U.S. spot Bitcoin ETFs recorded roughly $1.918 billion in net inflows during the five-session trading week from Monday, Aug. 17, through Friday, Aug. 21, measured in U.S. Eastern Time, according to SoSoValue’s spot BTC ETF dashboard. The figure reflects creations minus redemptions across the full U.S.-listed spot Bitcoin ETF segment, rather than gross subscriptions or the flow of any single fund. The source confirms the aggregate total and reporting window but does not independently provide a day-by-day or issuer-level breakdown. Weekly net creations are commonly used as a proxy for institutional and advised-money demand entering regulated Bitcoin exposure, although ETF flows and Bitcoin’s spot price can move independently. The segment has experienced oscillating flows, including periods of roughly $2.1 billion in net outflows over 30 days and sessions when Bitcoin ETFs gained funds while Ether ETFs lost them. The next key data point is the following week’s flow reading, which will indicate whether the $1.918 billion pace held, reversed, or accelerated into month-end.
