U.S. spot Ethereum ETFs posted their strongest single day in 10 months on Thursday, taking in $225.8 million in net inflows and extending a buying streak that has now run for nine consecutive sessions. The funds, which the SEC approved in mid-2024 after clearing the way for spot Bitcoin ETFs earlier that year, have become one of the main bridges between traditional finance and Ethereum, letting brokerage and advisory clients gain ETH exposure without holding the asset directly.

The nine trading days beginning August 17 have delivered a combined $1.42 billion in net inflows, according to Farside Investors data. The last day of net outflows was August 11, with August 14 the only session since to register no net flow in either direction. Thursday's total was the largest since October 28, 2025.

BlackRock has driven most of the buying. Its ETHA fund took in $1.02 billion over the nine sessions, or 72% of the category's total, and has not recorded a single day without net buying. Blockchain analytics firm Arkham flagged the streak on Thursday, counting $889.8 million across the first eight days—a figure that matches Farside's tally exactly.

Fidelity's FETH has been the second-largest taker, recording its best day of the run on Thursday at $56.2 million. BlackRock's staked Ethereum product, ETHB, added $20.7 million the same day.

The gap with Bitcoin has narrowed to almost nothing. U.S. spot Bitcoin ETFs took in $242.3 million on Thursday—just $16.5 million more than their Ethereum counterparts, according to Farside data. On August 17, the first day of both runs, the Ethereum funds took a tenth of what Bitcoin's did.

Ethereum traded around $2,477 on Friday, down 0.5% over the past 24 hours but up roughly 5% on the week, according to CoinGecko data.

What is pulling the money in

The buying is coming from outside crypto, according to Max Shannon, senior research associate at Bitwise Europe. He put this week's take at $713.6 million, matching Farside's count, and said the flows had "likely been driven by the marked rise in Cross Asset Risk Appetite," the firm's measure of risk appetite in traditional markets. In other words, the same appetite for risk that has lifted broader markets appears to be spilling into crypto via the ETF channel.

Ethereum has still lagged Bitcoin and the larger altcoins over the same stretch. Shannon called that "warranted given its strength since the broader crypto rally started on the 19 August, and especially over the past couple of months." Capital has since rotated into "higher-beta blue-chip names such as ZEC, XRP, SOL and HYPE," which have outperformed, he said, with Bitwise's dispersion index rising this week and "suggesting the market is being driven by a broader set of narratives."

Ethereum is currently hovering around its 200-week moving average for the first time since it broke support in late January, Shannon noted, calling it an "important level to hold" that could shape short-to-medium-term momentum. He added that investors picked up roughly 1.1 million ETH around that level, a block that "could act as temporary resistance if those holders sell into strength." Whether ETF inflows continue at this pace—and whether spot trading volume revives—will be the key signals to watch in the sessions ahead.

The flows may not be enough on their own. "Given flows are reflexive and momentum-based, a pick-up in spot volume is needed for the market to sustain its footing," Shannon said, noting that spot volume has softened to its 16th percentile year-on-year since the rally began on August 19.
