BitMine’s Ether Treasury Tops $17 Billion as Weekly ETH Buying Streak Nears 5% of Supply

A $17 Billion Bet on Ethereum Takes Center Stage

BitMine Immersion Technologies (NYSE: BMNR) has made a habit of producing headlines, but Monday’s disclosure is arguably its most striking yet. The Norwalk, Connecticut-based company, which has positioned itself as a pure-play Ethereum treasury firm under the chairmanship of Tom Lee, revealed that it acquired another 27,562 ETH over the previous seven days. That may sound like a modest weekly addition for a company of its size, but it was enough to push BitMine’s total hoard to 5,983,940 ether tokens — a position worth roughly $16 billion at prevailing market prices and representing nearly 4.9 percent of all ether in circulation. Combined with its cash, marketable securities, a small bitcoin stash and two strategic equity stakes, the company’s total reserves now clear the $17 billion mark. If there was any lingering doubt about whether a public company can become a dominant force in digital assets, BitMine has effectively erased it.

The disclosure confirms what industry watchers have suspected for months: BitMine is not merely dabbling in cryptocurrency. It is building an institutional-grade ether reserve at a pace that has no real equivalent among public companies. According to the release, the company’s holdings of Ethereum now make it the largest public holder of ether on the planet. That is a remarkable title for a firm that many investors still associate more with bitcoin mining than with the world’s second-largest cryptocurrency. But BitMine’s strategy has evolved, and the Monday update makes clear that evolution is intentional. The company isn’t just accumulating a digital asset and waiting for prices to rise. It is actively earning yield on the vast majority of its ETH holdings, while using its balance sheet to fund additional purchases. The result is a treasury operation that looks less like a passive bet and more like a fully functioning, income-generating investment vehicle.

Four Point Nine Percent and Closing In on the “Alchemy of 5%”

To understand the scale of BitMine’s position, it helps to put the numbers in context. As of September 20, the company valued its ether at $2,688 per token, placing the ETH portion of the portfolio at approximately $16.08 billion. That alone would be enough to make BitMine a heavyweight in the institutional crypto world. But the balance sheet doesn’t stop there. BitMine also holds 212 bitcoin, $714 million in cash and marketable securities, a $180 million stake in logistics and industrial firm Beast Industries, and a $105 million stake in Eightco Holdings, which trades on the Nasdaq under the ticker ORBS. Taken together, those positions put the company’s combined cryptocurrency, cash and equity reserves at roughly $17.1 billion.

The more intriguing number, though, is the share of the total ether supply that BitMine now controls. With 5,983,940 ETH in hand, the company owns approximately 4.9 percent of the entire 122.1 million token supply. That is almost one in every twenty ether tokens in existence, a level of concentration that would be remarkable in any liquid asset class. BitMine has been transparent about its ambitions here, describing the 5 percent threshold as a key milestone — what its materials call the “alchemy of 5%.” The latest purchase brings the company to the edge of that psychological barrier. Analysts who follow the space will likely be watching closely in the coming weeks to see whether BitMine crosses the line and, more importantly, what it does after that. Reaching 5 percent would not just be a symbolic victory; it would cement BitMine’s role as one of the single most influential entities in the Ethereum ecosystem.

A Weekly Buying Habit Backed by Mining Cash and Capital Raises

The latest acquisition is not a one-off maneuver. Tom Lee, the company chairman, was characteristically direct in the release: “Over the past week, we acquired 27,562 ETH. BitMine has bought ETH each and every week since the inception of its ETH Treasury Strategy on June 30, 2025.” That weekly cadence has become a defining feature of BitMine’s corporate identity. While other companies may buy digital assets opportunistically, BitMine has turned ether accumulation into a recurring, almost metronomic ritual. Every week, regardless of market conditions, the company adds to its position. The strategy has drawn comparisons to the playbook popularized by MicroStrategy in the bitcoin space, but with an important twist: BitMine is doing it with Ethereum, and it is doing it on a far larger scale relative to the asset’s total supply.

Where does the money come from? BitMine funds the program through its bitcoin mining operations and the proceeds of capital raises. That gives the company a steady stream of cash that it can convert into ether without needing to sell existing holdings. It also means that the weekly purchases are supported by real business operations, not just market timing or speculative enthusiasm. The company’s most recent update follows a disclosure from the prior week in which BitMine’s holdings crossed 5.96 million ETH. In the space of a few days, that figure has climbed to just under 5.99 million. At this pace, the company will likely surpass the 6 million ETH mark in the near future — and, with it, the fabled 5 percent threshold. For investors, the message is clear: BitMine’s appetite for ether has not diminished, and there is little to suggest it will slow down anytime soon.

