Ethereum Price Forecast: What Could Glamsterdam Mean for ETH?

Author: CoinSense

Ethereum is trading just below the $2,500 resistance level as focus and forecasts turn firmly toward the network’s next major upgrade. The larger narrative is not the latest daily candle, but what is expected in October and whether traders have already factored it into the price.

Developers completed an important rehearsal for the Glamsterdam upgrade this week, with test blocks continuing to finalize under revised block-building rules ahead of the proposed October 6 launch on the Sepolia public testnet.

Nethermind’s client handled 570.7 billion gas across 2,302 tests in three minutes and 15 seconds, equal to 2.9 billion gas per second, while checking block-level access lists that allow nodes to retrieve data in advance rather than process it sequentially. Roughly an hour after launch, the testnet’s gas limit rose from 60 million to 200 million, boosting per-block capacity by nearly 3.3 times.

This is more than a surface-level adjustment. Assuming node operators can manage larger blocks, higher gas ceilings should reduce fee surges during periods of intense demand, such as token launches or cascading DeFi liquidations. So far, the market has responded with cautious optimism rather than excitement, creating a technical setup that deserves closer attention.

ETH’s rise to $2,495 keeps it within the consolidation range established in early September, with recent daily closes grouped between $2,446 and $2,488. Trading volume has been ordinary, showing neither capitulation nor a surge of aggressive buying—only steady accumulation.

The daily moving averages remain arranged bullishly (20 > 50 > 200), technically supporting further upside, but the price has failed to close above the $2,493–$2,508 resistance zone.

Holders are looking for a decisive break over $2,508, which could clear the way to $2,550 and then the $2,723–$2,822 supply area, confirming the broader $2,800 target discussed by analysts. If the market remains uncertain, trading may continue to oscillate between $2,440 and $2,508 while participants await firm Glamsterdam mainnet dates.

A decline below the $2,378–$2,403 support zone, however, would undermine the near-term structure and expose a route toward $2,300. For a more detailed look at these levels, see this Ethereum price outlook covering potential bullish breakouts.

LiquidChain Pursues Early-Mover Potential as Ethereum Tests Critical Levels

Holding ETH during this consolidation phase is not unreasonable. The fundamental argument for Glamsterdam is credible, and a 3.3-fold increase in the gas limit is the type of capacity improvement that generally matters over quarters rather than days. Still, the uncomfortable reality is that, given Ethereum’s size, even a successful upgrade cycle is more likely to produce double-digit percentage gains than the kind of multiples that transform a portfolio.

That limitation is precisely why traders willing to accept greater risk continue to watch earlier-stage infrastructure opportunities. This analysis of ETH supply dynamics and breakout requirements offers useful perspective on how a rally after the upgrade could play out in practice.

LiquidChain ($LIQUID) is a Layer 3 infrastructure initiative designed to combine Bitcoin, Ethereum, and Solana liquidity within a single execution environment. Its “deploy-once” architecture enables developers to build on one layer and access all three ecosystems without the complications of bridging.

The presale is currently priced at $0.014956, with $960K raised so far. Its Unified Liquidity Layer and Single-Step Execution model address the same fragmentation issue that has slowed cross-chain DeFi adoption for years.
