Bitmine now holds 4.3% of all Ethereum in circulation. The mining firm’s staking operations are pulling in $319 million a year in rewards. That’s a bigger concentration than most people realize.
The numbers inside Bitmine’s stash
That 4.3% slice of the ETH supply is worth billions at current prices. And the $319 million in annual staking revenue means Bitmine is one of the single largest validators on the network. The firm isn’t just sitting on the coins — it’s actively earning yield from them.
A single entity controlling that much ETH creates a lopsided validator set. The network’s security model depends on broad distribution. When one player holds nearly 5% of the supply, the math on finality and censorship resistance shifts. It’s not a crisis yet, but it’s a number the community keeps an eye on.
How Bitmine got here
Bitmine has been a major Ethereum miner for years. With the transition to proof-of-stake, the firm shifted its hardware into staking pools and direct validators. The revenue figure suggests they’ve been compounding rewards aggressively. No other single entity has publicly disclosed a comparable stake.
What comes next
Bitmine hasn’t said whether it plans to grow its share further. The Ethereum ecosystem is watching. If the share climbs past 5%, regulators might start asking questions. For now, the firm keeps stacking ETH — and collecting that $319 million annual check.
