Bitmine Nears 5% ETH Cap, Ending a Major Buying Run
Bitmine is nearing its 5% ETH holding cap, a shift that could remove a major source of demand for Ethereum. Chair Tom Lee said the company will stop buying once it reaches the limit. As of 4 October, Bitmine held 6,016,414 ETH, about 4.9% of supply, leaving less than 100,000 ETH to acquire. Its recent buying pace could take it to the cap in around six to seven weeks, and purchases have absorbed roughly 72% of newly issued ETH. Lee said Bitmine will not need to raise more funds for ETH purchases after reaching the cap. The company may sell staking rewards to stay within the limit, potentially around 80,000 ETH a year, but says it does not need to sell its core holdings. Meanwhile, US spot ETH ETFs recorded eight consecutive trading days of net outflows from 29 September, totalling about $641 million. Bitmine’s remaining purchases may support ETH demand in the short term, but their eventual end could leave ETF flows, staking demand and other institutional buyers more influential. If replacement buyers do not emerge, ETH could face weaker demand and greater volatility; a price decline is not guaranteed.
Bearish
The overall implication for ETH is bearish because Bitmine has been a large and consistent buyer, and its purchases have recently absorbed about 72% of newly issued ETH. Once the company reaches its 5% cap, that source of demand will end. This risk is more notable while US spot ETH ETFs have recorded sustained net outflows, leaving fewer clear sources of replacement buying. In the short term, Bitmine’s remaining purchases—potentially up to 100,000 ETH over the coming weeks—could provide support and limit the immediate impact. Over the longer term, however, the market may be more sensitive to ETF flows, staking demand and other institutional accumulation. Selling staking rewards to remain under the cap could also add some ETH supply, although Bitmine says it does not need to sell its core holdings. The cap does not guarantee a price decline: new institutional demand or a turnaround in ETF flows could offset the lost buying. But if such demand does not emerge, traders may price in weaker structural demand and greater volatility.
