Ethereum whales boost accumulation as ETH sits near $2,100

Ethereum’s price lingered around $2,091 on May 24, a 57% drop from its August 2025 high of $4,946, while whales accumulated a record 26.55 million ETH this year—up 32% since January 2026【1】.

The surge in on‑chain accumulation comes as roughly 30% of all circulating ETH remains staked, tightening liquid supply despite the price weakness. Analysts point to three concurrent forces that could close the gap between fundamentals and market value. First, the upcoming “Glamsterdam” execution‑layer upgrade, slated for June 2026 (with a possible slip to Q3), promises to slash gas fees by 78.6% and boost throughput to 10,000 transactions per second【1】. Past upgrades, such as the Merge and the 2025 Pectra upgrade, have historically sparked price rallies in the weeks after launch, suggesting a similar catalyst effect if Glamsterdam rolls out on schedule.

Second, spot Ethereum ETFs have attracted $187 million in a single week, pushing cumulative net inflows to $12.05 billion for 2026【1】. This inflow, combined with the record whale accumulation, signals strong institutional positioning that the current price does not yet reflect. Third, BlackRock’s pending filing for a staked ETH ETF (ETHB) could open a new avenue for retail and institutional investors to capture staking yields directly, potentially adding billions of dollars of demand if approved【1】.

Price forecasts remain divided. Citi’s near‑term target of $3,175 sits in a “base case” where Glamsterdam launches without a sharp price reaction, keeping ETH in a $3,000‑$4,200 range through year‑end【1】. Standard Chartered’s bullish outlook of $5,000‑$7,500 hinges on a timely upgrade, accelerated ETF inflows, and a Bitcoin rally above $90,000【1】. Conversely, a delayed or buggy Glamsterdam rollout could push ETH back into a bear scenario, testing the February low of $1,743 and ending the year near today’s level【1】.

The real question is whether the confluence of a major protocol upgrade, growing ETF inflows, and unprecedented whale accumulation can translate into a price breakout toward the $4,000 mark before the year closes, or if delays will defer that momentum into 2027.
