Bitmine's $11.3B Crypto Treasury: 4.8% of All ETH and Russell 1000 Boost

For investors tracking the collision of traditional equity indices and digital asset treasuries, Bitmine Immersion Technologies' latest disclosure marks a new phase in institutional-grade crypto exposure. With $11.3 billion in total holdings—over 90% in Ethereum—and a July 12 snapshot timed just after its Russell 1000 inclusion, the company's balance sheet is about to become a barometer for passive index flows pouring into a crypto-native equity.

On July 13, 2026, Bitmine Immersion Technologies (NYSE: BMNR) disclosed a corporate treasury of staggering scale: $11.3 billion in combined crypto assets, cash, marketable securities, and private equity stakes, anchored by 5.77 million Ether tokens. The disclosure, made via press release, positions Bitmine as the single largest known corporate holder of ETH, controlling 4.8% of the entire Ethereum supply of 120.7 million coins. Of that, 4.92 million ETH—worth $9.0 billion at the quoted price of $1,820—is actively staked through the company's proprietary MAVAN (Made in America VAlidator Network), turning Bitmine into a dominant validator on the Ethereum network and generating ongoing staking rewards. The remainder of the portfolio includes 206 Bitcoin, a $180 million stake in Beast Industries, $69 million in Eightco Holdings (moonshots), and $482 million in total cash and marketable securities, reflecting a deliberate strategy of deep exposure to the Ethereum ecosystem while maintaining a liquidity buffer.

With $11.3 billion in total holdings—over 90% in Ethereum—and a July 12 snapshot timed just after its Russell 1000 inclusion, the company's balance sheet is about to become a barometer for passive index flows pouring into a crypto-native equity.

This announcement is more than a balance-sheet update; it signals a maturation point for public-company crypto treasuries. At $1,820 per ETH, the market value of Bitmine's ETH alone exceeds the entire market capitalization of Midstream energy companies or many REITs, catapulting the firm from a niche crypto accumulator into a large-cap equity with significant passive-investment ramifications. The June 26 addition to the Russell 1000 Large-cap Index—confirmed in this release—is a pivotal catalyst. With index funds and ETFs that track the Russell 1000 estimated by the Investment Company Institute to represent 18–20% of total shares, Bitmine is suddenly on the radar of trillions of dollars in passive capital. The company itself projects this inclusion 'is expected to add hundreds of millions' in passive demand, and those flows could tighten the freely traded float of BMNR stock, amplifying upside if crypto markets continue to rally. Critically, this index effect arrives at a time when Ethereum's network utility is enjoying a headline-grabbing catalyst: the July 1 mainnet launch of Robinhood Chain, a Layer‑2 built on Arbitrum. Robinhood Chain has already processed over $1 billion in volume and become the top decentralized exchange by trading volume, according to the release, and it uses ETH as the native gas token. Bitmine Chairman Thomas Lee explicitly ties his company's accumulation thesis to this event, arguing that Robinhood's 27 million users are now transacting in ETH, thus 'everyday users are starting to see ETH as money.'
