Key takeaways

  • BitMine reported a third consecutive smaller weekly Ethereum purchase: 12,532 ETH for the week ended October 11, down from 15,112 ETH in the prior week and 17,362 ETH before that.
  • The company's treasury now holds 6,028,946 ETH, equal to 4.9% of the 122.1 million ETH supply, valued at $2,544 per token using Coinbase prices.
  • Tom Lee said BitMine needs about 100,000 more ETH and described the accumulation program as largely done, while its weekly update still states purchases have continued since June 30, 2025.
  • Staking is becoming the main yield story: 5,067,309 ETH is staked, generating an estimated $336 million annual revenue at a 2.61% seven-day yield, with potential to reach $400 million if all ETH is staked.

What happened

BitMine said on Monday that it bought 12,532 Ethereum in the week ended October 11. The purchase was the third in a row of smaller weekly additions, following 15,112 ETH in the week ended October 4 and 17,362 ETH the week before that. The latest addition lifted BitMine's treasury to 6,028,946 ETH, or 4.9% of the 122.1 million ETH supply.

The company marked its ETH at $2,544 per token, using Coinbase prices. At that valuation, its crypto, cash and equity stakes total $16.2 billion. Its cash and marketable securities stood at $612 million, down from $643 million a week earlier, and the release gave no reason for the decline.

Chairman Tom Lee provided the clearest signal that the buying phase is nearing an end. In a video message whose transcript BitMine filed with the SEC on October 7, Lee said BitMine had built its position in 15 months during a bear market. He said the company needed about 100,000 more ETH and stated that BitMine is done stacking while a bull market starts. Monday's release still notes that BitMine has bought ETH every week since its treasury strategy began on June 30, 2025, but a forward-looking statements note cites management saying the company is largely finished buying ETH.

Market context

The numbers show a treasury strategy moving from accumulation to optimization. BitMine's staked ETH reached 5,067,309, or 84% of its ether. Lee projected $336 million a year in revenue from that staked ether, based on a 2.61% seven-day yield, and said the total could rise to $400 million once all of the company's ether is staked. That puts staking yield, rather than the pace of weekly purchases, at the center of the next phase.

The capital structure also adds a funding dimension. BitMine raised money through 9.5% perpetual preferred stock, which trades as BMNP. The company had planned the offering to fund more Ethereum buying, among other uses. It sold 3.5 million preferred shares at $80 each on June 10. Those shares last closed at $99.53, and Lee put their current yield at 9.56%.

BitMine's share repurchase history gives another clue about management priorities. Lee said the company started buying back its own shares on July 14, when it repurchased 21 million shares for $350 million. The program completed on August 17, and none of the weekly updates since then has reported a repurchase.

Why it matters

For readers, the shift matters because it changes what can be measured and compared. If BitMine is largely finished buying ETH, the weekly purchase figures may lose explanatory power. The more relevant metrics become staking coverage, yield assumptions, cash levels and how the company manages its capital. The 5% supply target, which Lee said in May would be reached in late 2026 instead of mid-July, also anchors expectations: 6,028,946 ETH is close to that target, and the roughly 100,000 ETH gap described by Lee implies the remaining accumulation is modest relative to the treasury already built.

The staking projection also highlights sensitivity to yield levels. The $336 million annual revenue estimate rests on a 2.61% seven-day yield, and the $400 million figure depends on moving from 84% staked to all ether staked. Those are management projections, not outcomes. The release does not explain the decline in cash and marketable securities, leaving a gap in the short-term liquidity picture.

The preferred stock detail matters because the funding source was tied to Ethereum buying. BMNP trades above its $80 issuance price at $99.53, with a current yield described by Lee at 9.56%. If BitMine slows or stops ETH purchases, the original use of proceeds and the company's ongoing capital needs may be evaluated differently.

What to watch

The next weekly updates will show whether BitMine continues buying ETH despite Lee's statement that stacking is largely done. The release already says purchases have continued every week since June 30, 2025, so any interruption would be a clear change.

Another watchpoint is staking. The company holds 5,067,309 ETH staked, or 84% of its ether. Progress toward all ETH being staked would test the $400 million revenue projection, while changes in the 2.61% seven-day yield would affect the $336 million estimate.

Cash and marketable securities also deserve attention. They fell to $612 million from $643 million without an explanation in the release. Repeated declines, or a stabilization, would shape how much flexibility BitMine has outside its crypto holdings.

Finally, BMNP and share repurchases remain part of the story. The preferred stock last closed at $99.53 after its June 10 sale at $80, and the company has not reported a repurchase since the July 14 to August 17 program. Together, those items indicate whether BitMine is reallocating capital or simply winding down its buying phase.
