Ethereum Spot ETFs See Highest Daily Inflow Since October 2025

Ethereum's spot exchange-traded funds (ETFs) have seen significant growth in recent days, with the highest daily inflow since October 28, 2025. According to metrics from SoSoValue, analyzed by Finbold on August 21, U.S. spot Ethereum ETFs recorded a total net inflow of $220.77 million on Thursday. This marks a substantial increase compared to the last time these funds closed their daily cash flow with over $220 million, which was nine months and 24 days ago.

The largest spot ETH ETF backed by BlackRock Inc., iShares Ethereum Trust ETF (ETHA), saw a net inflow of $173.3 million, increasing its Ethereum holdings to 3.08 million ETH valued at about $7.4 billion. Meanwhile, BlackRock's iShares Staked Ethereum Trust ETF (ETHB) recorded the second-highest daily cash inflow with roughly $35.90 million, bringing its total ETF holdings to $765.96 million.

This influx of capital into spot ETH ETFs has contributed to a 28% surge in the price of ETH over the past week, reaching $2,409 at the time of reporting. If this trend continues, it's possible that ETH could break above its current resistance level, which has been in place since February.

The increased demand from whales and institutional investors is a positive sign for Ethereum's market capitalization, which now stands at $289.4 billion with a 24-hour average traded volume of $30.85 billion.
