As Ethereum ($ETH) added more than $12.4 billion to its market capitalization over the past 24 hours, its United States spot Exchange-Traded Funds (ETFs) recorded their highest daily inflow since October 28, 2025, on August 20.
The U.S. spot Ethereum ETFs registered a daily total net inflow of $220.77 million on Thursday, according to metrics from SoSoValue, as analyzed by Finbold on August 21. The last time these funds closed their daily cash flow with over $220 million was nine months and 24 days ago, when they attracted $246.02 million.
These spot $ETH ETFs have seen a gradual increase in positive cash inflows over seven consecutive days, thus signaling a renewed demand from whales and institutional investors.
The highest daily cash inflow was through iShares Ethereum Trust ETF (ETHA), the largest spot $ETH ETF backed by BlackRock Inc. (NYSE: BLK). Specifically, ETHA closed Thursday with a net inflow of $173.3 million, thus increasing its Ethereum holdings to 3.08 million $ETH valued at about $7.4 billion at press time.
Notably, BlackRock’s iShares Staked Ethereum Trust ETF (ETHB) recorded the second-highest in daily cash inflow, roughly $35.90 million, thereby increasing its ETF holdings to $765.96 million. As a result, U.S. spot $ETH ETFs have total net assets of $13.58 billion at the time of publication.
Here is what Ethereum whales are signaling
As investors flocked to gain exposure to Ethereum via spot ETFs over the past week, $ETH price has surged by more than 28%, trading at $2,409 at the time of reporting. As such, the crypto asset has a market capitalization of $289.4 billion, with a 24-hour average traded volume of $30.85 billion.
From a technical analysis standpoint, $ETH price has retested a major resistance level that has been in place since the February crypto capitulation. If spot $ETH ETFs continue to accumulate aggressively in the coming days and weeks, $ETH price could break above its current resistance level.
