US-listed spot Bitcoin exchange-traded funds (ETFs) recorded their largest daily net outflows of June after Bitcoin fell below the $60,000 mark, reflecting continued caution among institutional investors amid ongoing market weakness.
According to data from SoSoValue, spot Bitcoin ETFs registered $696.3 million in net outflows on Thursday, surpassing the previous monthly high of $519.2 million recorded on June 2.
The latest withdrawals pushed total ETF outflows for June to $3.61 billion, while year-to-date net outflows climbed to $4.6 billion, highlighting sustained selling pressure across the sector.
The decline in fund flows comes as institutional demand for Bitcoin shows signs of slowing. Market observers have also noted that Strategy, the world’s largest corporate holder of Bitcoin, significantly reduced the pace of its cryptocurrency purchases during June.
Assets held by US spot Bitcoin ETFs have also fallen sharply. Total net assets have declined to approximately $72.6 billion, down about 57% from the record $169.5 billion reached in October 2025. Data from WalletPilot indicates that the funds collectively held around 1.24 million BTC, with roughly 63,500 BTC withdrawn over the past month.
Strategy acquired around 3,600 BTC during June, a sharp slowdown compared with approximately 25,000 BTC in May and more than 50,000 BTC in April. The company also recorded a rare net sale of 32 BTC earlier this month, fueling discussion over whether it should preserve cash while the market remains under pressure.
The company’s perpetual preferred stock, STRC, has also weakened, closing at $75.69, well below its intended $100 benchmark. The decline has prompted debate among analysts regarding Strategy’s Bitcoin acquisition strategy and risk management approach.
Despite investor concerns, some industry figures remain optimistic. Bitcoin advocate Samson Mow argued that STRC includes a “self-repairing mechanism” that limits new share issuance when the stock trades below its target price, potentially helping stabilize its value.
The latest ETF outflows underscore growing investor caution as Bitcoin continues to face price volatility and weaker institutional demand.
