BitMine Immersion Technologies (NYSE: BMNR) added 9,926 Ethereum tokens over the week ending August 16, according to a company disclosure. The purchase lifted the company's total ETH holdings to 5,815,164 tokens, a position valued at roughly $11 billion.

Alongside the acquisition, BitMine continued to stake the bulk of its treasury and to repurchase its own shares, while its stock advanced on the New York Stock Exchange. The update also underscores how the company is combining balance-sheet accumulation with staking and buybacks as it works toward its stated ETH concentration target.

Shares closed at $18.73 on Monday, a gain of 3.68% for the day, and added another 0.37% in after-hours trading. Trading volume came in near 30.95 million shares, slightly below the average volume of 32.51 million shares. Over the past year, the stock has traded between $12.80 and $65.60.

Staking Generates Steady Yield

BitMine has staked 5,067,309 ETH, which makes up about 87% of its total holdings. At the company's reference price, those staked tokens were worth close to $9.6 billion.

The company laid out its latest treasury figures in a post on X dated August 17, 2026:

The staking program produced a seven-day yield of 2.61%, and based on that rate BitMine projects annualized staking revenue of $250 million. The company noted that the figure is a projection rather than a guaranteed return, and that staking rewards can shift based on network activity and validator participation.

Buyback Program Continues

BitMine also continued its stock buyback program during the same week, repurchasing 1.7 million shares and bringing total repurchases since July 1 to more than 20.8 million shares. The board approved the buyback program, worth up to $4 billion, in April. Chairman Thomas Lee described the ongoing repurchases as the largest ever carried out by a crypto treasury company.

Closing In On The 5% Target

BitMine refers to its goal of owning 5% of all ETH as the "Alchemy of 5%." Based on an estimated supply of 120.7 million tokens, that target equals about 6.035 million ETH. The company's current holdings put it at roughly 96% of the goal — its Ethereum stack now equals about 4.8% of ETH's total supply — leaving about 219,836 more tokens to be acquired to reach the full target.

BitMine has purchased ETH every week since starting its treasury strategy on June 30, 2025. That streak has now lasted about 14 months without a break.

Portfolio Composition And Ranking

The company's total portfolio, including crypto, cash and other holdings, was valued at $11.4 billion. That figure includes 210 Bitcoin, $78 million in cash, and stakes in Beast Industries and Eightco Holdings.

BitMine's Ethereum treasury is currently the largest in the world, and the company ranks as the second-largest crypto treasury overall, behind Strategy Inc, which holds 840,447 Bitcoin worth close to $58 billion.

Lee has linked the company's strategy to the ETH-to-BTC price ratio, which sits at 0.02994, and has pointed to the rising use of Ethereum for tokenization and AI applications as a reason for the company's continued buying.

BitMine has not set a public deadline for reaching its 5% supply target. Its next weekly update will show whether the buying streak continues.
