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.
