TL;DR

  • Tom Lee said Bitmine will stop accumulating Ethereum at 5% of supply, turning its treasury target into a stated ceiling.
  • Bitmine reported 6,016,414 ETH as of October 4. Lee says roughly 100,000 ETH remains; a calculation using the issuer's rounded supply gives 88,586 ETH.
  • No exact stopping date or detailed staking-reward policy was disclosed. Ending purchases does not mean selling the existing treasury.

CASABLANCA, October 7, 2026

Bitmine chairman Tom Lee said October 7 the company will stop buying Ethereum once it holds 5% of the token’s supply, leaving roughly 100,000 ETH to acquire as a major corporate buyer approaches the end of its accumulation campaign.

The statement turns Bitmine’s longstanding treasury target into a stated ceiling. It describes a future stopping point, rather than confirming an immediate halt or a sale of the company’s existing Ethereum holdings.

Ether finished October 6 at $2,697.98, down 0.44%, with a daily range of $2,684.45 to $2,723.56, according to Investing.com’s historical table. Those completed-session figures precede the announcement and do not measure its market impact.

In the October chairman’s message transcript furnished to the SEC, Lee said, “we need to get about 100,000 more ETH, and that’s about it.” Bitmine’s investor-relations summary explicitly describes the 5% level as a hard cap.

That changes the emphasis from the preferred-funded buying reported in June. The new development is management’s stated endpoint for purchases, rather than another routine increase in the treasury balance.

Removing a recurring buyer could change one source of Ethereum demand. It would not, by itself, release Bitmine’s existing holdings into the market or establish the direction of ETH prices.

Bitmine’s 5% Ethereum target becomes a buying cap

Lee discussed the ceiling at Token2049 in Singapore, according to Decrypt’s October 7 report. The company’s official investor-relations page also published its October message and described approximately 100,000 ETH remaining.

A separate October 7 Form 8-K records publication of Lee’s presentation, video transcript and related release. The material was furnished under Regulation FD, rather than treated as filed for the specified securities-law liability purposes.

The disclosure establishes management’s public position. It does not establish an exchange order, an executed final purchase or a binding rule that future boards cannot change. Neither the exact stopping date nor a detailed implementation policy was disclosed.

The distinction separates two different flows. Purchases transfer ETH into the company’s treasury. Holding already-acquired ETH preserves its existing exposure. Stopping the first activity does not automatically unwind the second.

The policy also does not cap Ethereum’s own supply or change network issuance. It is a corporate allocation limit expressed relative to that supply, so the denominator matters alongside the number of tokens Bitmine owns.

The immediate market question is how much buying would disappear and when. A holding total describes accumulated exposure, whereas weekly acquisition figures describe incremental demand. Treating the entire treasury balance as a new order would overstate the purchasing flow potentially affected by the decision.

6.02 million ETH leaves an approximate purchase gap

Bitmine’s October 5 treasury release reported 6,016,414 ETH as of October 4 at 6:30 p.m. ET. It described that position as 4.9% of a 122.1 million ETH supply and said it acquired 15,112 ETH over the preceding week.

Using that rounded supply figure, 5% equals 6,105,000 ETH. Subtracting the disclosed holding leaves 88,586 ETH. That is an illustrative calculation from the issuer’s inputs, rather than a replacement for Lee’s approximate 100,000-token description.

At the release’s $2,726 valuation price, those amounts would represent about $241.5 million and $272.6 million respectively. Neither is an announced spending budget, committed financing amount or current quote for executing the remaining purchases.

Supply can change, while purchases and staking rewards can alter the numerator. Reporting cutoffs also differ. A rounded percentage is therefore insufficient to determine the exact day the company reaches its ceiling.

The September 28 release listed 6,001,302 ETH as of September 27. Its difference from the October 4 balance matches the latest 15,112-token purchase figure.

If that weekly pace stayed unchanged, Lee’s approximate gap would represent about 6.6 weeks of purchases. That conditional arithmetic does not establish a November deadline: the company has not promised a fixed acquisition rate, and the supply target can move.

The contrast with Metaplanet’s recent sale and repurchase test is useful. Treasury companies can reach different decisions about adding exposure and maintaining liquidity; Bitmine’s ceiling should not be read as a sector-wide buying policy.

The existing position remains sensitive to ETH prices. At the October 6 close, a 1% price change applied to 6,016,414 tokens would change their gross market value by approximately $162.3 million. That illustration excludes hedges, liabilities and other assets and is not a reported company gain or loss.

It also does not establish Bitmine’s acquisition cost. The price used to value a treasury snapshot differs from the prices paid for individual purchases. Calculating unrealized profit or loss requires cost-basis information that the snapshot alone cannot supply.

Bitmine staking continues beyond the purchase decision

The October 5 update reported 5,067,309 staked ETH, about 84% of the company’s holdings. It projected $363 million of annualized staking revenue at the current scale and $431 million if its ETH were fully staked, using a 2.63% annualized seven-day yield.

Those are projections, rather than guaranteed receipts or reported full-year profit. Dollar values depend on ETH prices and operating conditions. A token reward also differs from cash available for expenses or preferred-stock dividends.

An annualized seven-day yield extrapolates a short observation period over a year. It does not show that the same rate will persist for twelve months, or that every token held is earning it. The distinction becomes more relevant as attention shifts from acquisitions to the performance of the existing treasury.

Ethereum’s staking withdrawal documentation distinguishes reward withdrawals from withdrawing a validator’s full balance. Exiting staking can involve a queue, so an asset held in the treasury is not necessarily immediately available for a sale or payment.

Purchases and staking rewards could consequently push the same percentage in different ways. The cited October disclosures do not explain whether Bitmine will sell rewards, retain them or periodically rebalance to maintain the ceiling.

Shareholders face another distinction. An equity investment gives exposure to the company’s assets, expenses and financing structure; it is not direct ownership of its wallets. The earlier Norwegian sovereign fund’s Bitmine stake illustrated that separation between company shares and ETH.

Alternative.me’s Fear & Greed Index stood at 71, labeled greed, against 73 yesterday. Its methodology is centered on Bitcoin, so it provides broad market context rather than an Ethereum-specific measure of this policy’s impact.

As of 19:05 UTC on October 7, the timing of the final purchases and treatment of staking rewards remained undisclosed. The next meaningful evidence will be an updated holdings report and explicit rules for maintaining the cap, rather than a rounded treasury milestone alone.

Frequently Asked Questions

Is Bitmine stopping Ethereum purchases now?

Tom Lee says purchases will stop when Bitmine reaches 5% of Ethereum supply. Its latest disclosed holdings are below that level. No exact stopping date was announced as of October 7, 2026.

How much Ethereum does Bitmine hold?

Bitmine reported 6,016,414 ETH as of October 4 at 6:30 p.m. ET, approximately 4.9% of the 122.1 million ETH supply figure used in its October 5 release.

How much ETH does Bitmine need to reach 5%?

Lee described roughly 100,000 ETH remaining. Using the issuer's rounded 122.1 million supply and disclosed holdings gives an illustrative gap of 88,586 ETH. Neither figure fixes a final purchase order because supply and holdings can change.

Does Bitmine's buying cap mean it will sell its Ethereum?

No sale of the existing treasury was announced in the cited October 7 disclosures. A cap on further purchases differs from liquidating existing holdings. Detailed rules for staking rewards and maintaining the percentage were not disclosed.

Will Bitmine still earn staking rewards after buying stops?

Stopping purchases does not itself stop staking. Bitmine reported 5,067,309 staked ETH and projected $363 million of annualized staking revenue in its October 5 update. That projection is variable and is not guaranteed cash income.
