Bitcoin spot ETF suffers heavy losses: net outflow of $1.33 billion in a single week, marking the worst record in nearly a year

According to SoSoValue data, the US Bitcoin spot ETF experienced its worst weekly performance since February 2025, with a total outflow of up to $1.33 billion within just four trading days last week. In terms of daily capital flows, Wednesday was the worst day, with as much as $709 million in funds withdrawn from the Bitcoin ETF; Tuesday saw a net outflow of $483 million; although selling pressure eased slightly on Thursday and Friday, decreasing to $32 million and $104 million respectively, the overall downward trend for the week was already set. This wave of capital fleeing is the most severe since late February 2025. At that time, the Bitcoin ETF lost $2.61 billion in just one week, and Bitcoin prices plummeted from a high of $109,000 to below $80,000. Despite recent massive capital outflows, since the US Bitcoin spot ETF was launched in January 2024, the total net inflow has still reached $56.5 billion. Currently, the total net assets of all Bitcoin ETFs are approximately $115.9 billion, indicating that long-term capital has not fully exited. Ethereum spot ETFs also experienced withdrawals last week, with a total net outflow of $611 million, and Wednesday recorded the worst day, with a net outflow of $298 million. As of now, the total net assets of Ethereum spot ETFs are approximately $17.7 billion, with cumulative net inflows of $12.3 billion since its launch in July 2024.
