BitMine Immersion Technologies, the world's largest corporate holder of Ethereum, will cease buying the asset once its holdings reach 5% of the total circulating supply. Chairman Tom Lee announced the strategic cap on Wednesday at the Token2049 conference in Singapore, stating the company is roughly 100,000 ETH away from reaching its target.
- BitMine Treasury Holdings: 6,016,414 ETH as of October 4, representing approximately 4.9% of total ETH supply.
- Remaining Purchase Target: Approximately 89,000 ETH to 100,000 ETH, requiring an estimated $230 million at current market prices.
- Accumulation Timeline: Initiated on June 30, 2025, at prices near $2,500 per token, scaling to 6 million tokens over 15 months.
- Staking Yield: 5.07 million staked ETH continues to generate approximately $363 million in annual yield.
Strategic Cap on Treasury Accumulation
BitMine began its aggressive accumulation strategy on June 30, 2025, when ETH was trading around $2,500. Over the following 15 months, the company expanded its balance sheet to 6,016,414 ETH, which accounted for 4.9% of the asset's circulating supply as of October 4. With ETH currently trading at $2,581, acquiring the final 89,000 ETH necessary to reach the 5% threshold will require approximately $230 million.
Tom Lee noted that reaching the 5% cap will allow BitMine to discontinue capital-raising efforts previously dedicated to funding token purchases. The announcement signals an end to one of the market's largest structural buying programs, while institutional positioning shifts across products like Ethereum network solutions and funds.
Historical Buying Impact and Market Counterforces
BitMine's buying activity previously had a dramatic impact on price momentum. In August 2025, the firm added 1.1 million ETH to its balance sheet, marking the largest single-month corporate addition that month according to VanEck. During that period, ETH surged 15.8%, peaking near $4,953 amid broader institutional demand that brought $4 billion in monthly Ethereum fund inflows.
However, persistent buying throughout 2026 failed to prevent severe drawdowns. By June 2026, ETH fell 44% year-to-date below $2,000, leaving BitMine's 5.41 million ETH position approximately $9 billion below its purchase basis. Recent institutional flows have leaned net-negative, with US spot Ethereum ETFs suffering $408 million in net outflows over six days per SoSoValue data. This outflow represents roughly 152,000 ETH, eclipsing BitMine's recent weekly purchase pace of 15,112 ETH even as wider market movements mirror shift trends in exchange reserve balances.
Why It Matters
BitMine’s decision to cap its treasury marks a critical transition point for corporate balance sheet strategies in crypto. By capping accumulation at 5%, BitMine shifts its core focus from balance sheet expansion to harvesting regular cash flow from its 5.07 million staked ETH, which yields $363 million annually. Without BitMine's steady weekly buy pressure, Ethereum's short-term price dynamics will rely far more heavily on spot ETF flows and decentralized network utility to absorb market supply.
