Key Takeaways
- • Grayscale and Bitmine collectively staked nearly $500 million in Ethereum over 24 hours (as of April 25, 2026), with Grayscale depositing 102,400 ETH ($237 million) and Bitmine staking 112,040 ETH ($259.6 million), according on-chain data from Arkham Intelligence and Lookonchain.
- • Bitmine is now the largest corporate Ethereum staker, holding 3.7 million ETH ($8.58 billion) with 74% of total holdings locked in staking contracts, up from 67% earlier in the week.
- • Approximately 39 million ETH (nearly one-third of total supply) is now locked in staking contracts, materially reducing liquid supply available for trading and creating structural support for Ethereum's price through reduced circulation.
- • Grayscale's Ethereum staking ETF products (ETHE and ETH Mini) achieved $4 billion in combined AUM as of April 24, 2026, with the firm ranking first among US exchange-traded product providers in Q1 2026 with $337 million in quarterly inflows and $38 million in accumulated net staking rewards since launch in October 2025.
- • The staking surge demonstrates institutional demand for Ethereum yield generation, with both legacy asset managers and specialized crypto firms competing to capture Ethereum's 3.5–4.2% staking yield while simultaneously reducing market liquidity.
Summary
Grayscale Investments and Bitmine Immersion Technologies executed coordinated large-scale Ethereum staking transactions totaling nearly $500 million within a single 24-hour period, marking a significant institutional commitment to locking up supply and capturing staking yield. Grayscale deposited 102,400 ETH (approximately $237 million) from its Ethereum Trust wallet to Coinbase Prime across 32 separate transactions, while Bitmine staked an additional 112,040 ETH worth $259.6 million on April 25, 2026, according to on-chain data providers Arkham Intelligence and Lookonchain.
Bitmine has emerged as the largest corporate holder and staker of Ethereum, with total staked holdings reaching 3.7 million ETH ($8.58 billion), representing 74% of its total Ethereum position. The firm's aggressive staking strategy reflects confidence in Ethereum's yield economics and long-term value proposition. Grayscale, meanwhile, has institutionalized Ethereum staking through its suite of US-listed spot ETFs—the Grayscale Ethereum Staking ETF (ETHE) and Grayscale Ethereum Staking Mini ETF—which together hold $4 billion in assets under management as of April 24, 2026. CEO Peter Mintzberg reported that Grayscale's Ethereum staking products ranked first among all US exchange-traded product providers in Q1 2026, generating $337 million in quarterly inflows and accumulating $38 million in net staking rewards since the products' launch in October 2025.
The cumulative impact of institutional staking is creating meaningful supply constraints. Approximately 39 million ETH—nearly one-third of the total circulating supply—is now locked in staking contracts across the Ethereum network, according to beaconcha.in data. Each additional amount staked removes liquid Ethereum from trading markets, reducing supply available for transactions and potentially exerting upward pressure on price. This supply tightening mechanism mirrors institutional strategies in other asset classes and reflects a structural shift toward locked-up, yield-bearing positions among sophisticated investors. The 3.5–4.2% staking yield available to Ethereum holders has become a meaningful consideration for portfolio managers evaluating risk-adjusted returns in alternative assets.
