On April 28-29, 2026, the funds for Ethereum spot ETFs suddenly shifted direction. Data from SoSoValue showed that on April 28, there was a total net outflow of about $21.8 million across the products, with BlackRock's ETHA experiencing a net outflow of about $13.1697 million in one day, making it the product with the largest outflow that day; on April 29, the overall net outflow further increased to about $87.7 million, with Fidelity's FETH being the product with the largest net outflow for the day, and ETHA also recorded significant outflows. According to a single source from Panews, as of April 29, Ethereum spot ETFs had observed net outflows for at least three consecutive days, although the specific amount for April 27 has not yet been disclosed, and related statements await further data validation. It is important to emphasize that the aforementioned fund flow comes from third-party platforms like SoSoValue and Panews, rather than the official stance of the issuers or exchanges. Historically, there have been instances where the net outflow on April 28 was mistakenly reported as about $50.48 million before being corrected to about $21.8 million, indicating that statistics still carry risks of revisions and discrepancies in measurement standards.

Just around April 30, following two consecutive days of accelerated withdrawal from ETFs, on-chain analyst Onchain Lens monitored that a whale opened a short position of 14,512 ETH with 20x leverage in about two hours, with a notional value of approximately $32.69 million and a liquidation price of about $2,766.42. The identity, source of funds, and specific motives of this address are currently unknown, but at a time close to the substantial net outflow of tens of millions of dollars from the ETFs, the occurrence of such high leverage and a single order nearing $33 million for a short position has led to a clear temporal overlap of "institutional funds reducing positions + whale aggressively shorting." In terms of market pricing, this overlap is typically interpreted as one of the signals indicating short-term price pressure, but in the absence of more evidence, we can only view it as a hypothesis regarding short-term downward pressure and cannot elevate their relationship to a verifiable causal chain.

Net outflow of nearly $110 million over two days: ETF funds sharply shift

From the perspective of fund flows, April 28-29 marked a clear turning point. According to the third-party data platform SoSoValue, the total net outflow for Ethereum spot ETFs on April 28 was approximately $21.8019 million, with BlackRock’s ETHA alone contributing about $13.1697 million, accounting for nearly 60% of the total outflow for that day. Early reports had mistakenly reported the total net outflow for April 28 as about $50.48 million, which was later corrected to about $21.8 million after updates from SoSoValue, indicating that the narrative surrounding the fund flow on this day had actually undergone a "data revision." Subsequently, on April 29, the total net outflow recorded by SoSoValue quickly expanded to about $87.7256 million, nearly quadrupling the previous day's figures; on that day, Fidelity’s FETH saw the largest single product net outflow, while BlackRock's ETHA also observed significant outflows. Referencing the single source data from Panews, FETH has seen a historical total net inflow of about $2.241 billion since its launch, and under this volume, a daily outflow at the tens of millions of dollars level would not immediately change the long-term picture, but it is sufficient to change the marginal direction of funds in a short time. When considering both days, the total net outflow for Ethereum spot ETFs from April 28-29 approached the $110 million mark, which represents a relatively prominent negative funding event within a conventional trading week.

If we push the time window back by one day, Panews reported that as of April 29, Ethereum spot ETFs had experienced three consecutive days of net outflows, at least covering the trading days of April 27-29. However, it should be clarified that the specific net outflow amount for April 27 has not been disclosed, and there has yet to be a clear figure provided by SoSoValue or other data sources. Therefore, this "three consecutive days" statement remains at the level of a single source, awaiting further data cross-verification. More importantly, all the quantifiable data regarding net inflows and outflows in this round comes from the third-party platform SoSoValue, rather than official disclosures from regulatory agencies or ETF issuers. This means that the statistical measures could differ from those maintained by various market participants, and data may also undergo revisions within and across days; the case of April 28 being revised from "approximately $50.48 million outflow" to "approximately $21.8 million outflow" already highlights the need for investors to remain sensitive to "data versions" when interpreting related charts and reports. Any conclusions drawn from these figures are more appropriately viewed as high-frequency observations of changes in funding sentiment, rather than finalized official settlement results.

BlackRock and Fidelity lead selling: Movements of major products

Following the flow of funds data, one can see that the selling pressure is highly concentrated on top products. On April 28, the total net outflow for Ethereum spot ETFs recorded by SoSoValue was approximately $21.8019 million, with BlackRock’s ETHA contributing about $13.1697 million, which accounted for nearly 60% of the overall net outflow that day. In the inquiry of "who is selling," this percentage naturally positions ETHA as the core source of selling pressure for that day. However, it must be emphasized that these figures are sourced from third-party platform statistics, and can still be revised due to adjustments in measurement methodology, reflecting more about the relative distribution of funds across different products on that day rather than direct evidence of active selling by the issuers.

