BitMine Lifts Ethereum Holdings to 5.85M ETH, Roughly 4.8% of Total Supply

BitMine has emerged as one of the largest single corporate holders of ether, reporting that it now controls close to one out of every 20 ETH in circulation—and has locked up most of it through staking. In its latest update, the company said it added 32,447 ETH over the past week, taking total holdings to 5,847,611 ETH as of Aug. 23, according to the original report. The stash equals about 4.8% of Ethereum's total supply. The more market-relevant detail is how much of that position is effectively illiquid. BitMine reported 5,067,309 ETH staked, or roughly 87% of its holdings, with projected annualized staking revenue of around $330 million. For context, it listed $308 million in cash and marketable securities. A staking book expected to generate more annualized revenue than the company's cash and securities highlights a balance-sheet strategy tied directly to validator economics. For traders, the key question is not only how much ETH BitMine owns, but how much could realistically come to market in a liquidity event given unstaking delays and Ethereum's exit mechanics. BitMine said total crypto, cash, securities and other investments stood at $14.9 billion. While ETH is not the entire balance sheet, it is the largest disclosed component of the strategy. A 4.8% share of supply is large enough to influence liquidity assumptions even without any stated intent to sell, and the high staking ratio may be read as a long-duration posture. The projected $330 million run-rate depends on prevailing Ethereum staking yields and the amount staked. Shifts in yield, validator penalties, or a congested exit queue would affect how quickly the position could be resized. The disclosure lands as Ethereum continues to lead builder activity among major networks, as tracked in "Top 10 Blockchains by Developer Activity This Week," while ownership concentration becomes a separate focus. Developers keep shipping, and large treasuries keep absorbing supply. BitMine's approach also reflects a broader institutional shift toward treating onchain assets as balance-sheet holdings rather than short-term trading inventory. Tokenized real-world assets recently surpassed $20 billion onchain, covered in the "Weekly Tokenization Roundup." Institutional staking demand has also been visible across layer-1 networks, including the capital flows linked to Sui's recent price surge. Staking revenue gives equity analysts an income stream to model, potentially making BitMine's financial profile easier for institutions to evaluate. At the same time, it ties earnings to Ethereum network conditions: a sustained drop in staking yield or a lengthy validator exit queue could pressure cash-flow expectations without changing the token count. Policy risk remains a backdrop for any entity holding and staking 4.8% of ETH supply. Washington's digital-asset debate was still unresolved this month, with banks pushing back on major crypto legislation ahead of a Senate vote. If rules around staking and custody change, large treasury operators may face new compliance decisions about where and how staking is conducted. BitMine did not detail its validator arrangements, whether staking is run in-house or via third parties, or how staking revenue is recognized across jurisdictions. Investors should treat the $330 million projection as a snapshot based on current conditions rather than guaranteed cash flow. Whether the accumulation pace continues remains to be seen, but the 87% staking ratio already signals how little of BitMine's ETH is positioned for near-term liquidity.
