US-listed spot exchange-traded funds recorded more than $3 billion of net new money from Monday through Thursday, according to data compiled by SoSoValue. Bitcoin-focused products remained the primary magnet, absorbing $2.25 billion, while the remaining four tracked assets together attracted close to $800 million.
Bitcoin ETFs see strongest daily intake of the year
The Bitcoin ETF segment posted a $999 million inflow on Monday, the biggest single-day addition for any fund in 2026 and the most sizable since early October 2025. The purchase volume translates to roughly 11,530 BTC, marking the highest daily acquisition in coin terms since November 2024. The positive flow continued for a fourth straight session, with Thursday’s addition of $190.65 million extending the four-day total to $2.25 billion.
Ethereum emerges as the main beneficiary among altcoins
Ethereum-linked ETFs captured $602.94 million over the same period, representing more than 75% of all capital that moved into non-Bitcoin products. Daily contributions were $269.98 million on Monday, $162.31 million on Tuesday, $104.63 million on Wednesday and $66.01 million on Thursday. Monday’s influx was the largest Ethereum ETF intake since early October 2025.
Smaller crypto ETFs add modest but growing interest
Solana-related funds accumulated $101.55 million, with a $32.81 million injection on Thursday. XRP ETFs gathered $52.95 million, spread across three days, while Zcash-focused products saw $35.17 million in new money. Collectively, these three assets contributed about $190 million to the week’s total inflows.
Asset bases and cumulative inflows
By the end of the week, the twelve US Bitcoin spot ETFs held $108.92 billion in net assets and had received $57.43 billion in cumulative net inflows since inception. The eleven Ethereum ETFs reported $17.70 billion in assets, with total inflows reaching $13.85 billion. Solana, XRP and Zcash funds now sit at $1.81 billion, $1.70 billion and $1 billion in net assets respectively, each reflecting steady accumulation since they launched.
Market context and price dynamics
The ETF surge coincided with Bitcoin’s rebound from sub-$58,000 levels in early June to a trading range centered around $86,000. Analysts estimate the break-even point for ETF investors near $86,000, a level that aligns with the current concentration of buying activity. Despite the inflows, Bitcoin has struggled to sustain momentum above $85,000 after briefly touching $87,392 on September 21.
Altcoin performance gains traction
During the same week, all 35 non-Bitcoin pairs tracked by Bitfinex posted median gains of 12%, outperforming Bitcoin’s 6.6% rise. The altcoin-season indicator turned positive for the first time since January, suggesting broader market enthusiasm beyond the flagship cryptocurrency.
Why it matters
The latest wave of inflows underscores renewed investor confidence in regulated crypto products, especially as corporate treasury demand re-emerges alongside retail interest. Bitcoin’s dominant share of the flows highlights its continued status as the preferred store of value, yet the significant capital directed toward Ethereum and other altcoins signals diversification within the ETF space. Sustained demand will be crucial for translating these inflows into higher price levels, particularly for Bitcoin, which now hovers near the estimated break-even threshold for ETF participants.
