BitMine Immersion added another 15,112 Ether on October 5, 2026, a purchase worth roughly $41 million at current prices. The buy lifts the firm's total holdings to 6,016,414 ETH and puts it about 99% of the way toward its stated goal of controlling 5% of the entire Ethereum supply. The figures were reported by WatcherGuru and confirmed in posts from CoinMarketCap and CoinGecko citing the same acquisition.
Ether traded at $2,710 as of October 5, 2026, up 0.4% over 24 hours and 0.8% on the week. Against that flat backdrop, a single treasury buyer edging toward a twentieth of the circulating supply is the more consequential story than the price tape.
The accumulation math
BitMine, chaired by Fundstrat co-founder Tom Lee, has built its position through steady open-market buying rather than a single large block. The latest 15,112 ETH tranche is small relative to the 6 million-plus it already holds, which is the point: the firm is now close enough to its 5% ceiling that each incremental purchase moves the headline percentage only marginally.
Holding 5% of a major proof-of-stake network is a different proposition than holding 5% of Bitcoin. Ether is not just an asset to warehouse. Staked ETH earns a protocol yield, and a position this size gives the holder a meaningful voice in validation if any portion is staked directly. The company has not, in this announcement, broken out how much of the 6,016,414 ETH is staked versus held liquid, so the governance and yield implications remain an open question rather than a confirmed strategy.
A corporate treasury model built on one token
BitMine's approach echoes the Bitcoin treasury playbook that Strategy popularized, but concentrated on Ethereum instead. The same week BitMine crossed toward its 5% marker, Strategy reported a $21 billion fair-value gain on its Bitcoin holdings and lifted its stack to a record 848,000 BTC. Two public companies, two different base assets, one shared thesis: use the balance sheet as a vehicle for a single crypto asset and let the market price the equity as a proxy.
The concentration cuts both ways. A treasury this exposed to one token rises and falls with it. At $2,710, BitMine's 6,016,414 ETH is worth roughly $16.3 billion on paper; a sharp drawdown in Ether would hit the firm's mark-to-market value just as hard as the accumulation has lifted it. Investors buying the equity are, in effect, buying leveraged ETH exposure with a corporate wrapper around it.
Supply pressure and the demand question
Large standing bids like BitMine's remove float from the open market, which can tighten supply when demand is steady. That matters now because demand signals elsewhere have softened. Spot ETF inflows for altcoins including ETH-adjacent products have cooled sharply in recent weeks, a sign that the retail and fund bid is thinner than it was earlier in the cycle. A persistent corporate buyer partially offsets that, but it also concentrates the holder base, which can amplify volatility if that buyer ever becomes a seller.
For anyone holding ETH to spend rather than to speculate, the direct takeaway is limited. A treasury crossing a supply threshold does not change how an Ethereum-linked card settles a transaction or how staking yield accrues on a self-custodied balance. It is a signal about who owns the asset, not about how it is used at the point of sale.
The marker that is almost reached
The 5% target is a round, symbolic number more than a functional one. Nothing mechanically changes at 5% that was not true at 4.9%. What the near-miss does is mark how far a single accumulation vehicle has traveled in a short window, and it sets up the obvious next question: once the ceiling is hit, does BitMine stop buying, raise the target, or begin deploying the position into staking and governance. The firm has not said.
Overview
BitMine Immersion bought 15,112 ETH worth about $41 million on October 5, 2026, raising its total to 6,016,414 ETH, roughly 99% of its goal to hold 5% of all Ethereum supply. Ether traded at $2,710 at the time, little changed on the day. The purchase extends a Bitcoin-treasury-style playbook onto Ethereum, concentrating a large share of supply in one corporate balance sheet. That tightens available float while softer ETF demand cools elsewhere, and it leaves open how much of the stack is staked and what happens once the 5% marker is reached.
