Ethereum ETF Flow Tracker: Why Weekly Outflows Topped $320M, Surpassing Bitcoin

 

Summing the daily figures published by Farside Investors, US spot Ethereum ETFs recorded net outflows of roughly $320.1 million across the full trading week of October 12 to 16, against roughly $228.4 million for spot Bitcoin ETFs over the same days. A product line holding about one seventh the assets lost more money in absolute terms.

 

Two points on methodology come first. This is the complete week through October 16 and should not be described as October 19 flow data, since Farside updates with a one-day lag and the first print of a new week arrives after Monday's close. Separately, net flow measures creations and redemptions of fund shares, which is not the same as the change in a fund's net assets, because the latter also moves with price. Conflating the two is the most common error in reading this data.

 

Scale sharpens the conclusion. Per SoSoValue data relayed by ChainCatcher, spot Ethereum ETFs held $14.946 billion in net assets as of October 16, equal to 5.07% of ether's market capitalisation, while spot Bitcoin ETFs held $104.290 billion, or 6.35% of bitcoin's. On that basis last week's outflow equalled about 2.1% of Ethereum ETF assets against about 0.2% for Bitcoin, a difference of close to ten times in intensity.

 

 

 

The complete week. October 12 to 16 produced $320.1 million of net outflows from Ethereum ETFs and $228.4 million from Bitcoin ETFs.

 

Flows concentrated in one fund on each side. BlackRock's ETHA accounted for roughly $299 million of the Ethereum total, more than 90%, while IBIT accounted for $165.4 million of the Bitcoin total, about 70%.

 

Measured against assets, Ethereum redemptions ran roughly ten times hotter. The $320.1 million equals about 2.1% of $14.946 billion, while $228.4 million equals about 0.2% of $104.290 billion.

 

Month-to-date pressure is heavier still. Per Yahoo Finance, Ethereum ETFs shed $954.8 million between October 1 and 16, about 6.4% of net assets, with October 13 the only positive session.

 

Price action points the same way. In the week to October 18, ether fell 3.6% against a 1.4% decline for bitcoin, so the selling exceeded the broad market move.

 

Falling assets are not the same as redemptions. On a $14.946 billion base, a 3.6% price decline alone removes roughly $540 million of net assets, more than the $320 million of actual redemptions, so the two must be read separately.

 

 

 

Per Farside, Ethereum ETFs lost $85.4 million on October 12, took in $24.8 million on October 13 in the only positive session of the month so far, lost $129.5 million on October 14 for the largest single day of the week, then $60.3 million on October 15 and $69.7 million on October 16, totalling $320.1 million across five sessions.

 

Bitcoin followed a different rhythm. Outflows of $65.4 million on October 12 were followed by inflows of $175.7 million on October 13, outflows of $261.4 million on October 14, a marginal inflow of $5.1 million on October 15 and outflows of $82.4 million on October 16, for a net $228.4 million. Only October 14 saw both move sharply together, which suggests the week was not a uniform risk-off episode but something more asset-specific.

 

 

The Ethereum side is extremely concentrated. BlackRock's ETHA lost $75.1 million, $109.8 million, $44.4 million and $69.7 million on the 12th, 14th, 15th and 16th respectively, roughly $299 million across the week and more than 90% of the total. Fidelity's FETH ran against the tide with small inflows of $8.1 million on the 13th and $2.4 million on the 15th. Grayscale's ETHE lost $18.3 million on the 15th, while its mini ether trust lost $10.3 million, gained $16.7 million and lost $18.8 million across the first three sessions.

 

Bitcoin is concentrated too, though slightly less so. IBIT lost $165.4 million for the week and FBTC lost $60.2 million, including a single-day exit of $152.7 million on the 14th, while Bitwise's BITB took in a marginal $2.2 million.

 

That breakdown matters. When one fund drives a product line's flows, a handful of large holders rebalancing can flip the entire curve, which is a different signal from broad-based retail redemption. Yahoo Finance likewise attributes the ETHA selling primarily to larger holders cutting exposure.

 

 

Absolute dollars tell only half the story. The reason $320.1 million matters more than $228.4 million is that it came out of a far smaller pool.

