BitMine buys 126,971 ETH amid selloff

TLDR

BitMine Immersion Technologies has just made its largest weekly Ethereum purchase, buying 126,971 ETH while the crypto market was selling off.

1. BitMine bought 126,971 ETH, around 207214 million dollars, lifting its holdings to about 5.54 million ETH, roughly 4.59 percent of Ethereums circulating supply.
2. The firm is treating the selloff as a buying opportunity, with about 85 percent of its ETH staked and generating an estimated 230 million dollars in annualized staking revenue.
3. This level of accumulation concentrates ETH in a single corporate treasury, so the key things to watch are BitMines path to 5 percent supply, its funding model, and any impact on Ethereums risk profile.

Deep Dive

1. What BitMine Just Did

BitMine Immersion Technologies (BMNR) disclosed that it acquired 126,971 ETH last week, spending roughly 207214 million dollars at an average price near 1,630 dollars per token as ETH hit June lows amid a broader selloff. This was described as its largest weekly ETH purchase of 2026 in multiple reports and an SEC 8-K filing.

After this buy, BitMine now holds about 5,543,872 ETH, equal to roughly 4.59 percent of Ethereums circulating supply of 120.7 million, with its ETH treasury valued around 9 to 9.6 billion dollars at the reported prices. An official holdings update noted that this puts the company about 92 percent of the way to its stated goal of owning 5 percent of all ETH in circulation, its so-called Alchemy of 5 percent target.

2. Why This Matters For Ethereum

BitMine is now the largest Ethereum treasury company, reportedly controlling about 73 percent of all ETH held by public companies, which makes its balance sheet a meaningful part of Ethereums ownership landscape.

Around 4.72 million ETH, roughly 85 percent of its holdings, are staked via its MAVAN institutional staking platform, with recent disclosures projecting about 230 million dollars in annualized staking revenue at a 2.99 percent yield, rising toward 270 million dollars if fully staked. This reduces freely tradable supply but also concentrates validator power and staking economics in one corporate actor.

Management framed the recent drawdown, partly triggered by an AI-discovered vulnerability in Zcash that spilled over into altcoins, as a superficial selloff and argued that improving fundamentals make Ethereum undervalued at these levels.

3. Risks And What To Watch Next

BitMine is funding much of this accumulation through equity and preferred stock offerings, including a 9.5 percent dividend Series A preferred share deal, rather than purely from operating cash flows. That model works best if ETH stabilizes or recovers, but it amplifies pressure if prices fall further while fixed dividends remain.

The firm is already sitting on large unrealized losses on its ETH stack due to the drawdown from prior peaks, even as it continues to buy more. If it ever slowed purchases sharply, sold into weakness, or faced funding stress, that could shift market sentiment from smart money buying the dip to concern about forced selling.

For the Ethereum ecosystem, the key structural questions are how much validator and governance influence BitMine ends up with as it pushes toward 5 percent of supply, and whether other treasuries copy this strategy or back away from concentrated crypto exposure.

Conclusion

BitMines 126,971 ETH buy is a textbook corporate buy the dip move, turning a sharp market selloff into its largest weekly accumulation and pushing it close to owning 5 percent of all ETH. That reinforces a narrative of strong institutional conviction in Ethereum, while simultaneously increasing concentration and balance sheet risk around a single, equity-financed treasury. How BitMine manages its funding, staking footprint, and future buying during volatility will be an important signal for both ETHs structural supply dynamics and broader market sentiment.
