BitMine Nears 5% of ETH Supply: Risk or Opportunity?

Original author: Xiao Bing

As of Aug. 24, BitMine Immersion Technologies (NYSE: BMNR) held 5,847,611 ETH, worth approximately $14.3 billion, representing 4.84% of Ethereum's total supply. The company is about 187,000 ETH short of its self-imposed 5% target (approximately 6.04 million ETH). At the recent weekly purchase pace of 32,447 ETH, this target could be reached in about six weeks.

BitMine's chairman is Tom Lee, one of Wall Street's most prominent crypto bulls and co-founder of Fundstrat Global Advisors. He calls this target the "Alchemy of 5%." Since launching its Ethereum treasury strategy on June 30, 2025, BitMine has bought ETH every week without interruption.

A publicly traded company is about to become one of the largest single holders of tokens on the world's second-largest blockchain network, and also its largest staker.

From Mining Rig Cooling to ETH Whale

BitMine was originally a small company making immersion cooling mining equipment. In early 2025, after Tom Lee took over, the company completed a radical strategic transformation: from selling mining equipment to hoarding Ethereum.

The growth has been rapid.

In August 2025, holdings reached 1% of ETH supply, and 2% in September. That September, the company raised $365 million through a secondary offering at $70 per share. In March 2026, holdings surpassed 4.66 million ETH, and in May, 5.2 million. In June 2026, the company raised another $274 million by issuing 9.5% preferred stock (ticker BMNP) at $80 per share. Investors included ARK Invest (Cathie Wood), Founders Fund, Pantera Capital, Kraken, and Galaxy Digital.

On June 26, 2026, BitMine was added to the Russell 1000 large-cap index.

Besides ETH, BitMine also holds 210 bitcoins, a $180 million equity stake in MrBeast's Beast Industries, an $89 million stake in Eightco Holdings (NASDAQ: ORBS), and about $308 million in cash and marketable securities. The company classifies Beast and Eightco as "moonshots," with total assets of approximately $14.9 billion.

Largest Staker

BitMine doesn't just hoard coins. It has staked a large portion of its ETH on the Ethereum network.

As of Aug. 23, BitMine had staked 5,067,309 ETH, about 87% of its total holdings, worth approximately $12.4 billion. The company built its own staking platform called MAVAN, initially for its own assets, with plans to open it to institutional investors and custodians. Based on BitMine's disclosed 2.61% seven-day annualized yield, staking generates annualized income of about $287 million.

Putting this number in the context of the entire Ethereum network: currently, about 42 million ETH are staked network-wide, representing 34% of total supply. BitMine's 5.07 million staked ETH accounts for about 12% of the network's total staked amount. Lido is currently the largest staking service provider, holding about 8.83 million staked ETH, or 20.9% of the staking market. BitMine alone has reached 57% of Lido's staking scale.

Tom Lee proudly stated that BitMine stakes more ETH than any other entity in the world.

What Does 5% Mean?

Owning 5% of ETH does not give BitMine any direct control over the Ethereum network. Ethereum's protocol upgrades are decided through the EIP process and rough consensus among core developers, not influenced by token holdings. Owning ETH does not equate to voting rights. Ethereum also has no on-chain governance mechanism.

But a 12% share of network staking is not a number to ignore.

Ethereum's PoS consensus relies on a broad distribution of validators to maintain network security and censorship resistance. The community already has significant controversy over Lido's 20% staking share, arguing that excessive concentration in a single entity could pose systemic risks. BitMine's 12% staking share, combined with the fact that it is a publicly traded company subject to U.S. securities laws, means its staking activities could be influenced by the SEC, CFTC, or other regulators.

Consider an extreme scenario: if the U.S. government imposes sanctions or compliance requirements on Ethereum (similar to OFAC's sanctions on Tornado Cash), BitMine, as a public company, would have to comply. Its 5.07 million staked ETH represent 12% of the network's consensus weight. A company forced to change its validation behavior due to regulatory pressure would affect not just itself, but the neutrality of the entire network.

This is not a theoretical concern. In August 2026, Lido publicly disagreed with Ethereum core developers over EIP-8363, a proposal affecting staking yields. When a staking participant becomes large enough, it ceases to be a passive stakeholder and becomes a power node in protocol politics.

Two Sides of the Investment Narrative

The investment narrative for BitMine can be understood from two completely opposite directions.

The bullish logic chain is: ETH's current price is far below BitMine's average purchase price. If the Ethereum ecosystem's fundamentals improve (accelerated RWA tokenization, increased L2 activity, greater inflows into ETH ETFs), and ETH's price rebounds above $4,000, BitMine's paper losses would quickly turn into profits. Meanwhile, the $287 million annualized staking income provides a cash flow floor. After being added to the Russell 1000, passive index fund buying will continue to support the stock price, and the current NAV discount provides a margin of safety.

The bearish logic chain is equally clear: ETH's relative weakness is not short-term volatility but reflects the market's repricing of Ethereum's role in the AI era. BitMine's entire investment thesis rests on the single judgment that "ETH should be more expensive." If ETH oscillates between $2,000 and $3,000 for a long time, the $9.1 billion unrealized loss will not disappear, the 9.5% preferred stock dividend will continue to be paid, and the staking yield (2.6%) is far from enough to cover financing costs.

The company has no substantial revenue source other than ETH. This is an all-in leveraged bet on a single asset, not an operating business with diversified revenue streams.

In a statement on Aug. 24, Tom Lee noted that ETH rose 30% in the past week, the largest weekly gain since May 2025, and that historically, weekly gains of similar magnitude often mark the beginning of larger rallies.

Only 187,000 ETH, worth about $460 million at current prices, separates BitMine from the 5% mark. For a company that buys every week, this number could be crossed before year-end. At that point, the crypto industry will face an unprecedented situation: a NYSE-listed company holding over 5% of the token supply of the world's second-largest blockchain, staking 12% of the network's consensus weight, and still potentially carrying billions of dollars in unrealized losses on its books.

Whether the "Alchemy of 5%" can turn stone into gold depends entirely on the direction of ETH's price.
