Bitmine added 159,728 ETH to its staking position on Oct. 21, a transaction worth roughly $390.6 million at the time. The move pushes the share of the company's treasury that is staked to 86.5%, according to onchain analysts who flagged the transfer.
The company, associated with Tom Lee, now has 5.23 million ETH staked in total, valued near $12.78 billion. That's a substantial concentration of its balance sheet in a single yield-bearing position.
What the 159,728 ETH transfer actually did
The staking transaction didn't come out of nowhere. It was picked up by onchain analysts tracking large ETH movements, and the number is specific enough to be verifiable: 159,728 ETH. At current prices, that's about $390.6 million. The transfer moved the company's staked ratio from whatever it was before to 86.5% — a figure that tells you most of Bitmine's treasury is now working rather than sitting idle.
Staking means locking up ETH to help secure the network in exchange for rewards. For a treasury of Bitmine's size, the difference between staked and unstaked ETH is the difference between earning yield and not. The company has clearly chosen the former.
The scale of Bitmine's ETH position
5.23 million ETH. That's the total staked position, and at current valuations it's worth near $12.78 billion. To put it plainly, Bitmine isn't a casual staker. The company's treasury strategy appears built around accumulating and staking ETH at a scale that few other corporate entities can match.
The 86.5% staked share is the number that matters most here. It means the vast majority of Bitmine's ETH holdings are locked in staking contracts, generating rewards, and not available for quick liquidation. That's a deliberate choice — and one that carries both upside and risk.
Who's behind the move
Bitmine is associated with Tom Lee, a name familiar to anyone who's followed crypto markets over the past few years. Lee has been a prominent voice on Ethereum and digital assets, and Bitmine's staking activity fits with a long-term conviction approach rather than a trading mindset. The company didn't issue a public statement alongside the transaction, but the onchain data is unambiguous.
The staking transfer was reported by analysts who track large wallet movements, not by Bitmine itself. That's worth noting because it means the information comes from blockchain data rather than a press release. The 159,728 ETH figure and the 86.5% staked share are both derived from that onchain analysis.
What the staked ratio signals
An 86.5% staked share is high. For a company holding billions in ETH, it suggests a treasury policy that prioritizes yield generation over liquidity. Staking rewards on 5.23 million ETH aren't trivial, but the trade-off is that the assets are locked. If Bitmine needed to move quickly — to cover expenses, seize an opportunity, or respond to a market event — most of its ETH wouldn't be immediately available.
The remaining 13.5% of the treasury that isn't staked gives the company some breathing room. But the direction is clear: Bitmine is betting on Ethereum's staking economy in a big way, and the Oct. 21 transaction is the latest step in that strategy.
The next data point to watch
Onchain analysts will keep tracking Bitmine's wallets for further staking moves. The question now is whether the company pushes its staked share even higher — toward 90% or beyond — or whether 86.5% represents a ceiling. There's no public guidance from Bitmine on that, and the company hasn't signaled its next move. For now, the numbers speak: 5.23 million ETH staked, $12.78 billion in value, and a treasury that's overwhelmingly committed to the staking contract. The next transfer will be visible onchain before it's visible anywhere else.
