According to reports from the Ethereum Foundation, Glamsterdam will activate on the Sepolia testnet at epoch 353,024 and slot 11,296,768 on October 6 at 13:53:36 UTC. The upgrade combines Amsterdam changes on the execution layer with Gloas on the consensus layer, representing Ethereum's next major scaling package. Sepolia node operators must update both execution and consensus clients before the scheduled network activation, while ordinary ETH holders and mainnet users do not need to take action for the Sepolia upgrade. As confirmed by the Ethereum core-developer testing agenda, this marks a crucial test of protocol changes with any mainnet rollout to be scheduled separately. The official Ethereum roadmap currently lists Glamsterdam for mainnet in Q4 2026, though the date has not been confirmed.
As reported by the Ethereum Foundation, Glamsterdam introduces enshrined proposer-builder separation (ePBS) through EIP-7732, moving the relationship between block proposers and specialized builders directly into Ethereum's protocol. Under the new structure, proposers include builder commitments to execution payloads, after which builders reveal the full payload, with Ethereum's protocol handling payment between builder and proposer. The upgrade also includes block-level access lists through EIP-7928, allowing clients to read state from disk and process transaction validation in parallel while making state-root calculations more efficient. These changes are designed to support greater capacity and improved market structure for block building, with capacity and block-building improvements needing to work reliably before users see the benefits.
According to the Ethereum Foundation, several EIPs change Ethereum's gas accounting to better match resources consumed when contracts create or access state. EIP-8037 raises and separately measures state creation costs, while EIP-8038 changes state access costs. The Foundation warns that applications relying on fixed gas stipends, hardcoded gas limits, or assumptions about remaining gas during execution could require changes. Earlier testing uncovered bugs involving consensus finality and EIP-8037 implementation, prompting additional testing before confirming the public fork. For successful testnet operation, agreement on mainnet rollout and whether cheaper, more capable infrastructure brings users and transaction demand are the relevant measures for Ethereum price prediction.
Ethereum currently trades near $2,695, showing less than 1% daily gains as the market processes the latest upgrade developments. According to CoinGecko data, ETH traded around $2,693–$2,695 on October 4, up roughly 0.7% over 24 hours but nearly flat over seven days. The token traded between approximately $2,678 and $2,697 during the latest 24-hour period, with a market capitalization near $328 billion. Ethereum has entered October holding close to $2,700 after reaching an intraday high around $2,775 on October 2, but failed to sustain the advance, falling back below $2,700 before stabilizing. Technical analysis identifies $2,775–$2,800 as the main resistance zone, with a clean break above this level potentially reopening $3,000, while $2,400–$2,500 remains key downside support area.
U.S. spot Ether ETFs recorded $118 million in net outflows during the latest trading week, contrasting sharply with the previous week when products attracted approximately $689.8 million. As reported by Arkham Intelligence, BlackRock's Ethereum funds had acquired approximately $1.57 billion worth of ETH during the preceding 20 days in mid-September, with ETHA accounting for around $1.27 billion and ETHB representing another $296.5 million. However, the latest data show Farside Investors recorded $59.6 million in combined U.S. spot Ether ETF outflows on September 30, followed by $55.4 million on October 1 and another $17.3 million on October 2. Exchange-flow data from CryptoQuant analyst R3N shows approximately 129,700 ETH leaving exchanges compared with 116,700 ETH entering them, representing the first clear divergence after weeks of closely matched flows.
