Cathie Wood’s ARK buys Tempus AI stock, sells Block and Roku

Cathie Wood’s ARK ETFs disclosed their daily trades for Wednesday, July 9th, 2025, with a significant focus on the tech and healthcare sectors. In the largest transaction of the day, ARK increased its position in Tempus AI Inc (NYSE:TEM), purchasing 150,563 shares valued at approximately $8.8 million, with the bulk acquired through its flagship ARKK ETF and a smaller portion through its ARKG ETF.

This purchase marks a continuation of ARK’s interest in Tempus AI, a company that specializes in artificial intelligence for healthcare, and follows a trend of ARK’s investments in innovative tech firms. On the selling side, ARK reduced its holdings in the streaming device company Roku Inc (NASDAQ:ROKU), offloading 50,823 shares for a total of nearly $4.5 million through its ARKK ETF. This move comes after a previous sale of Roku shares on Tuesday, July 8th, indicating a possible strategic shift away from the company.

Additionally, ARK sold 56,503 shares of the digital payments company Block Inc (NYSE:XYZ), formerly known as Square, valued at over $6.5 million. This divestment is part of a broader sell-off of Block shares by the fund, suggesting a reassessment of its position in the fintech space.

In the healthcare sector, ARK also parted with 5,627 shares of Veeva Systems Inc (NYSE:VEEV), a cloud-computing company focused on pharmaceutical and life sciences industry applications, for a total value of approximately $1.6 million through its ARKG ETF.

The trades from the past week show a pattern of selective buying and selling across ARK’s ETFs. Notably, there has been a consistent accumulation of shares in Beam Therapeutics Inc (NASDAQ:BEAM) and a recurring investment in Compass Pathways PLC (NASDAQ:CMPS), indicating a bullish stance on these biotech firms. Conversely, the repeated selling of shares in 908 Devices Inc (NASDAQ:MASS) and Roblox Corp (pre-reincorporation) (NYSE:RBLX) suggests a bearish outlook or a portfolio rebalancing effort.

Investors closely watch ARK’s trading activity, led by Cathie Wood, for insights into the fund’s strategy and outlook on various sectors, especially given ARK’s focus on disruptive innovation. Today’s trades underscore ARK’s dynamic approach to managing its ETF portfolios, reflecting ongoing adjustments in response to market conditions and company performance.