 

Per SoSoValue as of October 16, spot Ethereum ETFs held $14.946 billion against $104.290 billion for spot Bitcoin ETFs, making the latter about seven times larger. Dividing last week's outflow by each asset base gives roughly 2.1% for Ethereum and roughly 0.2% for Bitcoin. In the same five sessions, the Ethereum complex gave up close to ten times as much of itself.

 

Penetration adds another angle. Ethereum ETFs hold 5.07% of ether's market capitalisation against 6.35% for Bitcoin ETFs. The ETF channel has become the more established allocation route for bitcoin, while Ethereum's institutional base is thinner, which means a rebalance of equivalent size lands harder. For the equivalent long-run picture on the bitcoin side, our Bitcoin ETF flow tracker covers the structure.

 

Cumulatively, Farside puts lifetime net inflows at roughly $12.968 billion for spot Ethereum ETFs and roughly $56.949 billion for spot Bitcoin ETFs, so one week barely moves either. The issue is pace: October's $954.8 million of Ethereum outflows equals about 7% of all the money the product line has ever attracted, withdrawn in under three weeks.

 

 

This is the distinction most often lost in coverage, and the reason a tracking page earns its place.

 

The change in an ETF's net assets has two components: the net of creations and redemptions, and the price move in the underlying asset. Farside records the first, which is actual money entering or leaving. Headlines about assets shrinking usually describe the two combined.

 

Running last week's numbers makes it concrete. On a $14.946 billion base, ether's 3.6% decline in the week to October 18 removes roughly $540 million of net assets on price alone, against $320 million of actual redemptions. Looking only at the asset total would therefore read a price decline as capital flight and overstate the redemption pressure. The calculation is illustrative, since daily creation timing and the price path both affect the real figure.

 

The reverse distortion also exists. During a strong rally, net assets can rise even while redemptions continue, hiding the fact that money is leaving. Judge demand by creations and redemptions, judge position value by net assets, and do not substitute one for the other.

 

 

Price is the most direct explanation. Ether fell 3.6% in the week to October 18 against 1.4% for bitcoin, and ether now trades near $2,343.76, down 3.14% over 24 hours for a market capitalisation around $286.3 billion, while bitcoin sits near $82,918, up 1.01%, at roughly $1.67 trillion. Yahoo Finance reads ether's underperformance as selling pressure beyond the broad market decline.

 

The longer window is no kinder. Per the same report, as of October 17 ether was down 18.4% year to date, up 29.3% over 90 days and down 1.1% over the past month. In that configuration, a mid-term bounce inside a deeply negative year, institutional holders are more likely to trim into strength than to add.

 

A third factor is substitution. Yield routes for ether holders keep multiplying, and some demand that might once have arrived through an ETF now goes on-chain instead. Interactive Brokers launching ether staking this month is the clearest recent example, and the IBKR Ethereum staking guide sets out the eligibility, fees and exit waits. ETF shares generate no yield of their own, and that gap grows more visible when prices are flat or falling.

 

Worth repeating is that these are correlations rather than confirmations. Farside records amounts, not motives, and any attribution should carry that caveat.

 

 

The first item is whether ETHA stops bleeding. It holds more than a third of Ethereum ETF assets and produced over 90% of last week's outflow, so its direction effectively sets the curve.

 

Second is whether positive sessions string together. Only October 13 was positive between the 1st and the 16th, and two or three consecutive inflow days would be the first real sign of a turn, since one green print means little in this structure.

 

Third is intensity rather than headline dollars. Weekly outflow divided by net assets staying above 1% indicates continued pressure, while a drop below 0.5% is closer to ordinary noise.

 

Fourth is the relationship with bitcoin. If Bitcoin ETFs turn positive while Ethereum keeps bleeding, the split is asset-specific. If both move together, macro is the likelier driver, and the Federal Reserve meeting on October 27 and 28 is the obvious catalyst in this window.

 

Fifth is divergence between price and flows. Ether stabilising while outflows persist would indicate spot buyers absorbing ETF supply, which is a healthier structure than the two falling in step.

