Single-sourceKUALA LUMPUR, 26 SEPTEMBER 2026 —
US crypto exchange‑traded funds pulled in more than $3 billion of net inflows from Monday to Thursday, with Bitcoin spot products accounting for roughly $2.25 billion and the remaining four assets – Ethereum, Solana, XRP and Zcash – together attracting about $793 million, SoSoValue data showed.
Market Impact
The surge marks the strongest daily inflow for Bitcoin spot ETFs in 2026 and the largest single‑day intake since the $1.2 billion influx on 6 October 2025, signalling renewed investor appetite that has spread beyond the flagship cryptocurrency into a broader range of digital‑asset products.
Bitcoin spot ETFs opened the week with a $999 million net addition, the biggest daily flow of the year and the largest since October 2025. The inflow represented roughly 11,530 BTC, the biggest single‑day intake in coin terms since November 2024. Positive net flows continued for a fourth straight session on Thursday, when the funds added $190.65 million, extending the four‑day haul to $2.25 billion.
Bitfinex said the demand “re‑emerged alongside corporate treasury buying, creating simultaneous sources of spot demand for the first time this year.”
The inflow wave unfolded as Bitcoin recovered from a dip below $58,000 in early June. By 13 July, US spot Bitcoin ETFs had accumulated a $5.69 billion year‑to‑date deficit, but the deficit narrowed as the cryptocurrency rallied toward the mid‑$80,000 range. Despite the fresh capital, Bitcoin has struggled to sustain momentum above $85,000 since Tuesday, after reaching a high of $87,392 on 21 September, according to Bitfinex.
The exchange identified a concentration of recent buying between $85,000 and $86,500 and estimated the aggregate ETF investor break‑even level near $86,000, placing the latest buyers close to the centre of Bitcoin’s current trading range.
SoSoValue’s 24 September snapshot recorded the 12 US Bitcoin spot ETFs holding $108.92 billion in net assets, with cumulative net inflows of $57.43 billion. Ethereum spot ETFs were the clearest beneficiary among non‑Bitcoin products, drawing $602.94 million over the same four‑day period – more than three‑quarters of all capital that moved into alt‑coin ETFs. The daily breakdown was $269.98 million on Monday, $162.31 million on Tuesday, $104.63 million on Wednesday and $66.01 million on Thursday.
Bitfinex said Monday’s $270 million inflow was the largest daily total for Ethereum ETFs since 7 October 2025. By 24 September, 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.
Solana‑focused products attracted $101.55 million from Monday through Thursday, including $32.81 million on Thursday, lifting their cumulative total to $1.52 billion with net assets of $1.81 billion. XRP ETFs added $52.95 million over the same period, with inflows of $20.02 million on Tuesday, $18.04 million on Wednesday and $14.89 million on Thursday, taking cumulative inflows to $1.77 billion against about $1.70 billion in net assets.
Zcash products drew $35.17 million this week; the single tracked fund showed $306.12 million in cumulative net inflows and about $1 billion in net assets, marking a rapid build‑up for a product that began trading earlier this month.
Combined, Solana, XRP and Zcash attracted roughly $189.7 million, and together with Ethereum, non‑Bitcoin products brought in about $792.6 million – roughly 26 % of total inflows across the five assets. Bitcoin and Ethereum together therefore absorbed about $2.85 billion, or almost 94 % of the week’s net inflows.
The broader crypto market posted stronger performance alongside the ETF buying. Bitfinex reported that all 35 non‑Bitcoin pairs it tracked advanced between 18 and 22 September, with a median gain of 12 %, compared with Bitcoin’s 6.6 % rise. Its alt‑coin‑season indicator turned positive on 22 September for the first time since January, underscoring the widening rally beyond the flagship coin.
The influx of capital into US spot crypto ETFs arrives as regional investors watch the US market for signals on digital‑asset allocation. Malaysia’s Securities Commission has previously cautioned retail participants about the volatility of crypto assets, while regional fund managers have begun to explore exposure through regulated products.
The sizable Bitcoin inflows, coupled with the expanding footprint of Ethereum and other alt‑coin ETFs, suggest that institutional and corporate treasury participants are increasingly comfortable with regulated spot exposure, a trend that could shape future product launches in Southeast Asia.
Bitfinex’s observation that corporate treasury buying is now a concurrent source of spot demand points to a diversification of the investor base. If corporate participation continues to grow, the demand dynamics that have driven the recent $3 billion inflow may persist, providing a steadier foundation for the nascent US spot ETF market and potentially encouraging similar offerings in neighbouring jurisdictions.
The latest data leaves the market at a crossroads: Bitcoin’s price remains clustered around the $86,000 break‑even estimate for ETF investors, while Ethereum and the smaller‑cap products enjoy fresh inflows that could sustain their upward trajectories. Continued buying pressure will be essential to push Bitcoin beyond its current range and to cement the broader rally that has lifted the majority of crypto assets this week.
