BitMine has expanded its Ethereum holdings again, acquiring 9,926 ETH over the past week as the company continues to build one of the largest corporate cryptocurrency positions in the market. The company behind the buildup, BitMine Immersion Technologies (ticker: BMNR), began as a Bitcoin mining and hosting business before pivoting to an Ethereum-focused treasury strategy in 2025, a shift that turned a small mining operator into one of the most significant corporate holders of a single digital asset.

The latest purchase brings BitMine's total Ethereum holdings to 5,815,164 ETH, representing approximately 4.8% of Ethereum's total supply. The company is also putting a substantial portion of that ETH to work: BitMine said 5,067,309 ETH is staked, equivalent to roughly 87% of its total holdings.

The update was highlighted by @WuBlockchain on X, drawing fresh attention to BitMine's Ethereum accumulation strategy and its growing role as a major institutional holder of the asset.

Holdings Continue to Grow

The acquisition of 9,926 ETH adds to a rapidly expanding cryptocurrency treasury. At more than 5.8 million ETH, BitMine's holdings now represent a significant share of Ethereum's overall supply, making the company an increasingly important corporate participant in the Ethereum ecosystem.

Unlike traditional companies that primarily hold cash, bonds or other conventional financial assets, BitMine has adopted a strategy centered heavily on Ethereum, accumulating ETH while simultaneously staking a large percentage of its holdings. That approach gives the company exposure to changes in Ethereum's market value while also generating additional income through staking.

Nearly 87% of ETH Is Staked

BitMine reported that 5,067,309 ETH — approximately 87% of its total Ethereum holdings — is currently staked. Staking allows Ethereum holders to help secure the network by committing ETH to the blockchain's proof-of-stake system, with participants receiving staking rewards in return. Ethereum has operated on proof-of-stake since the Merge, the September 2022 upgrade that replaced energy-intensive proof-of-work mining — the mechanism Bitcoin still uses — with validator-based security.

At BitMine's scale, those rewards can become a meaningful source of recurring revenue. The company estimates its annualized staking revenue could reach approximately $250 million, illustrating why large-scale Ethereum accumulation carries a different economic profile from simply holding the asset. Rather than leaving its treasury idle, BitMine is seeking to generate additional returns from its cryptocurrency holdings.

A $250 Million Annualized Revenue Estimate

The projected $250 million in annualized staking revenue could become an important component of BitMine's financial strategy. Staking income can provide a recurring revenue stream as long as the underlying ETH remains staked and network conditions continue to support the expected reward rate.

The actual amount generated can fluctuate, however. Ethereum staking rewards are influenced by network activity, the total amount of ETH being staked and other factors, and the U.S. dollar value of those rewards can change significantly depending on ETH's price. BitMine's projected annualized figure should therefore be viewed as an estimate rather than a guaranteed amount. Even so, the decision to stake such a large portion of its holdings underscores the company's commitment to an Ethereum-focused treasury model.

Share Buybacks Continue

BitMine's strategy is not limited to cryptocurrency accumulation. The company also repurchased approximately 1.7 million shares during the latest week, bringing cumulative share repurchases since July to more than 20.8 million shares.

Share buybacks can reduce the number of outstanding shares and potentially increase the proportional ownership of remaining shareholders. For BitMine, the combination of Ethereum accumulation and stock repurchases represents two distinct approaches to capital allocation — increasing exposure to Ethereum while returning capital through purchases of its own shares. Investors will likely continue watching how the company balances those priorities as its cryptocurrency holdings expand.

Total Assets Reach $11.4 Billion

As of August 16, BitMine reported total crypto holdings, cash, marketable securities and other investments of approximately $11.4 billion, highlighting the scale of the company's overall balance sheet. Ethereum accounts for a significant portion of that value, reinforcing the importance of ETH to BitMine's corporate strategy.

BitMine has effectively positioned itself as a major public-market vehicle with substantial exposure to the Ethereum ecosystem. That model differs from traditional corporate treasury strategies, which often prioritize cash and low-risk securities. BitMine's approach carries greater exposure to cryptocurrency market volatility, but also potential upside if Ethereum appreciates over the long term.

Why BitMine Is Accumulating Ethereum

The company's strategy appears based on the view that Ethereum will remain an important part of the digital asset economy. Ethereum supports a large ecosystem of decentralized applications, stablecoins, tokenized assets and financial protocols, and its proof-of-stake system allows ETH holders to earn staking rewards. The accumulation strategy has also been closely identified with Tom Lee, the Fundstrat Global Advisors co-founder who chairs BitMine's advisory board, giving the company a high-profile Wall Street voice behind its Ethereum-focused approach.

For a company holding millions of ETH, even relatively modest staking yields can translate into substantial annual revenue, creating an investment model that combines potential asset appreciation with recurring blockchain-based income. BitMine's growing position could therefore reflect a longer-term strategy rather than a short-term trading decision.

Corporate Crypto Treasuries Are Expanding

BitMine's approach comes as more publicly traded companies explore cryptocurrency treasury strategies. Bitcoin has traditionally dominated the corporate crypto treasury market — a playbook pioneered at scale by Strategy, formerly MicroStrategy, whose purchases beginning in 2020 made it the largest corporate holder of that asset — but Ethereum is attracting increasing attention, with its staking capabilities offering one potential advantage for companies seeking more than passive exposure. A corporate treasury holding ETH can potentially participate in network rewards while maintaining exposure to the asset.

The strategy also comes with risks. Ethereum's price can experience significant volatility, and companies with large concentrations of ETH may see substantial changes in the value of their balance sheets, making treasury management particularly important.

The Scale of BitMine's Position

Holding approximately 4.8% of Ethereum's total supply places BitMine in a distinctive position. A single corporate entity controlling that much ETH can become an important participant in the broader ecosystem.

At the same time, the company's staking strategy means much of its ETH is committed to the network rather than held in liquid form, which could reduce the amount of ETH immediately available for sale while increasing potential staking income. The long-term implications will depend on how the company manages its holdings and whether it continues accumulating ETH at the current pace.

Ethereum Supply and Institutional Demand

BitMine's purchases also highlight the growing importance of institutional demand for Ethereum. As more companies seek exposure to digital assets, large purchases can become an increasingly important source of market demand.

Ethereum's supply dynamics are particularly relevant because the amount of ETH available on exchanges and in liquid markets can change as more coins are staked or used throughout the ecosystem. Large corporate holders could therefore become an increasingly visible part of Ethereum's market structure, and BitMine's growing position provides one example of how institutional treasury strategies could affect the cryptocurrency market.

What Comes Next for BitMine

BitMine's latest update shows the company continuing to pursue its Ethereum accumulation strategy. The acquisition of another 9,926 ETH brings holdings to more than 5.8 million ETH, with more than 5 million ETH already staked, while BitMine continues to repurchase its own shares and maintain a substantial portfolio of cash, marketable securities and other investments. Ethereum remains at the center of that approach.

The open question for investors is whether the strategy can continue delivering value as the company's ETH holdings grow. If Ethereum performs strongly, BitMine could benefit from both appreciation in its holdings and staking income; a prolonged downturn in the cryptocurrency market, however, could create significant balance-sheet pressure given the company's large ETH concentration.

For now, BitMine is betting heavily on Ethereum. With 5.82 million ETH under its control and nearly 87% of those holdings staked, the company has become one of the most significant corporate holders of the cryptocurrency. Its latest purchase suggests the accumulation strategy is continuing, while the projected $250 million in annualized staking revenue provides another reason for investors to watch BitMine's growing Ethereum treasury closely.
