US spot Ethereum ETFs ended a 12-day run of net inflows on Sept. 3, 2026, posting $48.08 million in outflows after pulling in about $1.62 billion over the streak, according to Decrypt, citing SoSoValue data. BlackRock’s iShares Ethereum Trust (ETHA) led the reversal with $53.4 million in outflows that day.
What happened?
Ethereum ETF inflows had strung together 12 consecutive positive sessions worth roughly $1.62 billion before the streak broke on Wednesday, Sept. 3, Decrypt reported. On the reversal day, the funds saw $48.08 million leave, with BlackRock’s ETHA accounting for the bulk at $53.4 million in outflows — meaning other ETH funds took in money even as the category turned net negative.
XRP ETFs snapped a streak of their own the same day, Decrypt and Cointelegraph reported. An 11-session run that had brought in about $170 million ended with $7.2 million in outflows, attributed almost entirely to Bitwise’s XRP fund; cumulative inflows into US XRP ETFs stood near $1.68 billion. Bitcoin ETFs, meanwhile, rebounded on Sept. 3, illustrating a rotation among the three categories rather than a broad exit, according to Cointelegraph.
Why does it matter?
ETF flow data is one of the clearest windows into institutional demand for crypto exposure through regulated wrappers, and Ethereum products have become a meaningful channel since launching in 2024. A 12-day inflow streak worth $1.62 billion signals sustained appetite; a single down day does not undo it. Decrypt has separately reported that BlackRock’s ETHA has been the dominant driver of ETH ETF flows through 2026 — which is why its $53.4 million outflow was large enough to flip the whole category negative even as peers stayed positive.
It is worth stressing what these figures are and are not. They measure creations and redemptions in the funds, not the price of Ether, and daily numbers are volatile and frequently revised. Reporting the flow event is more durable than reading a one-day move as a trend. For ongoing coverage, see our Ethereum section.
How did the streak build?
The 12-day run was the continuation of a stretch that began in mid-August. Decrypt reported that ETH funds logged nine consecutive sessions of inflows from Aug. 17, worth $1.42 billion in aggregate per Farside Investors data, with BlackRock’s ETHA alone accounting for $1.02 billion — about 72% of the category’s intake over that window. One Thursday during the run, US spot Ethereum ETFs pulled in $225.8 million, their strongest single day since Oct. 28, 2025, nearly matching Bitcoin ETFs’ $242.3 million that same day — a sharp narrowing from Aug. 17, when Bitcoin funds took in roughly ten times Ethereum’s amount, according to Decrypt.
Here is how the three categories looked on the Sept. 3 reversal day, per Decrypt citing SoSoValue:
| Category | Sept. 3 flow | Streak context |
|---|---|---|
| Ethereum ETFs | -$48.08M | Ended 12-day, ~$1.62B inflow run |
| XRP ETFs | -$7.2M | Ended 11-day, ~$170M inflow run; ~$1.68B cumulative |
| Bitcoin ETFs | Net positive (rebound) | Recovered as ETH and XRP paused |
How are ETF flows measured?
Net flow is the dollar value of new shares created minus shares redeemed across all issuers in a category on a given day. Data aggregators such as SoSoValue and Farside compile issuer-level numbers; the figures cited here come from SoSoValue and Farside via Decrypt. Because different trackers reconcile late data differently, small discrepancies between sources are normal, and single-issuer swings — like ETHA’s on Sept. 3 — can dominate the category total.
What to watch next
Watch whether the ETH category returns to net inflows in the sessions after Sept. 3, whether ETHA resumes its role as lead buyer, and how XRP funds behave after their 11-day streak ended. Also worth tracking is the interplay among Bitcoin, Ether and XRP ETF flows: Sept. 3 showed Bitcoin rebounding while ETH and XRP paused, a rotation pattern that flow data will confirm or contradict over the coming weeks.
Context matters when reading these numbers. A single day of outflows does not reverse a multi-week accumulation, and the concentration of ETH flows in one fund — BlackRock’s ETHA — means the category total can swing on a single issuer’s activity rather than a broad shift in sentiment. Cumulative figures give the steadier picture: even after the reversal, US XRP ETFs had drawn roughly $1.68 billion since launch, per Decrypt, and the ETH streak had added about $1.62 billion before it paused. None of this is a forecast — these are events to monitor, not price calls.
