Ethereum (CRYPTO:ETH) developers have announced that the Glamsterdam upgrade is set to activate on the Sepolia testnet on October 6, 2026. While this test network is used for experiments where the tokens hold no real value, the timeline for the main network launch remains uncertain. As the Glamsterdam upgrade gears up for testing, many ETH holders are left wondering if this rehearsal can positively affect the coin’s price.

Currently, ETH is trading at $2,706 as of October 1, which is about 45% lower than its peak of $4,946 on August 24, 2025. With this scheduled upgrade, ETH buyers are questioning whether they should expect an increase in price or if traders are simply interpreting the developer schedule as a signal to buy.

The Glamsterdam upgrade is a hard fork, meaning it represents a major change to the software that every node—every computer running Ethereum’s software—must adopt simultaneously. If any node chooses not to implement this upgrade, it will stop following the main Ethereum chain. Consequently, developers first test each fork on networks like Sepolia, where no actual user funds are at risk.

The Sepolia test also includes a gas limit target of 200 million. Gas measures the computational effort required for transactions, while the gas limit determines how much can fit into a single block. Increasing the gas limit can allow more transactions per block, which could lead to lower fees when network activity is high.

However, the upgrade schedule has been delayed in the past, and developers will announce a mainnet date only after the test run completes successfully. Therefore, while October 6 marks an important date for testing, it does not signify a mainnet launch.

Traders Have Watched Glamsterdam for Months, So the Test Date Adds Little

Ethereum developers plan their upgrades through public forums and release details well in advance, making it easy for traders to stay informed. By the time the testnet goes live, interested traders have likely already adjusted their positions.

In September, ETH experienced fluctuations even before any code related to Glamsterdam was activated. The coin traded between $2,355 and $2,807 throughout the month as the crypto market began to recover from three consecutive quarters of losses. A trader who invested $1,000 in ETH at its September low would now have about $1,149 at $2,706—this gain reflects broader market trends rather than the expected impact of the upgrade.

ETH Needs Users and New Money After Mainnet Before Glamsterdam Moves Its Price

Overlaid on the right side of the image are several glowing, interconnected hexagonal icons. The central hexagon prominently displays 'ETF' with 'Exchange Traded Funds' below it. Other hexagons contain symbols like a dollar sign, a hand holding money, an upward-trending bar chart, a circular arrow with a dollar bill, a lightbulb with a checkmark, and a 45% dial.

Any meaningful price movement from the Glamsterdam upgrade will depend on the mainnet launch and subsequent user engagement. First, applications and users must utilize the expanded block space, followed by lower fees reaching everyday users. Finally, new buyers will need to enter the market as the network becomes increasingly functional.

It’s important to note that a spike in transaction volume may not necessarily indicate genuine user interest. Increased activity could be driven by automated trading bots and spam, clouding the real picture until data can distinguish genuine users from bots. Additionally, much ETH buying occurs on exchanges or through spot Ether ETFs, making it easier to track demand through fund flows than by relying solely on chain activity.

Will the Glamsterdam Upgrade Move ETH’s Price?

In summary, the activation of the Glamsterdam upgrade on the Sepolia testnet on October 6 is unlikely to have a lasting impact on ETH’s price. The test takes place on a network where coins have no real value, the date for the mainnet has not yet been set, and traders have been monitoring Glamsterdam closely for months.

However, there is an inherent risk: if the Sepolia test faces issues, it could delay the mainnet launch further.

If developers confirm a solid mainnet date after a successful test, the Glamsterdam upgrade could become a significant event that affects real stakes. If ETH were to rise above $2,807—a roughly 4% increase—and maintain that level with consistent ETF inflows post-mainnet, it could signal a new wave of interest driven by the improved utility of the network.
