- U.S. spot Bitcoin ETFs drew a provisional $82.9 million in net inflows for the Sep. 28–Oct. 2 week, per Farside Investors.
- U.S. spot Ethereum ETFs saw roughly $118 million in net outflows over the same period.
- Bitcoin’s weekly intake collapsed from $2.39 billion the prior week — a drop of more than 96%.
- Bitcoin traded near $84,640 and Ethereum near $2,679, both marginally higher on the day.
What stands out is not the direction of Bitcoin flows but their magnitude. The $82.9 million weekly haul is a fraction of the $2.39 billion that flowed into the same cohort in the preceding week — a decline of more than 96%. That kind of swing is typical when a single outsized allocation or a burst of momentum-driven buying flatters one week’s print and leaves the next looking anaemic by comparison. It also suggests that the marginal buyer who showed up earlier in the period has stepped back, leaving steadier, smaller-ticket demand to carry the tape.
Bitcoin Holds, Ethereum Retreats
Price action has been similarly restrained. Bitcoin changed hands around $84,640, up 0.17% on the day, while Ethereum traded near $2,679, higher by 0.42%. Neither move is large enough to explain the flow gap on its own, which points to positioning rather than performance as the driver. When investors are trimming risk, they tend to consolidate into the deepest, most liquid instrument in a category — and in crypto ETFs, that is unambiguously the Bitcoin complex. Ethereum funds, by contrast, have struggled to build a durable base of sticky inflows since launch, and weeks like this one reinforce that pattern.
The outflow figure for Ethereum ETFs is meaningful in relative terms. A $118 million net redemption against a fund category whose aggregate assets remain far smaller than Bitcoin’s represents a proportionally heavier hit. It also arrives without an obvious single catalyst — no protocol-level shock, no regulatory headline — which makes it look more like routine de-risking than a reaction to news. That distinction matters for how the next few weeks are read: mechanical rebalancing fades, whereas event-driven selling tends to persist.
What the Split Signals for Allocators
For advisors and institutions using ETFs as their crypto wrapper, the week’s data offers a reminder that “crypto exposure” is not a monolith. Bitcoin and Ethereum funds now behave like separate asset classes with distinct flow profiles, liquidity characteristics, and holder bases. A portfolio that treats them interchangeably is exposed to a dispersion it may not have underwritten. The Bitcoin vehicle has become the default expression of the trade; the Ethereum vehicle increasingly functions as a satellite position that gets funded last and cut first.
It is worth keeping the numbers in proportion. Weekly ETF flow data is provisional, subject to revision, and prone to distortion from a handful of large creations or redemptions. A single week of $82.9 million in and $118 million out does not establish a trend. But the direction of travel — Bitcoin retaining modest support while Ethereum gives ground — is consistent with the broader pattern of the past several months. If that persists, expect continued concentration in the largest fund, thinner liquidity in the second-largest, and a wider gap between the two than many allocators assumed when both categories launched.
