- US spot Ethereum ETFs pulled in $196.9 million in net inflows for the week ending September 11, 2026 — a fourth straight positive week.
- Spot Bitcoin ETFs bled $462.7 million over the same week, snapping a three-week inflow streak.
- BlackRock's iShares Ethereum Trust led Friday's flows with $148.8 million.
The Ethereum ETF story pulled sharply ahead of Bitcoin last week. US spot Ethereum funds took in $196.9 million in net inflows for the week ending September 11, 2026, their fourth consecutive positive week, according to CryptoBriefing. Bitcoin funds went the other way, shedding $462.7 million and ending a three-week inflow run. That is a $660 million swing between the two in a single week.
BlackRock Drove the Ethereum Surge
Friday did most of the work. BlackRock's iShares Ethereum Trust brought in $148.8 million on September 11 alone, pushing the weekly Ethereum total firmly positive after softer flows earlier in the week, as reported by CoinPaprika. When a single issuer moves the weekly number that much, it usually signals a deliberate institutional rotation rather than retail noise.
Prices Slide as the Fed Meets
The flows landed against a nervous market. Bitcoin opened at $78,181 on September 15 before sliding toward $76,900, while Ether eased from $2,515 to about $2,480, per Yahoo Finance. Traders are bracing for the Federal Reserve's two-day meeting, with the CME FedWatch tool putting the odds of a rate hike at 92.5%. Rising rates usually pull money out of risk assets, which makes the steady Ethereum inflows more notable, not less.
What the Divergence Signals
Four straight weeks of Ethereum inflows while Bitcoin funds leak is not random — it looks like a rotation. Part of the driver is the revised CLARITY Act, whose White House-backed concessions have lifted regulatory optimism for smart-contract platforms like Ethereum. The number to watch now is whether Ether's ETF streak survives the Fed decision and any market reaction that follows. For ongoing coverage, see our Ethereum news and the live crypto markets page.
For context, spot Ethereum ETFs only launched in the United States in 2024, so their ability to now out-pull Bitcoin products is a meaningful shift in how large investors view the second-biggest cryptocurrency. Bitcoin ETFs still hold far more total assets, and one soft week does not undo that lead. But momentum matters to allocators, and a full month of steady Ether demand builds a case that is harder to ignore. The next weekly flow report, due after the Fed meeting, will show whether this was a one-off rotation or the start of a longer trend. For now, the Ethereum streak stands at four weeks and counting, and it is doing so while prices drift lower and rate-hike fears build.
