BitMine Immersion Technologies acquired 27,562 ETH over the prior week, increasing its holdings to 5,983,940 tokens, or about 4.9% of the 122.1 million-token supply. The company said its crypto, cash and equity holdings totaled $17.1 billion as of September 20, including 212 Bitcoin, $714 million in cash and marketable securities, a $180 million stake in Beast Industries and a $105 million stake in Eightco Holdings. BitMine said 5,067,309 ETH, worth $13.6 billion and representing 85% of its ether holdings, was staked at a 2.62% annualized seven-day yield. It projects annualized staking revenue of roughly $357 million, rising to $421 million once the holdings are fully deployed through its MAVAN staking platform. The purchase extends weekly buying that began when BitMine launched its ETH Treasury Strategy on June 30, 2025, and leaves the company close to its stated 5% supply target, which it calls the "alchemy of 5%".
