Bitcoin ETFs See Strongest Week Since October 2025 with $1.9 Billion in Net Inflows

U.S. spot Bitcoin ETFs pulled in $1.9 billion in net inflows during the week ending August 21, 2026, their strongest week since October 2025.

This reversal of a combined $392 million outflow from the previous week is significant, as it shows that institutional and retail money are positioning themselves in crypto, separate from whatever the price chart shows.

A fund flow measures the net amount of money entering or leaving an ETF over a set period, usually a single trading day or a week. It's different from the ETF's share price, which reflects what a share is currently trading for on an exchange.
