The annual filing illustrates the earnings volatility created by BitMine’s decision to build one of the world’s largest corporate cryptocurrency positions. That exposure has continued growing since the fiscal year closed: BitMine said this week that its holdings had reached 6,070,092 ETH, equivalent to approximately 4.97% of Ethereum’s supply.
How Much of BitMine’s Loss Was Driven by Ether?
Almost the entire annual loss came from changes in the market value of BitMine’s digital assets rather than cash leaving the business. The company recognized $6.229 billion of unrealized fair-value losses during fiscal 2026 as cryptocurrency prices declined.
At August 31, BitMine held 5,901,837 ETH valued at $14.56 billion, along with 211 bitcoin worth $16.6 million. Its total digital-asset position was carried at approximately $14.58 billion.
The accounting treatment means changes in cryptocurrency prices flow directly through earnings. BitMine warned that fluctuations in ETH are therefore likely to continue producing substantial volatility in reported profit, shareholders’ equity and its overall financial condition.
The exposure has only increased since year-end. BitMine’s latest disclosure puts its treasury at 6.07 million ETH, leaving it roughly 40,000 ETH below the 5% supply level that Lee has said will mark the end of the company’s accumulation program.
Investor Takeaway
The $6.3 billion loss is primarily a mark-to-market result rather than an equivalent cash loss. But with nearly 5% of Ethereum’s supply now on its balance sheet, movements in ETH increasingly dominate BitMine’s reported financial performance.
Can Staking Revenue Offset Treasury Volatility?
BitMine generated $124.8 million of revenue during fiscal 2026, up sharply from $6.1 million a year earlier as the business shifted away from bitcoin mining and toward Ethereum treasury management and blockchain infrastructure.
Staking and validation produced $121.4 million, or about 97% of total revenue. Mining contributed just $1.4 million, while leasing and consulting accounted for most of the remainder.
The revenue base is therefore becoming more recurring, but it remains small relative to changes in the value of the ETH treasury. A $6.23 billion unrealized asset loss was more than 50 times total annual revenue.
Staking income is itself exposed to both ETH prices and network yields. BitMine recently reported more than 5.2 million ETH deployed into staking, although falling staking yields and lower ether prices have reduced the dollar value of projected rewards.
Investor Takeaway
Staking provides BitMine with income from assets it already holds, but current revenue levels are nowhere near large enough to neutralize multi-billion-dollar changes in treasury value. ETH price exposure remains the dominant financial variable.
How Did BitMine Finance Its Ethereum Purchases?
BitMine relied heavily on equity markets during the fiscal year. It sold 395.1 million common shares through its at-the-market program, generating $13.20 billion in gross proceeds and approximately $12.94 billion after issuance costs.
The company said those funds were used primarily to acquire ETH, invest in its portfolio and support working capital and Ethereum-related initiatives.
At the same time, BitMine repurchased 20.8 million shares for $353.8 million at an average price of $17 per share under its $4 billion buyback authorization. The combination means BitMine issued far more equity than it retired as it funded its treasury expansion.
That capital structure is central to the strategy. BitMine can continue increasing ETH per share when it can raise equity on attractive terms, but heavy issuance can also dilute existing shareholders if the value created by new crypto purchases does not exceed the cost of the added shares.
What Happens When BitMine Reaches 5% of Ethereum?
BitMine launched its Ethereum treasury strategy in June 2025 and has continued purchasing ETH almost every week. Lee has since described 5% of Ethereum’s supply as a firm accumulation ceiling rather than a milestone after which buying will automatically continue.
Lee said in October that BitMine would stop accumulating once it reached the 5% threshold. With the company now at approximately 4.97%, the end of that buying program is approaching.
That would change the investment case. Once accumulation stops, attention is likely to move away from weekly ETH purchases and toward staking returns, capital allocation, the market value of the treasury and whether BitMine shares trade above or below the value of the assets backing them.
Investor Takeaway
BitMine’s annual results show the trade-off behind its treasury strategy: enormous ETH exposure creates substantial upside when ether rises but equally large accounting losses when prices fall. Reaching the 5% cap will make staking economics and management of the existing treasury more important than continued accumulation.
