Ethereum is showing resilience in early September, with ETH holding around the $2,400–$2,450 range despite renewed pressure across broader risk assets.
The move follows a strong August recovery that lifted ETH from roughly $1,900 to above $2,500. Momentum has since cooled, with sellers continuing to defend the $2,500–$2,550 area.
At the same time, macroeconomic uncertainty is putting additional pressure on cryptocurrencies. Higher oil prices, rising Treasury yields and renewed geopolitical tensions have contributed to a broader risk-off environment.
Despite the pullback, ETH remains well above its levels from earlier in the summer.
$2,400 Becomes a Key Support Level
ETH is trading near the $2,400 area, making the level an important test for the September market.
Ethereum's August rally established stronger bullish momentum, but the failure to sustain a move above $2,500 has brought short-term consolidation back into focus.
If buyers continue defending $2,400, ETH could attempt another move toward $2,500. A decisive break above the $2,500–$2,550 resistance zone would provide a stronger bullish signal.
Conversely, losing $2,400 could increase the risk of a deeper correction toward lower support levels established during the August recovery.
Glamsterdam Upgrade Heads Toward Sepolia Testing
While price remains the immediate focus for traders, Ethereum's development roadmap is approaching an important milestone.
The upcoming Glamsterdam upgrade is scheduled for activation on Ethereum's Sepolia testnet on September 28, 2026, at 14:44:48 UTC.
The testnet fork will allow Ethereum developers, client teams and node operators to evaluate the upgrade in a live testing environment before a potential mainnet deployment.
A successful activation would provide an important indication that development work is progressing toward the next stage of Ethereum's roadmap.
Why Glamsterdam Matters for Ethereum
Ethereum's development roadmap increasingly focuses on improving scalability, execution capacity and network efficiency while preserving decentralization.
That makes major upgrades important not only for Ethereum's base layer but also for the wider ecosystem of applications and Layer-2 networks built around it.
A successful testnet deployment could therefore be closely watched by:
The Sepolia activation is not a mainnet launch, but it represents an important step in the upgrade process.
Layer 2 Remains Central to Ethereum's Growth
Ethereum's scaling strategy continues to rely heavily on Layer-2 networks.
These networks process transactions away from Ethereum's base layer while ultimately using Ethereum for settlement and security. This approach allows the ecosystem to support significantly more activity without requiring every transaction to be processed directly on the mainnet.
As Ethereum's base layer evolves, improvements to execution capacity and network efficiency could also benefit the broader Layer-2 ecosystem.
That makes upgrades such as Glamsterdam important beyond Ethereum itself.
Macro Conditions Remain a Short-Term Risk
Ethereum's price action is also being influenced by broader financial-market conditions.
Rising oil prices and higher US Treasury yields can weigh on risk-sensitive assets by tightening financial conditions and increasing the relative appeal of traditional fixed-income investments.
Cryptocurrencies have historically remained sensitive to changes in liquidity, interest-rate expectations and broader investor risk appetite.
For ETH, this means the upcoming Glamsterdam milestone could provide a fundamental catalyst, but broader market conditions will continue to influence short-term price action.
$2,500–$2,550 Remains the Key Resistance Zone
From a technical perspective, traders are likely to watch two areas closely.
Support: $2,400
Resistance: $2,500–$2,550
Holding above $2,400 would help preserve Ethereum's recent recovery structure. A sustained move above $2,550 could strengthen the bullish outlook and bring higher September levels into focus.
On the other hand, a decisive move below $2,400 could signal that the August recovery is losing momentum.
What to Watch in September
ETH Around $2,400
Ethereum's ability to defend this area could determine the next short-term direction.
$2,500–$2,550 Resistance
A sustained breakout above this zone would strengthen the bullish structure.
September 28 Sepolia Activation
The Glamsterdam testnet fork will be one of Ethereum's most important development milestones this month.
Layer-2 Activity
Continued growth across Ethereum's Layer-2 ecosystem remains important for long-term adoption.
Macro Liquidity
Treasury yields, oil prices, monetary-policy expectations and broader risk sentiment could continue influencing ETH.
Bottom Line
Ethereum enters September with a mixed but closely watched setup.
ETH remains above $2,400 after pulling back from the $2,500-plus levels reached during August, while broader macroeconomic pressure continues to limit short-term upside.
At the same time, Ethereum's fundamental development story remains active.
The Glamsterdam upgrade is scheduled to reach Sepolia on September 28, giving developers and the wider Ethereum ecosystem an important opportunity to test the next stage of the network's roadmap.
For traders, $2,400 remains the key near-term support, while $2,500–$2,550 represents the major resistance zone.
If ETH can maintain its recovery structure while Glamsterdam testing progresses smoothly, Ethereum could enter the next phase of September with both technical momentum and network development in focus.
