Cathie Wood’s ARK Invest executed major portfolio changes on September 30, 2025. The investment firm bought millions in Chinese technology stocks while selling other positions.
The ARK Innovation ETF acquired 52,388 Baidu shares. The purchase totaled approximately $7.1 million. This was the fund’s largest single transaction of the day.

Wood’s team also bought 23,538 Alibaba shares worth $4.2 million. This purchase continues a pattern from earlier trading days. The ARK Space Exploration ETF added 263,700 JD Logistics shares valued at $441,202.
Why ARK Is Buying Chinese Tech Stocks
The Chinese technology purchases follow recent industry developments. Both Baidu and Alibaba have advanced their artificial intelligence capabilities. The companies now use proprietary AI chips for model training.
This shift reduces their reliance on Nvidia chips. Alibaba recently launched a high-performance processor targeting the Chinese AI chip market. These developments appear to be driving ARK’s increased interest in the sector.
The fund has been building positions in Chinese tech companies over multiple trading sessions. The consistent buying pattern suggests long-term conviction in these investments.
ARK Exits Brera Holdings Position
ARK Innovation ETF sold 231,903 Brera Holdings shares for $7.05 million. This represents a major position reduction. The timing is interesting given previous investments in the company.
The fund had invested $49 million in Brera Holdings during its Solmate transformation. Wood added another $162 million to the position just one week earlier. The recent sale marks a quick reversal in strategy.
Brera stock experienced volatile trading on September 30. Shares jumped 14.9% during intraday trading before closing down 1.3%.
Defense and Biotech Adjustments
The ARK Space ETF sold 16,048 Kratos Defense shares worth $1.4 million. This continues a multi-day trend of reducing the defense contractor position. The sales appear part of broader portfolio rebalancing.
In the biotech sector, ARK maintained certain convictions. The Innovation and Genomic Revolution ETFs purchased 98,814 Intellia Therapeutics shares. The combined investment exceeded $1.6 million across multiple trading sessions.
The Space ETF made a smaller purchase of 2,147 Thales SA shares for $664,163. This fits ARK’s strategy of investing in innovative companies.
Analyst Ratings on ARK Holdings
Wall Street analysts rate Alibaba as a “Strong Buy.” Kratos Defense also carries a “Strong Buy” consensus rating. Alibaba stock shows higher upside potential according to analyst price targets.
