BitMine Immersion Technologies, chaired by Tom Lee, has launched its proprietary Made in America Validator Network (MAVAN), positioning it as an institutional-grade Ethereum staking platform. The former bitcoin miner, which is the world’s largest ETH holder with over 100,000 staked tokens, also disclosed its total holdings now exceed 4.66 million ETH, contributing to an approximate $11 billion portfolio that includes cash, Bitcoin, and stakes in other companies.
BitMine Immersion Technologies has announced the launch of its proprietary Made in America Validator Network (MAVAN). According to a press release, the platform is designed as a premier staking destination for institutions with a focus on security and resilience.
The network combines US-based infrastructure with a globally distributed architecture to support clients worldwide. MAVAN was initially developed to support BitMine’s own ETH treasury but will now expand to serve institutional investors and partners.
Tom Lee commented on the development, stating the platform’s strategic importance. “MAVAN represents a critical step in our vision to build one of the leading staking and on-chain infrastructure platforms globally,” he said.
Lee further noted that because BitMine is the largest owner of Ethereum, MAVAN will shortly become the world’s largest Ethereum staking platform. The company plans to expand across additional proof-of-stake networks and develop other on-chain infrastructure through 2026.
In a separate update, BitMine increased its Ethereum holdings to 4,660,903 tokens. The company’s latest portfolio, shared on March 23, 2026, also includes 196 Bitcoin and significant stakes in other firms.
Its total holdings are valued at approximately $11 billion, which includes just over $1 billion in cash. This portfolio includes a $200 million stake in Beast Industries and a $95 million stake in Eightco.
