The latest weekly fund flow data show that Bitcoin spot ETFs recorded a combined net inflow of $241 million last week, marking a third consecutive week of net inflows, while Ethereum spot ETFs recorded a combined net outflow of $138 million during the same statistical period. Fund flows for the two types of crypto spot ETF products showed a clear divergence, with Bitcoin spot ETFs continuing to attract returning capital while Ethereum spot ETFs faced weekly net outflow pressure. As an important channel connecting traditional financial markets and crypto assets, changes in spot ETF fund flows continue to draw market attention.
From the perspective of the institutions and products involved, BlackRock's IBIT saw a weekly inflow of $450 million, making it the main contributor to the overall net inflow into Bitcoin spot ETFs; Fidelity's FETH saw a weekly outflow of $74.0624 million, the largest outflow among Ethereum spot ETFs. BlackRock's IBIT and Fidelity's FETH are both leading products in the spot ETF market, and their fund changes have a significant impact on the overall data for their respective asset classes. The market typically watches fund changes in leading products because they often more directly reflect institutional investors' short-term allocation preferences.
Within Bitcoin spot ETFs, there is a clear gap between the combined net inflow of $241 million and BlackRock's IBIT weekly inflow of $450 million. This data relationship indicates that, apart from IBIT, other Bitcoin spot ETF products as a whole showed net outflows in the latest statistical week. Therefore, the consecutive net inflows into Bitcoin spot ETFs are not a broad-based recovery in capital; they are mainly driven by large inflows into a single product, BlackRock's IBIT. Changes in BlackRock's IBIT have become an important window for observing institutional demand.
Within Ethereum spot ETFs, Fidelity's FETH saw a weekly outflow of $74.0624 million, accounting for more than half of the combined net outflow of $138 million from Ethereum spot ETFs. This shows that although the outflow pressure on Ethereum spot ETFs is concentrated in Fidelity's FETH, the product alone did not cause the overall net outflow; other Ethereum spot ETF products also contributed to the remaining outflows. Fund outflows mean that redemptions exceeded subscriptions during the week, a change that is usually viewed by the market as one of the short-term capital flow signals.
Observing the weekly data for Bitcoin spot ETFs and Ethereum spot ETFs side by side, the current crypto spot ETF market shows a dual divergence: first, divergence at the asset level, with Bitcoin spot ETFs seeing net inflows for three consecutive weeks while Ethereum spot ETFs saw a single-week net outflow; second, divergence at the product level, with BlackRock's IBIT and Fidelity's FETH becoming the leading products in their respective flow directions within the same asset class. This structural feature indicates that institutional capital allocation in crypto spot ETFs is not synchronized across the board but instead shows clear asset preferences and product selection. For market observers, fund flows in Bitcoin spot ETFs and Ethereum spot ETFs provide two independent dimensions for observation.
From the perspective of capital flow signals, three consecutive weeks of net inflows into Bitcoin spot ETFs show that the capital return has a phased continuation characteristic rather than being a single-week fluctuation; the single-week net outflow from Ethereum spot ETFs shows that its short-term capital flow still faces pressure. From a longer perspective, spot ETF subscription and redemption data often more directly reflect institutional capital allocation preferences. Compared with short-term price fluctuations, weekly fund flow data provide a relatively stable observation dimension. However, because this data covers only one statistical week and the original source did not disclose the specific time period, its signal significance still needs to be understood in conjunction with changes in data over consecutive weeks.
The above data come from PANews reports on spot ETF fund flows. It should be noted that the original report used only "last week" as the time description and did not specify the exact start and end dates of the statistical period. Therefore, when citing the relevant data, the market can cross-check with subsequent data disclosed by product issuers or trading platforms to enhance the accuracy and verifiability of the data on the time dimension.
Looking ahead, whether net inflows into Bitcoin spot ETFs can continue and whether BlackRock's IBIT will continue to dominate the overall data will be key to observing Bitcoin's funding situation. Whether Ethereum spot ETFs can reverse the single-week net outflow and how fund flows change at leading products such as Fidelity's FETH also deserve continued tracking. The market will continue to watch changes in subscription and redemption data for both types of spot ETFs and, on that basis, assess institutional capital's phased allocation preferences for crypto assets.
