Bitmine buys 71,524 ETH in a week, lifting holdings to about 4.87M

Bitmine Immersion Technologies disclosed a 71,524 ETH weekly purchase that it described as its fastest accumulation pace since December 2025. The buy pushed Bitmine’s Ether holdings to about 4.87 million ETH, which the company said equals roughly 4.04% of total ETH supply.

Key Takeaways

• A 71,524 ETH weekly purchase lifted Bitmine’s Ether holdings to about 4.87 million ETH.
• The company pegged its position at roughly 4.04% of total ETH supply using about 120.7 million ETH outstanding, and it reiterated a target of acquiring up to 5%.
• About 3.33 million ETH is staked through Bitmine’s in-house MAVAN platform, with projected annual rewards of roughly $310 million based on recent yields.
• Bitmine reported holding 198 BTC and about $719 million in cash, and it debuted on the NYSE on April 9 after uplisting from NYSE American.

Bitmine’s Weekly ETH Buy Pushes Holdings to ~4.87M

Bitmine Immersion Technologies said it purchased 71,524 ETH over the past week, bringing total holdings to about 4.87 million ETH. The company described the pace as its fastest weekly Ether accumulation since December 2025.

On Bitmine’s own math, that balance equates to roughly 4.04% of total ETH supply, using about 120.7 million ETH outstanding as the denominator. For traders, the headline is not just the size of the buy. It is the emergence of a single corporate treasury large enough to become a recurring driver of positioning whenever it signals continued accumulation.

CoinGecko data ranks Bitmine as the largest Ethereum treasury company by a wide margin. The same dataset lists SharpLink at about 868,699 ETH and The Ether Machine at 496,712 ETH.

From 4.04% of Supply to a 5% Target: The Concentration Angle

Bitmine reiterated a target of acquiring up to 5% of global ETH supply. The disclosure did not include a timeline or a funding plan for reaching that level.

The market-structure implication is straightforward. At 4.04% of supply, incremental buys and any perception of a “programmatic” bid can start to matter for liquidity expectations, especially if the company keeps adding at a pace comparable to the latest 71,524 ETH week. Even without a published schedule, the stated 5% target creates a reference point that can anchor narratives around float concentration and marginal supply.

Bitmine also disclosed a balance sheet that includes 198 BTC and about $719 million in cash. Combined with its April 9 debut on the New York Stock Exchange following an uplisting from NYSE American, the capital base and listing venue provide tangible context for how the strategy could be scaled, even if the next steps are still undefined.

3.33M ETH Staked on MAVAN and the $310M Rewards Projection

Bitmine said about 3.33 million ETH is currently staked through MAVAN, its in-house platform. It projected annual rewards of roughly $310 million based on “recent yields.”

That framing matters because it positions the strategy as both accumulation and yield capture. If a large portion of the treasury is staked, it can reinforce incentives to keep holdings locked rather than liquid, tightening the effective float. The caveat is that the $310 million figure is assumption-heavy. The disclosure did not specify the yield inputs, whether the estimate is net of fees and operating costs, or how rewards might change with network conditions.

Signals Traders Can Track After the Disclosure

The next set of disclosures will determine whether this remains a headline-grabbing snapshot or turns into a repeatable flow. The missing detail traders will want first is execution transparency: average purchase price, total cost, and where the 71,524 ETH was sourced.

The real catalyst would be a clearer path to the “up to 5%” target, including any timeline, funding plan, or capital actions following the NYSE uplisting. On the staking side, changes in the amount of ETH routed through MAVAN and any revised yield assumptions behind the projected ~$310 million annual rewards will signal whether Bitmine is leaning further into a lock-up posture.

Finally, the simplest tell is whether Bitmine reports additional weekly ETH accumulation at a pace comparable to the latest purchase.

When a Single Treasury Nears 5% of ETH Supply

I treat this as a liquidity story first and a narrative story second. A disclosed 4.04% supply share is big enough that the market starts to price the possibility of persistent corporate demand, and the threshold that matters is whether Bitmine can keep printing weeks like 71,524 ETH without telegraphing stress in funding or execution.

The real test is whether the staking footprint stays large while the treasury grows. If 3.33 million ETH remains staked and the company continues buying toward its stated 5% target, the setup starts to look structural rather than narrative-driven because it tightens effective float while adding a visible, repeatable bid that traders can front-run or fade depending on follow-through.
