BitMine Corners 3.4% of Ethereum Supply with $98M ‘Year-End’ Buy

Contrarian Accumulation Amidst Tax Sell-Off

BitMine Immersion Technologies (NYSE: BMNR) executed a $97.6 million purchase of 32,938 Ether (ETH) this week, aggressively capitalizing on low liquidity and tax-loss harvesting in the final days of 2025. The acquisition reinforces the company’s pivot to a treasury-first model, bringing its total holdings to 4.07 million ETH, valued at approximately $12 billion.

While broader crypto markets struggled under the weight of year-end selling pressure, BitMine has purchased over 40,000 ETH weekly for ten consecutive weeks. The firm now controls roughly 3.4% of the entire circulating Ethereum supply, a concentration of wealth that rivals major exchange wallets.

The ‘Fresh Money’ Strategy

The accumulation is orchestrated by BitMine Chairman Tom Lee, who identified the current market compression as a temporary distortion caused by U.S. tax-loss selling and institutional holiday absences. Lee described the firm’s role as the market’s primary liquidity provider during this lull.

“Year-end tax-loss related selling is pushing down crypto… so we are navigating markets with this in mind. [BitMine remains] the largest ‘fresh money’ buyer of ETH in the world.”, Tom Lee, Fundstrat / BitMine Chairman

Despite the aggressive buy-side pressure from BitMine, Ether struggled to reclaim the psychological $3,000 level, trading near $2,960 as volumes thinned. The disconnect between BitMine’s accumulation and spot price action suggests the market has yet to price in the supply shock of removing 77,400 ETH from circulation in just 10 days.

Institutional Context

BitMine’s strategy mirrors the “Bitcoin Standard” playbook but applied to Ethereum’s yield-bearing ecosystem. By locking nearly $12 billion in ETH, the company is effectively betting on a supply squeeze in early 2026 once institutional trading desks return and tax selling abates. The market now watches to see if this relentless buying floor can withstand potential January liquidation cascades.
