US spot Bitcoin exchange-traded funds (ETFs) netted $83 million in weekly inflows despite volatile daily trading, while spot Ethereum ETFs ended the week in the red with $114 million in total net outflows.
Key Takeaways
- Spot Bitcoin ETFs recorded $83 million in net positive flows, cooling down after a record $2.39 billion week.
- Spot Ethereum ETFs suffered $114 million in net outflows, lowering cumulative net inflows to $13.80 billion.
- Wednesday redemptions saw $148.69 million exit Bitcoin products despite cooler-than-expected PCE inflation data.
Bitcoin ETF Inflows Cool Down Following Record Week
The spot Bitcoin ETFs continued their overall positive streak, securing $83 million in net positive inflows for the week. This modest performance follows an explosive prior week where funds pulled in $2.39 billion—their strongest five-day performance in nearly a year. That surge helped reverse a year-to-date figure that saw massive redemptions earlier in 2026, including $2.43 billion leaving in May and a net withdrawal of $4.5 billion in June.
The weekly momentum started on September 28 with $31.07 million in net inflows, followed by $66.19 million on Tuesday. However, institutional investors pulled $148.69 million out of the vehicles on Wednesday, a surprise movement given that PCE inflation data released that day came in lower than projected. Momentum bounced back on Thursday with $102.67 million in net entry according to SoSoValue, while FarSide data confirmed $31.7 million in inflows on Friday. Over the last four trading weeks, flows have fluctuated wildly, moving from a $462.73 million outflow week to a modest $6.21 million inflow, followed by the $2.39 billion surge and this week's $83 million total, as traders track Bitcoin trading dynamics.
Ethereum Funds Face Continued Outflows
Spot Ethereum ETFs failed to sustain early week positivity. The products opened with $17.10 million in net inflows on Monday, but withdrawals took firm control for the remainder of the business week. Outflows hit $2.81 million on Tuesday, $59.58 million on Wednesday, $55.37 million on Thursday, and $17.3 million on Friday.
In total, Ethereum funds suffered $114 million in weekly net outflows according to SoSoValue. This marks the second negative week out of the last three for ETH products, though the single positive week in that span registered significant inflows of nearly $690 million. Consequently, cumulative net inflows for spot Ethereum ETFs slipped from their recent local peak of $13.94 billion down to $13.80 billion.
Why It Matters
The divergence between Bitcoin and Ethereum ETF flows illustrates differing levels of institutional confidence across major digital assets. While Bitcoin products maintain positive year-to-date momentum, Ethereum funds remain vulnerable to rapid sentiment shifts and profit-taking. Market participants will be watching whether upcoming macroeconomic figures can restore broader demand across both ETF sectors.
