Bitmine adds 53,501 ETH, lifting holdings to ~4.9% of Ethereum supply
The 65-week accumulation streak leaves the firm near its stated 5% target despite about $5.1B in unrealized losses.
Bitmine Immersion Technologies added 53,501 ETH last week, extending its Ether buying streak to 65 consecutive weeks and pushing its treasury above 5.9 million ETH. The position now represents about 4.9% of Ethereum’s circulating supply, putting a single corporate holder within reach of a self-declared 5% ownership target even as it remains underwater on paper.
Bitmine Adds 53,501 ETH, Taking Its Treasury to ~4.9% of Supply
Bitmine Immersion Technologies extended its Ether accumulation streak to 65 consecutive weeks by adding 53,501 ETH in the latest week, continuing a strategy it kept running through the prior downturn and into the current recovery.
After the purchase, Bitmine’s holdings stood at more than 5.9 million ETH, valued at roughly $14.8 billion using an ETH price of $2,511 as of Sunday. On that math, the company’s treasury is now directly exposed to spot moves around the $2.5K area, because even small percentage swings translate into large balance-sheet mark-to-market changes at this size.
The bigger number for market structure is concentration. Bitmine’s ETH stash equals about 4.9% of Ethereum’s 120.7 million circulating supply, meaning a single corporate treasury is sitting on a whale-scale share of the float that traders typically assume is distributed across exchanges, long-term holders, and staking infrastructure.
That concentration is arriving with a visible cost. Bitmine was sitting on roughly $5.1 billion in unrealized losses on its Ether holdings, per DropsTab data, a reminder that the firm accumulated through the drawdown that began in the fourth quarter of the prior year and pushed Ether and the broader crypto market sharply lower. The article-level friction is that Bitmine’s average purchase price and the methodology behind the unrealized-loss estimate are not disclosed here, so the loss figure is best treated as a directional snapshot rather than a precise liquidation threshold.
Bitmine chairman Tom Lee tied the strategy to relative performance since late June, saying Ether, Bitcoin, and Solana have been the three best-performing major assets since June 30, with ETH leading the gains. “We believe this sets the stage for institutions to add to their crypto holdings given the substantial outperformance of crypto versus other macro assets in 3Q so far,” Lee said.
BMNR, the company’s NYSE-traded equity, has been trading like a read-through on that treasury narrative. Shares were up 1.3% on Monday morning to $24.09 and were poised to end the month up almost 40%, according to Yahoo Finance data.
The 5% Target as a Tradable Concentration Signal: What to Monitor Next
The near-term tell is whether Bitmine keeps printing weekly buys that move the treasury from ~4.9% to its stated 5% ownership target. At this scale, the market impact is less about any single week’s purchase and more about whether the streak continues as a policy, because that’s what turns the company into a persistent source of incremental demand.
ETH spot behavior around the $2,511 reference price matters because it is the level used to frame the treasury’s $14.8 billion valuation, and it is the cleanest public anchor for how quickly the balance sheet can swing. With a position measured in millions of ETH, the company’s sensitivity to price is not theoretical, and it can become a headline driver if the strategy ever shifts from accumulation to risk management.
The other missing piece is cost basis. Any new disclosure that clarifies Bitmine’s average purchase price, or updates the reported ~$5.1B unrealized loss figure with clearer methodology and timestamps, would change how traders interpret the odds of selling, hedging, or treasury rebalancing under stress.
Equity traders also have a straightforward feedback loop to watch after an almost-40% month in BMNR. If the stock continues to be rewarded alongside ETH strength, it reinforces the “crypto-treasury” playbook as a viable funding narrative, but if BMNR starts to fade while the ETH position keeps growing, the market is effectively repricing the balance-sheet risk.
My Read: A Whale-Scale Corporate Treasury That’s Still Underwater Can Cut Both Ways
The filing-equivalent detail here is the percentage, not the streak. Once a single corporate treasury is sitting on ~4.9% of circulating ETH, the threshold that matters is whether the firm treats 5% as a finish line or a waypoint, because that choice determines whether traders should model Bitmine as steady bid support or as a future source of supply and headlines.
The reported ~$5.1B unrealized loss is the other side of the setup, since it implies the company accumulated through the drawdown and remains underwater even after the recovery, with cost-basis uncertainty making it hard to map where hedging or de-risking might start. If Bitmine discloses a clearer cost basis and keeps buying through 5% without changing mechanics, the concentration becomes a structural flow factor rather than a narrative catalyst.
