Bitmine Stakes $508M ETH Hitting 10.5% of Staked Supply

What the Numbers Show

Total staked ETH on Ethereum sits at roughly 38.9 million tokens, which represents about 32.2% of the 120.7 million ETH in circulation. Bitmine’s 4 million staked ETH makes it the single largest corporate staker on the network, according to Arkham’s entity dashboard.

In April 2026, Bitmine stakes ETH, holding 5.078 million tokens, with combined crypto and cash holdings of $13.3 billion. The company had already staked between 70% and 82% of its ETH in prior weeks.

At full staking capacity, Lee projects annual staking rewards of $363 million. The current network staking yield ranges between 2.8% and 3% APR, and Bitmine claims to outperform that average through its own infrastructure.

How Bitmine Staked ETH Through MAVAN

As Bitmine stakes ETH strategies scale, concerns around validator concentration are becoming harder to ignore. A single entity controlling a meaningful share of staked ETH introduces questions around decentralization, governance influence, and systemic risk. Bitmine conducts the majority of its staking through MAVAN, its proprietary institutional staking platform. MAVAN stands for Made in America Validator Network. It launched in March 2026.

The platform performs native staking, so Bitmine controls its validators directly. This differs from liquid staking protocols like Lido, where users receive derivative tokens in exchange. Bitmine also routes some of its ETH through Coinbase Prime for batch staking.

“MAVAN represents a critical step in our vision to build one of the leading staking and on-chain infrastructure platforms globally,” Lee said during the March launch announcement.

Bitmine’s Accumulation Timeline

The company’s pivot from Bitcoin mining to Ethereum treasury strategy began in mid-2025. Since then, its accumulation has been rapid and consistent.

In August 2025, Bitmine held approximately 1.52 million ETH, worth about $6.6 billion at the time. By January 2026, the company had staked more than 1.5 million ETH. That volume caused a visible backlog in Ethereum’s staking entry queue, as CoinDesk reported at the time.

When MAVAN launched in March, total staked ETH reached 3.14 million tokens, valued at $6.8 billion. By April, total holdings crossed 5 million ETH, representing about 4% of circulating supply. And now, on May 1, Bitmine staked ETH worth $508.4 million in a single move.

Centralization Concerns Around Staked ETH

One entity controlling 10.5% of all staked ETH raises questions about Ethereum’s decentralization. In proof-of-stake, network security depends on validator diversity. Concentrated staking can, in theory, influence finality or extract excess MEV.

Bitmine’s use of MAVAN and Coinbase Prime distributes its validators across multiple operators. That mitigates some single-point-of-failure risk. Still, it represents the largest corporate staking position on the Ethereum Beacon Chain.

Some Ethereum community members have flagged this concern before. When Bitmine’s January staking surge caused a queue backlog, analysts questioned whether one company should hold so much influence over the validator set. Lido, the largest liquid staking protocol, currently controls about 28% of staked ETH but spreads that across dozens of independent node operators.

Bitmine’s approach is different because it directly runs or delegates validators through MAVAN. That gives the company more direct control over its staking infrastructure than a liquid staking protocol would.

Market Reaction and Community Sentiment

On X, reaction to the Arkham report was mostly positive. Traders and institutional accounts highlighted the reduced liquid ETH supply and the yield generation potential. Arkham’s tweet itself was widely shared, with users calling the move “bullish” and pointing to estimated annual rewards near $284 million.

Retail sentiment on forums like r/CryptoCurrency and r/ethstaker was more mixed. While some praised institutional demand for ETH, others raised centralization and governance concerns.

“Bitmine has staked more ETH than any other entity in the world,” Lee said in an April press release. “At scale, the projected ETH staking reward is $363 million annually.”

What Comes Next for Bitmine

Bitmine stakes ETH stated that the goal remains of acquiring 5% of total ETH supply, a target it calls “Alchemy of 5%.” At 5.078 million tokens reported in April, the company already holds roughly 4.2% of circulating supply. The 5% target is within reach if accumulation continues.

Key questions remain unanswered, though. Bitmine has not disclosed its full exit or liquidity strategy. The company also has not confirmed whether it plans to migrate entirely from Coinbase Prime to MAVAN. The exact number and geographic distribution of its validators are not public.

For now, Bitmine’s staking dominance continues to grow. Whether that signals healthy institutional adoption or a concentration risk for Ethereum depends on who you ask.
