Cathie Wood’s ARK Invest has expanded its crypto-related holdings with fresh stakes in BitMine Immersion Technologies and the 3iQ Solana Staking ETF, committing around $251,500 across three of its exchange-traded funds.
The latest daily trade disclosures show that ARK’s flagship ARK Innovation ETF (ARKK) bought 5,264 shares of BitMine Immersion Technologies (BMNR) on Friday. Based on BitMine’s closing price of $15.79, the purchase was valued at roughly $83,100.
That new position represents about 0.0014% of ARKK’s portfolio – a small allocation in percentage terms, but one that adds to ARK’s growing collection of crypto-linked equity positions. BitMine describes itself as an Ethereum treasury company, meaning ARK’s move fits within its strategy of backing publicly listed firms with direct ties to digital assets.
Solana exposure increased via ETF
Alongside the BitMine trade, ARK also lifted its exposure to Solana through the 3iQ Solana Staking ETF, which trades under the ticker SOLQ.U.
The ARK Next Generation Internet ETF (ARKW) acquired 16,917 SOLQ.U shares on Friday, worth about $101,700 at the closing price. The ARK Fintech Innovation ETF (ARKF) added a further 11,101 shares, valued at approximately $66,700.
In total, ARKW and ARKF bought 28,018 shares of SOLQ.U, for a combined outlay of around $168,400. The purchases came on a day when the Solana-based product fell $0.13, or 2.12%, to finish at $6.01.
By using SOLQ.U, ARK is gaining additional Solana exposure via an exchange-traded product that incorporates staking-related returns, rather than holding SOL tokens directly.
Broader portfolio reshuffle
The BitMine investment formed part of a wider reshuffle within ARKK. Friday’s trades included further buying of X-Energy shares, while ARK trimmed its holdings in Figma. Across its funds, the firm also sold positions in Strata Critical Medical, ATAI Life Sciences and Elbit Systems, according to the disclosures.
Beyond crypto-linked names, ARK’s filings for Friday highlighted new positions in Pony AI, Kodiak AI, Scribe Therapeutics and Compass Pathways. These moves indicate continued rotation within the portfolio across artificial intelligence, healthcare and other high-growth, innovation-focused sectors.
Busy week following market sell-off
Friday’s activity followed a particularly active spell for ARK Invest earlier in the week, set against a broader sell-off in U.S. equities.
On Thursday, ARK disclosed purchases of nearly $60 million in Tesla, Circle Internet Group and Securitize shares. Tesla accounted for more than $51 million of that total, according to the firm’s daily trade reports, underlining its continued importance within ARK’s thematic strategies.
Earlier in the week, ARK also added approximately $14 million in SpaceX stock, extending its exposure to the private space company that has become a prominent holding across a number of institutional portfolios.
Measured move into crypto themes
While the latest crypto-related trades are small in the context of ARK’s total assets under management, they underscore the firm’s continued interest in digital-asset themes through listed securities and exchange-traded products.
The BitMine stake offers targeted exposure to an Ethereum-focused treasury model, while the 3iQ Solana Staking ETF provides access to Solana with a staking component embedded in the product structure.
For U.S. investors watching ARK’s activity as a barometer of institutional sentiment, the firm’s latest moves do not constitute a directional call on Ethereum or Solana prices. Instead, they illustrate how one of the best-known thematic ETF managers in the U.S. is using public markets to express long-term views on crypto, even as it simultaneously rotates capital among technology, AI and healthcare stocks.
