BitMine Launches MAVAN, Claims Top Spot as Largest Ethereum Staker

BitMine Immersion Technologies (BMNR) has launched an institutional-grade Ethereum (ETH) staking platform dubbed 'MAVAN', a move the company says positions it as the world’s largest single Ethereum staker and signals intensifying competition for 'institutional demand' in on-chain yield products.

The U.S.-based blockchain infrastructure firm announced the official rollout of MAVAN—short for 'Made in America Validator Network'—on March 25. As of 5:00 p.m. ET on March 24, BMNR held 3,142,643 ETH, which the company valued at roughly $6.8 billion using a Coinbase-referenced Ethereum price of $2,148. Based on that balance, BMNR said it has become the largest single entity staking Ethereum globally.

BMNR’s accumulation accelerated into the launch. Over the prior week, the firm staked an additional 101,776 ETH, adding more than $219 million in ETH exposure at the same reference price. The company said that if it stakes its full ETH inventory through MAVAN, it expects annual revenue of about $300 million—an estimate that hinges on network-level staking yields, validator performance, fees, and potential changes in Ethereum’s broader staking economics.

The announcement comes as staking shifts from a retail-dominated activity toward a more professionally managed corner of the market. For institutions, staking has increasingly been framed as a way to seek 'native yield' on long-term crypto holdings, but the trade-offs—custody design, slashing risk, operational uptime, and regulatory posture—have pushed demand toward platforms that can offer stronger controls and compliance assurances. BMNR is leaning into that narrative with MAVAN’s U.S.-based validator positioning, emphasizing security and a compliance-forward operating model targeted at large allocators.

Investors backing BMNR include Cathie Wood’s ARK Investment Management and Pantera Capital, providing the company with recognizable institutional endorsements as it scales its staking business. Still, BMNR’s equity remains volatile, underscoring the market’s tendency to treat crypto-linked stocks as high-beta proxies for underlying token prices and sentiment.

BMNR’s market capitalization is about $9.5 billion, with shares recently trading around $21.24, far below the stock’s 52-week high of $161. The sharp drawdown highlights the sensitivity of publicly listed crypto infrastructure firms to shifting expectations around token prices, yields, and the durability of revenue models tied to on-chain activity.

Beyond Ethereum, BMNR said it intends to expand MAVAN into other Proof-of-Stake networks, aiming to capture a broader slice of the 'liquidity inflow' moving into staking across multiple ecosystems. The company also said it is pursuing post-quantum technology initiatives, reflecting a growing industry focus on long-horizon security assumptions as quantum computing research advances.

With MAVAN now live, market attention is likely to focus on whether BMNR can sustain validator performance at its new scale, manage concentration and operational risks, and translate headline staking volume into more stable earnings—factors that could ultimately shape how investors price the company’s role in the evolving institutional staking landscape.
