Ethereum accumulation addresses — wallets that rarely move coins — took in a record 1.14 million ETH in a single day back in November 2025, according to on-chain data. The milestone underscores a broader trend of long-term holders stacking supply, even as daily inflows have since settled to a more modest pace.
Record daily inflow
The 1.14 million ETH figure marked the highest single-day inflow into accumulation addresses on record. By comparison, average daily inflows in 2026 have run at about 200,000 ETH per day, suggesting the November spike was an outlier — possibly tied to a market event or a large whale moving funds into cold storage.
Mid-sized whales accumulate
Wallets holding between 10,000 and 100,000 ETH were particularly active during the period covered in an Oct. 14, 2025 report, accumulating 5.6 million ETH. That cohort — often called mid-sized whales — has been a key driver of the accumulation trend, steadily adding to positions rather than selling into rallies.
Total balance climbs
The total balance held in accumulation wallets rose by 6.5 million ETH to 26.55 million ETH from 20.1 million ETH on Jan. 1. The increase represents a roughly 32% gain in the supply held by these addresses, which are typically associated with long-term investors and institutional custodians.
Staked ETH hits new peak
Separately, the amount of ETH staked on the Beacon Chain reached a record 37.85 million, according to Dune data cited in a March 2026 Cointelegraph article. That figure represents about 31% of the circulating supply, reflecting growing demand for yield from staking as the network's proof-of-stake model matures.
The accumulation and staking trends point to a supply squeeze: more ETH is being locked up in long-term wallets or staking contracts, reducing the amount available for trading. Whether that dynamic will support prices depends on demand, but the data shows holders are increasingly reluctant to sell.
