Bitmine Immersion Technologies, an NYSE-listed company run by Tom Lee, disclosed that it continued building its Ether treasury last week—adding 32,447 ETH as the token rebounded sharply after an extended decline. The purchase lifts Bitmine’s total Ether holdings to 5,847,611 ETH, according to the company’s Monday update.
The latest buying pace keeps Bitmine on a nearly continuous accumulation schedule tied to its stated Ethereum treasury strategy, launched on June 30, 2025. With the firm now staking most of its position, the disclosure also offers a snapshot of how large spot treasuries can swing in value when the market turns.
Key takeaways
- Bitmine bought 32,447 ETH last week, bringing total holdings to 5,847,611 ETH—about 4.8% of Ethereum’s circulating supply.
- The company says it has acquired ETH every week since June 30, 2025, extending its buying streak to roughly 14 months.
- Bitmine is about 97% of the way toward its goal of owning 5% of the ETH supply.
- Of its Ether holdings, 5.07 million ETH is staked—around 87% of what Bitmine owns.
- Earlier losses tied to ETH’s drawdown have narrowed, with DropsTab data showing unrealized paper losses falling below $5 billion from more than $8.4 billion about a week earlier.
Bitmine keeps stacking Ether as the rebound gathers pace
Bitmine’s Monday disclosure confirms that last week’s ETH purchase was not isolated—it continued a weekly accumulation pattern that began when the company launched its Ethereum treasury strategy on June 30, 2025. With Ether prices stabilizing and then rallying, the firm’s latest tranche arrives at a time when its portfolio valuation is improving relative to the prior downturn.
According to the report, Bitmine now holds 5,847,611 ETH, which equates to roughly 4.8% of Ethereum’s circulating supply. The company also reiterated that it is nearing its target: it is reported to be 97% toward owning 5% of the ETH supply.
Bitmine’s NYSE-traded shares opened the week up about 8.7%, following a stretch that has already put gains at nearly 28% over the past six months. While share moves are not solely determined by crypto prices, the timing underscores how investors can respond to disclosures about on-chain treasury activity during volatile market phases.
How staking and treasury size shape the risk profile
The company’s Ether position is not only large—it is also largely staked. Bitmine reported staking 5.07 million ETH, representing about 87% of its holdings. Staking doesn’t eliminate price risk, but it changes how a treasury can pursue yield while remaining exposed to Ethereum’s market value.
Bitmine also provided a broader balance sheet snapshot, reporting combined crypto, cash, securities, and other investments of $14.9 billion. For readers tracking treasury strategies, this matters because valuation gaps in crypto holdings can be cushioned or amplified by how much capital the company holds outside of digital assets and by whether those assets are liquid versus locked or staked.
In practice, a treasury that keeps buying through downturns can end up with substantial unrealized losses during bearish periods. When markets rebound—especially sharply—those losses can narrow quickly, improving net asset value on paper even if the underlying strategy and risk exposures have not changed.
Why Ether’s rally mattered to Bitmine’s paper losses
Bitmine’s accumulation during the downturn left it facing steep unrealized losses when ETH prices fell. The recent recovery, however, has materially reduced that gap. DropsTab data cited in the disclosure indicates Bitmine has invested more than $19.5 billion in its Ether treasury, while unrealized losses have come down to below $5 billion from more than $8.4 billion roughly a week earlier.
The reported swing highlights a key operational challenge for crypto treasuries: digital asset valuations can change rapidly, sometimes in both directions, forcing investors to think in terms of marked-to-market exposure rather than only realized gains or losses. For companies building long-term crypto reserves, that volatility becomes part of the investment story—even when the buying cadence remains steady.
Bitmine’s latest purchase also aligns with a broader market move. Ether outperformed Bitcoin starting last Wednesday, when the US Treasury announced plans to double its monthly purchases of certain longer-dated US Treasurys to $4 billion from $2 billion beginning next month, as reported by Cointelegraph’s markets coverage.
CoinMarketCap data referenced in the disclosure shows Ether gained more than 32% since that announcement, breaking above $2,500 for the first time since January. For a treasury operator like Bitmine, that type of price action can quickly shift the narrative from “drawdown management” to “valuation recovery,” even if the company continues to execute the same acquisition strategy.
Treasury accumulation in context: what investors should watch next
Bitmine is approaching its 5% ETH supply target while maintaining a heavy staking allocation. That combination—sustained spot accumulation plus high staking participation—can influence how markets interpret the company’s longer-term commitment to Ethereum.
Still, several questions remain important for investors monitoring this strategy. How consistently Bitmine will be able to purchase ETH week after week if market volatility returns is one. Another is how much of its Ether is held in a form that can be deployed versus locked in staking. Finally, broader macro developments—such as how US Treasury policy and liquidity conditions continue to affect risk assets—could determine whether the current ETH rebound sustains or fades.
For now, the immediate watch item is whether Bitmine’s ongoing weekly purchases continue at the same pace as its unrealized loss position improves, and whether Ethereum’s momentum holds beyond the post-announcement rally.
