Why Is Bitmine Buying Back Shares Instead of More Ethereum?
Ethereum treasury companies have spent billions accumulating ETH, but Bitmine is taking a different approach as crypto markets face pressure. The company is directing capital toward share buybacks while continuing to expand its Ethereum holdings.
In an October 26, 2026, update, Tom Lee’s Bitmine Immersion Technologies reported approximately $14.3 billion in ETH holdings and nearly $400 million in share repurchases for the year.
The move raises a key question for Ethereum investors: why is Bitmine buying back its own shares instead of putting more capital into ETH, and what could this decision mean for shareholders?
Bitmine is pursuing two strategies at once: increasing its Ethereum holdings and buying back its publicly traded BMNR shares. The balance between these approaches has become more notable as the company moves closer to its goal of holding 5% of ETH’s total supply.
Its latest update shows how Bitmine is allocating capital and why management believes repurchasing BMNR shares could benefit shareholders.
Bitmine Buys $24.5 Million in ETH as BMNR Share Buybacks Near $400 Million
On October 26, 2026, Bitmine Immersion Technologies reported that it had purchased another 10,452 ETH, worth approximately $24.5 million at the time of its announcement. This brought its total holdings to 6,051,933 ETH, valued at about $14.3 billion using the company's reference price of $2,356 per ETH as of October 25. Bitmine's holdings represented approximately 4.95% of the 122.2 million ETH supply figure cited in its update.
The company also repurchased 2.04 million BMNR shares at an average price of $22.48, spending approximately $45.9 million during the week. That brought its total share repurchases for 2026 to 22.9 million shares, costing $399.6 million at an average price of $17.48.
The figures show that Bitmine has not stopped accumulating Ethereum. However, its latest buyback activity came after a roughly 10-week pause, making the decision to resume repurchases a notable part of its capital-allocation strategy.
Why Bitmine Believes Buying Back Its Shares Could Create Value
Bitmine Chairman Tom Lee said the company intends to repurchase shares when management believes they are relatively undervalued, subject to market conditions and its existing authorization. The aim is to improve shareholder value rather than direct all available capital toward buying more ETH.
The reasoning is straightforward: if a company buys back its shares at a price below their underlying value, the remaining shares may represent a larger claim on its assets. For Bitmine, that means comparing BMNR's stock-market valuation with the value of its Ethereum holdings, other assets, and liabilities.
However, buybacks alone do not prove that a stock is undervalued or guarantee gains for investors. The potential benefit depends on the price paid for the shares and how the company's overall financial position changes.
Bitmine’s share buybacks are only one part of its broader strategy. The company is also building one of the largest corporate Ethereum treasuries, with a goal of acquiring 5% of ETH’s total supply. Its latest holdings show how close it is to that target and how staking could help generate additional revenue from its ETH reserves.
Bitmine Holds Nearly 5% of Ethereum’s Total Supply
Bitmine reported holding over 6 million ETH as of October 25, 2026, representing approximately 4.95% of the total ETH supply of 122.2 million cited in its announcement. The company calls its goal the “Alchemy of 5%” and said it was 99% of the way toward reaching that target after 15 months of accumulation.
Reaching this milestone would give Bitmine a substantial position in Ethereum, but it would not guarantee higher ETH prices or stronger returns for shareholders. The dollar value of its treasury would still depend on ETH’s market price, while BMNR shares would also reflect how investors value the company and its overall financial position.
How Ethereum Staking Could Generate Revenue for Bitmine
Beyond accumulating ETH, Bitmine is staking a large portion of its holdings to earn rewards for helping support the Ethereum network. In its October 26 SEC filing, it was reported that 5,227,037 ETH, worth approximately $12.3 billion at the stated price of $2,356 per ETH, was staked. This represented about 86% of its total ETH holdings.
Based on this amount and its reported staking yield, Bitmine projected annualized staking revenue of approximately $318 million. This is an estimate based on current conditions, not a guarantee of future earnings. Staking rewards can change with yields and operating conditions, while ETH price declines can reduce the dollar value of both its holdings and rewards.
