Cathie Wood's Ark and BlackRock Significantly Expand BMNR Positions As Crypto Holdings Strengthen

BitMine Immersion Technologies (NYSE: BMNR) climbed 1.5% as two major institutional players revealed aggressive position increases in the digital asset-focused company. BlackRock, the world’s largest asset manager, nearly tripled its BMNR holding through December 31, 2025, while investment powerhouse Cathie Wood’s Ark Invest simultaneously added $4.2 million in shares. This synchronized institutional accumulation signals growing confidence in BitMine’s strategic crypto holdings despite recent market volatility.

Major Players Expand Stakes: BlackRock and Cathie Wood Lead Charge

BlackRock’s 13F-HR filing disclosed a dramatic 165.6% stake increase, with holdings surging from 3.4 million shares to 9 million shares valued at $245.7 million as of year-end 2025. The world’s largest asset manager deepened its commitment despite BitMine facing substantial paper losses from Ethereum’s recent downturn.

Cathie Wood’s Ark Invest moved in concert with this institutional trend, accumulating 212,314 BMNR shares across three ETFs in recent weeks. The dual positioning from both BlackRock and Ark Invest underscores their conviction in BitMine as a proxy for long-term cryptocurrency exposure. At the time of these purchases, BMNR had declined 36.7% over the preceding month, suggesting both institutions view the weakness as a buying opportunity.

Fortress-Like ETH Position Anchors BitMine’s Strategy

BitMine’s crypto exposure extends well beyond stock price fluctuations. The company bolstered its Ethereum holdings by 40,613 ETH in recent trading, bringing its total ETH reserves to 4,325,738 coins—representing 3.58% of total Ethereum supply. At $2,125 per ETH as of February 8, this positions BitMine as one of the cryptocurrency sector’s most substantial institutional holders.

Beyond Ethereum, BitMine maintains a diversified crypto and equity portfolio: 193 Bitcoin ($200 million equivalent), $19 million in Eightco Holdings (NASDAQ: ORB) shares, $595 million in cash reserves, and a $200 million stake in Beast Industries. This balanced allocation drew analysis from Chairman Tom Lee, who attributed recent Ethereum weakness to “non-fundamental factors.” Lee noted that residual risk aversion from October’s $19 billion market destruction persists, with precious metals accumulation acting as a portfolio “vortex” redirecting capital away from digital assets.

Technical Foundation Supports Further Upside Potential

BMNR closed Thursday’s session up 1.4% and entered premarket trading 1.5% higher at $20.05, consolidating above critical support levels. The stock currently trades just above its lower Bollinger Band at $16.15, positioning it in technically oversold territory that often precedes rebounds.

For bulls to regain momentum, BMNR must establish resistance above the $18-$19 zone and break decisively through $20. The immediate overhead resistance cluster emerges around the middle Bollinger Band near $25, with the Supertrend indicator plotting resistance at $25.59. The current consolidation phase, combined with institutional accumulation from Cathie Wood’s team and BlackRock, suggests the foundation for potential recovery has formed.
