Bitcoin and Ether exchange-traded funds recorded a combined $1.1 billion in net inflows last week, according to BlockBeats, marking a break from the mostly persistent outflow trend seen through much of 2026. The report said institutional money had started moving back into crypto assets through ETF products.
BlackRock’s spot Bitcoin ETF, IBIT, was the dominant source of demand. It accounted for about 80% of total inflows into Bitcoin ETFs during the week, making it the largest single channel for fresh capital entering the segment.
Even with the rebound in fund flows, trading activity remained weak. BlockBeats said weekly BTC ETF trading volume fell to its second-lowest level since October 2024, showing that stronger inflows did not translate into a broad pickup in market turnover.
The report also noted that both BTC and ETH ETFs had previously faced sustained outflow pressure before the latest reversal in flows.
Bitcoin and Ether ETFs posted a combined $1.1 billion in net inflows last week, BlockBeats reported on Aug. 15, ending what it described as a mostly persistent period of net outflows through much of 2026. The move points to a return of institutional capital into crypto asset products.
IBIT led Bitcoin ETF inflows
Among Bitcoin ETFs, BlackRock’s IBIT was the main source of fresh money, accounting for about 80% of total inflows into the Bitcoin ETF segment for the week. The report said BTC and ETH ETFs had both been under sustained outflow pressure before the latest turnaround.
Trading activity stayed muted
Fund flows improved, but trading volume did not show the same strength. According to BlockBeats, weekly BTC ETF trading volume fell to its second-lowest level since October 2024.
The report added that ETF flows turned sharply as market sentiment improved and institutional investors increased digital-asset allocations again.
