U.S. spot bitcoin funds have taken in $2.8 billion since the run began, and ether ETFs are matching it day for day. Three sessions are left to make August their best month since October 2025.

U.S. spot bitcoin ETFs drew $1.92 billion in net inflows during the week of August 17 to August 21, while ether funds added $697.18 million.

Spot bitcoin funds took in $337.56 million on Aug. 24, extending an unbroken run of inflows that has now put real money behind a rally that started with a short squeeze.
