Ethereum ETF Outflows: What ETH Holders Check

US funds holding ether lost a net $140 million in the week to September 18, 2026. It is the first week of outflows since mid-August, and it ends a run of four consecutive weeks of inflows. At the same time the Ethereum price stands at $2,703 on Monday morning, a good 5 percent above the previous day. Price and capital flows are pointing in different directions.

If you hold ether, this is less a question about the price than a question about the wrapper: which structure your ether sits in, what that means for tax, and which deadlines are currently running. This article puts the numbers in context and names the points you can check against your own holdings.

Ether ETFs: $140 Million of Outflows in One Week

The figure comes from The Block's weekly flow review published on September 19, 2026. It shows that US spot ETFs on ether recorded a net outflow of $140 million for the trading week to September 18. That is the first negative week since the one that ended on August 14.

What happened inside that week is worth noting. On Friday, September 18, ether funds still took in $143.8 million. The weekly loss was therefore built up on the days before it and was almost, though not quite, recovered on the final trading day. Anyone reading the Friday number alone gets a different picture from someone looking at the full week.
