Ether recorded its worst October since 2018, falling approximately 13.6% over the month against a backdrop of record ETF outflows, dormant whale liquidations, and structural fee-revenue erosion. The decline nearly tripled Bitcoin's roughly 5% drawdown over the same period, pushing the ETH/BTC ratio toward multi-year lows near 0.029.
U.S. spot Ether ETFs shed an estimated $1.45 billion in October, eclipsing the previous monthly record of $1.42 billion set in November 2025. BlackRock's ETHA led fund-level outflows. Simultaneously, wallets dormant for years moved over 160,000 ETH — worth upward of $348 million — to exchange addresses. Ethereum's fee burns now cover roughly 2% of new issuance, leaving the network mildly inflationary at approximately 0.64% annualized. The Glamsterdam upgrade delay, triggered by ChainSecurity flagging 13 at-risk smart contracts, removed one near-term catalyst. Taken together, the data describes a network whose economic model faces a dual challenge: institutional capital leaving through ETF wrappers and on-chain economic activity migrating to Layer 2 networks.
Ether entered October 2026 trading near $2,600 and exited the month around $2,230, a decline of approximately 13.6%, according to data from CoinGecko and CoinMarketCap. This marks the token's worst October in eight years, per CoinOtag data. Bitcoin, by comparison, declined roughly 5% over the same period, ending near $77,380.
The ETH/BTC ratio, a widely tracked measure of Ethereum's relative performance, hovered near 0.029 in late October. The ratio bottomed at 0.02578 on June 6, 2026 — a level last seen in 2020 — and has failed to meaningfully recover. Over the trailing 12 months through October 30, Ether fell 41.3% in dollar terms. Bitcoin declined approximately 11% over the same window.
Ethereum's market capitalization stood at roughly $268 billion on October 30, against Bitcoin's $1.33 trillion, according to Fortune. The Binance hack on October 29, which drained an estimated $6.3 billion across multiple chains, accelerated the late-month selloff. Ether briefly traded below $2,200 on October 30 as $1.68 billion in cross-market liquidations swept leveraged positions.
U.S. spot Ether exchange-traded funds posted cumulative net outflows of approximately $1.45 billion in October 2026, according to data compiled by TokenPost and Cointelegraph. This surpassed the prior record of $1.42 billion withdrawn in November 2025.
The outflow pattern accelerated through the month:
| Date | Daily Net Flow | Notable Fund Flows | |------|---------------|-------------------| | Oct 7 | -$160.9M | BlackRock ETHA: -$116.1M | | Oct 21 | Mixed | Grayscale ETH Mini: +$28.1M; ETHA: -$29.3M | | Oct 26 | -$88.6M | ETHA: -$104.7M; Fidelity FETH: +$16.1M | | Oct 27 | -$60.2M | ETHA: -$93.3M; FETH: +$28.6M | | Oct 28 | -$21.4M | Broad-based outflows | | Oct 29 | -$105.5M | ETHA: -$71.7M; FETH: +$2.9M |

BlackRock's iShares Ethereum Trust (ETHA), the largest spot Ether ETF by assets under management at $7.29 billion, accounted for a disproportionate share of outflows. According to Unchained Crypto, ETHA represented roughly 82% of October's net redemptions through the first three weeks. Fidelity's FETH and Grayscale's staking mini ETF attracted intermittent inflows but were insufficient to offset the ETHA-led exodus. Five-day outflows at one point reached $506.3 million, the highest such stretch since January 23, 2026.
The outflow trajectory stands in contrast to spot Bitcoin ETFs, which continued to attract modest inflows throughout October. This divergence underscores a growing institutional preference gap between the two largest crypto assets.
On-chain analytics tracked substantial movements from long-dormant Ethereum wallets during October. According to BeInCrypto, wallets inactive for multiple years transferred roughly 56,000 ETH — worth over $140 million at prevailing prices — to exchange deposit addresses at Coinbase and Kraken, signaling potential sell intent.
In a separate cluster of transactions, whale addresses reduced aggregate holdings by approximately 160,000 ETH, valued at over $348 million, according to on-chain data cited by U.Today and Digital Today. Analyst Ali Martinez noted that a single whale held a $214 million leveraged long position that faced liquidation risk if ETH breached $2,180.
