US-listed Bitcoin ETFs have erased their 2026 flow deficit after attracting more than $1.7 billion this week, including $999 million on Sept. 21 and $715 million on Sept. 22. The products are approaching their strongest inflow week of the year, when they collected about $1.92 billion during the week ended Aug. 21. BlackRock’s iShares Bitcoin Trust drew roughly $1.02 billion over four trading sessions. The inflows have reversed a $5.69 billion year-to-date deficit recorded by July 13, with about $6.04 billion returning since that trough and the annual total reaching approximately $349 million in net inflows. Bitcoin has risen about 35% from roughly $64,100 to above $85,000 since August, while the funds absorbed about $4.6 billion. However, profit-taking intensified as Bitcoin reached $87,265 before slipping to $84,589, with short-term holders transferring about 47,600 profitable BTC to exchanges near $88,000. Santiment said unusually large ETF inflows have previously clustered around local turning points, although strong creations can continue supporting prices. Continued fund demand could help absorb selling, while weaker demand alongside elevated exchange deposits would leave Bitcoin more dependent on other spot buyers.