By April 29, a significant change in the funding structure was observed: SoSoValue data showed that on that day the total market net outflow expanded to about $87.7256 million, with Fidelity’s FETH surpassing ETHA as the product with the largest net outflow; ETHA also recorded a large net outflow on the same day. This means that on the second day of increased net outflows, both BlackRock and Fidelity saw funds withdraw, rather than one increasing while the other decreased, indicating a trend of "synchronized position reduction" among leading products. This synchronicity has strengthened the market's interpretation of "the institutional side overall shrinking their Ethereum risk exposure," but from a data perspective, we can currently only confirm that during these two days from April 28-29, net outflows were mainly concentrated in a few large-scale products.

If we extend the perspective from two-day fluctuations to product stock, the significance of short-term outflows will be notably diluted. According to Panews' single source statistics, as of April 29, Fidelity's FETH has recorded a historical total net inflow of about $2.241 billion since its launch. By this measure, the current daily outflows at the tens of millions of dollars level are just a small part of its accumulated net inflow, appearing more akin to profit-taking or phased portfolio adjustments rather than a comprehensive "supply disruption." It is also necessary to note that the assertion of "the recent sustained multi-day net outflows being predominantly sold by BlackRock products" currently only appears in research briefs and market transcripts, with no cross-verification from multiple data sources or confirmation from public documents from the issuers. It can only be discussed as a market opinion at most, rather than established as a verified fact. As of April 30, neither BlackRock nor Fidelity has issued official explanations regarding the fund flow of their respective Ethereum spot ETFs, and media interpretations largely rely on third-party data from SoSoValue, Panews, etc. Under this information structure, summarizing the current net outflows as "BlackRock leading the selling" is more appropriate as an emotional label than a conclusive statement.

Whale shorts with 20x leverage: $32.69 million weighed on one side

Almost simultaneously with the debate over ETF net outflows in the secondary market, a sharply directional large order also appeared on-chain. According to on-chain analyst Onchain Lens, around April 30, within approximately two hours, a whale concentrated on a derivatives platform opened a short position of 14,512 ETH, using about 20x leverage, corresponding to a notional value of about $32.69 million. This means that this exposure was not passively accumulated through multiple small orders, but rather formed a massive directional bet from a single address within a very short timeframe. It is important to emphasize that this information comes from third-party on-chain analytics accounts and is not any official announcement from exchanges or clearinghouses. Currently, the public can only see the scale and structure of this position itself.

From the perspective of risk exposure, the liquidation price of this short position is approximately $2,766.42 per ETH, which is a key parameter for understanding its risk appetite. Calculated using 20x leverage, the margin relative to the nominal exposure is quite thin, meaning that once the ETH price significantly climbs, nearing or even breaching the $2,766 line, this address may trigger forced liquidation mechanisms, buying back to cover its shorts rather than voluntarily closing the position. This structure essentially amplifies the risk of upward price fluctuation by about 20 times: for the bear, as long as the market runs against them into the liquidation zone, losses are nearly locked in with very limited room for proactive adjustments.

A large-scale, high-leverage short unilateral bet like this can easily amplify market participants' subjective perception of "downside risk" on an emotional level. For investors already monitoring ETF net outflows, this approximately $30 million short position is naturally incorporated into the same narrative framework, reinforcing the impression that "large funds are betting on short-term weakness"; for derivative market traders, it may also become a symbolic event to gauge emotional bias. However, the current publicly available information has not revealed any tags, sources of funds, or historical trading records for this whale address, making it impossible to determine whether it is a hedge, speculation, or other strategic arrangement. All interpretations relating to "intent" remain at the market speculation level. At this stage, we can only confirm that at a time when ETF funds are continuously flowing out, an on-chain large position shorting 14,512 ETH with 20x leverage indeed emerged, while further conclusions are still pending.

