BitMine boosts Ethereum treasury with $45m as holdings near $10b

BitMine has picked up another batch of Ether, extending a buying streak that has made it one of the most aggressive ETH accumulators in 2025.

Ethereum treasury firm BitMine Immersion has added another 10,320 ETH (ETH) to its growing stash. According to data from on-chain tracker Lookonchain, the purchase was worth about $44.6 million at the time of transfer, pushing the company’s total holdings to 2.07 million ETH valued at nearly $8.94 billion. 

Blockchain data from Arkham Intelligence shows the acquisition was carried out through three separate transfers from Galaxy Digital’s over-the-counter desk. The buy comes just days after the firm made one of the largest single-day ETH purchases ever recorded. That earlier move was valued at $358 million, extending its month-long accumulation trend of ETH.

With its latest addition, BitMine’s treasury now represents about 1.71% of total ETH supply, all built up in under two months. Despite this rapid pace, the company has met only 34.2% of its longer-term target, leaving significant room for expansion as it continues stockpiling.

BitMine’s accumulation is not happening in isolation. Across the sector, more firms are steadily adding Ether to their treasuries, pushing total institutional reserves higher and signaling that the appetite for ETH as a strategic asset continues to grow.

Ethereum treasury strategies march on

Ethereum treasuries have continued to expand in recent months, with new inflows showing that corporate and institutional buyers remain committed to stockpiling the asset. The growth builds on momentum from the summer, when ETH reserves began accelerating across dozens of entities.

Alongside BitMine, SharpLink Gaming has been active this month, adding to its Ethereum reserves as it continues to push toward completing its treasury target. The company now holds around 837,000 ETH valued at $3.63 billion, making it the second-largest corporate holder. Holding the third position is The Ether Machine, with more than 495,000 ETH now in its treasury, worth about $2.15 billion.

Performance among the top three treasuries has been strong over the past 30 days, as on-chain data shows. BitMine’s holdings surged 148% in value as its accumulation streak continued, while SharpLink gained 60% and Ether Machine climbed 43%.

Behind these headline figures is a broader build-up of Ethereum treasuries across dozens of entities. Since mid-July, more than 70 firms have accumulated reserves, taking total holdings to 4.91 million ETH valued at $21.29 billion. This is equal to just over 4% of the token’s supply, highlighting how quickly Ethereum has become a preferred asset for treasury accumulation.
