Based on BMNR’s $15.79 closing price, the purchase was worth approximately $83,100. The position represented roughly 0.0014% of ARKK’s portfolio, making it a small allocation within the fund but another addition to ARK’s crypto-linked investment exposure.
BitMine has positioned itself as an Ethereum treasury company, placing ARK’s purchase alongside its wider investments in publicly traded firms connected to digital assets.
The transaction was part of a broader ARKK rebalance that also included additional purchases of X-Energy shares and sales of Figma stock. ARK also sold shares of Strata Critical Medical, ATAI Life Sciences and Elbit Systems across its funds, according to the disclosures.
3iQ Solana Staking ETF receives $168K allocation
ARK’s ARK Next Generation Internet ETF (ARKW) and ARK Fintech Innovation ETF (ARKF) also increased their holdings in the 3iQ Solana Staking ETF, which trades under the ticker SOLQ.U.
ARKW purchased 16,917 shares, worth about $101,700 at Friday’s close. ARKF added 11,101 shares, valued at approximately $66,700.
Together, the two funds acquired 28,018 SOLQ.U shares worth around $168,400. The purchases came as the Solana-based investment product declined $0.13, or 2.12%, to close at $6.01 on Friday.
The move gives ARK further exposure to Solana through an exchange-traded product that includes staking-related exposure, rather than a direct purchase of $SOL tokens.
ARK’s crypto and AI buying spree continues
Friday’s trades followed a more active week for ARK Invest, which bought nearly $60 million in Tesla, Circle Internet Group and Securitize shares on Thursday amid a broader U.S. equity market sell-off.
Tesla accounted for more than $51 million of that total, according to the firm’s daily trade reports. ARK also added roughly $14 million in SpaceX stock earlier in the week.
Outside crypto-related holdings, Friday’s filings showed new purchases of Pony AI, Kodiak AI, Scribe Therapeutics and Compass Pathways. The transactions point to continued portfolio adjustments across artificial intelligence, healthcare and digital-asset-linked companies.
What it means for U.S. investors
ARK Invest’s latest activity offers U.S. investors another snapshot of how one of the country’s best-known thematic ETF managers is approaching crypto exposure.
The purchases were modest relative to ARK’s overall assets, but they spread exposure across two distinct parts of the market: BitMine’s Ethereum treasury strategy and a Solana staking-focused ETF product.
U.S. investors considering similar exposure should note that ARK’s purchases do not amount to a forecast on either asset. They instead show the firm’s continued use of public equities and exchange-traded products to gain exposure to crypto-related themes while it also rotates positions in technology and AI stocks.
