BitMine holds 4.8% of all Ether in circulation

BitMine Immersion Technologies has grown its Ethereum treasury to 5.815 million ETH, a holding equal to roughly 4.8% of the total circulating supply of the asset, according to the company’s own disclosures. The Nasdaq-listed company has become the largest corporate holder of ETH globally, running a treasury strategy modeled on the ETH-accumulation approach that several public companies have adopted over the past two years.

BitMine’s origins are worth noting for context: the company began as a bitcoin mining and immersion-cooling hardware business before pivoting toward an ether accumulation strategy, a transition that itself reflects how quickly corporate crypto strategy has shifted in recent years, from operating infrastructure that earns crypto through mining, to raising capital specifically to hold and stake it directly on the balance sheet. That pivot mirrors a broader trend among smaller public companies looking for a way to differentiate themselves in crowded, capital-intensive sectors like mining by repositioning around a large, disclosed treasury position instead.

How a position like this gets built

Reaching a treasury of nearly 6 million ETH is not a single purchase, it is the cumulative result of repeated capital raises and market purchases executed over an extended period. A company pursuing this strategy typically issues new shares or convertible debt to raise cash, then uses that cash to buy ETH on the open market, disclosing the updated holdings in periodic filings and press releases as the position grows. Because purchases of this scale can themselves affect market prices if not executed carefully, treasury companies generally spread buying across time rather than acquiring a position in one block, which is also why holdings tend to be reported as a running total that climbs steadily over successive disclosures rather than jumping all at once.

Scale of the holdings

BitMine disclosed that as of August 16, 2026, its total staked ETH stood at 5,067,309 tokens, valued at roughly $9.6 billion at a reference price of $1,893 per ETH. The company’s total crypto and cash holdings, including its ETH position and other reserves, reached $11.4 billion, according to a company announcement. The gap between the company’s total ETH holdings (5.815 million) and its staked ETH figure (just over 5.06 million) suggests a portion of the treasury remains unstaked, potentially held for liquidity or operational purposes rather than earning staking yield.

Staking, in Ethereum’s case, means locking ETH into the network’s proof-of-stake consensus mechanism, where validators put capital at risk in exchange for the right to propose and verify new blocks and earn a yield paid in newly issued ETH plus a share of transaction fees. A large holder staking most of its position both earns that yield on its balance sheet and, in aggregate with other stakers, contributes to the pool of capital securing the network against attempts to rewrite transaction history, since a validator’s staked ETH can be partially destroyed, a process called slashing, if it behaves dishonestly. Keeping a portion of a large treasury unstaked, as the gap in BitMine’s disclosed figures suggests, is a common practice among large holders because staked ETH is subject to withdrawal queues and cannot always be sold or moved instantly, so maintaining some liquid, unstaked reserve preserves flexibility to meet redemptions, cover expenses, or respond to market conditions without waiting on the unstaking process.

A treasury-company strategy taking hold

BitMine’s approach mirrors, on a larger scale, the corporate ETH-accumulation strategy that other public companies including SharpLink have pursued since 2025: raising capital through equity issuance and using proceeds to build a large, disclosed ETH position, then staking most or all of that ETH to generate yield that flows back to the company’s balance sheet. Because these positions are disclosed in public filings and updated periodically, they have become a closely watched category of institutional ETH demand distinct from ETF flows, since treasury companies typically hold their positions for extended periods rather than trading around short-term price moves.

The template for this kind of corporate treasury strategy was popularized in bitcoin markets before it was adapted to ether, with companies raising capital specifically to accumulate a crypto asset on the balance sheet rather than to fund a traditional operating business. The pitch to shareholders is that the company’s equity becomes a leveraged, liquid proxy for exposure to the underlying asset, one that can raise additional capital opportunistically to buy more of it, generate yield where the underlying asset supports staking, and trade with the liquidity of a listed stock rather than requiring investors to hold the asset directly. It also introduces a distinct risk that a spot ETF or direct holding does not carry: the company’s share price can trade at a premium or discount to the actual value of its underlying holdings, depending on investor sentiment toward the company’s strategy, management, and capital structure, meaning the equity does not always move one-to-one with the asset it holds even though that asset makes up the bulk of the company’s disclosed value.

Why it matters for the broader ETH market

A single company holding close to 5% of Ethereum’s circulating supply represents a meaningful concentration of ownership, even though the shares are dispersed across BitMine’s own public shareholder base. For the ETH market more broadly, large staked treasury positions like BitMine’s remove supply from active circulation and, when staked, contribute to network security, while also making the company’s own share price highly sensitive to ETH’s spot price. Canadian investors who want indirect ETH exposure through equities, rather than direct holdings or ETF units, have increasingly looked at treasury companies like BitMine as one avenue, though that exposure carries added company-specific and equity-market risk on top of ETH’s own price volatility.

That concentration also raises a longer-term structural question for Ethereum’s validator set. A large share of staked ETH controlled by one entity, even a well-disclosed public company acting through regulated channels, changes the distribution of influence over which blocks get proposed and validated relative to a network where staking is spread across many smaller, independent participants. Ethereum’s design does not give a single staker outsized voting power the way, for example, a majority shareholder controls a company, since validator selection is randomized and each validator’s influence is proportional to its own stake rather than compounding through governance rights. But a sufficiently large staked position held by one company is still a data point worth tracking for anyone assessing how decentralized Ethereum’s validator base actually is in practice, separate from how decentralized its protocol design intends it to be.
