US-listed Bitcoin and Ethereum exchange-traded funds (ETFs) saw significant inflows last week, totaling $2.6 billion in net inflows for the week ending August 21, 2026.

This marks their best weekly performance since October 2025, with Bitcoin ETFs leading the surge by attracting nearly $1.9 billion and pushing trading volumes over $22 billion.

Ethereum ETFs added $697 million to this total, despite both types of ETFs remaining negative year-to-date and heading toward their first full year of net outflows since launching in 2024.

This inflow spike highlights renewed investor interest amid volatile crypto markets.
