Tom Lee's BitMine Nears 5% of Ethereum Supply With $11B Treasury Stash

BitMine Crosses 4.8% of Ethereum Ownership

BitMine Immersion Technologies has pushed its Ethereum treasury past 5.82 million ETH, worth roughly $11 billion at current prices, giving the Nasdaq-listed miner 4.8% of Ethereum’s total circulating supply. The company disclosed the position in an August 17 press release, cementing its status as the single largest known corporate holder of ETH and putting Tom Lee’s stated 5% ownership target within striking distance. The gap is now about 226,000 ETH, or less than $500 million at current prices.

Shares of BMNR climbed on the news as investors digested the fact that its treasury is now larger than the market caps of many mid-tier public miners. For context on where broader crypto prices sit while these accumulation numbers scale, ETH is trading near $1,900, a level that has held for most of August.

Fifty-Eight Straight Weeks of ETH Buying

BitMine has bought Ethereum every single week since launching its treasury strategy on June 30, 2025, according to filings tracked by CoinDesk. That is 58 consecutive weekly purchases across an ETH price range that fell from nearly $5,000 in August 2025 to under $2,000 by mid-2026. The streak did not pause during the drawdown, which is what has allowed the company to compound its position at cost bases well below the year-ago peak.

The most recent addition, roughly 9,926 ETH bought in the week ending August 16, was worth about $19 million and pushed the total from 5.81 million to 5.82 million tokens.

Inside the $11 Billion Ethereum Treasury

The disclosed breakdown, released by the company through PRNewswire, puts BitMine’s total crypto and cash holdings at $11.4 billion. The ETH stack alone accounts for the bulk of that number. Of the 5.82 million ETH on the books, more than 5.06 million tokens, or roughly 87% of the position, are actively staked on the network.

Staking those tokens matters for two reasons. It generates a running yield that offsets the operating cost of the treasury strategy and removes a large block of ETH from short-term trading circulation, thereby tightening the available float. Investors looking to buy ETH on exchanges are effectively competing for a shrinking pool of freely tradable supply as more supply moves into long-term institutional wallets.

What a Crypto Treasury Company Actually Does

A crypto treasury company is a listed business whose primary balance-sheet asset is a cryptocurrency rather than cash, inventory, or property. Instead of parking spare capital in short-term Treasuries or bonds, the company issues equity, debt, or convertible notes and uses the proceeds to buy and hold a specific token.

The playbook was popularised on the Bitcoin side by Michael Saylor’s Strategy, which has spent five years converting corporate cash and capital raises into BTC. BitMine is one of a growing group applying the same logic to Ethereum, betting that the token’s programmable settlement layer and staking yield make it a productive reserve asset. For a beginner, the key point is that shareholders in a treasury company effectively own leveraged, listed exposure to the underlying token without needing their own wallet or exchange account.

Staking Turns the Treasury Into a $250 Million Yield Engine

At current Ethereum staking rates, the 5.06 million staked ETH generates an estimated $250 million a year in native rewards, per figures cited by Decrypt. If BitMine were to stake its full position, that annual yield could climb to roughly $287 million.

Those numbers turn Ethereum from a static holding into a productive one, creating a different economic model than any Bitcoin treasury company. Retail investors chasing similar mechanics through crypto rewards programs or on-chain staking pools are participating in the same underlying dynamic on a smaller scale.

The Final Push to 5% Could Move Markets

If BitMine holds its weekly pace of roughly $19 million to $100 million in purchases, the remaining 226,000 ETH could be absorbed within weeks, not months. Any acceleration, such as an equity raise or convertible-note issuance directed at ETH accumulation, could compress that window further.

Analysts note that a single named buyer approaching a 5% supply share may draw regulatory attention, particularly around disclosure and market-concentration rules. It could also embolden other listed firms to formalise Ethereum treasury strategies of their own, which would compound the float-tightening effect. None of this is guaranteed, but the setup suggests that ETH’s institutional bid may remain a distinct component of the market through the rest of the year. For readers tracking the wider picture, the crypto news today beat is increasingly dominated by treasury-strategy disclosures rather than by pure spot-trading flows.

Ethereum’s Institutional Chapter Enters a New Phase

BitMine’s arrival at 4.8% of supply marks the point at which corporate treasury demand for Ethereum stops being a curiosity and starts being a market-structure feature. A publicly listed miner, once a proxy for Bitcoin block-reward economics, is now the single largest visible holder of ETH outside of exchanges and staking service providers.

Whether that concentration proves stabilising or destabilising will depend on how BitMine funds the final push, how the market absorbs a potential 5%-owner disclosure, and how quickly other listed firms follow with treasuries of their own. What is already clear is that Ethereum’s ownership base is being rewritten in public, one weekly filing at a time, and the next few filings are likely to be the most consequential yet.
