UAEEthereum Glamsterdam upgrade on Hoodi testnet
The Ethereum Foundation has scheduled the Glamsterdam upgrade to activate on the Hoodi testnet on October 26, 2026. The test network's gas limit will rise to 200 million, and the event concerns ETH.
What is happening
Glamsterdam is the next technical step on Ethereum's roadmap. On October 26 it is set to go live on Hoodi, a public test network, rather than on the main Ethereum network. As part of the activation, the testnet's gas limit will be raised to 200 million.
The upgrade covers three areas: block construction, parallel transaction processing and execution efficiency. Together these changes extend Ethereum's scaling roadmap, aiming to let the network handle more activity.
No mainnet activation date has been set. A successful testnet run is an intermediate milestone, and the sources do not say when or whether a mainnet rollout will follow.
Why it matters
For the network, a testnet deployment is where developers and node operators can observe how new changes behave before they reach real funds. Results on Hoodi are therefore a useful signal for the upgrade's readiness, even though the timeline for mainnet remains open.
For holders and traders, the event is mainly a development-progress marker rather than a direct financial trigger. Reporting around the event notes that a clean testnet run does not translate into an immediate financial return, and that the market backdrop remains cautious: ETH traded near $2,445 on October 19, and U.S. spot ETH ETFs recorded about $955 million in net outflows between October 1 and October 16. Any sustained recovery is described as depending on fund flows stabilizing and demand returning, rather than on a single technical milestone. Watch for the outcome of the Hoodi activation, any announcements about further test stages, and whether a mainnet date is eventually communicated.
