Tom Lee’s Bitmine has staked about $508 million worth of Ethereum in a recent move tracked by Arkham.
The transfers were routed through institutional channels, adding to the firm’s ongoing staking strategy.
The latest activity comes as Bitmine continues to increase its exposure to Ethereum. On-chain data shows the firm has now staked more than 4 million ETH, valued at about $9.3 billion, representing around 10.5% of total staked supply.
Recent disclosures show Bitmine’s total Ethereum holdings have crossed 5 million ETH. The company reported holdings of about 5.07 million ETH, marking a key milestone in its accumulation strategy.
Chairman Tom Lee said, “Bitmine ETH holdings crossed 5 million this past week,” noting the pace of accumulation has been rapid.
The firm now holds more than 4% of the total ETH supply. This places Bitmine among the largest institutional holders of Ethereum in the market.
Bitmine has focused on staking a large share of its ETH holdings. More than 4 million ETH is already deployed in staking programs, generating yield while reducing liquid supply.
The company’s broader plan targets holding a larger share of Ethereum supply. Reports indicate a strategy aimed at securing up to 5% of total ETH over time through continued purchases and staking.
This approach combines accumulation with yield generation. Staked ETH contributes to validator activity while producing ongoing rewards tied to network participation.
Bitmine’s growing position has drawn attention to staking concentration. Large allocations of ETH in staking reduce available supply on the open market and increase the role of institutional participants.
The company has expanded its holdings steadily in recent months. Earlier filings showed ETH holdings around 4.5 million tokens before the recent increase past 5 million.