For Bitmine, staking offers a way to generate income while maintaining a large ETH position. However, it does not remove the risks of holding a concentrated crypto treasury or guarantee that the strategy will deliver higher shareholder returns.
For crypto treasury companies, deciding what to do with available capital involves more than choosing which cryptocurrency to buy. A company can use that money to expand its crypto holdings or repurchase its own shares, and the better choice depends on how the market values each option.
Understanding how buybacks work helps explain why Bitmine might see value in reducing its share count while continuing to accumulate ETH.
How Stock Buybacks Work and What They Mean for Shareholders
A stock buyback occurs when a company uses its money to repurchase shares from investors. If those shares are retired or held as treasury shares, the number of shares outstanding decreases, potentially increasing each remaining shareholder's proportional ownership of the company.
For example, suppose a company has 100 million shares outstanding and repurchases 10 million of them. If those shares are retired, each remaining share represents a larger ownership stake than before. However, this does not automatically increase the stock price, because the company has also spent money to buy those shares.
For a crypto treasury company, the key question is whether the repurchase price justifies that cost.
Why Buying Shares Below Net Asset Value Can Benefit Investors
Net asset value (NAV) is the value of a company's assets minus its liabilities. For a crypto treasury company, this calculation can include ETH or BTC holdings, cash, other investments, and outstanding debts.
Investors can compare a company's market value with its estimated NAV to see whether its shares trade at a premium or discount. Research from Galaxy Research explains how this comparison helps investors assess the market value of digital asset treasury companies relative to their underlying assets.
If a company repurchases shares for less than their underlying net asset value per share, the transaction can increase the net asset value attributable to each remaining share, assuming other factors remain unchanged. But a buyback does not prove that a stock is undervalued. The result depends on the price paid, the assets and liabilities involved, and how the company finances the purchase.
When Buying More ETH Could Be Better Than Buying Back Shares
The choice between buying ETH and repurchasing shares depends on which option offers better value for the company's capital. Buying more ETH increases its cryptocurrency holdings, but it also increases its exposure to ETH price movements. Buying back shares can benefit remaining shareholders if the company repurchases them at an attractive price relative to its underlying assets.
Bitmine’s October 26 announcement illustrates this balance. The company made additional ETH purchases while buying back its own shares during the same week. Rather than scaling back its Ethereum strategy, Bitmine is allocating capital toward two objectives: expanding its ETH holdings and reducing its outstanding share count.
Neither approach is automatically better. Buying ETH may make more sense when the company sees an attractive opportunity in Ethereum and has sufficient cash to manage its obligations. Buybacks may offer greater value when shares are priced below a reasonable estimate of the company's net assets.
For investors, the important question is not simply whether Bitmine buys more ETH or fewer shares. It is whether management's decisions improve the value attributable to each remaining share without creating unnecessary financial risk.
Bitmine is not the only crypto treasury company weighing share repurchases against further cryptocurrency purchases. Strategy, the largest corporate Bitcoin holder, has also directed capital toward buybacks while maintaining its crypto treasury.
Its approach shows why investors need to look beyond how much Bitcoin or Ethereum a company owns and examine how it manages its cash and financing.
Strategy’s Bitcoin Treasury Shows a Different Approach to Capital Allocation
In an October 26, 2026, filing, Strategy reported that it had repurchased approximately 2.07 million shares of its STRC preferred stock for $204.9 million during the previous week. It made no Bitcoin purchases during that period, leaving its holdings unchanged at 848,517 BTC.
The company also reported $4.83 billion in its reserve for preferred-stock dividends and debt interest, alongside $242.4 million in cash for broader treasury and capital-management purposes.
However, Strategy’s buybacks are not directly equivalent to Bitmine’s. Strategy repurchased preferred shares, which have different financial rights and dividend terms from ordinary shares.
Bitmine’s reported repurchases involved its common stock. The distinction matters because buying back preferred shares can affect a company’s financing costs and capital structure differently from reducing its common share count.
