Cathie Wood’s ARK Invest executed a substantial transaction on Thursday, February 26, acquiring shares in Chinese technology giant Baidu following a significant stock price decline.
ARK acquired 97,597 shares of Baidu (NASDAQ: BIDU) distributed across its ARKK, ARKQ, and ARKW portfolios. The aggregate investment reached $12.21 million.
The acquisition followed a 5.7% decline in Baidu shares triggered by its Q4 FY2025 earnings announcement. The company surpassed both revenue and profit forecasts, yet investors focused on a 4% year-over-year decrease in overall revenue.
The revenue contraction stemmed from challenges in Baidu’s primary advertising segment, which has faced ongoing headwinds. This decline counterbalanced positive performance in other business units.
ARK seems focused on longer-term prospects beyond the advertising challenges. CEO Robin Li emphasized robust expansion in AI cloud infrastructure alongside increasing enterprise adoption of Baidu’s AI solutions.
During Q4, Baidu’s AI-enabled operations — encompassing cloud infrastructure, AI applications, and autonomous taxi services — generated $1.61 billion. This figure represented 43% of quarterly revenue.
