Ethereum News Today: ARK Bets Big on Ethereum’s Future, Stacking $8.3B in Ether Holdings

ARK Invest, the investment firm led by Cathie Wood, has increased its exposure to crypto-related equities, acquiring $23.5 million in shares of BitMine Immersion Technologies and Bullish across its flagship ETFs—ARKK, ARKW, and ARKF. According to trade filings, the purchases consisted of 387,000 shares of BitMine and 144,000 shares of Bullish. ARK Innovation ETF (ARKK) led the way, acquiring the largest portions of both stocks [3].

The move reflects ARK’s ongoing strategy to position its funds in the crypto ecosystem, as it continues to restructure its portfolio by reducing stakes in traditional tech stocks such as DraftKings, Roku, and Roblox. The firm has previously demonstrated a strong commitment to crypto assets, having invested $172 million in Bullish shares during the company’s IPO in August 2025 [2]. Bullish, which operates a global crypto exchange and owns CoinDesk, has maintained regulatory operations in multiple jurisdictions, including Hong Kong, the UK, and Singapore [3].

BitMine, the largest corporate holder of Ether, has also seen a surge in institutional interest. The company recently acquired an additional $65 million in ETH, raising its total holdings to more than 1.5% of Ethereum’s circulating supply [3]. BitMine’s Ethereum treasury now exceeds $8.3 billion, making it one of the most significant institutional holders of the asset. This strategic accumulation aligns with BitMine’s long-term investment narrative, emphasizing Ethereum’s potential as a foundational element of the future financial system [4].

BitMine has further reinforced its commitment to Ethereum by appointing industry veteran David Sharbutt to its board, potentially enhancing governance and attracting institutional support [6]. Despite recent share price declines, the company continues to attract investor attention, with its stock rebounding 5.58% on Wednesday following the announcement of increased ETH holdings [4].

Bullish also experienced a notable performance boost, with its shares rising 6% on Friday, following continued market momentum after its IPO. The firm’s stock had surged 83.8% during its IPO session in August, raising $1.1 billion and becoming one of the most anticipated crypto-related listings of the year [3]. ARK’s decision to increase its Bullish stake is seen as a strategic move to capitalize on the firm’s growing influence in the crypto market [2].

The recent investments by ARK underscore a broader trend of institutional adoption in the crypto space, as both companies and investment firms continue to explore the potential of digital assets as part of their long-term strategies. BitMine and Bullish have positioned themselves at the forefront of this movement, with their activities contributing to a tighter supply of Ether and a growing institutional interest in Ethereum-based products [3].
