Bitmine Increases ETH Holdings to 5.7M After Joining Russell 1000

Bitmine Immersion Technologies said it added more than 27,000 Ether to its treasury last week after completing a $43 million purchase. The update comes as the company prepares for greater visibility with its inclusion in the Russell 1000, an index that many funds use as a benchmark for passive investing.

In a disclosure shared on Monday via PR Newswire, Bitmine said its Ether holdings reached just over 5.7 million ETH. The company reported buying the tokens at an average price of $1,569 per Ether and said it now holds about 4.7% of Ethereum’s 120.7 million token supply—moving it closer to its stated objective of owning 5% of the asset.

Key takeaways

• Bitmine reported a $43 million Ether purchase that increased holdings to just over 5.7 million ETH at an average $1,569 per token.
• The firm said its stake is now roughly 4.7% of Ethereum’s circulating supply, edging toward a 5% target.
• Bitmine’s Russell 1000 inclusion is expected to bring additional institutional demand through funds that track the index.
• Despite broader Ethereum developments, Bitmine’s chairman described the prior week as difficult for crypto investors after Ether fell about 8%.
• Other crypto-linked firms were also added to the Russell 3000 Index recently, expanding how traditional investors encounter crypto treasury businesses.

A growing Ether treasury amid a volatile week

Bitmine’s announcement frames the latest acquisition as part of a continued push to build a larger corporate Ether position. After its recent buy, the company said it holds slightly above 5.7 million Ether and has reduced the gap to its 5% supply goal.

The filing also highlights how market price swings can complicate treasury strategies even when the broader Ethereum ecosystem is active. Bitmine chairman Tom Lee characterized the preceding week as challenging for crypto investors, saying Ether fell by 8%. In his remarks, he noted Ethereum-related positives—including the creation of Ethlabs—and pointed to a softer tone from the Bank of England regarding stablecoins.

Even with those developments, Lee said the selloff played out in ways that can influence investor behavior. He later attributed some of the pullback to what he described as “window dressing,” where investors reduce exposure to assets that have declined over recent months.

Why Russell 1000 inclusion could change Bitmine’s investor base

Beyond the treasury update, the more market-facing development is Bitmine’s addition to the Russell 1000, which tracks the largest 1,000 US companies. Bitmine said this step may increase investor demand for its shares because many mutual funds, ETFs, and pension funds follow Russell indices and must buy constituents once they are added.

Lee previously discussed this mechanism when Bitmine was first under consideration for the Russell index in May. He said passive index funds can account for up to 25% of the market capitalization of stocks included in the index.

In Monday’s comments, Lee said Russell 1000 membership is expected to add “hundreds and possibly thousands” of additional institutional investors as equity owners of Bitmine. For a company whose business model is closely tied to holding and managing Ether exposure, a shift in the shareholder base can matter: institutional ownership patterns can influence liquidity, trading volume, and the range of investors willing to hold crypto-treasury equities over the long run.

Stock movement follows Ether, despite new corporate catalysts

Bitmine’s share performance on Monday reflected both the company’s corporate update and the broader pressure on Ether. The stock rose 1.7% to close at $13.80, according to the article, but it has fallen roughly 9% over the past week in tandem with Ether’s decline.

That pattern underscores an important tension for investors watching crypto treasury businesses: even when the company executes meaningful purchases or secures index inclusion, the underlying price of Ether can still dominate near-term equity performance. In other words, Bitmine’s catalysts may improve access to new capital sources, but the valuation of its holdings remains directly linked to market conditions for ETH.

Broader index adoption for crypto-related firms

The Russell inclusion story is not unique to Bitmine. The article noted that rival crypto treasury firms Sharplink and Forward Industries—along with Gemini and Galaxy Digital—were also added to the Russell 3000 Index on Friday. The Russell 3000 tracks the largest 3,000 US companies, which can create additional pathways for traditional market participants to build exposure to crypto-linked public equities.

For investors, this trend signals a gradual normalization of crypto-related businesses inside mainstream index ecosystems. However, it also raises a watchpoint: as more crypto treasury firms enter large-cap indices, their stock demand may become more mechanically tied to index-tracking flows, potentially increasing short-term trading activity around reconstitution dates.

At the same time, it does not remove the central risk for equity holders—Ether’s market volatility. Bitmine’s chairman’s remarks about window dressing and short-term reductions in exposure illustrate how quickly sentiment can shift even when broader Ethereum developments continue.

Investors should watch whether Bitmine’s Russell 1000 entry translates into sustained institutional ownership or whether near-term trading remains dominated by ETH price movements. The next key question is how the company continues to balance incremental Ether acquisitions with the equity volatility created by shifting crypto market sentiment.
