ARK Invest Boosts BitMine Stake as Stock Soars 415%

According to ARK Invest’s daily trading disclosures dated Friday, the firm purchased a combined 48,454 shares of BitMine worth approximately $2 million across three of its exchange-traded funds. The investment was distributed through the ARK Innovation ETF (ARKK), the ARK Fintech Innovation ETF (ARKF), and the ARK Next Generation Internet ETF (ARKW), demonstrating a coordinated approach to increasing exposure to the crypto-focused firm. This move comes alongside a reduction in ARK’s Tesla (TSLA) position, signaling a strategic reallocation within Wood’s investment portfolio toward companies with significant cryptocurrency exposure.

The timing of this investment coincides with BitMine’s remarkable 415% stock surge in 2025, following the company’s decision to begin accumulating Ethereum (ETH) as a treasury asset in April. ARK Invest has been progressively building its position in BitMine since the firm initiated its Ether treasury strategy, indicating Wood’s confidence in companies that incorporate cryptocurrency into their corporate treasury management. This consistent accumulation pattern suggests ARK views BitMine’s crypto strategy as a long-term value proposition rather than a short-term speculative play.

BitMine, led by Tom Lee, has distinguished itself in the traditional finance space by aggressively accumulating Ethereum as part of its treasury asset management strategy. The company began this approach in April 2025, positioning itself at the intersection of traditional finance (tradfi) and cryptocurrency markets. This strategic move has proven exceptionally successful, with the firm’s stock experiencing a 415% surge throughout 2025, significantly outperforming broader market indices and capturing the attention of major institutional investors like ARK Invest.

The substantial stock performance reflects growing investor confidence in companies that integrate cryptocurrency into their core financial strategies. BitMine’s approach mirrors similar treasury strategies employed by other forward-thinking corporations, but with a focused emphasis on Ethereum rather than Bitcoin. This differentiation appears to have resonated with Cathie Wood’s investment philosophy, which has consistently emphasized disruptive innovation and technological transformation across multiple sectors, including blockchain and cryptocurrency infrastructure.

Cathie Wood’s ARK Invest has been steadily increasing its exposure to cryptocurrency-related assets, with the BitMine investment representing the latest in a series of strategic moves into the digital asset space. The allocation across three different ETFs—ARKK, ARKF, and ARKW—demonstrates Wood’s conviction that cryptocurrency exposure belongs in multiple innovation-focused portfolios rather than being siloed into a single fund. This diversified approach to crypto investment within the ETF structure allows ARK to capture upside potential while managing sector-specific risks.

The reduction in Tesla holdings to fund the BitMine investment suggests Wood sees greater near-term potential in pure-play crypto treasury companies than in electric vehicle manufacturers with incidental crypto exposure. This reallocation reflects evolving investment priorities within ARK’s innovation-focused strategy, where direct crypto exposure may be gaining preference over tangential blockchain involvement. Wood’s continued accumulation of BitMine shares since April indicates a calculated, phased approach to building positions in companies that successfully integrate cryptocurrency into their business models.

This investment strategy aligns with ARK’s historical pattern of identifying and backing disruptive technologies before they achieve mainstream adoption. The firm’s willingness to reallocate from established positions like Tesla to newer opportunities like BitMine demonstrates Wood’s commitment to her investment philosophy, even when it requires reducing exposure to previous success stories. As cryptocurrency continues to mature as an asset class, ARK’s strategic moves provide valuable insight into how sophisticated institutional investors are positioning themselves within the evolving digital asset landscape.
