Tom Lee's Bitmine ETH Holdings Hit $10B

Bitmine Closes In on Its 5% Ethereum Target

Bitmine Immersion Technologies (NYSE: BMNR), the Ethereum treasury firm chaired by @Fundstrat co-founder Tom Lee, has added another 52,203 $ETH worth approximately $92 million to its holdings, taking its total position to 5,672,956 ETH valued at roughly $10 billion. The firm is now 94% of the way toward its self-described "Alchemy of 5%" goal: owning 5% of Ethereum's total supply as a long-term reserve asset.

The milestone caps months of aggressive accumulation. Bitmine reached the 5-million-ETH mark in roughly ten months, after pivoting to a digital asset treasury strategy from its earlier roots as a Bitcoin miner. The company uplisted to the New York Stock Exchange from NYSE American on April 9, and counts ARK's Cathie Wood, Founders Fund, Pantera, Kraken, and Galaxy Digital among its institutional backers.

Bitmine's total crypto and cash holdings now stand at $10.7 billion. Of its ETH stack, 4,718,677 tokens, worth $8.2 billion at $1,733 per $ETH, are actively staked. The firm has staked more than 4.7 million ETH, roughly 87% of its holdings, generating approximately $276 million in annualized staking revenue. That yield is generated through MAVAN, the company's Made in America Validator Network, an institutional-grade staking platform built for security, performance, and resilience.

A $9 Billion Paper Loss and the Bull Case Behind It

The accumulation has not been painless. Ethereum is still trading roughly 64% below its all-time high of $4,946 reached in August 2025, meaning Bitmine is sitting on estimated unrealized losses of around $9 billion.

Lee has been unapologetic about buying into that weakness. He argues that Ethereum is benefiting from two long-term trends: the shift of financial assets onto blockchain rails through tokenization, and the rise of artificial intelligence tools that will seek neutral, public networks for payments and verification. In earlier updates, Lee said "Crypto Spring, in our view, has commenced," noting that investor sentiment remains muted even as crypto prices strengthen.

Critics have raised questions about concentration risk and the potential for a feedback loop. Lee is simultaneously chairman of Bitmine and founder of Fundstrat, whose research channels regularly amplify the company's milestones, a dynamic some argue creates a conflict between research output, public messaging, and treasury moves. There are also structural concerns: a single entity approaching 5% of a network's supply becomes a force capable of influencing validator dynamics, governance, and liquidity.

With the 5% threshold now within reach, the market will be watching closely what Bitmine does once the buying stops, and whether the staking yield alone justifies the scale of the bet.
