Ethereum Whales Accumulate 871,000 ETH in Single Day, Control 27% of Supply

Ethereum whales have been accumulating ETH at rates not seen since 2017, indicating potential market shifts and renewed investor confidence in the leading smart contract platform. Large wallets holding between 1,000 and 10,000 ETH have added over 871,000 ETH in a single day, marking the highest whale inflow this year and a significant uptick in accumulation activity. These whales now control 27% of Ethereum’s circulating supply, a level of concentration that historically precedes major price movements.

In June 2025, Ethereum witnessed an unprecedented surge in whale activity, with wallets holding substantial ETH balances increasing their holdings dramatically. This accumulation, the largest since the 2017 bull run, indicates a strategic repositioning by major investors. Over the past week, daily inflows from these whales have consistently exceeded 800,000 ETH, pushing their total holdings beyond 14.3 million ETH. This concentration now represents approximately 27% of Ethereum’s total supply, underscoring the growing influence of large holders on market dynamics.

Despite this significant accumulation, Ethereum’s price has remained relatively stable, hovering around the $2,548 mark and encountering resistance near $2,700. Technical analysis reveals a sideways trading pattern since early May, with the Relative Strength Index (RSI) at a neutral 54, suggesting a balance between bullish and bearish forces. However, the persistent buying pressure from whales contrasts with the broader market’s indecision, potentially signaling an impending breakout. Analysts suggest that these investors may be positioning ahead of anticipated network upgrades and increased institutional adoption, which could catalyze future price appreciation.

Beyond accumulation, Ethereum’s ecosystem continues to expand robustly. Staking activity has reached new heights, with over 35 million ETH locked in staking contracts, reflecting strong long-term commitment from holders. Additionally, accumulation addresses—wallets that have not sold their ETH—have hit an all-time high of 22.8 million ETH. Layer 2 solutions like Arbitrum and Optimism are experiencing surges in USDC transfers, while Ethereum Name Service (ENS) whale transactions increased by over 300% in early June. Lending protocols also report a significant rise in whale participation, indicating diversified engagement across the network.

Market observers attribute the whale accumulation trend to strategic positioning ahead of key Ethereum ecosystem milestones. Upcoming protocol upgrades aimed at scalability and efficiency improvements, coupled with growing institutional interest in decentralized finance (DeFi) and real-world asset tokenization, are likely driving this buying behavior. Glassnode’s data highlights that such accumulation patterns have historically preceded bullish market phases, reinforcing the narrative that whales anticipate positive developments in Ethereum’s trajectory.

The recent surge in Ethereum whale accumulation marks a pivotal moment for the network, reflecting renewed confidence among large investors despite current price stagnation. With whales controlling a significant portion of the supply and ecosystem metrics trending positively, Ethereum appears poised for potential growth. While the market remains cautious, these developments suggest that strategic positioning is underway, setting the stage for possible upward momentum as key upgrades and adoption milestones approach.
