Ethereum ETF Records 3-Day Inflow Streak

According to the Farside Ethereum ETF inflows stats, the 9 ETFs cumulatively gained a total net inflow of $64.889M on May 20, which is among the largest single-day inflows recorded. Interestingly, this made the three 3-Day streak, as before this, they gained $13.7M and $22M on May 19 and May 16, 2025, revealing high institutional demand.

In yesterday’s milestone, the top contributor is BlackRock’s ETHA, which had its largest daily inflow of $45M. Fidelity’s FETH is next in line, receiving $19.8M, respectively. As a result, the total ETH ETF AUM is at $8.7B, and the cumulative Net inflow is $2.6B. Additionally, the Ethereum price surpassed $2.6k mark momentarily.


Although the milestone is significant, it is nowhere near the Bitcoin ETF’s normal inflow, let alone the peak.

Bitcoin Vs Ethereum ETF: Why Bitcoin is Dominating the Inflows?

Bitcoin and Ethereum are the biggest cryptocurrencies in the market and have been competing with each other ever since. The same competition is also persistent in the ETF inflows, and Bitcoin leads the race by multiple folds.

On the day the Ethereum ETF received its biggest single-day inflow, BTC hit $329M, almost 5x more. In this, BlackRock’s IBIT took the lead with $287 million in inflows. Some experts speculate that BlackRock will overtake Satoshi Nakamoto in terms of BTC holdings, as its netflow is of $3.63B.


Interestingly, there are many reasons behind this difference in inflows between the two. First, Bitcoin is seen as digital gold and has the first-ever digital asset spot ETF approval from the SEC. Its higher adoption and visibility, including the U.S. Strategic Bitcoin Reserve plans, give it the upper hand.

Additionally, its market size and liquidity are higher than ETH’s. Besides, institutional involvement, like MicroStrategy BTC buying, and other push investors towards this crypto and its exchange-traded fund, hence the high inflows.

Interestingly, this has been happening from day one and is likely to continue unless Ethereum witnesses significant updates and demands. The SEC decision on Bitwise’s ETH ETF with staking and other updates could influence the ETFs’ collective inflows.
