Bitmine Immersion Technologies has expanded its Ethereum treasury again, disclosing that it purchased 60,999 ETH over the past week. The latest acquisition lifted the company’s total holdings to 4,595,562 ETH, valued at roughly $10 billion at recent market prices and representing about 3.81% of Ethereum’s circulating supply. Including its crypto assets, cash, and strategic investments, Bitmine said its total portfolio stood at approximately $11.5 billion as of March 15.
Ethereum Treasury Strategy Scales Up
The latest purchase reinforces Bitmine’s emergence as one of the most significant institutional holders of ether. The company’s balance sheet now includes not only a massive ETH reserve but also 196 BTC, cash, and a group of venture-style strategic investments. In practical terms, Bitmine is building a public-market vehicle that offers investors concentrated exposure to Ethereum through a corporate treasury model.
That approach has drawn comparisons to the strategy that MicroStrategy used with bitcoin, except Bitmine is applying the same logic to ether. By accumulating a meaningful share of Ethereum’s available supply, the company is positioning itself as both a treasury holder and a major economic participant in the network.
Staking Is a Core Part of the Model
A large portion of Bitmine’s ETH is not sitting idle. The company said 3,040,515 ETH is currently staked, representing about $6.6 billion in assets helping secure the Ethereum network. Bitmine reported a 2.81% seven-day staking yield, slightly above the 2.79% Composite Ethereum Staking Rate (CESR).
This detail is important because it shows the firm is treating ether as a productive treasury asset rather than a passive balance-sheet reserve. In addition to potential price appreciation, Bitmine is seeking yield through staking, which may help support the economics of its aggressive accumulation strategy.
The company also said it is working with three staking providers as it prepares to launch its own validator infrastructure in 2026. That initiative, called MAVAN, or Made in America Validator Network, could give Bitmine more direct control over a large-scale Ethereum validation operation if the rollout proceeds as planned.
Management Remains Bullish on Ether
Bitmine Chairman Thomas “Tom” Lee voiced confidence in the company’s ETH-focused strategy. According to Lee, crypto assets have outperformed since the start of the Iran war, and ethereum has outperformed the S&P 500 by 2,450 basis points over a two-week period. While this reflects management’s market view rather than a guaranteed trend, it helps explain why the company continues to add to its Ethereum position at a rapid pace.
The pace itself has been notable. The company’s weekly purchases in early 2026 reportedly ranged from around 40,000 ETH to more than 60,000 ETH, following even larger buying in late 2025. Alongside the latest market purchases, Bitmine also acquired 5,000 ETH from the Ethereum Foundation, a transaction the report said helped fund the organization’s ongoing development work.
More Than a Crypto Treasury
Although Ethereum remains the centerpiece of Bitmine’s strategy, the company is also extending its capital into technology and media-related investments. It recently increased its stake in Eightco Holdings by $80 million. Eightco itself has made strategic allocations that include a $50 million equity investment in OpenAI and a $25 million stake in Beast Industries, the media venture founded by YouTube creator MrBeast.
Bitmine additionally disclosed a direct $200 million position in Beast Industries, alongside about $83 million in Eightco shares and roughly $1.2 billion in cash. These holdings suggest the company is trying to build a broader portfolio that spans digital assets, AI-linked exposure, and media-related growth investments, rather than functioning as a single-asset treasury alone.
A Growing Public-Market Presence
Bitmine’s profile in U.S. public markets is also rising. Citing Fundstrat data, the report said the company’s shares average around $1 billion in daily trading volume. That places the stock 105th among more than 5,700 U.S.-listed companies, just behind Nike and ahead of Starbucks in trading activity.
For market participants, that level of liquidity matters. It means Bitmine is increasingly becoming a publicly traded proxy for institutional Ethereum exposure, especially for investors who want access to the asset class through equities rather than direct token ownership.
Why the Market Is Watching Closely
Bitmine’s expanding treasury raises broader questions about concentration, institutional influence, and the role of corporate balance sheets in crypto networks. Controlling nearly 3.8% of Ethereum’s circulating supply is significant by any standard. Combined with more than 3 million ETH staked, the company is not only making a financial bet on ether but also becoming a major participant in Ethereum’s security and validation economy.
Whether that strategy ultimately proves visionary or risky will depend heavily on Ethereum’s long-term ability to remain central to decentralized finance and the wider tokenized economy. If ether continues to serve as a foundational asset for on-chain applications, Bitmine’s treasury could look highly strategic. If the market weakens or network economics shift, the same concentration could become a source of volatility.
For now, the message from Bitmine is clear: the company is accelerating its bet on Ethereum, pairing large-scale accumulation with staking income, validator ambitions, and a growing public-market profile. That combination makes Bitmine one of the most closely watched corporate players in the Ethereum ecosystem today.
