Ethereum ETFs Have Seen 15 Straight Days of Green—Here’s Why

Ethereum ETFs have seen fifteen straight trading days of inflows—and it doesn’t show signs of slowing down.

Spot Ethereum exchange-traded funds, or ETFs, in the U.S. have notched their longest winning streak yet, pulling in a massive $837.5 million since May 16 and commanding renewed attention from institutional investors.

Spot ETH ETFs attracted $25.3 million in inflows on June 6 alone, capping off their third consecutive trading week in the green, according to Farside Investors data.

If the trend holds next week, net inflows since launch could cross $1 billion, a key psychological and market milestone for ETH bulls.

“ETH’s momentum appears driven by several converging factors: institutional ETF flows showing renewed interest in ETH products, growing anticipation around Ethereum’s roadmap upgrades,” Marcin Kazmierczak, Co-Founder and COO of Redstone, told Decrypt.

Optimism around the roadmap has been helped along by last month’s Pectra upgrade, said Luke Nolan, senior Ethereum research associate at CoinShares.

“I think a few factors are lining up in ETH’s favor. Firstly, we had the Pectra upgrade on the 7th of May which included a number of changes to the Ethereum protocol,” he told Decrypt. “None of them were that major, but they indicated stepping stones for further scaling, which has been a major bottleneck for a while on Ethereum. I also think sometimes a small narrative is enough to help drive positivity.”

Kazmierczak noted that the ETH/BTC market cap ratio rising above 0.14 signals a potential shift back to “risk-on” altcoins, a possible early “signal” of a broader altcoin season.

That conviction is showing up in the flows. Ethereum-related investment products led digital asset flows for the second straight week, attracting $296.4 million and pushing the 7-week total to $1.5 billion, according to the latest report from digital investment company CoinShares.

“This represents the strongest run of inflows since the U.S. election,” wrote James Butterfill, CoinShares Head of Research, adding the figure now represents 10.5% of all Ethereum assets under management.

Ethereum shedding its speculative rep

“ETH’s appeal is becoming more structural than speculative,” Tracy Jin, COO of MEXC Exchange, told Decrypt. “While Bitcoin is all over the news as a way to store money, Ethereum is becoming more popular as the base for the next generation of financial systems.

Jin noted how institutional buyers are starting to separate Ethereum from the noise.

“There’s a growing recognition that if blockchain is really here to stay—and it totally is—then ETH is the engine powering a lot of it,” she said.

In comparison, Bitcoin ETFs are flashing red.

U.S. spot Bitcoin ETFs saw $278 million in outflows on June 5, followed by $47.8 million more on June 6, finishing off a brutal week.

Leading the retreat was BlackRock’s iShares Bitcoin Trust (IBIT), which broke a 34-day inflow streak on May 30 by shedding $430.8 million in a single day, its worst outflow since February.

That single move helped drag total Bitcoin ETF outflows above $600 million for the day, ending what had been the strongest institutional run for IBIT yet, according to SoSo Value data.

Bitcoin ETFs continued to bleed last week, with a total of $131.6 million in outflows, according to Farside’s weekly data.

Fidelity’s FBTC led the outflows at $167.7 million, while GBTC and ARKB lost $40.6 million and $24.5 million, respectively. Only IBIT posted inflows, bringing in $81.1 million.



While Bitcoin ETFs struggle with outflows and macro headwinds, Ethereum’s steady inflows helped it edge up 6.4% over the past 30 days, just ahead of Bitcoin’s 4.1%, as per CoinGecko data.

“Unlike speculative tokens, Ethereum accrues real value through staking, transaction fees, and actual financial use,” Jin said, noting how “it’s becoming harder to ignore ETH’s role not just in crypto portfolios.”
