BitMine's $6.3 Billion Ethereum Gap: $19.9B Spent, $14.6B on Hand

BitMine Immersion ended fiscal 2026 holding 5,901,837 ETH that cost $19.9 billion but was worth $14.6 billion at year-end prices — a $6.3 billion gap between purchase cost and market value, according to its annual filing. The former Bitcoin miner's Monday update put the value of its combined crypto, cash and equity holdings at $14.3 billion as of November 8, down from $15.4 billion at year-end.

The company's Ethereum stack grew sharply over the year. It held 1,874,927 ETH when the fiscal period began, meaning it added roughly four million ETH in twelve months. Buying the dip, it turns out, has a price tag.

What did the options book do?

The filing shows BitMine began selling ETH put options in the quarter ended February 28, 2026. Put sales pay a premium up front but expose the seller to losses if ETH falls below an agreed strike price.

That book, mostly put sales, lost a net $143.7 million over the year. The company held no open option contracts at year-end and said it may deploy similar strategies again — with a caveat. BitMine warned that option losses could hurt its ability to pay dividends on the 9.50% preferred stock offering it launched in June, as CryptoPotato reported.

What does this change for shareholders? A preferred dividend now sits downstream of an options program that has already bled nine figures once.

Where does the money come from?

Staking and validation supplied $121.4 million, about 97% of BitMine's total revenue. The company began staking its own ETH in November 2025. In March it bought Pier Two, an Australian staking provider, and folded the acquisition into MAVAN, the staking platform BitMine launched that same month.

So the operating model is now clear: park billions in ETH, stake it, harvest yield, and sell volatility on the side.

Costs crept up too. General and administrative expenses rose to $376.9 million from $361.1 million, driven mainly by ETH custody fees plus higher pay for staff and board members, the company said. When your balance sheet is four million ETH, simply storing it becomes a line item worth noticing.

What happens next?

The company has no open options exposure today, but management's stated willingness to resume put-selling keeps that risk live. Each new quarter brings a fresh decision on the strategy, and each ETH drawdown raises the odds the puts bite again.

Watch the next filing window. The interplay between staking income, dividend obligations on the 9.50% preferred, and any rebuilt options book will determine whether the $6.3 billion unrealized hole stays a paper mark or becomes an operating problem.
