The Ethereum Foundation has completed its second direct OTC sale to BitMine Immersion Technologies in six weeks, moving 10,000 ETH at an average of $2,387 for $23.87 million, as the company chaired by Fundstrat's Tom Lee approaches a 5% ownership stake in Ethereum's entire circulating supply and a new market structure takes shape around it.
The transaction itself is unremarkable on its face. The Ethereum Foundation sells ETH periodically to fund operations. It has done so since the network launched. Protocol research, ecosystem development, community grants: these things cost money, and the foundation's primary treasury asset is ETH, so ETH gets sold. What makes the current situation structurally interesting is not the selling. It is who is buying, how consistently they are buying, and what that relationship is beginning to look like from the outside. BitMine has now purchased directly from the Ethereum Foundation three times in 2026: once in January, once in March for 5,000 ETH at $2,042 per token, and now again in April for 10,000 ETH at $2,387. Over a twelve-week window, the foundation has transferred 20,000 ETH to a single counterparty via private OTC deals, extracting approximately $52 million from a company that then stakes most of what it holds and treats it as permanent treasury capital.
BitMine's current position is worth pausing on. The company, listed on Nasdaq as BMNR, holds approximately 4.976 million ETH as of the April deal close. That is roughly 4.12% of Ethereum's total circulating supply, with a current market value above $11.5 billion. Of those holdings, 72.1%, or about 3.588 million ETH, are actively staked, meaning they are contributing to network security and generating yield simultaneously. The company is targeting 5% of circulating supply as its strategic benchmark. At the current accumulation rate, which included a single-week purchase of 101,627 ETH in BitMine's largest weekly buy of 2026, that target is close. A single company holding 5% of a major proof-of-stake network's supply, with most of it locked in staking, is not a straightforward situation from a governance or market structure perspective. It is new territory.
The Bitcoin treasury company comparison is instructive but limited. Strategy, the company formerly known as MicroStrategy, pioneered the model of treating Bitcoin as a primary corporate treasury asset, using debt and equity issuance to accumulate at scale and positioning the holding as a strategic reserve rather than a speculative trade. That model spawned imitators across multiple assets. BitMine is executing the same playbook on Ethereum with one significant difference: Bitcoin has no protocol foundation with a treasury to sell into. The Ethereum Foundation does, and it has chosen BitMine as a preferred direct buyer. That is a qualitatively different relationship than a company buying on the open market. It means the primary steward of the protocol and its largest single institutional holder have a recurring bilateral transaction arrangement. The implications for governance, for optics, and for the question of who effectively controls a meaningful share of network stake deserve more scrutiny than they have received.
The foundation's explanation for these sales is consistent and credible on its own terms. It maintains an operating expense buffer denominated in fiat, because protocol researchers and grant recipients cannot pay rent in ETH. When the fiat buffer falls below its target range, the foundation converts ETH to maintain it. Using OTC transactions rather than exchange sales minimises spot market impact and avoids signalling that creates front-running opportunities. Selecting a buyer with a long-term holding strategy, one that will stake rather than flip, is arguably the most responsible available approach to managing supply impact. The foundation has also recently begun executing transactions through a disclosed multisig wallet on-chain, improving transparency around treasury activity after years of community criticism about opaque sales. On every operational metric, the current approach is an improvement over historical practice.
The community reaction is split in predictable ways. Critics argue the foundation should stake its holdings to generate yield rather than selling, pointing out that the ETH being sold could be earning approximately 3% to 4% annually if staked, producing operating revenue without reducing the treasury's ETH balance. The counter-argument is that staking introduces slashing risk, concentrates validator weight at the foundation, and creates a conflict of interest for an organisation that is also responsible for Ethereum protocol governance. The foundation has consistently declined to stake at scale for these reasons. That position is coherent. It also means the foundation will continue to be a regular seller into a market where institutional demand is growing, and where a single counterparty is increasingly the buyer of first resort.
For the broader Ethereum ecosystem, the emergence of BitMine as an entity approaching 5% of supply custody raises questions that have no clear precedent. Proof-of-stake networks derive security from the distribution of staked capital. Concentration of that capital in a publicly traded company, subject to shareholder pressure, regulatory scrutiny, and market conditions, introduces a dependency that differs categorically from the distributed validator set that Ethereum's security model was designed around. BitMine staking 72% of its 4.97 million ETH means it controls a significant portion of network validation weight. If that position were ever forcibly liquidated, under regulatory pressure, financial distress, or shareholder action, the effect on both network security and ETH price would be material. That scenario is not imminent, and BitMine's stated strategy is indefinite accumulation. But the scenario is no longer theoretical, and the Ethereum Foundation's repeated decision to sell directly to BitMine is quietly accelerating the concentration it creates.
