Institutional money is pouring into Ether this week. U.S. spot Ethereum ETFs drew roughly $2.39 billion in net inflows over the six trading days through July 25, 2025, according to Farside Investors data.
By comparison, spot Bitcoin ETFs took in only about $827 million in the same span. In fact, Ether funds outpaced Bitcoin on each of those six days, a rare flip from the usual order.
These figures underline a sudden surge of institutional demand shifting toward Ethereum, even as Bitcoin remains the market leader.
BlackRock’s ETHA Leads Ethereum ETFs Charge
The lion’s share of the new inflows went to BlackRock’s iShares Ethereum Trust (ETHA). Over the six-day period, ETHA alone attracted about $1.79 billion, roughly 75% of all Ether ETF inflows.
That means ETHA’s AUM jumped past $10 billion in just 251 trading days – making it one of the fastest ETFs ever to hit that milestone.
BlackRock’s fund has dominated the market since launch, and this week’s flows underscore its popularity.
Other Ethereum products also saw big gains. Fidelity’s Ethereum Fund (FETH) set a new record last Thursday by taking in $210 million.
This marked a 4% increase over FETH’s previous best single-day inflow ($202 million in Dec. 2024). Grayscale’s smaller ETH funds and others likewise saw heavy buying, though on a lesser scale.
The net effect: spot ETH funds are gobbling up new money at a pace that Bitcoin funds can’t match right now.
Corporate Buying and a Tightening Supply
Demand for ETH isn’t coming from ETFs alone. Corporate treasuries are stocking up too. BitMine Immersion Technologies, a crypto mining firm, bought roughly $2 billion worth of ETH in just 16 days, making it the largest corporate holder of Ether.
Strategic Ether Reserves data show that all companies now hold about 2.31 million ETH, or 1.91% of Ether’s circulating supply. This concentrated buying is expected to tighten available supply.
Galaxy Digital’s CEO Michael Novogratz has highlighted these trends, forecasting that ongoing accumulation could push Ether toward $4,000.
He noted that purchases by BitMine and by SharpLink Gaming (a blockchain game studio) may create a “supply shock” that would lift prices.
Indeed, Ethereum’s price is already up about 9% on the week. Analysts caution that while demand is strong, any unexpected regulatory or market issues could still slow ETH’s rise.
Bitcoin ETF Flows Stall
Bitcoin ETFs, by contrast, have hit a speed bump. U.S. spot Bitcoin funds logged a net outflow of about $131 million on Monday (July 22), ending a 12-day run of positive inflows.
That 12-day streak had accumulated roughly $6.6 billion into Bitcoin products, so the sudden outflow was notable. The pause suggests some investors are shifting capital out of Bitcoin and into Ethereum and other assets.
Research firm Swissblock commented on the trend: “ETH is rotating into leadership as the next leg of the cycle unfolds.”
In other words, Ethereum may be taking the lead role for now, while Bitcoin steps back. If the pattern continues, industry observers say Bitcoin could be “second fiddle” in the near term.
It’s worth noting that overall market conditions were choppy – a broad crypto sell-off on July 23-24 saw BTC dip toward $115K and ETH slip under $3,600. That volatility likely influenced ETF flows as well.
This week’s data highlight a notable pivot in institutional sentiment. Ethereum’s ETFs are now attracting the bulk of new crypto capital, at least in the short term.
The upshot for investors: Ether, long the “workhorse” blockchain for DeFi and smart contracts, is being treated more like an institutional asset, not just an altcoin.
Traditional investors are reportedly citing Ethereum’s upcoming protocol upgrades and growing real-world usage as key reasons to allocate there.
All told, the facts speak for themselves. Nearly $2.4B flowed into ETH ETFs in six days vs. $0.827B for BTC ETFs. BlackRock’s ETHA dominated with $1.79B.
Corporate buyers now hoard 1.91% of all ETH. And industry titans like Novogratz publicly set $4K targets based on these trends.
Taken together, the data signal that for the moment, institutions are marching to Ethereum’s beat.
