Ethereum News Today: ARK's Ethereum Shift Signals Institutional Embrace of Crypto Treasuries

ARK Invest, managed by Cathie Wood, has significantly reshaped its portfolio by selling $31.94 million in Tesla Inc. shares on November 7, 2025, and redirecting capital toward BitMine Immersion Technologies, a firm transitioning into an Ethereum (ETH) treasury strategy according to CoinCentral. The sale of 71,638 Tesla shares marks a continued reduction in ARK's exposure to the electric vehicle giant, a top holding since 2018. Instead, the firm purchased 48,454 BitMine shares across three ETFs-ARK Next Generation Internet, ARK Innovation, and ARK Fintech Innovation-valued at approximately $2 million.

BitMine's stock surged 7.65% post-announcement, though the company faces $2.1 billion in unrealized losses on its ETH holdings due to recent price declines.

BitMine, led by Wall Street strategist Thomas Lee, has become a major ETH treasury player, holding 3.5 million ETH (2.9% of the circulating supply) as of November 2025. The firm's aggressive buying spree, including 110,288 ETH added in the week leading to November 10, underscores its strategy to accumulate 5% of ETH's supply. Lee framed the purchases as opportunistic, leveraging price volatility to secure assets at "substantial discounts to fundamentals". BitMine's treasury now ranks as the largest ETH holding globally, surpassing competitors like SharpLink Gaming and The Ether Machine.

ARK's investment aligns with BitMine's pivot to Ethereum, which the firm began in June 2025. The move reflects growing institutional confidence in crypto treasuries as structured investment vehicles. ARK's purchase of 240,507 BitMine shares -split across its flagship funds- signals a strategic bet on Ethereum's long-term value, despite short-term market turbulence. However, BitMine's challenges persist: its $398 million cash reserves and $2.1 billion in ETH losses highlight the risks of crypto's volatility.

Beyond BitMine, ARK diversified its holdings by acquiring $14.51 million in Trade Desk Inc. shares and $12 million in Bullish crypto exchange stock, ahead of Bullish's November 19 earnings report. The firm also increased biotech stakes in Intellia Therapeutics and Twist Bioscience, while offloading shares in GitLab, Roku, and Iridium Communications according to CoinCentral. These moves underscore ARK's broader shift toward sectors like digital advertising and crypto, betting on innovation-driven growth.

The Ethereum market itself remains mixed. While BitMine's accumulation has pushed ETH prices above $3,500, institutional and retail demand remains subdued amid macroeconomic uncertainties. ETF outflows and reduced open interest in Bitcoin and ETH futures suggest cautious sentiment according to FXStreet. Yet, BitMine's success in securing yield through staking and partnerships - such as its $200 million Linea Layer 2 deployment - demonstrates crypto treasuries' potential to bridge traditional finance and decentralized ecosystems.

ARK's portfolio adjustments reflect a broader trend: institutional investors are increasingly treating cryptocurrencies as corporate assets rather than speculative tokens. As BitMine's treasury grows, its ability to generate returns through staking and strategic partnerships will be critical to validating this approach. For now, the firm's 2.9% ETH stake and ARK's backing position it as a key player in Ethereum's evolving landscape according to Coindesk.
