US spot Bitcoin and Ether ETFs recorded $2.6 billion in combined net inflows for the week ending August 21, the strongest since October 2025.

Spot bitcoin ETFs pulled in $517 million and ether funds $189 million on Aug. 19, the strongest daily hauls in months, as a broad rally torched $2.7 billion in bearish bets.

Analysts attributed the inflows to the surprise crypto market rally driven by US Treasury Department's buyback expansion announcement.
