Since its inception in 2015, Ethereum has experienced a remarkable evolution, marked by 19 network upgrades and hard forks that have transformed it from a mining-based smart contract platform into a scalable proof-of-stake network. The upcoming Glamsterdam hard fork is set to target the mainnet by mid-2026, raising questions about whether this will represent Ethereum’s next significant milestone.
Historically, Ethereum prices have shown minimal immediate reactions to network upgrades, often taking months for the market to fully appreciate the implications. For instance, following the Pectra upgrade in May 2025, ETH eventually soared from $1,800 to nearly $4,946 within three months. This trend raises anticipation for Glamsterdam, which is shaping up to be one of the most ambitious upgrades in Ethereum’s history, tackling some of its most pressing long-term issues: high transaction fees, sluggish processing speeds, and dependence on external infrastructure.
Unlike its predecessors, such as the Pectra and Fusaka upgrades that primarily emphasized Layer 2 scaling solutions, Glamsterdam refocuses attention on the core Layer 1 network. While these earlier upgrades expanded the Ethereum ecosystem, the base chain still wrestled with issues of congestion and inefficiency. Glamsterdam aims to remedy this through two critical proposals: EIP-7732 (Enshrined Proposer-Builder Separation, or ePBS) for the consensus layer, and EIP-7928 (Block-Level Access Lists) for the execution layer. The ePBS proposal seeks to integrate block-building into Ethereum’s protocol, minimizing reliance on external middleware, thus enhancing transparency and decentralization while reducing censorship risks.
The Block-Level Access Lists promise to be the standout feature of the Glamsterdam upgrade. Traditionally, Ethereum processes transactions sequentially within blocks, leading to congestion during peak usage times. BALs introduce the ability for blocks to declare what data they will require ahead of time, enabling parallel execution without compromising security and potentially elevating the network’s capacity to handle 10,000 transactions per second—a dramatic leap from its current limits.
The Ethereum Foundation confirmed that Glamsterdam devnets are now operational, keeping the mainnet launch on schedule. Should the upgrade prove successful at scale, it could significantly increase Ethereum’s efficiency and speed, attracting considerable attention from investors and users alike.
Predicting Ethereum’s price movements post-upgrade is complex. Historical patterns indicate that while upgrades rarely lead to immediate price surges, sustained improvements may gradually increase ETH’s value. Forecasting various scenarios yields the following estimates for the price of 1 ETH:
-
Bull Forecast: $4,000 – $5,000
In an optimistic view, Glamsterdam could rejuvenate on-chain activity without disrupting the burn mechanism that limits supply. Reduced fees—projected to fall by approximately 78%—could rehabilitate user interest in the mainnet, while the implementation of ePBS and parallel execution enhances operational efficiency. This uptick in transaction volume might lead to Ethereum operating in a deflationary manner, enhancing long-term scarcity, and pushing ETH prices towards the $4,000 to $5,000 range over several months. -
Base Forecast: $2,500 – $3,300
This scenario assumes that while Glamsterdam operates as planned, there won’t be a drastic structural change in market dynamics. Fees would decrease, throughput would improve, and user experience would enhance, but demand may primarily remain concentrated on Layer 2 solutions and competing networks. Hence, ETH price might gradually rise to between $2,500 and $3,300, reflecting a 19% to 57% increase. -
Bear Forecast: $1,800 – $2,200
This pessimistic view suggests that while Glamsterdam may enhance performance on paper, it might not attract substantial new demand for Layer 1 space, resulting in users continuing to favor Layer 2 or alternative chains. Consequently, ETH could hover around $2,200 or even dip back to $1,800, indicating a lack of growth momentum.
In conclusion, the most probable price range for Ethereum following the Glamsterdam upgrade appears to be between $2,500 and $3,300, with potential for further growth towards the $4,000 to $5,000 bracket if the upgrade effectively drives activity back into Layer 1. However, history suggests that the full impact of such technological enhancements may take time to manifest, making immediate price movements unlikely as the market digests the changes.
