BitMine Shares Slip 7.1% Amid $1.1 Billion Selloff That Scrutinizes Ethereum Treasury Discount

BitMine Shares Slip 7.1% Amid $1.1 Billion Selloff That Scrutinizes Ethereum Treasury Discount

NORWALK, Connecticut, August 28, 2026, 19:55 (EDT)

  • BitMine ended the session at $23.80, falling 7.14%, with 51.39 million shares traded.
  • The drop wiped out roughly $1.10 billion in equity value.
  • The closing price on Friday suggested about a 3.2% discount compared to listed disclosed treasury assets.

BitMine Immersion Technologies (NYSE American: BMNR) dropped 7.14% on Friday, wiping out approximately $1.10 billion in market capitalisation. The fall outpaced Ether’s decline of about 3%.

The distinction is important as BitMine primarily acts as an Ethereum treasury in current trading. Its main financial support comes less from operating assets and the staking platform.

Shares ended the session at $23.80, having previously hit $23.75. Trading volume totaled 51.39 million, surpassing the 65-day average by 33%. The stock edged down a further 0.3% to $23.73 as of 18:46 EDT.

As of August 23, BitMine stated its ETH holdings stood at 5,847,611. The company also revealed it held 210 bitcoin, cash and securities totaling $308 million, along with two equity investments together worth $269 million.

According to Coinbase, ether was priced at around $2,438 late Friday. This puts the value of BitMine’s ETH at approximately $14.26 billion. Including the other reported assets, the combined total is estimated at $14.84 billion.

Investor measureFriday readingInterpretation

Other disclosed assets$577 millionIncludes cash, bitcoin, and a pair of investments
Implied discount3.2%Excludes effects of liabilities, tax and custody fees

The discount remains slight. A 1% fluctuation in Ether shifts the treasury’s marked value by approximately $143 million. On Friday, the drop in equity represented about 7.7% of the ETH reserves.

BitMine has allocated 5,067,309 ETH to staking, which accounts for 87% of its total assets. According to management, this current level of staking is expected to generate $330 million in annualized revenue. The reported seven-day annualized yield stood at 2.67%.

The resulting revenue may help balance certain holding expenses. Still, it accounts for just 2.3% of Friday’s marked ETH position. Daily swings in ether prices can surpass an entire year’s worth of staking returns.

The most recent quarter provides another reference point. As of May 31, BitMine listed $11.60 billion in stockholders’ equity and posted a quarterly loss of $83.6 million attributable to common shareholders.

The number of shares is also significant. MarketWatch reports 603.23 million shares outstanding, which is approximately 9.3% higher than the quarter’s diluted weighted average of 551.79 million.

Analyst coverage is limited, with MarketWatch listing just two ratings, making consensus comparisons less meaningful. Treasury math provides a clearer benchmark for valuation.

Risks: This calculation provides only an estimate, rather than net asset value. It does not account for liabilities, taxes, custody expenses, possible dilution, or daily fluctuations in cryptocurrency or private investment prices. If Ether sees a prolonged drop, the indicated discount could swiftly become a premium.

The following test is simple. Investors need to determine if staking income and treasury performance warrant a higher valuation than merely passing through. Friday’s 7.1% drop provided minimal room for mistakes.

Watch: The 3.2% discount is narrower than normal crypto volatility. It is not audited NAV and excludes liabilities, tax, custody costs, dilution and live changes in private investments. Sparse analyst coverage—two ratings—makes treasury sensitivity the cleaner near-term benchmark.
