BitMine

Originally a Las Vegas-based Bitcoin mining firm founded in 2021, BitMine Immersion Technologies began to stockpile Ethereum's cryptocurrency after a 2025 pivot in corporate strategy. Tom Lee, the Fundstrat cofounder and well-known Wall Street personage, became BitMine's chairman as part of that pivot. Chi Tsang is the CEO.

BitMine has since grown to become the largest corporate holder of Ethereum and holds more than 4% of all tokens in circulation, worth nearly $11 billion. The company projects annualized staking revenue of roughly $258 million. In January 2026, the company made a $200 million equity investment in Beast Industries, the holding company of YouTube influencer Jimmy Donaldson, better known as MrBeast.
