September 15 (Crypto-News.Net) – Ethereum ETF inflows turned positive again on September 14, 2026, when U.S. spot Ethereum exchange-traded funds recorded $121.1 million in net inflows, according to data from Farside Investors.
BlackRock’s iShares Ethereum Trust (ETHA) led the session with $80.5 million. Other positive prints on the Farside sheet included Grayscale’s Ethereum Mini Trust (ETH) at $16.2 million, ETHB at $14.4 million, Fidelity’s FETH at $8.9 million, and TETH at $6.5 million. QETH showed $5.4 million in net outflows the same day.
Farside’s recent daily totals show a mixed path into that print. The table lists $216.4 million in net inflows on September 11, $29.9 million in net outflows on September 10, $34.7 million in net inflows on September 9, and $24.3 million in net outflows on September 8. ETHA also led on September 11, with $148.8 million that day.
Those figures sit on Farside’s Ethereum ETF flow pages, which track primary-market activity across the main U.S. spot Ethereum products. Crypto-News.Net has previously covered large Bitcoin ETF inflows on the same provider’s Bitcoin table, and separately reported the September 14 U.S. spot Bitcoin ETF session when those products posted $159.9 million in net inflows.
Ethereum ETF inflows and the Glamsterdam Sepolia date
On the protocol side, ethereum.org’s Glamsterdam roadmap page lists the upgrade status as testing on devnets. The next milestone shown is a Sepolia fork on October 6, 2026. Mainnet is described as expected in the fourth quarter of 2026, with the date not yet confirmed. The page points to Forkcast for live progress tracking.
Glamsterdam is named from an execution-layer label tied to Amsterdam and a consensus-layer label tied to Gloas, according to ethereum.org. The page places the work after the Fusaka upgrade and describes a focus on scaling Ethereum’s base layer, including proposals discussed under enshrined proposer-builder separation and block-level access lists. ethereum.org presents the upgrade as one step on the longer roadmap. The October 6 Sepolia date is a listed milestone, not a completed mainnet activation.
