Bitmine's Ethereum stack just got a lot bigger. The mining firm now holds 5.54 million ETH — equivalent to 4.59% of all Ether ever issued — after scooping up 127,000 coins over the past period. The buying came during a stretch of weak market prices, suggesting the company saw the dip as an opportunity rather than a reason to sell.
How the treasury grew
Bitmine didn't announce the purchase with a press release or a tweet. The data surfaced on-chain, where wallet tracking shows the company's main treasury address swelled by roughly 127,000 ETH in recent weeks. That brings its total known balance to 5.54 million tokens. The acquisition was executed through a series of smaller transactions — nothing flashy, just steady accumulation. At current prices, the stash is worth well over $10 billion, though Bitmine hasn't said whether it plans to hold or deploy the coins.
Why weak prices matter
The timing is telling. Ether has traded below $1,900 for most of May and early June, down about 30% from its 2026 high of $2,750. For a miner like Bitmine, that's a double-edged sword. Lower prices squeeze operating margins, but they also let the company buy cheap. The 127,000 ETH added to the treasury likely cost significantly less than what Bitmine would have paid three months ago. It's the kind of move that looks like a bet on a rebound — or at least a hedge against having to sell into a weak market later.
What 4.59% control means
Controlling nearly one out of every twenty Ethereum coins gives Bitmine real influence. The company could swing staking rewards, governance votes on Ethereum Improvement Proposals where token-weighted voting matters, and overall market liquidity. A single entity holding that much supply also raises concentration risk — if Bitmine ever decided to offload a big chunk, the market would feel it. So far, though, the firm has been a net accumulator, not a seller. The last big disposal was back in early 2025, when it sold about 50,000 ETH to fund expansion into AI computing.
What comes next
Bitmine hasn't signaled any change in strategy. The company's next quarterly earnings call is expected in mid-July, and investors will likely press for details on the Ethereum position. Meanwhile, the rest of the market is watching the wallet. If Bitmine keeps buying during the next dip, it could set a floor under Ether. If it stops, traders might wonder why. Either way, the mining giant's balance sheet is now a major piece of the Ethereum supply picture.
