Ethereum News Today: ARK Invest Bets Big on Ethereum’s Future with $23.5M BitMine Play

ARK Invest has acquired a $4.5 million stake in BitMine Immersion Technologies (BMNR), a prominent Ethereum treasury firm, through three of its actively managed exchange-traded funds (ETFs). The ARK Innovation ETF (ARKK), ARK Next Generation Internet ETF (ARKW), and ARK Fintech Innovation ETF (ARKF) collectively purchased 387,000 shares of BitMine at a cost of approximately $23.5 million. ARKK led the transaction by acquiring 257,108 shares, while ARKW and ARKF acquired the remaining shares. This move aligns with ARK Invest's broader strategy to bolster its exposure to blockchain-related equities. Simultaneously, the firm also trimmed its positions in several other technology stocks, including DraftKings, Roku, Roblox, and Teradyne [1].

BitMine, which is currently the largest Ethereum treasury firm globally, has significantly increased its ETH holdings. As of September 7, 2025, the company reported a total of 2,069,443 ETH in its treasury, valued at $4,312 per ETH (Bloomberg price index), in addition to 192 Bitcoin (BTC) and $266 million in unencumbered cash. This brings the total value of BitMine’s crypto and cash holdings to over $9.2 billion. The firm surpassed 2 million ETH in holdings, a milestone it has attributed to a growing trend of institutional adoption of blockchain and the emergence of a token-driven economy. BitMine remains the second-largest crypto treasury globally, trailing only Strategic Inc (MSTR), which holds 636,505 BTC valued at $71 billion [2].

In parallel, BitMine has announced its first strategic investment under its “Moonshot” strategy—a $20 million investment in Eightco Holdings Inc. (NASDAQ: OCTO). This investment is part of a broader initiative to support innovative projects that contribute to the Ethereum ecosystem. Eightco, an e-commerce company, has adopted a treasury strategy centered on Worldcoin (WLD), an ERC-20 token co-founded by OpenAI’s Sam Altman. BitMine’s investment is described as a “select investment in bold ideas” and is expected to strengthen the Ethereum network’s infrastructure. The company typically allocates approximately 1% of its balance to such strategic initiatives. BitMine’s Chairman, Thomas “Tom” Lee, emphasized that supporting projects aligned with Ethereum’s long-term vision is key to the network’s future growth [2].

BitMine’s shares have experienced mixed performance recently. Following the announcement of its investment in Eightco, OCTO’s shares surged more than 3,000% to $46.01 on the day of the announcement. In contrast, BMNR shares rose by approximately 0.5% in early trading but remained down roughly 18% over the past month. Despite this, BitMine continues to lead the Ethereum treasury space by a significant margin. The company holds more than twice the amount of ETH compared to its closest competitor, SharpLink Gaming, which has $3.63 billion in Ethereum holdings [2].

The growing institutional interest in BitMine is further underscored by the continued involvement of Cathie Wood and ARK Invest. Wood, known for her aggressive investment approach in high-growth technology sectors, has historically maintained a bullish stance on blockchain and artificial intelligence. Her strategy often involves increasing stakes in undervalued stocks and exiting positions as valuations climb. ARK Invest’s recent move to bolster its position in BitMine and Bullish, the parent company of CoinDesk, reflects the firm’s ongoing commitment to the crypto sector. The ETFs have previously invested heavily in crypto-related equities, with ARK having purchased $172 million worth of Bullish shares during its IPO in August 2025 [1].

BitMine’s strategic positioning in the blockchain space is further reinforced by its extensive network of institutional investors, including ARK’s Cathie Wood, MOZAYYX, Founders Fund, Bill Miller III, Pantera, Kraken, DCG, and Galaxy Digital. These investors support BitMine’s long-term goal of acquiring up to 5% of the total ETH supply. The company operates primarily in low-cost energy regions across Trinidad, Pecos, Texas, and Silverton, Texas, and is currently one of the most actively traded stocks in the U.S., with an average daily trading volume of $1.7 billion [2].
