Based on BMNR’s closing price of $15.79, the purchase price is worth approximately $83,100. This position represents approximately 0.0014% of ARKK’s portfolio, and although it is a small allocation within the fund, it is a new addition to ARK’s crypto-related investment exposure.
BitMine is positioning itself as an Ethereum finance company and is positioning the acquisition of ARK alongside its extensive investments in public companies related to digital assets.
The transaction was part of a broader ARKK rebalance that included the purchase of additional X-Energy stock and the sale of Figma stock. ARK also sold shares in Strata Critical Medical, ATAI Life Sciences and Elbit Systems across funds, according to the disclosure.
3iQ Solana Staking ETF receives $168,000 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 approximately $101,700 as of Friday’s close. ARKF added 11,101 shares worth approximately $66,700.
Together, the two funds acquired 28,018 SOLQ.U shares worth approximately $168,400. The buying came after Solana-based investment products fell $0.13, or 2.12%, to close at $6.01 on Friday.
This move will allow ARK to further increase its exposure to Solana through exchange-traded products, including staking-related exposure, rather than purchasing Solana directly. $SOL token.
ARK’s hoarding of cryptocurrencies and AI continues
Friday’s trading followed a more active week for ARK Investments, which bought nearly $60 million in Tesla, Circle Internet Group and Securitize stock on Thursday amid a broader decline in the U.S. stock market.
Tesla accounted for more than $51 million of this total, according to the company’s daily trading report. ARK also added about $14 million in SpaceX stock earlier this week.
In addition to crypto-related holdings, Friday’s filing also shows new purchases in Pony AI, Kodiak AI, Scribe Therapeutics and Compass Pathways. The deal signals continued portfolio adjustments across artificial intelligence, healthcare, and digital asset companies.
What it means for US investors
ARK Invest’s latest activity provides U.S. investors with another snapshot of how one of the country’s most prominent thematic ETF managers is approaching crypto exposure.
While the purchase price was modest compared to ARK’s overall assets, it widened its exposure to two distinct parts of the market: Bitmine’s Ethereum financial strategy and Solana’s staking-focused ETF product.
US investors looking for similar exposure should be aware that purchasing ARK does not fit into the forecast for either asset. Instead, it shows the company continues to use public stocks and products to gain exposure to crypto-related themes, while rotating its positions in technology and AI stocks.
