U.S. spot Bitcoin ETFs log $1.26B weekly outflow; Ethereum ETFs extend streak to 10 days

BlockBeats reported that U.S. spot Bitcoin ETFs posted net outflows of about $1.26 billion for the week ended May 23, marking the biggest weekly withdrawal since late January and extending net redemptions to six straight trading days. Data showed roughly $649 million left the group on Monday alone; while the pace of selling moderated later in the week, flows remained negative overall. Traders cited higher U.S. Treasury yields, a firmer U.S. dollar and rising geopolitical risks as key drivers behind the pullback. Ethereum ETFs also stayed under pressure, recording net outflows for 10 consecutive trading days, the longest streak since March 2025. Weekly net outflows totaled about $216 million. BlackRock's iShares Bitcoin Trust (IBIT) holds about $61.1 billion in assets under management, while cumulative net inflows stand at roughly $3.7 billion, suggesting recent price swings have weighed on the value of holdings. By the end of the ETF session, Bitcoin was trading near $77,500 and Ethereum around $2,130, with broader crypto markets moving in a tight range. Despite the near-term drawdown, spot Bitcoin ETFs have attracted about $57.1 billion in cumulative net inflows since launch, with total assets under management of roughly $98.9 billion.
