Bitmine vs BlackRock: Who’s Accumulating More ETH Right Now?

Bitmine vs BlackRock, two of the biggest institutional names in crypto are quietly loading up on Ethereum — and the numbers are staggering.

The race to own $ETH at scale has begun. The question is who is winning it.

Bitmine Is Playing an Entirely Different Game

Bitmine Imersion Technologies (NASDAQ: BMNR) now holds 5.18 million $ETH — worth over $12 billion at current prices.

That is 4.29% of Ethereum’s total circulating supply. The firm has staked 4.36 million $ETH, generating an estimated $352 million in annual staking rewards.

The accumulation pace is the real story. Bitmine has accelerated its buying for four consecutive weeks, scaling from a prior weekly average of 45,000–50,000 $ETH to more than double that rate.

That is textbook accumulation behavior — not distribution.

As recently as May 5, Onchain Lens confirmed Bitmine staked an additional 157,344 $ETH worth approximately $372 million — pushing total staked holdings to 4.71 million $ETH.

Two newly created wallets simultaneously withdrew 40,000 $ETH from Kraken, likely p further accumulation.

Chairman Tom Lee put it plainly: “$ETH is in the final stages of the mini-crypto winter.” He cited $ETH’s outperformance of equities since the Iran conflict began, growing tokenization demand, and agentic AI systems increasingly running on Ethereum as the core conviction behind the strategy.

BlackRock Is Accumulating Too — Just More Quietly

On May 1 alone, BlackRock’s ETHA recorded $43.2 million in single-day inflows. Combined with Fidelity’s FETH adding $49.4 million on the same day, the two firms accounted for over 90% of total U.S. spot Ethereum ETF inflows — a $101.2 million single-day session that marked one of the strongest institutional moves into $ETH in weeks.

BlackRock is not buying $ETH directly. It is building a pool of institutional demand through a regulated wrapper — and that pool is growing steadily. The approach is quieter. The scale is different. But the direction is identical.

The Supply Picture Is Getting Tighter

The $ETH Exchange Supply Ratio has dropped to 0.122 — the lowest level since 2016. Exchange supply has been falling even as buyers absorb every offer.

When significant portions of an asset move into long-term staking and institutional custody, circulating liquidity declines — a dynamic that tightens market conditions precisely during periods of rising demand.

Bitmine is removing $ETH from circulation through staking. BlackRock is channelling institutional capital through ETFs.

Two-thirds of Bitmine’s entire stack is locked in staking — a structural bid that does not show up on order books but is felt in every sell-side attempt to push price lower.

The competition between these two approaches is real. And Ethereum sits at the centre of both.
