Portfolio adjustment at Ark Invest involves adding shares of Coinbase and Block.
In a significant move, Ark Invest, a prominent investment management firm, has announced a strategic portfolio rebalancing. This rebalancing involves the sale of substantial shares in crypto-linked financial companies like Coinbase, Block Inc., and Robinhood Markets, while significantly increasing exposure to Bitmine, a blockchain infrastructure company with a large Ethereum treasury.
This shift reflects a pivot from crypto exchanges and fintech towards firms with direct crypto network exposure. In mid-to-late July 2025, Ark Invest sold over $22 million worth of shares in Coinbase, Block Inc., and Robinhood Markets. The sale included $12.1 million in Coinbase shares across the ARK Innovation ETF (ARKK) and ARK Next Generation Internet ETF (ARKW), $9.8 million in Block Inc. shares sold in ARKK, and approximately $1.1 million in Robinhood Markets shares sold in ARKW.
Following Coinbase’s stock reaching a record high of $444.65 on July 18, Ark Invest further offloaded more than $105 million in Coinbase shares to take profits.
On the other hand, Ark Invest has increased its investment in Bitmine by nearly $175-$182 million, adding this position across multiple ETFs. Bitmine Immersion is noted for holding over $1 billion in Ethereum assets, aligning with Ark’s focus on crypto infrastructure with substantial token reserves.
Ark Invest follows a portfolio rule limiting any single stock to 10% of a fund's holdings, prompting these rebalances to manage risk and maintain diversification.
Ark Invest also acquired 140,000 eToro shares for its ARK Fintech Innovation ETF (ARKF), valued at approximately $9.4 million. However, the firm sold a total of 342,658 Circle (CRCL) shares across its three actively managed ETFs. Within a few days, Ark Invest sold 196,367 Circle shares from ARKK, 92,310 from ARKW, and 53,981 from ARKF. At the time, Circle made up 6.7% of Ark's holdings and ranked among the top positions across three of its funds.
This recent rebalancing shows Ark Invest is reducing stakes in crypto exchanges and fintech companies (Coinbase, Block, Robinhood) and boosting exposure to Ethereum-focused blockchain infrastructure firms like Bitmine, reflecting a strategic shift toward assets with direct cryptocurrency network involvement amid market volatility.
- In line with their strategic focus on cryptocurrency network exposure, Ark Invest has been actively increasing its investment in technology-driven companies like Bitmine, which holds over $1 billion in Ethereum assets.
- To manage risk and maintain diversification, Ark Invest has been reducing its stakes in finance-related sectors, such as crypto exchanges and fintech companies like Coinbase, Block Inc., and Robinhood Markets, and instead investing in promising tech firms with a strong connection to the cryptocurrency network.
