Bitmine Immersion Technologies said it bought 28,086 ETH over the past week, extending an aggressive Ethereum treasury strategy that has positioned the Nasdaq-listed miner as one of the largest corporate holders of the asset, according to a company-issued disclosure attributed to chairman Thomas Lee.
The acquisition was announced on September 8, 2026 at 08:30 ET, with the buy described as accumulated over the prior week rather than executed in a single trade, per Bitmine's release distributed via PR Newswire. ETH is Ethereum's native asset, and Bitmine's disclosure frames the purchase as part of a continuing balance-sheet buildup rather than an opportunistic one-off.

Bitmine’s weekly ETH acquisition
28,086 ETH

Acquisition execution prices and exact expenditure were not disclosed.Source: Bitmine company announcement via PR Newswire.Lee said the company acquired the tokens over the past week, per the release, which is a management statement from an interested company representative rather than an independent audit. The disclosure does not name execution prices, counterparties, wallet addresses or transaction hashes, so the weekly buy cannot be converted into a precise dollar cost.

The company reported valuing its Ethereum stack at $2,495 per ETH, a Coinbase-referenced snapshot price used for holdings valuation, not a disclosed acquisition execution price. That distinction matters: the valuation basis reflects a point-in-time mark, while the actual cost of the weekly buy remains unpublished.

Independent reporting from Bitcoin.com News corroborated the weekly addition and the resulting balance, valuing the ETH alone at roughly $14.79 billion at the same $2,495 mark. That corroboration confirms the reported figures rather than auditing the underlying wallets.
As of September 7, 2026 at 2:00 PM ET, Bitmine reported holdings of 5,929,198 ETH, a total balance that dwarfs the weekly addition and reflects months of accumulation. The company's earlier disclosures, including a prior update showing 5.90 million ETH and $15.6 billion in total assets, trace the same upward trajectory.

This is the total balance, not the weekly purchase quantity.Source: Bitmine company announcement via PR Newswire.Of that stack, Bitmine reported 5,067,309 ETH staked as of September 7, generating a seven-day annualized staking yield of 2.61% and a projected $330 million in annualized staking revenue, according to the same disclosure. The yield is a recent observation and the revenue figure is a forward projection, not realized annual income.
Beyond Ethereum, the company reported 211 BTC and $593 million in cash and marketable securities, bundled into a combined crypto, cash, marketable securities and moonshot total of $15.7 billion, as detailed in the company's holdings breakdown. That headline figure is broader than the ETH balance and should not be read as the value of Ethereum alone.
The weekly buy sits against a soft spot market, with ETH trading near $2,524.81 as of September 12, 2026 UTC, down about 1.3% over 24 hours, with a market capitalization around $308 billion and daily volume near $10.4 billion. Those are current API snapshots, distinct from the September 7 company valuation, and no last-updated timestamp was returned.
A single reported acquisition, even one this size, does not by itself establish a broad institutional accumulation trend, and the disclosure supplies no execution venue or intraday timing to link the buy to any specific price movement. Corporate treasury demand for Ethereum echoes the equity-side positioning seen elsewhere, such as Ark Invest's recent bets on Block and Circle, but each disclosure must be weighed on its own evidence.
Broad sentiment remained tilted toward optimism, with the crypto Fear & Greed Index at 63, or "Greed," on the September 12 reading. That gauge measures market-wide mood and does not evidence any investor reaction specific to Bitmine's buy.
The announcement leaves several material gaps unresolved. Trade-level execution prices, exact expenditure, counterparties, wallet addresses and transaction hashes were not disclosed, so no on-chain trace confirms the buy independently.
How much ETH did Bitmine buy? Bitmine reported acquiring 28,086 ETH over the past week, attributed to chairman Thomas Lee in its September 8, 2026 announcement.
How much did Bitmine pay for the ETH? The company did not disclose an acquisition cost; it valued its holdings at a $2,495 per-ETH snapshot price, which is a mark, not the execution price of the buy.
How much ETH does Bitmine hold after the purchase? The company reported 5,929,198 ETH as of September 7, 2026 at 2:00 PM ET, a dated total disclosed the following day.
The next concrete triggers for holders and policy watchers are Bitmine's subsequent weekly holdings updates and any transaction-level or on-chain disclosure that would move the report from management statement to verifiable record.
