Notably, activity in Ethereum investment vehicles surged past all previous weekly records, following a relatively quiet period with most trading concentrated in the past six weeks.

Ethereum ETFs Smash Records

Commenting on the recent surge in Ethereum ETFs, Nate Geraci, president of NovaDius Wealth Management, highlighted that spot Ethereum ETFs completely shattered the previous weekly volume record, reflecting unprecedented investor interest.

“Spot eth ETFs absolutely obliterated previous weekly trading volume record. Wonder if there are any “no demand” naysayers still out there,” he tweeted.

Ethereum ETFs have also outperformed bitcoin ETFs in recent inflows. Between August 11 and August 15, Ethereum investment vehicles collected $2.85 billion, signaling strong demand for the asset.

On August 11 alone, they saw inflows of $1.018 billion, marking the largest single-day inflow ever recorded for a U.S. spot Ethereum ETF, according to analytics platform Farside.

Since their introduction, these ETFs have gathered a total of $12.67 billion in net inflows. Their combined net asset value now stands at $28.15 billion, representing roughly 5.34% of Ethereum’s overall market capitalization.

By comparison, spot Bitcoin ETFs posted a smaller weekly inflow of $547.82 million over the same period. Since launch, bitcoin ETFs have accumulated $54.97 billion in net inflows, with a total net asset value of $151.98 billion, equal to about 6.54% of Bitcoin’s market capitalization.

Bitcoin and Ethereum Price Performance

Meanwhile, Bitcoin reached a new all-time high on August 14, briefly touching $124,000 before retreating to around $117,600. The pullback followed weaker U.S. economic data that weighed on market sentiment.

At the same time, Ethereum traded near $4,800 before correcting to approximately $4,400. The asset has risen by more than 70% year-over-year, reflecting a strong performance that coincides with surging ETF activity.

This trend highlights the increasing importance of crypto ETFs in driving capital flows. Ethereum ETFs, in particular, appear to be attracting significant attention from market participants.

Overall, the latest data shows an apparent acceleration in activity for Ethereum investment products. While bitcoin ETFs remain substantial in size, their recent inflow growth has been slower compared with their Ethereum counterparts.
