US spot crypto exchange-traded funds tracking Bitcoin, Ethereum, Solana, XRP, and Zcash recorded $3.04 billion in combined net inflows from Monday through Thursday of this week, according to data from SoSoValue. Bitcoin ETFs dominated the period with $2.25 billion in inflows, while Ethereum attracted $603 million.
Monday proved the strongest day for Bitcoin, with $999 million in inflows and 11,530 BTC in single-day intake. That Monday inflow marked the strongest daily Bitcoin ETF inflow of 2026 and the largest since the funds drew about $1.2 billion on Oct. 6, 2025. Thursday added another $190.65 million to Bitcoin ETF flows.
Ethereum ETF inflows spread more evenly across the four-day window. Monday saw $269.98 million, Tuesday $162.31 million, Wednesday $104.63 million, and Thursday $66.01 million. The combined $602.94 million in Ethereum inflows represented the second-largest asset class in the period, though it fell short of the $270 million single-day record set on Oct. 7, 2025.
Bitcoin and Ethereum together accounted for $2.85 billion of the four-day total, or 94 percent of inflows across the five assets. The remaining assets drew $792.6 million combined. Solana ETFs pulled in $101.55 million, with $32.81 million arriving Thursday. XRP ETFs attracted $52.95 million across the period. Zcash ETFs recorded $35.17 million in inflows this week.
The inflow period coincided with broader strength in smaller-cap digital assets. Bitfinex’s altcoin-season indicator turned positive on Sept. 22 for the first time since January. Across 35 non-Bitcoin trading pairs, the median gain from Sept. 18 through Sept. 22 reached 12 percent, compared to a 6.6 percent rise in Bitcoin over the same span.
Bitcoin reached $87,392 on Sept. 21. The asset faced resistance near $85,000 and at an upper concentration of buying interest around $86,500. Estimates placed the aggregate break-even level for ETF investors at $86,000.
The week’s inflows marked a reversal from earlier patterns. Through July 13, US Bitcoin spot ETFs had accumulated a year-to-date deficit of $5.69 billion. Bitcoin has since recovered from below $58,000 in early June. As of Sept. 24, the 12 US Bitcoin spot ETFs held $108.92 billion in net assets, built from $57.43 billion in cumulative net inflows. The 11 Ethereum ETFs held $17.70 billion in combined net assets, reflecting $13.85 billion in cumulative inflows. Solana ETFs held $1.81 billion in net assets on $1.52 billion in cumulative inflows, while XRP ETFs held $1.70 billion in net assets on $1.77 billion cumulative. Zcash ETFs held $1 billion in net assets on $306.12 million in cumulative inflows.
