U.S. spot Ether funds posted record weekly outflows near $796 million

Data available on September 27, 2025 showed that U.S. spot Ether exchange-traded products had recorded approximately $796 million in net outflows across the five trading sessions from September 22 through September 26. The result was the group’s largest weekly withdrawal since the products began trading in July 2024, making it a significant test of institutional demand during a broad cryptocurrency selloff.

Farside Investors’ fund-flow table recorded daily totals of negative $76.0 million on September 22, negative $140.8 million on September 23, negative $79.4 million on September 24, negative $251.2 million on September 25 and negative $248.4 million on September 26. Adding those displayed, rounded figures produces a Coinburn calculation of negative $795.8 million.

A contemporaneous report from The Block, citing SoSoValue, placed the weekly total at negative $795.6 million. The roughly $0.2 million difference is immaterial to the record but should not be hidden: the providers may use different rounding conventions, update times or treatment of individual products. Accordingly, the headline uses “near $796 million” instead of implying false precision.

Redemptions spread across the trading week

The negative result was not confined to one session. Each of the five trading days ended with net outflows in the Farside table, and the two largest withdrawals occurred on September 25 and September 26.

Fidelity’s FETH accounted for approximately $362.3 million of the weekly outflow when Coinburn sums Farside’s displayed daily figures. BlackRock’s ETHA accounted for approximately $241.5 million. On September 26 alone, ETHA recorded negative $199.9 million and FETH negative $74.4 million, partly offset by positive readings of $8.0 million for 21Shares’ TETH and $17.9 million for Grayscale’s ETHE.

Those figures describe estimated net creations and redemptions in exchange-traded products, not ordinary exchange trading volume. A net outflow indicates that redemptions exceeded creations during the measurement period. It does not demonstrate that every reported dollar produced a simultaneous open-market sale of Ether, nor does it identify the motives of the underlying investors.

Why the record mattered

The funds had become a regulated securities-market channel through which investors could obtain spot Ether exposure. The Securities and Exchange Commission’s May 23, 2024 order approved exchange rule changes to list and trade shares of multiple Ether-based exchange-traded products, while noting that each product still required an effective registration statement before trading could begin.

By September 27, 2025, the weekly reversal therefore offered a concrete measure of institutional positioning rather than an informal survey of sentiment. SoSoValue’s reported negative $795.6 million narrowly exceeded the approximately $787.7 million outflow it calculated for the week ending September 5.

The move also occurred alongside weakness in the underlying asset. The Block reported that Ether had traded below $4,000 on September 25 and September 26 before recovering to roughly $4,020 around the time of its 7:22 p.m. Eastern report on September 27. That price was a contemporaneous market observation, not an official close: cryptocurrency trades continuously, and values differ by venue and timestamp.

What the evidence cannot establish

The parallel timing supports an interpretation that fund redemptions and weaker Ether prices were parts of the same risk-reduction episode. It does not establish which one caused the other. The surviving datasets also cannot reveal whether investors permanently abandoned Ether exposure, shifted to other vehicles, hedged elsewhere or later reversed the redemptions. The defensible event-day conclusion is narrower: the U.S. spot Ether product group completed its largest net-outflow week on record through September 26, based on data available September 27, 2025.
