Ethereum treasury firm BitMine Immersion Technologies has started staking a portion of its Ether holdings, marking a major operational shift as it looks to generate yield from one of the largest ETH reserves held by a single company.
On Sunday, onchain data showed several wallets linked to Bitmine transferring large amounts of Ether into a contract labeled “BatchDeposit,” a structure commonly used to prepare funds for validator activation under Ethereum’s proof-of-stake system.
The combined transfers amounted to 74,880 ETH, valued at close to $219 million at prevailing prices, and closely matched patterns typically associated with institutional staking operations rather than retail activity.
“The largest Ethereum treasury company Bitmine (BMNR) has finally started attempting to stake its held ETH to earn interest income,” onchain analyst EmberCN wrote in a post on X.
“This is their first time staking, and they now hold 4.066 million ETH, with an approximate APY of 3.12%. If all of it were staked, they could earn about 126,800 ETH in interest over a year, which at the current price of $2,927 would be worth $371 million,” EmberCN added.
The move comes shortly after Bitmine confirmed that its total Ether treasury had exceeded 4 million tokens for the first time, reinforcing its status as the largest known corporate holder of ETH.
Earlier this week, the company disclosed that its balance now stands at more than 4.06 million ETH following a $40 million purchase that added to its already sizable holdings.
Over the past seven days alone, Bitmine accumulated nearly 100,000 ETH, paying an average price of $2,991 per token during that buying spree.
Staking plans laid out well in advance
While the latest deposits mark Bitmine’s first visible staking activity, the company has previously outlined longer-term plans to fully integrate staking into its treasury strategy.
In November, Bitmine said it intends to begin broader Ether staking in the first quarter of 2026 through a proprietary infrastructure initiative known as the Made-in America Validator Network, or MAVAN.
At the time, the firm explained that it had selected three institutional staking providers to participate in a pilot program designed to test performance, security standards and operational reliability.
Only a small portion of its ETH holdings was expected to be used during the trial phase, with scaling decisions dependent on results from those initial deployments.
The latest transfers suggest Bitmine may be accelerating its learning curve, even if full-scale staking across its entire treasury remains a longer-term objective.
Institutional interest could reshape Ethereum’s onchain economy
Bitmine’s activity is unfolding against a backdrop of growing institutional focus on Ethereum’s role as financial infrastructure rather than a purely speculative asset.
Joseph Chalom, co-CEO of Sharplink Gaming, the second-largest public Ethereum treasury holder, has argued that Ethereum’s total value locked could expand dramatically as institutions increase their onchain exposure.
According to Chalom, Ethereum’s TVL could grow as much as tenfold in 2026 if stablecoin usage, tokenization and institutional settlement continue to gain momentum.
He pointed to stablecoins as a particularly powerful driver, noting forecasts that the sector could reach a market size of $500 billion by the end of next year.
With more than half of global stablecoin activity already taking place on Ethereum, sustained issuance and transaction volume could significantly lift staking demand, network fees and overall economic activity.
For firms like Bitmine, the combination of large-scale ETH holdings and predictable staking yield may increasingly resemble a long-term balance-sheet strategy rather than a tactical Crypto bet.
