Ethereum activates Glamsterdam on Sepolia testnet: Why the price is falling anyway

Ethereum (ETH) has reached a key milestone in its next major network upgrade. The planned changes aim to improve Ethereum’s Layer 1 capacity and efficiency as network activity grows. The development comes as ETH retreats toward $2,500, highlighting the contrast between the network’s long-term technical progress and its short-term market weakness.

Ethereum developers successfully activated the Glamsterdam upgrade on the Sepolia testnet on Tuesday, testing and validating code changes – aimed at increasing the network’s ability to process more transactions – before a potential mainnet launch in the fourth quarter.

This milestone did not make huge headlines in the crypto market; in fact, ETH has corrected over 8% so far this week, trading around $2,500 on Friday.

But for people who follow ETH’s development closely, it is a meaningful step forward. Glamsterdam is the next major protocol upgrade after Fusaka (back on December 3, 2025) and advances the network’s Layer 1 scaling roadmap.

What’s Glamsterdam, and why does it matter?

The Glamsterdam name combines two parts: “Amsterdam” for the execution-layer changes and “Gloas” for the consensus-layer changes, which aim to improve Ethereum’s base layer performance as activity grows, continuing the network’s efforts to scale efficiently.

According to the Ethereum.org post, this upgrade centers on three main goals: speeding up processing (parallelization), expanding capacity, and preventing database bloat (sustainability). In short, Glamsterdam will introduce structural changes to ensure that as the network increases capacity, it remains sustainable and operates efficiently.

Moreover, Glamsterdam is one of those upgrades that doesn’t change what users or traders see day to day, but strengthens the foundation underneath everything else.

The smooth activation on Sepolia is encouraging, with client teams, node operators, and developers now having a real live environment to test against. If Glamsterdam continues to run smoothly on Sepolia without hiccups, developers will determine the timing of the next activation on the Hoodi network before considering the mainnet launch. After Glamsterdam’s mainnet deployment, the Hegotá upgrade is expected to follow, but the date is not yet confirmed.

Ethereum’s Hegotá upgrade is still in early planning, with Fork-Choice enforced Inclusion Lists (FOCIL) and frame transactions as the two next changes so far; dozens more have been proposed, and none are settled as per the roadmap.

Upgrades like this rarely attract much attention, and they don’t bring a sudden price spike or flashy new feature for users and traders. Instead, they matter for maintaining the network’s long-term competitiveness and resilience.

For now, the successful Sepolia activation is a solid green light and shows tangible progress in the second-largest cryptocurrency’s long-term vision of a scalable, sustainable base layer.

Ethereum faces macroeconomic headwinds despite strong Q3

Ethereum price action remains weak so far this week, pulling back around $2,500 on Friday after three consecutive months of gains and its strongest Q3 performance since 2016. 

While its improving network fundamentals support the long-term outlook, macroeconomic and geopolitical headwinds continue to weigh on its upside momentum.

A stronger US Dollar (USD) and elevated 10-year US Treasury yields are weighing on risk appetite, as higher yields make traditional fixed-income assets more attractive than risky assets such as cryptos.

Adding to this bearish outlook, the Federal Open Market Committee (FOMC) Minutes of the September 15–16 meeting showed that policymakers unanimously supported raising the federal funds rate target range by 25 basis points, to the 3.75%-4.0% range. Most officials expect that another interest rate increase would likely be appropriate by year-end to combat persistent inflation. This hawkish stance could further support US bond yields and the USD while capping cryptos.

Investors also remain worried about inflation risks stemming from volatile energy prices amid the US-Iran standoff over Tehran’s nuclear program, escalating Middle East conflicts, and disruptions around the Strait of Hormuz, further dampening risk appetite.

Looking ahead

If these macroeconomic developments continue to fuel higher Treasury yields and a stronger Greenback, they could keep pressure on ETH and limit its upside.

Therefore, while its long-term network evolution remains constructive, a sustained price recovery for the second-largest digital asset will likely require improved liquidity and favorable macroeconomic conditions.