Institutional fund withdrawal meets whale shorting: how emotions resonate

From a timeline perspective, these two forces are almost seamlessly connected: according to a single source from Panews, there have been continuous net outflows for Ethereum spot ETFs since at least April 27; on April 28, the total net outflow recorded by SoSoValue was about $21.8019 million, which expanded to about $87.7256 million on the 29th, both days led by top products causing the funding situation to decline. Just following this, on April 30, within about two hours, Onchain Lens detected a whale opening a short position of 14,512 ETH with 20x leverage, with a notional value of approximately $32.69 million and a liquidation price of about $2,766.42. Both events occurred within a 72-hour window, creating a visual narrative of "offshore capital withdrawal and high-leverage on-chain bets on declines." However, we can currently only confirm the temporal overlap without evidence of direct causality, nor any signs that the whale has any relation to any ETF issuers or traditional financial institutions.

From the perspective of emotional interpretation, large consecutive net outflows from ETFs are often simply attributed to "institutional position reduction" or "turning bearish," especially during such a phase of significant expansion in net outflows from tens of millions to nearly $90 million on April 29, making it easier to amplify as a trend signal. However, the fund flow itself is merely a snapshot within the lifecycle of the product; for example, referring to Fidelity's FETH, Panews has shown a historical total net inflow of approximately $2.241 billion — thus even single-day outflows in the tens of millions, while they may suppress sentiment in the short term, are still just part of a cyclical fluctuation in the long-term curve. More realistically, these outflows may encompass multiple motives, including profit-taking, portfolio reallocation, and cross-category arbitrage, yet the market interprets them uniformly as "collective bearish," which is inevitably an oversimplification.

In contrast, the large-scale 20x leverage short from the on-chain perspective is clearer in terms of price level, leverage, and liquidation line, making it more easily seen as an aggressive bet on short-term declines, strengthening the market's imagination of downward pressure alongside ETF fund withdrawals: under a pessimistic narrative, it may be interpreted as a "confirmation signal," pushing more participants to reduce positions or short in the spot and derivatives markets. However, that same position, when prices rebound and approach around $2,766, may also turn into potential "ammunition"—once forced liquidation is triggered, it could actually amplify upward volatility, creating a short squeeze in the short term. In other words, regardless of whether it is the ETF net outflow or the whale's high-leverage shorting, the more reliable conclusion at present is not that the direction has been locked, but rather that the price volatility range might be widened in the near future. It should be emphasized that the above judgments are entirely based on third-party data from platforms such as SoSoValue, Panews, and Onchain Lens, and include market statements like "BlackRock leading sales" which are still awaiting verification; as of April 30, there had been no public statements from the ETF issuers and related exchanges, and investors should maintain sufficient skepticism and buffer space regarding this narrative of "institutional fund withdrawal + whale shorting."

Next, keep an eye on three things: funds, leverage, and volatility

The current visible picture is that on April 28-29, Ethereum spot ETFs had a total net outflow of about $110 million, and the leading products BlackRock's ETHA and Fidelity's FETH were both on the list of funds withdrawing; almost simultaneously, on April 30, there was a large short position of 14,512 ETH, with 20x leverage and a notional value of approximately $32.69 million. Next, the first focus should be on the fund flow itself from the ETFs—under the condition of only having data up to April 30, whether there will be continued net outflows or a reversal to single or multi-day net inflows in the coming days will directly influence whether the narrative of "capital withdrawal" holds water. Second, it is essential to watch the fate of the whale and similar high-leverage short positions: will they continue to add to their positions, or will they be forced to reduce positions due to price reversals or even hit the liquidation price around $2,766.42? Third, the actual volatility path of ETH spot prices should be examined to see whether it matches the changes in funds in and out and the leverage positions— for instance, in the context of net outflows and accumulation of shorts, whether prices indeed trend downward to the corresponding extent or show stronger passive support.

In terms of methods, if regular investors want to adjust their positions based on this, a more prudent approach would be to consider ETF fund flow (SoSoValue, Panews, etc.), monitoring of large on-chain leveraged positions (such as Onchain Lens), and the fluctuations in exchange spot prices comprehensively, rather than being led by any single dimension. The total net outflow on April 28 was reported by some media as about $50.48 million, later revised to $21.8019 million, which already illustrates that there are discrepancies in data versions and retrospective revisions; the historical total net inflow of around $2.241 billion for Fidelity’s FETH is currently only a single source from Panews. When using third-party data, it is crucial to pay attention to the source explanations and revision histories while also striving for cross-validation from multiple sources to avoid treating unverified figures as solid "evidence" for large bets. In the absence of official statements from issuers and exchanges and longer sample periods, extreme conclusions such as "institutions are collectively bearish" or "the market has entered a bear phase" should be approached with caution, considered as hypotheses that require further data validation rather than already proved conclusions.
