Ethereum Empire: Bitmine's $10.7B Accumulation Strategy Fuels Institutional Buying Spree

Bitmine Immersion Technologies (NYSE: BMNR) has been quietly building the largest Ethereum treasury in history, holding 5,672,956 ETH worth approximately $9.83 billion as of June 21, 2026.

This represents 4.7% of the global circulating supply and puts Bitmine at the world's #1 Ethereum corporate treasury and the global #2 crypto treasury, trailing only Strategy Inc.'s holdings of 846,842 BTC valued at approximately $54 billion.

The timing is striking, as Ethereum's Glamsterdam upgrade has been delayed to H2 2026, removing a key short-term price catalyst. Yet institutional investors such as ARK Invest (Cathie Wood), Pantera Capital, and Galaxy Digital are not just holding, they are aggressively buying more ETH.

Bitmine's accumulation strategy is centered around its MAVAN staking platform, which has staked 4,718,677 ETH, generating projected annualized staking revenue of $223 million. This is not a speculative bet on price appreciation but rather a cash-flow business built on top of Ethereum's proof-of-stake protocol.

Institutional backers include ARK Invest (Cathie Wood), Pantera Capital, Founders Fund, Kraken, DCG, and Galaxy Digital, providing both capital and credibility to Bitmine's long-term accumulation strategy. The institutional interest extends beyond Bitmine, with corporate ETH treasury holdings across all public entities surpassing 6.2 million ETH by early 2026.
