BitMine (BMNR), an Ethereum treasury company, reported a $6.313 billion net loss for the fiscal year ended August 31, 2026, in its 10-K filing with the U.S. Securities and Exchange Commission. It had recorded a $349 million net profit in the prior fiscal year.
According to ChainCatcher, the loss was driven mainly by changes in the fair value of digital assets. BitMine recorded approximately $6.229 billion in unrealized digital-asset losses for the year, primarily because the fair value of ETH fell. Revenue was approximately $125 million, of which staking and validation contributed about $121 million, or roughly 97%.
At fiscal year-end, BitMine held 5,901,837 ETH and 211 BTC. Its ETH holdings had a cost basis of approximately $19.948 billion and a fiscal year-end fair value of approximately $14.559 billion.
A separate holdings update issued by BitMine on November 9 said that, as of November 8, 2026, its ETH holdings had risen to 6,070,092 ETH—approximately 4.97% of ETH supply—with 5,227,037 ETH staked. Those November figures are a later snapshot, not the fiscal year-end balance.
