BlackRock Increases BMNR Holdings By 165% As Cathie Wood's Ark Invest Adds $4.2M

BitMine Immersion Technologies (NYSE:BMNR) rose 1.5% after BlackRock (NYSE:BLK) disclosed a 165.6% stake increase, adding to the $4.2 million BMNR shares purchase by Cathie Wood’s Ark Invest.

The Institutional Buying

BlackRock’s 13F-HR filing showed ownership jumped from 3.4 million shares to 9 million shares as of December 31, 2025, valued at $245.7 million. 

The asset manager increased its stake despite BitMine’s massive unrealized losses from Ethereum’s crash.

Additionally, Cathie Wood’s Ark Invest bought 212,314 shares across three ETFs on Thursday, expanding crypto exposure as BMNR trades 36.7% lower over the past month. 

The ETH Holdings

BitMine added 40,613 ETH in the past week.

As of February 8, BitMine holds 4,325,738 ETH at $2,125 per ETH, representing 3.58% of total ETH supply. 

The company also holds 193 Bitcoin (CRYPTO: BTC), a $200 million stake in Beast Industries, $19 million in Eightco Holdings (NASDAQ:ORB), and $595 million cash.

Chairman Tom Lee blamed non-fundamental factors for ETH weakness.

Leverage hasn’t returned after October’s $19 billion market wipeout, and the surge in precious metals acted as a “vortex” sucking risk appetite from crypto.

BMNR Technical Setup

BMNR closed Thursday up 1.4% and is trading 1.5% higher in premarket at $20.05, consolidating near critical support.

The stock hovers just above the lower Bollinger Band at $16.15, suggesting oversold conditions.

For bulls, BMNR needs to hold above $18-$19 and break decisively above $20. Immediate resistance appears at the middle Bollinger Band around $25, followed by the Supertrend at $25.59.