Staking 85% of the Treasury: A $357 Million Revenue Stream

What sets BitMine apart from other crypto-heavy balance sheets is what it does with the assets it holds. The company is not simply sitting on its ether and hoping for appreciation. Of the 5,983,940 ETH in its treasury, 5,067,309 tokens — worth approximately $13.6 billion, or about 85 percent of the total position — are currently staked. Staking involves locking up ether to help secure the Ethereum network, and in return, participants earn rewards. BitMine says its staked position is currently generating a seven-day annualized yield of 2.62 percent. That may not sound explosive, but on a $13.6 billion position, the numbers add up quickly. Tom Lee noted that BitMine has now “staked more ETH than other entities in the world,” a claim that positions the company not only as the largest public holder of ether but also as the largest single staker anywhere in the ecosystem.

The revenue potential is substantial. According to the company, annualized staking revenue is currently projected at roughly $357 million. That figure is expected to rise to approximately $421 million once the full stack is deployed through the company’s MAVAN staking platform. In other words, BitMine is turning its Ethereum treasury into an income-producing engine, generating hundreds of millions of dollars in annual rewards while maintaining exposure to potential price appreciation. This is a meaningful shift from the old model of corporate crypto treasuries, where assets simply sat on the balance sheet. By staking its ether, BitMine earns additional tokens over time, which compounds its holdings and further strengthens its position as the dominant public owner of Ethereum. It also reinforces the argument that ether is not just a speculative asset but a productive one, capable of generating yield in the same way that dividends or interest payments flow from traditional investments.

Beyond Ether: “Moonshots” and a Diversified Treasury

While Ethereum is clearly the centerpiece of BitMine’s balance sheet, the company’s treasury is more diversified than it might appear at first glance. Alongside its enormous ETH holdings, BitMine owns a relatively modest 212 bitcoin, a position that seems almost quaint by comparison but still adds to the portfolio’s overall diversity. More importantly, the company holds $714 million in cash and marketable securities, giving it ample liquidity to fund future purchases or weather periods of market volatility. On top of that, BitMine has taken strategic equity positions in two companies it describes as “moonshots”: a $180 million stake in Beast Industries and a $105 million stake in Eightco Holdings. These are not typical treasury assets. They are speculative bets with the potential for outsized returns — the kind of investments that could deliver a windfall if they succeed or be written down if they don’t.

This mix of stability and speculation suggests that BitMine is thinking carefully about risk, even as it pushes deeper into crypto. The cash and marketable securities provide a cushion. The bitcoin position adds a familiar digital asset that behaves differently from ether. The equity stakes, meanwhile, offer an asymmetric opportunity: they could fail entirely, but they could also prove to be far more valuable than their current carrying values. By labeling them “moonshots,” the company is signaling to shareholders that these are high-risk, high-reward positions — exactly the kind of bets that could enhance returns if the stars align. What emerges is a treasury strategy that is aggressive but not reckless, concentrated but not single-dimensional. BitMine is betting heavily on Ethereum, but it is also building a broader portfolio that can support that bet during difficult periods.

What BitMine’s Strategy Signals for Institutional Crypto Markets

The broader implications of BitMine’s accumulation campaign extend well beyond one company’s balance sheet. By holding nearly 5 percent of the entire ether supply, BitMine has become a structural force in the Ethereum market. Its weekly purchases create a steady, predictable source of demand, while its staked holdings reduce the amount of liquid ether available to other investors. That combination can tighten the market and potentially support prices over time, especially as institutional interest in Ethereum continues to grow. The company’s willingness to stake 85 percent of its holdings also signals confidence in Ethereum’s long-term viability, since staked tokens are locked up and cannot be sold quickly without an exit process. In effect, BitMine has committed itself to Ethereum in a way that few other companies have committed to any asset.

Looking ahead, the “alchemy of 5%” may be just the beginning. If BitMine maintains its weekly buying streak, it will almost certainly push past that threshold in the near future. Whether that leads to even more aggressive accumulation remains unclear, but the company’s history suggests it is not easily satisfied. At the same time, BitMine’s strategy could inspire other public companies to follow suit, particularly those looking for ways to generate yield from digital assets while maintaining exposure to appreciation. In that sense, BitMine is not just a participant in the crypto market; it is a template for how a modern corporate treasury can operate in a world where digital assets are increasingly mainstream. With $17 billion in reserves, a weekly buying habit and a staking operation that generates hundreds of millions of dollars in annual income, BitMine has shown that the line between cryptocurrency investing and traditional corporate finance no longer exists. For Tom Lee and his team, that is not a problem — it is the point.
