Bitmine bought another 17,362 ether, the company disclosed, pushing its total holdings past 6 million ETH. The firm's combined crypto, cash and other investments now sit at $17.2 billion.
The purchase leaves Bitmine holding more than 4.9% of ether's circulating supply — a position no other publicly listed treasury operation has come close to matching.
Past the 6 million mark
Crossing 6 million ETH is the headline number, but the 4.9% figure is the one that matters for anyone watching supply dynamics. Bitmine isn't nibbling at the edges of the ether market anymore. It's a systemically sized holder, and the gap between it and the next-largest corporate treasury has grown wide enough that comparisons are starting to feel pointless.
Tom Lee, who runs the firm, has been open about the strategy for months. Each disclosure has followed the same pattern: a chunk of ether, a treasury update, and a reminder that the company treats the token as a long-duration reserve asset rather than a trading position.
What $17.2 billion buys
The treasury total is a blended figure — crypto, cash and other investments rolled together. That's worth keeping in mind. Bitmine isn't sitting on $17.2 billion of ether alone; the ETH stack is the core, but the cash and side holdings give the firm room to keep buying without touching the token position.
That flexibility is the whole point. A treasury that can fund purchases from cash flow doesn't have to sell into weakness, and it doesn't have to tap credit markets when rates are unhelpful. Bitmine has structured itself so the ether accumulation can continue on its own schedule.
The supply question
Holding 4.9% of circulating ether puts Bitmine in rare territory. It's not a controlling stake, and it's not a threat to the network — but it does mean the firm's buying cadence is now a variable that traders watch. Every 17,000-ETH purchase removes supply from the float, and the market has started pricing that in.
Whether Bitmine pushes past the 5% threshold is the obvious next thing to watch. The company hasn't signaled a ceiling, and the disclosure language around the position has stayed consistent. For now, the only thing confirmed is that the accumulation continues.
