Cathie Wood’s ARK ETFs have made significant moves in the stock market on Friday, August 1, 2025, with a particular focus on tech and biotech companies. Leading the trades was a massive purchase of Coinbase Global Inc (NASDAQ:COIN) shares, signaling a bullish stance on the cryptocurrency exchange platform.
ARK’s investment in Coinbase involved an acquisition of 94,678 shares across three of its funds: ARKK, ARKW, and ARKF. With a total dollar value of $35,765,561, this trade stands out as the highest value transaction for the day. The consistent buying pattern in Coinbase over recent days suggests ARK’s growing confidence in the company’s future.
Another notable trade was the purchase of 540,712 shares of Bitmine Immersion (NASDAQ:IMMR) Technologies Inc (OTC:BMNR), a company specializing in cryptocurrency mining technology. The shares, valued at $18,730,263, were distributed amongst ARKK, ARKW, and ARKF, indicating a diversified investment strategy across the ARK funds.
On the other side of the spectrum, ARK divested a significant portion of its holdings in Roblox Corp (NYSE:RBLX), selling 353,530 shares through ARKK, ARKW, and ARKF for a total of $48,712,898. This sale marks a substantial move away from the online gaming platform.
ARK also continued to adjust its biotech portfolio, with a sale of 39,393 shares of Adaptive Biotechnologies Corp (NASDAQ:ADPT) for $403,384 through its ARKG fund. This follows a trend of reducing exposure to Adaptive Biotechnologies, as seen in previous trading sessions.
In addition to these major trades, ARK made strategic purchases in Roku Inc (NASDAQ:ROKU), buying 342,933 shares for $32,290,571, and Illumina Inc (NASDAQ:ILMN), adding 162,211 shares for $17,284,224. Both companies have been on ARK’s radar, with consistent buying indicating a long-term investment perspective.
The sale of Kratos Defense and Security Solutions Inc (NASDAQ:KTOS) shares was another significant move, with 134,548 shares sold for $7,897,967 through the ARKK ETF. This defense contractor has seen a reduction in ARK’s investment, aligning with the fund’s focus on innovation and technology.
Smaller trades included buying 23,173 shares of Compass Pathways PLC (NASDAQ:CMPS) for $100,802 and 39,2623 shares of PagerDuty Inc (NYSE:PD) for $6,329,082. ARK also sold smaller positions in Ionis Pharmaceuticals Inc (NASDAQ:IONS), 908 Devices Inc (NASDAQ:MASS), and continued to offload Kratos Defense and Security Solutions Inc (NASDAQ:KTOS) shares.
Overall, Cathie Wood’s ARK ETFs remain active in the market, with a clear emphasis on companies at the forefront of technological and scientific innovation. Investors continue to watch ARK’s trades closely, as they can provide insights into the emerging trends and sectors that may shape the future of the economy.
