Baidu (BIDU) Shareholders Sue Company Over AI Business Growth Claims

A class action lawsuit was filed against Chinese tech group Baidu (BIDU) on September 14, 2026. Plaintiffs in the federal securities lawsuit allege that they acquired Baidu American Depositary Shares ("ADS") at artificially inflated prices between November 18, 2025 and August 17, 2026, known as the Class Period. They are now seeking compensation for financial losses incurred upon public revelation of the company's alleged misconduct during that time.

What Does BIDU Do?

Baidu is a Chinese technology company that operates the most popular internet search engine in China. Its core legacy business is Online Marketing Services, which represented approximately 53.1% of total revenues for the third quarter of 2025. Baidu is incorporated in the Cayman Islands with principal executive offices in Beijing, and its American Depositary Shares trade on the NASDAQ under the symbol BIDU, with each ADS representing eight Class A ordinary shares.

Why are Shareholders Suing BIDU?

The complaint centers on Baidu's public messaging about its transition from a declining legacy advertising business to a new AI-powered business. Online Marketing Services, Baidu's core legacy business, had been falling steeply, dropping 17.6% year over year in the third quarter of 2025 on a consolidated basis.

The complaint alleges that Baidu made materially false and misleading statements about its business. It claims the company overstated how much its new AI-powered business could offset the falling legacy online marketing revenue. According to the complaint, Baidu overstated the ability of its AI business to mitigate the legacy decline, while the company's revenue was reasonably likely to fall.

When the alleged problems surfaced, Baidu's stock price fell sharply. On February 26, 2026, the ADS dropped 5.65% after fourth quarter results. On August 18, 2026, the ADS fell 12.73% after weaker second quarter results, leaving investors with significant losses.

Baidu's share price is down 43% in the year to date – see below:

The complaint names three defendants: Baidu, Inc., Robin Yanhong Li, and Haijian He. According to the complaint, Robin Yanhong Li served as the company's Chief Executive Officer at all relevant times, and Haijian He served as Chief Financial Officer at all relevant times. The lawsuit alleges that these Individual Defendants, because of their positions, controlled the contents of the company's SEC reports, press releases, and presentations, and had the ability to prevent or correct statements alleged to be materially false and misleading.

The deadline to file for lead plaintiff in this securities lawsuit is November 13, 2026.
