In a nutshell: Ethereum ETF inflows stayed positive for a seventh straight trading day on Monday, September 28, 2026, with about $17.1 million in net creations (Farside Investors via CoinNess). BlackRock’s ETHA led at roughly $15.4 million. That soft daily print sits on a stronger week: US spot ether ETFs attracted nearly $690 million in net inflows, per FXStreet and CryptoBriefing.

What Happened: Ethereum ETF Inflows Extend to 7 Days
US spot ether exchange-traded funds recorded about $17.1 million in combined net inflows on September 28, extending positive flows to seven consecutive trading days, according to Farside Investors data relayed by CoinNess. BlackRock’s iShares Ethereum Trust (ETHA) accounted for roughly $15.4 million; 21Shares’ TETH added about $1.7 million. No fund in the spot ether complex posted a net outflow that session, TokenPost reported.
The daily number is modest next to earlier September prints — TokenPost noted it cooled from about $87 million the prior session — but a seventh green day still matters. Institutional creations did not flip to red while Bitcoin sat near the low $83,000s and risk assets digested higher Treasury yields.

Weekly Context: Nearly $690M Behind the Streak
FXStreet reported that US spot ether ETFs attracted almost $690 million in net inflows last week, reversing earlier September outflows that included more than $220 million leaving the complex on September 16.
CryptoBriefing put ETHA at about $15.35 million on September 28 — roughly 5,730 ETH through BlackRock’s regulated vehicle — and said ETHA alone took about $326 million of that weekly haul. By late September 2026, ETHA’s cumulative net inflows had crossed $13 billion, with the broader spot ether ETF category holding roughly $17.7–$17.8 billion in AUM (about 5.4% of Ethereum’s market cap when ETHA and BlackRock’s staked product ETHB are counted together). CryptoBriefing also noted ETHB — launched March 2026 — had posted zero net-outflow days since launch as of that reporting.
What Ethereum ETF Inflows Mean for Everyday Investors
You do not need to trade ETHA shares to care about ethereum ETF inflows:
- Creations are spot demand. When an ETF takes in cash, authorized participants typically deliver or acquire actual ETH — unlike leveraged futures chasing a move.
- A soft day can sit on a strong week. $17.1 million is quiet; nearly $690 million over a week is not. Zoom out before reacting to one print.
- Flows reverse fast. Mid-September’s $220M+ outflow day is the reminder: today’s streak is information, not a guarantee.
- ETFs are not the only on-ramp. If you buy ether on an exchange, custody still matters — see our crypto wallet guide and the parallel product explainer in Bitcoin ETF Explained.
None of this is a recommendation to buy or sell ETH, ETHA, ETHB or any other product.

- Glamsterdam track: FXStreet notes Ethereum’s next major upgrade is eyed for Q4 2026, with a Sepolia testnet fork scheduled for October 6. Calendars can slip; treat roadmap news as context, not a price target.

FAQ
How large were the latest Ethereum ETF inflows?
On September 28, 2026, US spot ethereum ETF inflows totaled about $17.1 million net — the seventh straight positive day — with BlackRock’s ETHA contributing roughly $15.4 million (Farside via CoinNess; CryptoBriefing).
Why does a $17M day matter if last week was ~$690M?
The daily print shows whether the streak is intact. The weekly total shows how much capital actually moved. Both matter; neither is a trading signal by itself.
Are Ethereum ETF inflows financial advice?
No. Fund-flow news explains institutional demand in regulated products. It does not tell you what size or timing fits your situation. For US tax basics, see our crypto taxes guide — and speak with a qualified advisor when needed.
