Glamsterdam Test Advances as ETH Rebounds, ETF Outflows Weigh
Ethereum’s Glamsterdam upgrade is scheduled to activate on the Hoodi testnet at 17:42:48 UTC on October 26, following its October 6 rollout on Sepolia. The test will raise the testnet gas limit to 200 million and trial changes to block production, transaction execution and gas accounting, including block-level access lists intended to support parallel processing. It will not increase mainnet capacity, and developers have not announced a mainnet activation date. The Glamsterdam upgrade is part of Ethereum’s scaling roadmap; its benefits will depend on validator performance and network demand, and could eventually support lower transaction fees.
ETH has rebounded from about $2,330 and recently traded around $2,450–$2,500, compared with roughly $2,400–$2,425 on October 18. Traders are watching resistance at $2,500–$2,550; a sustained break could put $2,600 and potentially $2,800 in view. If ETH fails to clear resistance, $2,400 and then $2,300 are key downside levels. The latest report also cites about $1.08 billion in cumulative Ethereum ETF withdrawals during October as a headwind. The Glamsterdam test may bolster confidence in Ethereum’s development progress, but the upgrade alone does not guarantee stronger ETH demand or a lasting price recovery.
Neutral
The development is structurally constructive for Ethereum, but its immediate price impact is limited because Glamsterdam is being tested on Hoodi and Sepolia, not activated on mainnet. A 200-million testnet gas limit and changes intended to improve block production and parallel transaction processing may strengthen confidence in Ethereum’s scaling roadmap. Over the longer term, successful implementation could increase network capacity and potentially reduce transaction costs, although the effect on ETH fee revenue and burning is uncertain.
In the short term, price action and demand indicators are likely to matter more than the testnet milestone. ETH has recovered from about $2,330, but resistance at $2,500–$2,550 remains important; a sustained break could encourage momentum buying toward $2,600 and possibly $2,800. Failure to break out could bring $2,400 and $2,300 back into focus. Reported October ETF outflows of about $1.08 billion may weigh on sentiment and offset optimism about the upgrade. As with prior roadmap milestones, traders may initially respond positively, but durable gains will depend on follow-through in mainnet progress, usage, capital flows and broader market conditions. These competing factors support a neutral overall assessment.
