Bitmine’s Ethereum war chest is now big enough to worry about market concentration. The firm disclosed this week that its treasury holds 5.54 million ETH — about 4.6% of the total supply and closing in on that 5% target it first flagged last year. Roughly 127,000 ETH landed in Bitmine’s wallets over the past seven days, keeping the accumulation pace aggressive.
Five percent in sight
That 5% supply threshold has been a self-imposed benchmark for Bitmine, and at today’s numbers they’re less than half a percentage point away. With the latest weekly injection, the math is simple: another big buy or a couple of weeks at the current rate and they’ll cross it. The firm has never said publicly what happens when they hit 5%, but the market is watching closely — a single entity holding one-twentieth of all Ether carries obvious governance and liquidity implications.
Staked and locked
Bitmine isn’t just sitting on that ETH. More than 4.7 million of those coins are actively staked through the company’s validator infrastructure. That means roughly 85% of the treasury is earning yield and also removing coins from circulating supply. The staked portion alone represents about 3.9% of all staked Ether, giving Bitmine outsized influence over consensus proposals and network upgrades.
Where the new ETH came from
The 127,000 ETH added this week weren’t mined or earned through fees — they were bought on the open market, according to the firm’s disclosure. Bitmine has been steadily accumulating since late 2025, with purchases ramping up after the Dencun upgrade stabilized gas fees. No single exchange or OTC desk handled the entire buy, but the recurring volume has been enough to nudge spot prices on days Bitmine’s wallets go active.
With the 5% line now visible on the dashboard, the next question is whether Bitmine slows down or accelerates. The firm hasn’t given any guidance on post-target strategy.
