U.S. spot Ethereum ETFs ended a seven-session run of net inflows on September 29, posting approximately $2.8 million in combined net redemptions. The reversal interrupted a streak that had brought roughly $850.6 million into Ether funds since September 18, according to Farside Investors’ daily Ethereum ETF flow dashboard. The modest withdrawal marked a change in daily direction rather than erasing the capital accumulated during the preceding sessions.
The September 29 total reflected offsetting movements across individual products. BlackRock’s ETHA recorded $8.9 million in net outflows and Fidelity’s FETH lost $6.7 million, while Grayscale’s lower-fee Ethereum product attracted $12.8 million. Those fund-level movements produced the $2.8 million aggregate outflow despite positive demand remaining in part of the category.
Ethereum’s $850M Run Comes to an End
The seven positive sessions began September 18 with $143.7 million of net inflows and accelerated to $270 million on September 21. Another $162.2 million entered on September 22, followed by $104.5 million, $66.1 million, $87 million and $17.1 million over the next five trading sessions. Taken together, the run delivered approximately $850.6 million of net creations before the September 29 reversal.
The sequence demonstrates how quickly ETF flows can change without necessarily establishing a broader allocation reversal. Ethereum products had previously experienced three consecutive outflow sessions from September 15 through September 17, including $224.1 million leaving on September 16, before flows turned strongly positive. A single negative session therefore provides a point-in-time reading of fund demand rather than evidence that the preceding allocation trend has permanently reversed. Earlier periods have similarly shown large differences between Bitcoin and Ethereum ETF demand.
BlackRock has continued expanding its Ethereum product lineup, including staking-linked exposure introduced earlier in 2026. That development followed substantial growth in its existing Ether products and reflects continued demand for relatively straightforward regulated crypto investment structures. Daily net flows, however, do not identify whether buyers or sellers are institutions, retail investors, advisers or other market participants, so they should not automatically be described as institutional accumulation or withdrawal.
Bitcoin ETFs Extend Their Own Inflow Streak
Bitcoin funds moved in the opposite direction on September 29, attracting $66.2 million in net inflows. BlackRock’s IBIT brought in $51.1 million and ARK 21Shares’ ARKB added $33.2 million, partially offset by $18.1 million of outflows from Bitwise’s BITB. The positive session extended the U.S. spot Bitcoin ETF category’s inflow streak to nine consecutive trading days.
That streak began September 17 and included particularly large sessions of $433 million on September 18, $999 million on September 21 and $714.7 million the following day. Across the nine sessions through September 29, Bitcoin ETFs accumulated approximately $3.08 billion in net inflows. The sequence follows earlier September volatility, including a $159.9 million Bitcoin ETF inflow dominated by BlackRock’s IBIT. Bitcoin’s current flow advantage is therefore substantial on this specific nine-session window, but it remains a historical snapshot rather than proof of future demand.
ETF flows also should not be mapped directly onto spot-market buying or price causality. Authorized participants can use hedging, inventory and derivatives while creating or redeeming ETF shares, making the relationship between ETF flows and immediate Bitcoin spot transactions more complex. The clearest interpretation of the September 29 data is narrower: Ethereum’s seven-day inflow streak ended while Bitcoin’s nine-session run remained intact.
The next measurable milestone is whether Ethereum funds return to positive territory in subsequent sessions or begin a sustained redemption cycle. Several consecutive outflow days would provide stronger evidence of changing ETF demand than the $2.8 million September 29 reversal alone, while continued Bitcoin inflows would extend an already substantial late-September accumulation period.
