BitMine Reveals $12.3 Billion Crypto Portfolio, Launches Ethereum Staking Platform MAVAN

BitMine Immersion Technologies ($BMNR) has disclosed a $12.3 billion portfolio of crypto, cash, and investments—dominated by a massive Ethereum (ETH) position—and unveiled a new institutional staking platform branded 'MAVAN', underscoring the firm’s push to turn treasury holdings into a recurring yield business.

In company materials and matching U.S. Securities and Exchange Commission filings, BitMine reported holdings that include roughly 5.39 million Ethereum (ETH) and about $444 million in cash. Of that ETH stack, approximately 4.71 million ETH is currently staked, representing around 4.47% of Ethereum’s total supply—an unusually concentrated position for a single corporate holder and one that places the company among the ecosystem’s most consequential validators by scale.

BitMine said it accumulated ETH at prices below $2,200. For valuation purposes, the company marked its ETH at $2,134, implying the purchases were timed to take advantage of market weakness and could translate into meaningful unrealized gains depending on spot price levels. The disclosure comes as investors continue to scrutinize how corporates are managing crypto treasuries amid shifting liquidity conditions and renewed debate around the durability of staking yields.

The company’s new platform, 'MAVAN (Made in America VAlidator Network)', is aimed at institutional-grade Ethereum staking for both BitMine and third-party clients. By positioning itself as a staking services provider rather than only a balance-sheet accumulator, BitMine is signaling a strategy to diversify revenue and build a more durable operating model tied to network participation.

BitMine said MAVAN has delivered an average 2.75% yield over the past seven days and projected annualized revenue of about $276 million based on current assumptions. Market participants typically caution that staking returns fluctuate with network conditions, validator participation, and on-chain fee dynamics, but the projection highlights BitMine’s intention to frame its ETH exposure as a yield-generating infrastructure play.

Management also reiterated a roadmap it refers to as 'Alchemy 5%', targeting ownership of 5% of Ethereum’s total supply by 2026. With BitMine currently disclosing 4.47%, that goal would require adding roughly 0.53 percentage points—about 610,000 additional ETH—suggesting further balance-sheet expansion could remain central to its long-term plan. If executed, the company would further entrench itself as a major stakeholder in Ethereum’s validator set, a position that can carry both influence and heightened responsibility given ongoing decentralization concerns.

On the equities side, BitMine continues to trade on the New York Stock Exchange following its April 9, 2026 transfer listing under the ticker $BMNR. The stock has recently seen elevated turnover, with the company citing an average daily trading value of roughly $572 million over the past five sessions—activity that may reflect increased institutional attention to crypto-linked public equities.

Shares were last indicated at $19.20, with an intraday range of $19.025 to $20.05. Over the past 52 weeks, the stock has traded between $3.92 and $161.00, underscoring the volatility investors often associate with crypto-adjacent business models and balance sheets heavily exposed to digital asset prices.

BitMine emphasized that the figures in its press release align with its SEC submissions, a point likely aimed at reinforcing 'transparency' as large treasury holders face growing demands for clear disclosures on custody, staking arrangements, and risk management. For institutional allocators, consistent reporting and a coherent business strategy are often viewed as prerequisites before engaging with crypto yield products or staking providers at scale.

Beyond the financial optics, BitMine’s 4.71 million ETH staked is also positioned as a contribution to network security, since staking helps validate transactions and maintain Ethereum’s consensus mechanism. By opening MAVAN to external institutions, BitMine is effectively expanding from a large-holder profile into a crypto infrastructure operator—an evolution that could broaden its footprint in the Ethereum ecosystem as competition intensifies among professional staking services.
