Bitmine Immersion Technologies has launched MAVAN, an institutional-grade Ethereum staking platform that will run validator infrastructure for its own holdings and external clients. Staking involves locking up Ether to help validate network transactions in exchange for rewards.
MAVAN—Made in America Validator Network—was developed to support Bitmine’s Ethereum treasury and is now open to institutional clients and custodians. Bitmine, the largest public company holder of Ether, has already staked more than 3.1 million ETH and said it staked 101,776 ETH over the past week. The company plans to continue increasing the amount allocated to MAVAN and move to stake most of its remaining Ether holdings, estimating staking rewards could approach $300 million annually at current yields.
The platform will use US-based infrastructure alongside a globally distributed setup and is expected to expand to additional proof-of-stake networks and blockchain services. Bitmine is targeting institutions, custodians and exchanges and counts investors such as ARK Invest, Founders Fund, Kraken, Pantera Capital, Digital Currency Group and Galaxy Digital among its backers.
CoinGecko data show Bitmine currently holds 4,660,903 ETH, added 238,244 ETH over the past 30 days, and accounts for roughly 3.86% of the total Ether supply. The company says it aims to continue growing its holdings toward a stated goal of acquiring 5% of total ETH supply.
Institutional demand is reshaping Ethereum staking infrastructure as firms seek compliant, institution-grade setups and yield. Protocols and products are adapting: Lido’s modular upgrade allows institutions to customize validator configuration and withdrawal parameters; the Ethereum Foundation has begun staking part of its treasury, allocating around 70,000 ETH to validators for ecosystem funding; and investment products now integrate staking—Grayscale added staking for Ether ETFs, and BlackRock launched the iShares Staked Ethereum Trust (ETHB), combining spot Ether exposure with staking-based yield.
Ether traded around $2,164 at last look, up roughly 4.6% over the past year but well below mid-2025 highs above $4,000.
