US Crypto ETFs Pull $3B as Demand Spreads Beyond Bitcoin

Bitcoin's Strongest Day of 2026

Bitcoin spot ETFs began the week with a positive flow of $999 million, the strongest single-day inflow of 2026. That purchase represented roughly 11,530 BTC—the largest single-day intake in coin terms since November 2024. The funds added $190.65 million on Thursday, extending their four-day haul to $2.25 billion.

The timing matters. US spot Bitcoin ETFs had accumulated a $5.69 billion year-to-date deficit by July 13 before demand reversed. This week's inflows signal a sharp pivot—one that coincides with Bitcoin's recovery from below $58,000 in early June toward the mid-$80,000 range.

Ethereum and Altcoins Gain Traction

US spot Ethereum ETFs attracted $602.94 million from Monday through Thursday. The breakdown shows momentum building: $269.98 million Monday, $162.31 million Tuesday, $104.63 million Wednesday, and $66.01 million Thursday. Bitfinex noted that Monday's $270 million inflow was Ethereum ETFs' largest daily total since October 7, 2025.

Bitcoin and Ethereum together absorbed about $2.85 billion, or almost 94% of the five assets' combined inflows this week. The remaining $190 million split among Solana ($101.55 million), XRP ($52.95 million), and Zcash ($35.17 million). Zcash products drew $35.17 million this week, a milestone for a product that only began trading earlier in the month.

Dual Demand Engines

"Bitfinex said this ETF demand had re-emerged alongside corporate treasury buying, creating simultaneous sources of spot demand for the first time this year."

Price action reflects the tension. Bitcoin has struggled to extend its rally above $85,000 since Tuesday after reaching as high as $87,392 on Sept. 21. 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 clustering suggests institutional buyers are testing support—and waiting for confirmation before pushing higher.

The 12 US Bitcoin spot ETFs held $108.92 billion in net assets as of September 24, with cumulative net inflows of $57.43 billion. Ethereum ETFs, meanwhile, had accumulated $13.85 billion in cumulative net inflows with combined net assets of $17.70 billion. The growth underscores a structural shift: spot ETFs are becoming the primary on-ramp for institutional capital into digital assets.
