US crypto exchange-traded funds have pulled in more than $3 billion this week as fresh demand spread beyond Bitcoin into Ethereum and altcoin products.
Spot ETFs tracking Bitcoin, Ethereum, Solana, XRP and Zcash recorded about $3.04 billion of combined net inflows from Monday through Thursday, according to SoSoValue data. Bitcoin remained the dominant destination with $2.25 billion, while the other four assets attracted nearly $793 million.
Bitcoin spot ETFs began this week with a positive flow of $999 million, which was the strongest daily inflow of 2026 and the largest since the funds drew about $1.2 billion on Oct. 6, 2025. These purchases represented roughly 11,530 BTC, the biggest single-day intake in coin terms since November 2024.
The inflows stayed positive for a fourth consecutive session on Thursday, as the funds added $190.65 million, extending their four-day haul to $2.25 billion.
Bitfinex said this ETF demand had re-emerged alongside corporate treasury buying, creating simultaneous sources of spot demand for the first time this year.
The flow reversal has unfolded alongside Bitcoin’s recovery from below $58,000 in early June. US spot Bitcoin ETFs had accumulated a $5.69 billion year-to-date deficit by July 13, before demand swung back as the cryptocurrency recovered toward the mid-$80,000 range.
Yet the latest inflows have not produced another immediate leg higher. Bitcoin has struggled to extend its rally above $85,000 since Tuesday after reaching as high as $87,392 on Sept. 21, according to Bitfinex. The firm identified a large concentration of recent buying between $85,000 and $86,500, with its estimate of the aggregate ETF investor break-even level sitting near $86,000.
That puts the latest ETF buyers close to the center of Bitcoin’s current trading range and makes continued demand increasingly important if the rally is to hold.
SoSoValue’s Sept. 24 snapshot showed the 12 US Bitcoin spot ETFs holding $108.92 billion in net assets, with cumulative net inflows of $57.43 billion.
Ethereum takes the bulk of flows outside Bitcoin
Ethereum has been the clearest beneficiary of the widening ETF bid.
US spot ETH ETFs attracted $602.94 million from Monday through Thursday, according to SoSoValue, accounting for more than three-quarters of all the capital that moved into non-Bitcoin products.
The funds took in $269.98 million on Monday, followed by $162.31 million Tuesday, $104.63 million Wednesday and another $66.01 million Thursday. That gave Ethereum four consecutive positive sessions alongside Bitcoin.
Bitfinex said Monday’s $270 million inflow was Ethereum ETFs’ largest daily total since Oct. 7, 2025. The demand arrived even as ETH’s price performance lagged several smaller cryptocurrencies during the broader market rebound.
By Sept. 24, cumulative net inflows into the 11 Ethereum ETFs tracked by SoSoValue had reached $13.85 billion, while their combined net assets stood at $17.70 billion.
Bitcoin and Ethereum together therefore absorbed about $2.85 billion, or almost 94% of the five assets’ combined inflows this week.
Solana, XRP and Zcash draw nearly $190 million
Flows into smaller crypto ETFs were modest compared with Bitcoin and Ethereum, but they broadened the week’s buying across the market.
Solana products attracted $101.55 million from Monday through Thursday, according to SoSoValue, including $32.81 million on Thursday. The inflows lifted their cumulative total to $1.52 billion, with net assets of $1.81 billion.
XRP ETFs added $52.95 million over the same period. Flows resumed Tuesday with $20.02 million, followed by $18.04 million Wednesday and $14.89 million Thursday, taking cumulative inflows to $1.77 billion against about $1.70 billion in net assets.
Zcash products drew another $35.17 million this week, with SoSoValue showing the single tracked fund at $306.12 million in cumulative net inflows and about $1 billion in net assets. The milestone marks a rapid asset build-up for a product that only began trading earlier this month.
Combined, Solana, XRP and Zcash attracted about $189.7 million this week. Including Ethereum, non-Bitcoin products brought in roughly $792.6 million, or about 26% of total inflows across the five assets.
The wider ETF buying has come alongside stronger performance across the rest of the crypto market. Bitfinex said all 35 non-Bitcoin pairs it tracked advanced between Sept. 18 and Sept. 22, with a median gain of 12%, compared with Bitcoin’s 6.6% rise. Its altcoin-season indicator turned positive on Sept. 22 for the first time since January.