What Crypto Treasury Investors Should Watch Beyond Asset Holdings
The comparison highlights four choices facing crypto treasury companies:
-
Accumulate more crypto: Increase Bitcoin or Ethereum holdings, while accepting greater exposure to price movements.
-
Repurchase shares: Return capital to shareholders indirectly when management believes the market price offers value.
-
Preserve cash: Keep enough liquidity to meet debt payments, dividends, operating costs, and future needs.
-
Generate treasury income: Use activities such as Ethereum staking to earn rewards, while accounting for their risks.
Bitmine’s October 26 update reported both a 10,452 ETH purchase and $45.9 million in common-stock buybacks during the same week. This suggests that its strategy is not simply to accumulate as much ETH as possible, but to decide how each dollar can best support shareholder value.
For investors, the key question is whether management allocates capital effectively. Crypto holdings matter, but so do financing costs, cash reserves, and the relationship between a company’s stock-market value and its underlying assets. Neither buying more crypto nor repurchasing shares guarantees better returns.
Bitmine’s strategy depends on Ethereum’s market performance, the effectiveness of its share buybacks, and its ability to generate income from staking. Each approach carries risks that could affect the company’s financial position and the value investors receive from holding BMNR shares.
How an ETH Price Decline Could Affect Bitmine’s Treasury
Ethereum’s price directly affects the dollar value of Bitmine’s treasury. If ETH falls significantly, the company’s asset value could decline even if it continues accumulating tokens. Its substantial exposure to Ethereum means a prolonged downturn could weaken investor confidence and put pressure on BMNR shares.
Why Bitmine’s Share Buybacks May Not Increase BMNR’s Stock Price
Share buybacks can improve the value represented by each remaining share when a company repurchases stock below its underlying value. However, they do not guarantee that the market price will rise. Investors may continue to value BMNR at a discount because of uncertainty about ETH prices, financing costs, or the sustainability of Bitmine’s strategy.
It is also important to distinguish between increasing the amount of ETH attributable to each share and generating a positive stock-market return. The first does not automatically lead to the second.
Can Staking Risks and Liquidity Needs Limit Bitmine’s Strategy?
Staking allows Bitmine to earn rewards on ETH it holds, but those rewards can change with network conditions and staking yields. Validator failures or certain operational errors can also lead to penalties, while withdrawals may take time depending on the staking arrangement and network conditions.
Bitmine must therefore balance staking income against liquidity needs and the possibility of a market downturn. The central question for investors is whether the company can continue accumulating ETH, make disciplined buybacks, and meet its financial obligations without taking on excessive risk.
Bitmine’s decision to buy back shares while continuing to accumulate Ethereum reflects a broader capital-allocation strategy. By balancing ETH purchases, share repurchases, and staking income, the company aims to grow its treasury while creating value for shareholders.
However, falling ETH prices, uncertain staking returns, and ineffective buybacks could limit those benefits. Ultimately, whether Bitmine’s strategy succeeds will depend not only on how much ETH it holds, but also on how effectively management allocates capital and manages risk over time.
Why Is Bitmine Buying Back Shares Instead of More Ethereum?
Bitmine is repurchasing shares when management believes BMNR stock is undervalued, while continuing to accumulate Ethereum. The strategy aims to improve shareholder value through disciplined capital allocation.
How Much Ethereum Does Bitmine Own?
As of October 25, 2026, Bitmine reported holding approximately 6.05 million ETH, representing about 4.95% of the total Ethereum supply cited in its announcement.
How Do Bitmine’s Share Buybacks Benefit BMNR Shareholders?
Buybacks can increase each remaining shareholder’s proportional ownership and potentially improve net asset value per share when repurchases occur below underlying value. However, they do not guarantee stock price gains.
What Is Bitmine’s 5% Ethereum Supply Target?
Bitmine aims to hold 5% of Ethereum’s total supply, a goal it calls the “Alchemy of 5%.” Reaching it would give the company a substantial ETH treasury, but would not guarantee investor returns.
