Key points
- U.S. spot Ethereum ETFs pulled in $2.85 billion last week (Aug 11–15), the biggest weekly haul since launch.
- U.S. spot Bitcoin ETFs drew ~$548 million over the same period.
- The ETH surge was led by a record single-day net inflow of $1.01 billion on Aug 11.
- Flows underscore persistent institutional demand for both assets despite mid-week volatility.
What happened
U.S. spot Ethereum ETFs notched a new weekly high for net creations, attracting $2.85 billion between Monday, Aug 11 and Friday, Aug 15. That total was driven by exceptionally strong early-week demand, including $1.0188 billion on Monday alone— the largestj single-day net inflow in the ETH products’ history.
Bitcoin ETFs also saw healthy demand, taking in ~$547.6 million across the same trading week, highlightedx by a $230.8 million net inflow on Thursday.
By the numbers (Aug 11–15, 2025)
Ethereum (ETH) ETFs — daily net flows (US$):
- Mon $1,018.8M, Tue $523.9M, Wed $729.1M, Thu $639.6M, Fri –$59.3M
Total: $2,852.1M (~$2.85B).
Bitcoin (BTC) ETFs — daily net flows (US$):
- Mon $178.1M, Tue $65.9M, Wed $86.9M, Thu $230.8M, Fri –$14.1M
Total: $547.6M (~$548M).
Why it matters
- Signal of broadening participation: After the U.S. approved spot ETH ETFs (they began trading July 23, 2024), last week’s figures show continued mainstream uptake beyond Bitcoin, with creations requiring authorized participants to source spot ETH—supportive for liquidity and price discovery.
- Rotation dynamics: The gap between ETH and BTC weekly flows suggests periods when allocators tilt toward ETH exposure (e.g., portfolio rebalancing, relative-value views) while still maintaining net demand for BTC.
Market context and outlook
Flows arrived amid choppy price action but resilient risk appetite. Analysts will watch whether the ETH/BTC flow skew persists and whether the in-kind creation/redemption green light for crypto ETPs (approved July 29, 2025) lowers friction and sustains larger creations into both asset classes.
