Bitmine ETH Holdings Reach 5.21 Million Tokens as Total Crypto Holdings Hit $13.4 Billion
Bitmine Immersion Technologies disclosed on May 17 that its Ethereum (ETH) holdings have reached 5.21 million tokens, putting the company’s total cryptocurrency and cash holdings at $13.4 billion. The disclosure, issued via PR Newswire, places Bitmine ahead of every other publicly listed company accumulating ETH as a treasury asset.
The company holds more than five times the Ethereum of its nearest corporate peer, a gap that has widened sharply since the accumulation program began.
Bitmine ETH Holdings Cross 5.21 Million Tokens
Bitmine Immersion Technologies (BMNR) published its May holdings update Saturday, showing 5.21 million ETH on its books alongside combined crypto and cash reserves of $13.4 billion. At Ethereum’s current trading level near $2,100, the ETH position alone is valued at roughly $10.9 billion.
The company said total on-chain asset holdings continue to exceed user deposit obligations, a figure it cites as evidence of conservative financial management.
The disclosure does not detail the average acquisition cost of the ETH stack or the specific breakdown between cryptocurrency and cash within the $13.4 billion figure. Bitmine said the reserves reflect its “user-first philosophy,” language it uses consistently in monthly reserve communications.

What Bitmine Does
Bitmine Immersion Technologies is a publicly traded company that originally focused on cryptocurrency mining using immersion cooling technology, a method that submerges mining hardware in dielectric fluid to manage heat more efficiently than air-cooled setups.
The company has since pivoted toward Ethereum accumulation as a core treasury strategy, drawing comparisons to the bitcoin acquisition model pioneered by MicroStrategy (MSTR).
Bitmine’s approach differs in that it focuses exclusively on Ethereum rather than Bitcoin. The company argues ETH’s proof-of-stake consensus mechanism, which replaced the energy-intensive proof-of-work model in September 2022, gives it structural advantages as an institutional treasury asset, including staking yield and alignment with ESG-focused capital.

Context and Prior Accumulation
Bitmine’s ETH holdings have grown substantially through the first half of 2026.
The company crossed the 4 million ETH threshold in an earlier disclosure, and the May update represents an increase of more than 1.2 million tokens since that prior figure. The pace of accumulation has accelerated even as Ethereum’s price has declined from its 2024 highs, suggesting Bitmine is treating price weakness as a buying window rather than a signal to reduce exposure.
Corporate treasury buying of Ethereum remains a minority practice compared to Bitcoin accumulation.
Fewer than ten publicly listed companies hold ETH as a primary treasury reserve, making Bitmine’s position structurally distinct within the corporate crypto landscape.
What to Watch
Investors and analysts will watch whether the Ethereum price recovery materializes before Bitmine’s next monthly disclosure. A sustained ETH rally above $2,500 would push the company’s total crypto holdings meaningfully above the $13.4 billion figure.
Conversely, further ETH weakness tests the sustainability of the accumulation program and raises questions about dilution risk if Bitmine continues raising capital to buy tokens at depressed prices.
