Grayscale Investments and Bitmine have collectively staked nearly $500 million in Ethereum over the past 24 hours, according to Arkham Intelligence on-chain data.

Grayscale deposited an additional 102,400 Ether, valued at approximately $237 million, through 32 transactions from its Ethereum Trust wallet to Coinbase Prime. The firm activated staking for its Ethereum products in late October 2025 and has since accumulated nearly $38 million in net staking rewards.

As of April 24, combined assets under management for Grayscale's Ethereum ETFs have reached $4 billion.

Meanwhile, Bitmine Immersion Technologies has emerged as the largest corporate Ethereum staker. The firm disclosed this week that its staked ETH now totals 3.3 million units, representing 67% of its holdings. Further staking on Friday brought Bitmine's total staked ETH to 3.7 million, or approximately 74% of its total holdings.

Approximately 39 million ETH is currently locked in staking contracts across the network, with nearly a third of all existing Ethereum voluntarily removed from trading pools to earn yield.
