Following ARK’s investment announcement, BitMine shares jumped 7.65% to reach $40.23 in after-hours trading. The stock has climbed 415% since the start of 2025.
However, BitMine faces challenges with its crypto holdings. Data from CryptoQuant shows the company has approximately $2.1 billion in unrealized losses on its Ether positions due to recent declines in digital asset values.
ARK has been steadily increasing its BitMine stake since April 2025. This timing coincided with BitMine’s expected transition to its Ethereum treasury model.
The Tesla sale occurred after shareholders approved a compensation package for CEO Elon Musk. About 75% of voting shares supported the proposal despite objections from major proxy advisors ISS and Glass Lewis.
The package consists of 12 stock tranches tied to performance targets ranging from a $2 trillion market cap to $8.5 trillion. Musk announced plans to increase his company stake from 13% to 25%.
ARK made its largest single purchase of the day in Trade Desk Inc, acquiring 316,072 shares valued at $14.51 million. The buy signals growing interest in the digital advertising sector.
The firm also purchased 238,000 shares of Bullish crypto exchange worth roughly $12 million. The purchases were split across multiple funds, with ARK Innovation ETF buying 164,214 shares.
Bullish will report third-quarter earnings on November 19. The exchange posted $57 million in adjusted revenue during Q2 2025, down from $67 million in Q2 2024.
Net income for Bullish reached $108.3 million in Q2 2025. This marked a turnaround from a $116.4 million net loss in the same quarter of 2024.
ARK has accumulated approximately $172 million worth of Bullish shares since the exchange went public on the New York Stock Exchange at a $1.1 billion valuation. The firm continues adding to this position through regular purchases.
Wood’s firm also increased its biotech holdings by purchasing 1,046,699 shares of Intellia Therapeutics worth $12.90 million. Additional buys included $4.28 million in Beam Therapeutics and $4 million in Twist Bioscience.