 

Prices usually move before the flow data is published, so the ETH spot market is the intraday reference

 

 

For James Mitchell, the signal in last week's data is not that Ethereum outflows exceeded Bitcoin's, but that the two flow curves are being driven by different things. Only October 14 saw both move sharply in the same direction, while the other four sessions diverged in direction or scale. Through most of 2024 and 2025 the two tracked closely, because the same pool of money was allocating to crypto as a category. Falling correlation means allocators are deciding asset by asset rather than sector-wide, which sets a higher bar for ether.

 

Two misreadings look likely. The first is comparing absolute dollars. The gap between $320.1 million and $228.4 million looks modest until each is divided by $14.946 billion and $104.290 billion of assets, at which point the intensity differs by close to ten times, and that is the fact requiring explanation. The second is treating falling net assets as capital flight. On last week's numbers the price effect removed roughly $540 million against $320 million of real redemptions, so combining them materially overstates the severity.

 

Three relationships deserve tracking from here. How far ETHA's single-fund direction diverges from the rest of the complex determines whether this is concentrated rebalancing or broad withdrawal. Whether weekly outflow as a share of assets falls from 2.1% back below 1% is the quantitative test of easing pressure. And the penetration gap, 5.07% for ether against 6.35% for bitcoin, shows whether institutional weighting between the two assets is being reset structurally rather than for a week.

 

Across assets, this resembles the early stage of dispersion within a sector in traditional markets. Once money stops flowing into crypto as a single category and starts separating bitcoin's store-of-value case from ethereum's utility case, the valuation logics decouple. That is healthy for long-run pricing, but during the transition, whichever side loses the category bid absorbs the larger swings.

 

 

 

Summing Farside Investors' daily data for the complete week of October 12 to 16, US spot Ethereum ETFs recorded net outflows of roughly $320.1 million and spot Bitcoin ETFs roughly $228.4 million. The Ethereum sequence ran outflows of $85.4 million, an inflow of $24.8 million, then outflows of $129.5 million, $60.3 million and $69.7 million, with October 13 the only positive session of the month so far.

 

 

Because the asset bases differ sharply. Per SoSoValue as of October 16, spot Ethereum ETFs held $14.946 billion in net assets against $104.290 billion for spot Bitcoin ETFs. Dividing each weekly outflow by its asset base gives roughly 2.1% for Ethereum and roughly 0.2% for Bitcoin. Similar dollar amounts impose very different pressure on differently sized pools, which is why flow comparisons require a size adjustment.

 

 

On the Ethereum side the concentration is extreme, with BlackRock's ETHA losing roughly $299 million over five sessions, more than 90% of the total, while Fidelity's FETH took in small inflows and Grayscale's ETHE lost $18.3 million. On the Bitcoin side, IBIT lost $165.4 million and FBTC $60.2 million, about 70% concentration. Flows dominated by one fund usually indicate a few large holders rebalancing rather than broad redemption.

 

 

Net outflow measures creations and redemptions of shares, which is real money moving. A fund's net assets also move with price. On a $14.946 billion base, ether's 3.6% decline in the week to October 18 removes roughly $540 million of net assets by itself, more than the $320 million of actual redemptions. Reading the asset total alone would therefore overstate redemption pressure, so demand should be judged by creations and redemptions.

 

 

Price is the immediate factor, with ether down 3.6% in the week to October 18 against 1.4% for bitcoin, which implies selling beyond the broad market move. The longer record is also unfavourable, with ether down 18.4% year to date as of October 17. Separately, staking and other on-chain yield routes absorb demand that might otherwise arrive through an ETF, while ETF shares pay no yield. These remain inferences, since flow data records amounts rather than motives.

 

 

Farside Investors publishes daily creations and redemptions broken down by fund, usually with a one-day lag and no weekend updates, so a complete week is only available the following Monday. SoSoValue publishes total net assets, the ratio to each asset's market capitalisation and cumulative net inflows. Methodologies differ slightly between sources, so stick to one when calculating relative measures such as outflow as a share of assets.

 

 

First, whether ETHA stops bleeding, since it holds more than a third of Ethereum ETF assets and effectively sets the direction. Second, whether two or three consecutive inflow days appear, because a single positive print means little. Third, whether weekly outflow as a share of assets falls from roughly 2.1% below 1%. Fourth, the direction relative to bitcoin, since Bitcoin turning positive while Ethereum bleeds would confirm an asset-specific split, with the Federal Reserve meeting on October 27 and 28 as the key macro date.
