Led by giants such as BlackRock and Fidelity, funds are accelerating into the U.S. Ethereum spot ETF. On Monday, the single-day net inflow exceeded US$1 billion for the first time, and the total cumulative net inflow has exceeded the tens of billions of US dollars. According to the analysis, the strong inflow of funds reflects the increasing confidence of institutional investors in the long-term potential of Ethereum as a store of value and the base layer of Web3, viewing it as the "cornerstone" of the mainstreaming of cryptocurrency. Ethereum has increased by more than 45% in the past month.
The U.S. Ethereum spot ETF is experiencing an unprecedented investment boom. On Monday, its single-day net inflow exceeded the $1 billion mark for the first time, setting a historic milestone.
According to data provided by SoSoValue, on Monday, August 11,Nine U.S.-listed Ethereum spot ETFs attracted a total of $1.02 billion in net inflows. This is the first time these products have exceeded the $1 billion mark in a single trading day since their launch in July last year.
The inflow was led by asset management giants BlackRock and Fidelity. This record-breaking single-day performance not only pushed the cumulative net inflows of Ethereum spot ETFs to successfully exceed the tens of billions of dollars, but also highlighted that the market's investment enthusiasm for Ethereum far exceeded the modest performance of Bitcoin spot ETFs during the same period.
Analysts pointed out that this strong momentum reflects investors’ increasing recognition of Ethereum’s dual value—both as a store of value and as a foundational layer for decentralized finance (DeFi) and Web3 innovation. This wave of funding is seen as a clear signal of increasing institutional confidence, indicating that Ethereum may be established as "the cornerstone of mainstream cryptocurrency adoption."

BlackRock and Fidelity lead the way
Monday's inflow data showed the dominance of the market's top players was clear. According to SoSoValue data, BlackRock’s iShares Ethereum Trust (ETHA) topped the list, with a single-day net inflow of US$639.8 million.

The cumulative inflow has exceeded the 10 billion mark
Monday's record-breaking performance was not an isolated incident but the culmination of a strong recent trend.
The data shows,Since May this year, the Ethereum spot ETF has attracted more than $8 billion in net inflows. With the infusion of funds on Monday, cumulative net inflows into these products have reached $10.83 billion.
Strong capital flows have also provided strong support to the price of Ethereum. Data shows that the price of Ethereum has increased significantly by 45% in the past month. As of press time, its trading price was approximately $4,300, an increase of 1.78%.

Institutional confidence has increased and Ethereum is regarded as the “cornerstone”
Market analysts generally believe that the surge in capital inflows is a direct reflection of increased institutional confidence. Nick Ruck, Director of LVRG Research said:
Investors are increasingly recognizing the value of Ethereum as a store of value and foundational layer for decentralized finance and Web3 innovations. This demand reflects growing institutional confidence in Ethereum’s long-term potential.
Vincent Liu, chief information officer of Kronos Research, expressed a similar view. He believes that the capital inflow is supported by "continued regulatory favorable conditions and record traditional financial (TradFi) capital allocation". He noted that these factors are building deep liquidity pools that will “cement Ethereum as a cornerstone for mainstream adoption of cryptocurrencies.”
