Ethereum Glamsterdam Upgrade Targets Hoodi Testnet
Ethereum’s Glamsterdam upgrade is scheduled to activate on the Hoodi testnet on October 26 at 17:42:48 UTC, at epoch 132,352 and slot 4,235,264. At activation, Hoodi’s gas limit will rise to 200 million. The upgrade follows its October 6 rollout on Sepolia and includes enshrined proposer-builder separation (ePBS), block-level access lists to support parallel processing and validation, and revised gas accounting for state creation and access. Hoodi validators and node operators will need compatible execution and consensus clients. The 200-million gas limit is a testnet milestone, not a confirmed increase to Ethereum mainnet capacity; no mainnet activation date has been announced. For ETH traders, the Glamsterdam test is a technical development to monitor, but its testnet status limits the immediate case for a major price reaction. Watch for test results, bug reports and a confirmed mainnet timeline.
Neutral
The Hoodi activation is a meaningful technical milestone for Ethereum, but it remains a testnet deployment and does not establish when or how the upgrade will affect mainnet capacity. The 200-million gas limit applies to Hoodi, so it should not be read as an immediate increase in Ethereum transaction capacity or a direct change to ETH’s near-term fundamentals. In the short term, traders may respond to test outcomes, client readiness or bug reports, but absent a mainnet date or a confirmed change in network usage, the announcement alone offers limited grounds for a sustained price move. Over the longer term, successful testing of ePBS, block-level access lists and revised gas accounting could support expectations for improved execution and scalability. However, those potential benefits depend on successful testing and eventual mainnet implementation, so the likely price effect remains uncertain rather than clearly bullish or bearish.
