Bitmine Immersion Technologies has bought enough ether to put it within striking distance of a target almost no single entity has set for a major asset: owning 5% of the entire circulating supply. As of mid-June 2026, the company holds 5.54 million ETH, equal to about 4.59% of the roughly 120.68 million ETH in circulation. That leaves it around 92% of the way to its self-named "Alchemy of 5%" goal, according to figures the company disclosed and reporting from The Block. Cointelegraph put the progress at 91% in a June 20 update.
The position is large by any measure. At ETH's price of about $1,725 as of June 20, 2026, per CoinMarketCap, 5.54 million ether is worth roughly $9.6 billion. Reaching a clean 5% would require roughly 6.03 million ETH, so Bitmine still needs close to half a million more coins to finish the job.
The accumulation has accelerated, not slowed
Bitmine has been buying since mid-2025, but the recent pace stands out. The company logged its single largest weekly ETH acquisition of 2026 in June, timed to a stretch when ether traded near its low for the year. One purchase of 126,971 ETH came in at an average price near $1,630, the kind of entry that only works at scale and with cheap capital behind it.
That capital is the engine. Bitmine closed a $274 million preferred stock offering on June 10 to keep funding purchases. This is the same playbook bitcoin treasury companies have run for years: issue equity or preferred shares while the stock trades at a premium to the crypto it holds, then convert that paper into more coins. The model works as long as investors keep paying up for exposure through the stock. It strains when the premium compresses or the underlying asset falls faster than the company can raise.
A single holder near one in twenty ether
Concentration is the part worth sitting with. If Bitmine reaches 5%, one publicly traded company would control one of every twenty ether that exists. That has real implications for how the asset trades. A holder that size becomes a price-setting force on the way in, and a source of overhang on the way out. Markets tend to watch large single wallets closely, and a treasury this concentrated turns every financing decision the company makes into an ETH market event.
There is also the staking question. Ethereum treasuries usually do not let coins sit idle; they put them to work for staking yield, which compounds the holding over time and deepens the company's dependence on the network performing as designed. The flip side is that a large staked position is slower to exit, since unstaking and withdrawal queues add friction that a spot seller does not face.
The treasury trade is crowding into one asset
Bitmine is not alone in turning a public company into a crypto vault, but it is the most aggressive on ether specifically. The broader pattern now spans chains: five public Solana treasury firms together hold more than $1 billion in SOL, and bitcoin treasury vehicles have authorized financing in the tens of billions. The common thread is leverage on a single token, with the equity market acting as the funding layer.
For ether holders, the upside case is straightforward. A buyer absorbing supply at this rate removes coins from circulation and adds a steady bid. The downside case is just as clear. The same buyer, if forced to raise cash or wind down, becomes the largest potential seller in the market. Sentiment is already cautious: the Fear and Greed Index sat at 21, or "Fear," on June 20, 2026, even as ETH rose 1.6% on the day.
Overview
Bitmine holds 5.54 million ETH, about 4.59% of the circulating supply, and is roughly 92% of the way to its stated 5% target. The position is worth close to $9.6 billion and was built largely by buying into June's price weakness, funded by a $274 million preferred stock raise. The strategy concentrates a meaningful slice of Ethereum in one public company's hands, which cuts both ways: a durable bid while the model holds, and a single point of failure if it does not. The next data point to watch is whether Bitmine closes the final half-million ETH gap or, as some recent reporting suggests, deliberately slows its approach to the line.
