Key Highlights

  • BitMine Immersion Technologies (NYSEAMERICAN:BMNR) extended its run of ether purchases into Tuesday, October 20, 2026, lifting its holdings to about 4.9% of the token's supply, as reported by Tradingpedia.
  • Chairman Tom Lee has set a goal of owning 5% of all ether, so the company is about 98% of the way to that target on simple arithmetic using the reported share.
  • The same report said ether was holding support, a price zone where buyers have stepped in before, although the precise level and purchase size were not captured in the summary available.
  • The buying continued after a week in which bitcoin dipped to USD 81,000 and spot crypto ETFs saw outflows, so BitMine remained a steady buyer while other investors cut exposure.

What BitMine Has Built

BitMine Immersion Technologies (NYSEAMERICAN:BMNR), the ether treasury company chaired by Fundstrat co-founder Tom Lee, kept buying ether into Tuesday, October 20, 2026. Its holdings now equal about 4.9% of the token's supply, Tradingpedia reported, while ether held a support zone. With circulating supply of roughly 120 million tokens, 4.9% would be close to 5.9 million ether, simple arithmetic on an approximate supply figure rather than a company disclosure. The company has bought ether every week since it adopted its treasury strategy in mid-2025, making it the largest corporate holder of the token. Its stated goal is 5% of supply, so the remaining gap is about 0.1 percentage point, or roughly 120,000 ether on the same approximate arithmetic.

How an Ether Treasury Company Works

BitMine (NYSEAMERICAN:BMNR) raises money mainly by selling new shares, often through at-the-market offerings, which let a company sell stock gradually at prevailing prices, and uses the cash to buy ether. When its shares trade above the value of the ether held per share, each sale adds more ether per share than before, which rewards existing holders. When that premium shrinks, issuing stock becomes less useful. Ether can also be staked, meaning locked to help validate the network in return for rewards, which gives the treasury an income stream that bitcoin holders lack. Holding nearly 5% of a token also brings concentration: the company becomes a large price setter, and any future selling would be closely watched by the market.

Risks and What to Watch

The first risk for BitMine (NYSEAMERICAN:BMNR) is the ether price, because the shares act as a geared claim on the token through the premium. A second is that the premium to holdings narrows, which would slow purchases once the 5% goal is reached or before it. A third is index treatment: MSCI approved rules on October 16 that could eject digital asset treasury companies such as Strategy and Metaplanet, and similar scrutiny could extend to other treasury firms, an inference rather than a stated plan. Investors should watch the next weekly holdings update, which the company has typically issued on Mondays, around Monday, October 26, the Federal Reserve decision on Wednesday, October 28 and MSCI changes after Monday, November 30, 2026.

Where Things Stand

The answer is that BitMine (NYSEAMERICAN:BMNR) is within about 0.1 percentage point of its 5% target, so the question shifts from how much it buys to what it does after reaching the goal. Buying could slow, staking income could matter more and the share premium will decide whether new stock sales still add value. The next catalysts are the weekly update around Monday, October 26, the Fed decision on Wednesday, October 28 and MSCI changes after November 30. Holdings targets can change, and this is not investment advice.
