Bitmine, the world’s largest public Ethereum treasury company, has taken a major step in monetizing its holdings by initiating staking on the Ethereum proof-of-stake network.
On December 27, 2025, on-chain data showed wallets linked to the firm depositing roughly 74,880 ETH, valued at about $219 million, into the Ethereum deposit contract.
The move comes as Bitmine’s total Ethereum holdings surpass 4 million ETH, worth more than $12 billion, positioning the company as one of the most influential participants in the Ethereum ecosystem.
First Step Toward Active Yield Generation
The initial staking transaction marks Bitmine’s first shift away from a purely passive treasury strategy. Until now, the firm had focused on accumulating and holding ETH. By staking a portion of its reserves, Bitmine has begun generating on-chain yield from assets that were previously idle.
At current network conditions, Ethereum staking yields are estimated at around 3.12% annually. If Bitmine were to stake its entire treasury of approximately 4.06 million ETH, annual income could reach an estimated $371 million, based on prevailing prices and yield levels.
Offsetting Volatility With Protocol Income
Bitmine’s strategy also has balance-sheet implications. The company’s average acquisition cost for its ETH holdings is estimated near $2,991 per token, meaning staking income could help offset unrealized losses during periods of market volatility.
Rather than relying solely on price appreciation, staking allows Bitmine to extract recurring cash-flow-like returns directly from the Ethereum network. This introduces a new layer of financial resilience to its treasury model.
Preparing for a U.S.-Based Validator Network
The December deposit is described as a pilot program ahead of a larger operational rollout. Bitmine plans to launch its in-house Made-in-America Validator Network (MAVAN) in early 2026, which would allow the company to operate its own Ethereum validators at scale.
Running proprietary validators would give Bitmine greater control over infrastructure, security standards, and operational costs, while anchoring its staking activity within the United States.
Long-Term Accumulation Strategy
Led by Chairman Tom Lee, Bitmine has publicly stated an ambition to eventually control 5% of the total ETH supply. The transition from passive holding to active staking suggests that the firm is now focused not only on accumulation, but also on optimizing the economic output of its growing reserves.
A New Phase for Corporate ETH Treasuries
Bitmine’s move highlights an evolution in how large institutions approach Ethereum. With Ethereum now fully proof-of-stake, holding ETH increasingly resembles owning a yield-bearing digital asset rather than a non-productive reserve.
By beginning to stake at scale, Bitmine is setting a precedent for how corporate Ethereum treasuries may operate going forward, blending long-term conviction with on-chain income generation.
