Ethereum's Glamsterdam upgrade went live on the Sepolia test network on Tuesday at 1:53 pm UTC. Pooja Ranjan, an Ethereum community contributor, announced the activation in a post on X. Cointelegraph reported it in an article published Oct 6, 2026.
Sepolia is a test network, not the main Ethereum chain. This activation is one of the last major test runs before Glamsterdam goes live on mainnet. The upgrade is meant to make the Ethereum mainnet more efficient and more scalable.
The report gives no date for the mainnet activation. It also does not list the specific changes in Glamsterdam or say how the Sepolia launch has performed since it went live.
For anyone already holding an ETH perpetual position on Bitget, Bybit, MEXC or OKX, this changes nothing directly. A testnet activation does not change funding rates, trading fees or order-book liquidity on these exchanges, and the report does not mention any of them. The mainnet activation is a separate event, and no date has been given for it yet.
