Leads Monthly Withdrawals
The largest contributor to June's outflows was BlackRock's iShares Bitcoin Trust (IBIT), the biggest U.S. spot Bitcoin ETF by assets under management.
IBIT alone recorded approximately $3.55 billion in net outflows during the month, accounting for the majority of total withdrawals across the sector.
Despite the recent selling pressure, U.S. spot Bitcoin ETFs have continued to attract significant long-term investment since their debut in January 2024.
Market participants say the record withdrawals reflect broader portfolio adjustments rather than declining confidence in Bitcoin itself.
Paul Howard, Senior Director at Wincent, said institutional investors are reducing exposure to higher-risk assets amid elevated interest rates, geopolitical tensions, and an increasingly cautious macroeconomic environment.
Rather than signaling weakening long-term conviction, Howard believes the ETF outflows are primarily the result of broader capital rotation.
SpaceX IPO May Have Diverted Investment Flows
Some analysts also point to the high-profile SpaceX initial public offering (IPO) as another factor behind the ETF withdrawals.
Maxime Seiler, CEO of STS Digital, said much of the institutional capital deployed into Bitcoin and spot ETFs over the past year has already been invested, leaving fewer new inflows available.
At the same time, the record-breaking SpaceX IPO reportedly attracted substantial investor interest.
According to CNN, the offering sold more than 555 million shares and raised approximately $75 billion, making it one of the largest public listings on record.
Seiler argues that some institutional investors shifted capital away from cryptocurrencies to participate in the IPO while awaiting new catalysts for the digital asset market.
Bitcoin Continues to Face Selling Pressure
The ETF outflows have coincided with a sharp decline in Bitcoin's price. Bitcoin is currently trading near $58,600, a level last seen consistently in September 2024.
Over the past month, the cryptocurrency has fallen approximately 20%, while posting a decline of roughly 45% over the past year.
In its latest market report, Bitfinex suggested Bitcoin could potentially fall toward $40,000 by the fourth quarter if market conditions continue to weaken.
Jerald David, CEO of Lynq, noted that ETF outflows reduce one important source of demand for spot Bitcoin, potentially increasing short-term price volatility.
Despite the record withdrawals, analysts generally do not view the ETF outflows as evidence of weakening long-term confidence in Bitcoin.
Total assets held by U.S. spot Bitcoin ETFs have declined to approximately $70.9 billion, down from peaks above $110 billion earlier this year.
However, cumulative net inflows since the funds launched remain positive at more than $51 billion, highlighting continued institutional adoption over the longer term.
Renna Ba, Head of Ecosystem at Morph, said the recent pullback appears to reflect a cooling in speculative positioning rather than a fundamental shift in investor sentiment.
She added that the long-term resilience of the cryptocurrency market will increasingly depend on real-world blockchain adoption and on-chain utility instead of speculative trading activity.