This dual selling pressure — institutional via ETFs, and organic via on-chain whale movements — created what amounts to a two-front capital outflow. New inflows from staking or DeFi activity were insufficient to absorb the supply.
Ethereum's fee revenue, once a central pillar of the "ultrasound money" thesis, has collapsed. According to data cited by CryptoSlate and TokenPost, daily gas fee revenue declined from over $30 million at peak levels to roughly $500,000 — a drop exceeding 98%. On October 17, 2026, network fees totaled $213,212, per SahmCapital.
The cause is structural: the Dencun upgrade (March 2024) introduced blob data availability for Layer 2 rollups, dramatically reducing the cost of posting data to Ethereum mainnet. The result has been a migration of economic activity to L2 networks:
According to KuCoin News, the combined Ethereum L2 ecosystem processed the majority of network transactions while contributing minimal fees back to mainnet.
The burn mechanism, introduced via EIP-1559, now destroys a negligible fraction of new supply. From January 1 to October 9, 2026, Ethereum's net supply increased by approximately 778,413 ETH, with fee burns offsetting just 2.074% of the 796,623 ETH in gross issuance, according to TokenPost. The 30-day burn-to-issuance ratio on October 17 fell to 0.46%. Ethereum's annualized inflation rate stands at 0.64%, roughly matching Bitcoin's post-halving rate of approximately 0.8%, but without Bitcoin's fixed supply cap.
Buterin himself acknowledged the problem in February 2026, stating that the original Layer 2 vision "no longer makes sense" and that progress toward fully decentralized and interoperable L2s had been "far slower and more difficult than originally expected," according to The Block.
On October 22, Ethereum core developers canceled the planned October 26 activation of the Glamsterdam hard fork on the Hoodi testnet, according to CoinDesk and Cointelegraph. The postponement followed a disclosure by smart-contract security firm ChainSecurity, which identified 13 deployed contracts vulnerable to a class of attacks known as "insufficient gas griefing."
The at-risk contracts relate to two Ethereum Improvement Proposals: EIP-8037 and EIP-8038, which restructure how the network charges for state creation and access. Under the proposed rules, gas used to create certain records can be restored when changes are reverted. ChainSecurity warned this could allow attackers to permanently record failed operations by deliberately providing insufficient gas.
No replacement date has been announced for the Hoodi testnet activation or for the eventual mainnet deployment. Developers had previously targeted a mainnet launch by year-end 2026. The delay removes a near-term technical catalyst and raises questions about Ethereum's ability to ship upgrades on schedule — the next planned fork, Hegotá, is not expected until 2027.
Ethereum's staking landscape continued to evolve in October, though in a way that further concentrates economic activity away from mainnet fee generation. According to data from multiple sources including TokenPost and CryptoDaily:
The declining validator count despite rising total staked ETH reflects the Pectra upgrade's introduction of validator balance consolidation — fewer validators holding larger individual stakes. Staking yields have compressed steadily, falling below 3% and approaching levels where opportunity cost becomes material relative to traditional fixed income.
Grayscale's Ethereum Staking Mini ETF, which launched earlier in 2026, represented one of the few institutional products attracting net inflows during October, pulling in $28.1 million on October 21. The product's relative success suggests institutional demand for yield-bearing ETH exposure persists even as directional capital exits.
Ethereum's October performance encapsulates a set of challenges that are structural, not cyclical. The ETF outflow record, whale selling, and fee-revenue collapse are not isolated events but symptoms of a network in economic transition. Layer 2 networks have successfully scaled Ethereum's throughput — but in doing so, they have redirected the value capture that once accrued to mainnet validators and ETH holders via the burn mechanism.
The data does not support a narrative of network failure. Ethereum processed JPMorgan's expansion of JPM Coin to its mainnet in October. DTCC's tokenization infrastructure runs on it. DeFi protocols like Aave continue to operate at scale. The network's role as settlement infrastructure for institutional finance is, by most measures, expanding.
But settlement infrastructure and speculative asset are different value propositions. Ether's October rout suggests the market is repricing the token to reflect the former rather than the latter. The Glamsterdam delay compounds this by delaying improvements that could address fee capture. Until Ethereum's roadmap delivers a credible mechanism to recapture economic value from L2 activity — or until the market reprices ETH as pure infrastructure collateral — the structural headwinds identified in this report are likely to persist.
