Key takeaways

  • BitMine Immersion Technologies bought 12,532 ETH in the week to October 11, 2026, taking its treasury to 6,028,946 ETH, or 4.9% of Ethereum's 122.1 million token supply.
  • The buy was the third smaller weekly addition in a row, after 15,112 ETH in the week to October 4 and 17,362 ETH the week before.
  • Chairman Tom Lee said in an October 7 SEC-filed video transcript that BitMine needs about 100,000 more ETH to reach its 5% target, then it is done stacking.
  • Staked holdings: 5,067,309 ETH, 84% of holdings; cash and marketable securities: $612 million; other assets: 214 BTC, $180 million in Beast Industries, $85 million in Eightco Holdings.

What happened

Cryptopotato and Decrypt covered the October 12, 2026 update. Decrypt reported the Monday release valued the purchase at about $31.9 million, using the company's $2,544 ETH valuation price. Cryptopotato highlighted the shrinking buys and the $643 million cash base from a week earlier; Decrypt emphasized Lee's comments and the wider balance sheet.

Lee did not present the smaller purchases as a strategy change. He said BitMine built its position over 15 months during a bear market and that the remaining gap is roughly 100,000 ETH. In the same update, management described itself as largely finished buying ETH, even as the release recorded another weekly addition. The accumulation program began on June 30, 2025.

The report also restated staking economics. Lee estimated about $336 million in annualized staking revenue at a 2.61% seven-day yield on the staked portion, rising to $400 million once the entire treasury is deployed. Because only 84% of the ether is staked, that full yield figure remains a future condition, not a current result.

Market context

At 4.9% of supply, BitMine is near the 5% threshold Lee calls the Alchemy of 5%. Recent weekly buys of 12,532 to 17,362 ETH could close the remaining 100,000 ETH gap in weeks; a stop would make the target a 2027 story.

Lee predicted the biggest bull market ever seen, citing tokenization, generational wealth transfer, treasury-firm absorption and AI agents using crypto wallets.

The update also showed the company is no longer only an ETH accumulator. Its total crypto, cash and investment holdings were $16.2 billion. Outside ETH, it holds 214 BTC, a $180 million stake in Beast Industries and $85 million in Eightco Holdings.

Capital structure details appeared in only one report. Lee said BitMine began repurchasing its own shares on July 14, bought 21 million shares for $350 million and completed the program on August 17. No weekly update since then has reported a repurchase. BitMine also raised money this year through BMNP, a 9.5% perpetual preferred issue sold at $80 per share on June 10. Lee put its current yield at 9.56% and the last close at $99.53.

Why it matters

The shift is from accumulation to deployment. As one of the largest single ETH holders, slowing purchases removes a steady, price-insensitive buyer, especially if treasury firms are absorbing supply.

The practical question shifts from weekly ETH purchases to staked revenue, ETH market value and balance-sheet performance. The $400 million staking target depends on deploying the remaining 16% of ETH and on yields holding.

The unexplained $31 million cash decline is the other open item. A treasury firm buying assets while relying on preferred stock and buybacks invites questions about cash use; the release gave none.

A reporting gap remains: Cryptopotato highlighted shrinking purchases and cash decline; Decrypt added the bull-market rationale and other holdings. Both showed $16.2 billion, but only one broke out the composition.

What to watch

The next weekly update will show whether BitMine keeps buying, buys smaller amounts or stops. A 12,000 to 17,000 ETH pace closes the 100,000 ETH gap quickly; a pause makes the 5% target a 2027 story.

Watch for any new share repurchase disclosure. No report would confirm the August 17 close; a new one would reopen capital allocation questions between ETH, shares and preferred obligations.

Moving from 5,067,309 ETH staked to the full 6,028,946 ETH treasury makes the $400 million estimate testable, if the 2.61% seven-day yield framework and execution remain stable.

The cash line still needs explanation. Later reports should show whether it funded purchases, staking operations or portfolio positions; if it reflects a drawdown, the company must address it beyond a Monday release.
