A bet on Ethereum through BitMine
BitMine itself is one of the largest holders of Ethereum. Its ETH treasury is valued at $7.5 billion, making it the second-largest crypto treasury after Michael Saylor’s company, which leads in Bitcoin holdings. As a result, ARK’s large stake in BitMine can be seen as a direct bet on the future growth of ETH.
ARK also holds about $676 million worth of Coinbase stock. Now, BitMine has reached over half of that amount within ARK’s portfolio. This shows the rising importance of ETH-focused companies in ARK’s strategy.
Cathie Wood has always championed technologies like blockchain, gene editing, and artificial intelligence. ARK’s latest moves show that it sees ETH-focused businesses as key drivers of the next wave of financial innovation.
More crypto-related buys
BitMine is not the only crypto stock ARK has been collecting. The firm recently added $16.2 million in Robinhood shares and $21.2 million in Bullish shares. Earlier in August, ARK also purchased $19.2 million worth of Block (SQ) shares, after previously trimming its position.
As of Today, ARK’s total Robinhood holdings across its funds reached $543 million.
BitMine’s stock performance
However, BitMine’s stock saw a drop despite ARK’s strong buying. According to Google Finance, shares fell 8% on Wednesday to close at $46.03. They declined further in after-hours trading by 2.22% to $45.01.
Yet, the stock has had an outstanding year overall. It has surged 490% so far in 2025. BitMine’s financials are also improving. Its net profit margin jumped 43% in the quarter ending in May. Meanwhile, revenue hit $2.05 million, which is up 67.5% year-over-year.

ETH in Focus
ARK’s growing stake in BitMine signals its strong belief in Ethereum’s long-term future. More companies are now adopting ETH as a treasury asset. As a result, ARK is betting that Ethereum may follow Bitcoin’s path of adoption, or perhaps even surpass it, given ETH’s growing role in decentralized applications and corporate finance.
Cathie Wood’s firm shows no signs of slowing down. With more than $300 million already invested in BitMine, ARK looks ready to continue riding the Ethereum wave in the years ahead.
