KEY POINTS
- Ethereum is trading at $2,380, up from $1,800 in March, as developers finalize the Glamsterdam upgrade that will raise the gas limit 3.3x and enable parallel transaction execution.
- Spot Ethereum ETFs posted $61.3 million in net inflows on May 4, with BlackRock's ETHA contributing $54.8 million, extending a flow reversal that broke a five-month losing streak in April.
- The $2,400 level remains key resistance; a sustained break above it would target $2,800, while the Glamsterdam mainnet activation — expected within weeks — could serve as a fundamental catalyst.
Ethereum is trading at $2,380 on Tuesday, pressing against the $2,400 resistance level that has defined the upper boundary of its range for the past two weeks. The second-largest cryptocurrency has climbed more than 30% from its March low near $1,800, outperforming Bitcoin on a percentage basis over the past 30 days and drawing renewed attention from institutional allocators who had largely ignored ETH for most of the year.
The catalyst driving the repricing is not just the broader crypto rally. Ethereum's Glamsterdam upgrade, the network's most significant hard fork since Pectra last May, is approaching mainnet activation in the coming weeks. Core developers have aligned on the final specifications, and testnet deployment is running without critical issues. The upgrade introduces two architectural changes that address the network's most persistent criticism: that Layer 1 is too slow and too expensive for mainstream adoption.
What Glamsterdam Actually Changes
The first major component is Enshrined Proposer-Builder Separation, which restructures how blocks are constructed and validated. The second is Block-Level Access Lists, defined in EIP-7928, which specify in advance which storage slots and accounts a transaction will touch. Together, these changes enable parallel execution of transactions that do not share state dependencies — a fundamental shift from the current sequential processing model.
The practical result is a roughly 3.3x increase in L1 throughput. Ethereum core contributors have aligned on a post-Glamsterdam gas limit floor of 200 million, up from the current 60 million. That jump would push theoretical L1 capacity toward 10,000 transactions per second, a number that begins to compete with the throughput claims of alternative Layer 1 chains that have used Ethereum's slowness as a marketing pitch for years.
For DeFi protocols, the implications are significant. Higher throughput and lower base fees would reduce the cost of on-chain trading, lending, and yield farming on L1, potentially pulling activity back from Layer 2 rollups that captured volume during Ethereum's congestion era. Ethereum already posted a record-breaking Q1 with 200.4 million transactions, and the Glamsterdam upgrade could accelerate that trajectory.
ETF Flows Finally Turning
The institutional picture for Ethereum has improved materially. Spot ETH ETFs posted $61.3 million in net inflows on May 4, led by BlackRock's ETHA at $54.8 million and Fidelity's FETH at $6.5 million. That session extended a flow reversal that broke a five-month losing streak in April, when cumulative ETH ETF flows turned positive for the first time since November 2025.
The flow recovery is still modest compared to Bitcoin's ETF dominance. Cumulative net inflows into Ethereum ETFs remain a fraction of the $59.3 billion that Bitcoin funds have attracted. But the direction matters more than the magnitude at this stage. Ethereum ETF demand turning positive removes a persistent headwind that had weighed on ETH's relative performance for months.
The Trade Setup
Technically, $2,400 is the line in the sand. ETH has tested it four times since mid-April and been rejected each time. A sustained daily close above $2,400 would likely trigger a move toward $2,800, where the next significant supply zone sits based on on-chain cost-basis clustering. On the downside, $2,200 has held as support through three retests, and a break below it would target $2,000.
The institutional consensus for ETH by year-end ranges from $3,500 to $5,000, contingent on Bitcoin holding above $75,000 and the Glamsterdam upgrade delivering on its throughput promises. The next two weeks — when mainnet activation timing should crystallize — will determine whether that consensus looks conservative or optimistic.
