BitMine resumes stock buybacks and reports 5.23 million ETH staked

What happened

BitMine Immersion Technologies has restarted buying back its own stock, according to CryptoPotato, which reported that the company purchased 2.04 million shares last week at an average price of $22.48. The repurchase was BitMine's first reported buyback since mid-August. For 2026, the company has now repurchased 22.9 million shares for $399.6 million, at an average of $17.48.

The company also updated its Ethereum position. As of October 25, BitMine reported 5,227,037 ETH staked through its MAVAN platform and outside partners. Its total treasury rose by 10,452 ETH during the week to 6,051,933 ETH. That weekly addition was smaller than the 12,535 ETH added a week earlier and the smallest since the week ended August 16, CryptoPotato reported. BitMine said the holdings represent about 4.95% of the 122.2 million ETH in circulation, short of its 5% target.

In an October 26 SEC update cited by NewsBTC, BitMine put its combined crypto, cash, marketable securities and other investments at roughly $15 billion. The company valued its ether at $2,356 per token using Coinbase prices. Cash and marketable securities fell to $514 million, the fifth consecutive weekly decline from $714 million on September 20. BitMine also holds 215 bitcoin, a $180 million stake in Beast Industries and a $76 million position in Eightco Holdings.

Why it matters

The buyback and staking disclosure point to two parts of BitMine's strategy. Repurchases can reduce shares outstanding, but shareholders own equity in an enterprise with expenses, managers and capital-allocation choices, not a fixed claim on a set number of ether tokens. NewsBTC noted that the share price may reflect premiums or discounts to asset values as well as expectations about future operations.

The staking position adds operational exposure. BitMine is not simply holding ether; it participates in Ethereum's validator economy through MAVAN and partners, which brings lockup considerations and protocol-dependent reward and penalty mechanics. At this scale, custody, withdrawal controls, validator uptime and counterparties are material. NewsBTC also noted that published staking values should not be treated as an unconditional cash balance available to shareholders.

What the data shows

The latest disclosures include 2.04 million shares repurchased last week at an average of $22.48; 22.9 million shares repurchased in 2026 for $399.6 million at an average of $17.48; 6,051,933 ETH held; 10,452 ETH added during the week; 5,227,037 ETH staked; a 4.95% share of 122.2 million ETH in supply; $15 billion in combined crypto, cash and equity stakes; $514 million in cash and marketable securities; 215 bitcoin; a $180 million Beast Industries stake; and a $76 million Eightco Holdings position. Lee estimated annualized staking revenue at $318 million on the ether staked at the time, and $368 million if the treasury were fully staked at a 2.58% seven-day yield.

Background

BitMine completed its earlier buyback program on August 17, according to Chairman Tom Lee in an October 7 video message cited by CryptoPotato. Lee said the company intends to repurchase shares accretively when management believes they are relatively undervalued, subject to market conditions and its existing authorization. CryptoPotato noted that repurchase plans now appear in the release's forward-looking statements note, unlike the prior week's note. The staking figure had been frozen at 5,067,309 ETH for almost three months before the latest update, and BitMine's ether purchases have continued for almost a year and a half.

What is still unclear

The reports do not provide a full reconciliation of how much of the weekly ETH increase came from purchases versus staking rewards, nor do they give the current share count needed to calculate per-share ether exposure. NewsBTC said future filings can help separate changes attributable to new purchases, staking rewards, token prices and financing or repurchases.

What to watch

Subsequent SEC filings may clarify share count, buyback pace and the composition of the ether treasury. Changes in the staked balance, cash reserves and staking economics are also key items to watch. NewsBTC cautioned that the report confirms continued concentration in Ethereum but does not guarantee a favorable outcome if ether declines or staking economics change.
