The early-week surge lifted US spot bitcoin ETF inflows to a 2026 high and flipped YTD flows positive; Ether and XRP ETFs also saw net buys, SoSoValue data showed.
US spot bitcoin exchange-traded funds logged $2.39 billion of net inflows this week, their strongest weekly haul of 2026 and the biggest since the week ending Oct. 10, 2025, when inflows reached $2.71 billion, according to SoSoValue. The burst flipped year-to-date flows to about $926 million.
The print topped August’s 2026 high of $1.92 billion by roughly 24.5% — a calculation from SoSoValue’s figures. Friday added $134.5 million after Monday’s near–$1 billion surge, with daily pace easing later in the week as bitcoin pulled back from above $87,100. Bitcoin traded around $83,116 at publication, down 1.6% on the day but up 1.7% week-on-week, CoinGecko showed.
ETF flow mechanics matter: net creations require market makers to source the underlying asset. The move from a roughly $5.55 billion year-to-date deficit in early July to about $926 million in positive territory implies around $6.48 billion of net buying via the ETF channel since then — a calculation using SoSoValue’s levels. That swing suggests demand has rebuilt across recent weeks rather than arriving in a single session.
Across other US spot crypto funds, ether ETFs attracted about $690 million in net inflows last week, reversing roughly $140 million of outflows the prior week, while XRP ETFs added about $76 million, SoSoValue reported. Broader sentiment improved: the Crypto Fear & Greed Index rose to 74 from 70 a week earlier, according to Alternative.me.
What to watch next
Whether weekly strength persists beyond an early-week spike; how flows distribute across issuers; and if ether’s reversal holds in subsequent sessions. Daily ETF prints alongside price action will show if the bid is broad and sustained or momentum-led.

🧠 HafidWatch Take
Sustained inflows spaced across several sessions rather than concentrated surges are more likely to influence bitcoin’s price beyond short-term momentum. However, if large ETF creations continue primarily on days when bitcoin’s price declines or remains flat, it could indicate parallel demand that doesn’t immediately translate into upward price pressure. Monitoring the relationship between inflow timing and price movements will be crucial to understanding how these flows affect market dynamics going forward.
