BitMine Immersion Technologies (BMNR), the public company chaired by Fundstrat’s Tom Lee, has been aggressively accumulating Ethereum as part of its Alchemy of 5% strategy—aiming to hold 5% of the total ETH supply roughly 6.035 million ETH based on ~120.7 million circulating supply.
Recent reports confirm ongoing large weekly purchases. For example: As of late March 2026, BitMine added 71,179 ETH in one week, bringing its holdings to 4,732,082 ETH — approximately 3.92% of the total supply. Earlier in March, it added 65,341 ETH, reaching ~4.66 million ETH.
BitMine has steadily ramped up its pace from earlier averages of 45–50k ETH/week, even during periods of price pressure or mini crypto winter conditions. Recently reported at 4.73+ million ETH, making it one of the largest known corporate ETH treasuries. A significant portion is staked, generating substantial yield—estimates have ranged from $176M to $272M annualized depending on rates and scale.
They’re developing their own MAVAN (Made in America Validator Network) staking solution aimed at institutional use. Alongside ETH, they hold some BTC (197), cash ($961M in the latest update), and smaller moonshot investments. Total crypto + cash + other holdings recently hit ~$10.7 billion.
Purchases have continued despite unrealized losses at times due to higher average entry prices in prior periods and market volatility, including geopolitical factors mentioned in their releases. This corporate accumulation adds sustained buying pressure and locks up a notable chunk of ETH supply via staking, which can support network security and reduce liquid supply.
It’s part of a broader trend of institutions treating ETH as a treasury asset with yield potential post-Merge. BitMine’s progress toward 5% has been tracked publicly. Note that exact percentages can shift slightly with total circulating supply changes or precise timing of filings.
MAVAN (Made in America Validator Network) is BitMine Immersion Technologies’ (BMNR) proprietary, institutional-grade Ethereum staking platform. The company officially launched, after developing it internally to manage and monetize its large ETH treasury.
MAVAN was originally built to support BitMine’s own massive Ethereum holdings part of its Alchemy of 5% strategy aiming for ~5% of total ETH supply. It has now been opened to external clients, positioning it as a premier staking destination for: Institutional investors, custodians, exchanges and ecosystem partners.
The platform emphasizes security, performance, and resilience while addressing institutional needs such as regulatory compliance, geographic control, and operational reliability. Key architectural features include: U.S.-based infrastructure — This provides Made in America validation for clients who prefer or require domestic validators.
Flexible, globally distributed architecture — This allows support for worldwide clients while maintaining high uptime and performance. This hybrid model aims to reduce risks associated with validator concentration in the Ethereum network and offer a differentiated, compliant option in a space where many staking services rely on offshore or highly centralized providers.
BitMine had ~3.14 million ETH staked on MAVAN, valued at approximately $6.3–6.8 billion. This makes BitMine via MAVAN one of the largest—if not the single largest—Ethereum stakers globally. Recent activity included adding over 100,000 ETH in a single week to the platform. Projected annual staking rewards: Nearly $300 million, such as a ~2.8–2.83% 7-day annualized rate.
These figures assume BitMine stakes nearly all of its remaining unstaked ETH in the coming weeks. Staking rewards come from Ethereum’s proof-of-stake consensus mechanism, where validators earn ETH for securing the network. BitMine describes MAVAN as a foundational piece of its long-term infrastructure strategy.
Plans include: Expanding to additional proof-of-stake (PoS) networks beyond Ethereum. Developing related blockchain infrastructure services, such as on-chain vaults and post-quantum client development. Positioning MAVAN as one of the leading staking and on-chain platforms globally.
Recent moves, such as acquiring the Pier Two infrastructure site, further bolster its validator capacity to support institutional-scale operations. MAVAN turns BitMine’s ETH treasury from a pure holding into a yield-generating asset. Combined with its Bitcoin mining operations and smaller moonshot investments, it supports recurring revenue for the public company.
Chairman Tom Lee has highlighted MAVAN as a critical step in building institutional-grade crypto infrastructure. Staking involves risks such as slashing; penalties for validator downtime or misbehavior, though institutional platforms like MAVAN aim to minimize these through robust operations. Yields fluctuate with Ethereum network conditions.
As a relatively new launch, full operational details and third-party audits may evolve; MAVAN is BitMine’s in-house solution to securely stake massive amounts of ETH while creating a scalable, U.S.-anchored service for other large players—blending self-custody of its treasury with a B2B infrastructure play.
