U.S. spot Bitcoin ETFs pulled in $217 million on Monday, resuming net inflows one trading day after a $202 million outflow snapped their nine-day buying streak, according to data from SoSoValue.
Spot Ether ETFs never broke stride, adding $88 million on Monday for an 11th straight day of net buying worth $1.6 billion, the longest run for the products since a 20-day streak that ended in July 2025. Bitcoin ETF net assets closed August just under $100 billion after briefly crossing that threshold on Aug. 27, before Friday’s outflow pulled them back. Cumulative net inflows since the funds launched in January 2024 now stand near $55 billion.
August was the strongest month of 2026 for Bitcoin ETFs by a wide margin, more than double April’s total, even as the funds still carry a net outflow of roughly $2.5 billion for the year. Friday’s lone outflow followed hawkish Jackson Hole commentary that pushed rate-hike expectations higher; Monday’s rebound suggests allocators treated the move as a one-session adjustment rather than the start of a reversal.
BTC traded near $78,000 early Tuesday, down about 0.4% since midnight and consolidating after last week’s short squeeze that lifted prices from below $63,000 to $81,400. This week’s flow data should help clarify whether institutional demand is holding steady heading into September, a month that has historically been weak for bitcoin.
