BitMine Immersion Technologies

Updated 2026-10-03

What it is

BitMine Immersion Technologies (NYSE American: BMNR) is a Las Vegas-based company, incorporated in 2019, that in June 2025 pivoted to an Ethereum corporate treasury strategy under Executive Chairman Thomas "Tom" Lee. It is now the world's largest corporate holder of ETH and runs an institutional staking operation called MAVAN to generate staking income on its holdings.

Why it matters lately

BitMine has pursued a publicly stated goal, dubbed the "Alchemy of 5%," of accumulating 5 percent of total ETH supply. As of September 27, 2026, the company held about 6.0 million ETH (roughly 4.9 percent of the ~122 million ETH supply), with total crypto, cash, marketable securities and other holdings of about $17.2 billion, and it has also run a $4 billion share buyback program retiring shares since July 2026.

Asymmetric Analytics view

Inference (AA): BitMine's accumulation pace and staking scale make it a bellwether for corporate-treasury demand for ETH and for institutional validator concentration on the Ethereum network.
