U.S. spot bitcoin and ether ETFs drew a combined $1.1 billion in inflows for the week ending August 7, according to SoSoValue data. Bitcoin funds alone took in $853.5 million while ether funds received $244.9 million.
The inflow marks a rebound for bitcoin ETFs after a period of weaker demand. Ether ETFs, which have drawn substantially smaller totals than their bitcoin counterparts since launching later, captured roughly one-quarter of the combined weekly total.
Spot bitcoin ETFs launched in the U.S. in January 2024 and have become the primary vehicle for institutional exposure to the cryptocurrency. The combined $1.1 billion inflow represents the magnitude of capital flows these products now channel weekly, though the scale varies considerably by week and by asset. Bitcoin ETF inflows have at times exceeded $500 million in a single week and other weeks fallen to near zero or negative.
Ether spot ETFs began trading in July 2024, four months after bitcoin. They have drawn smaller absolute volumes than bitcoin products, a pattern consistent with ethereum's smaller market cap and the later entry point of these funds into the ecosystem.
Weekly ETF inflows track movements tied to macro conditions and crypto-specific events. SoSoValue tracks these flows across all U.S. registered spot ETF products in both asset classes and publishes the data publicly.
The $1.1 billion combined total for the week represents the level of institutional and qualified investor capital flowing into these vehicles on a weekly basis. Bitcoin ETFs have become the second-largest holder of bitcoin by some measures since their U.S. launch, accumulating holdings that now rank alongside major long-term holders.
