Baidu, Inc. et al., was filed on September 14, 2026 in the U.S. District Court for the Southern District of New York (Case No. 26-cv-08012).

What happened?

On February 26, 2026, before the market opened, the Company reported fourth quarter and full year 2025 financial results, revealing that total revenue fell more than 4% year over year for the fourth quarter to RMB32.74 billion (or $4.68 billion) and fell more than 3% year over year for the full year to RMB129.079 billion (or $18.458 billion). However, Baidu management assured investors its "AI-Powered Business" grew 48% year over year to RMB40 billion for fiscal year 2025, mitigating this transition.

On this news, the price of Baidu American Depositary Shares ("ADS") fell $7.50 per share or 5.65%, to close at $125.15 per share on February 26, 2026, on unusually heavy trading volume.

Then on August 18, 2026, before the market opened, the Company reported second quarter 2026 financial results, revealing that Baidu General Business revenue fell 4% year over year to RMB25.2 billion (or $3.71 billion), with Legacy Business revenue falling 23% year over year to RMB10.4 billion and total Online Marketing Services revenue falling 19% year over year to RMB13.1 billion. Critically, the Baidu Core AI-powered business fell 8% quarter over quarter to RMB12.5 billion (or $1.86 billion), its year-over-year growth having decelerated from 49% in the first quarter of 2026 to 25%, and its largest component, AI Cloud Infra, having fallen 17% quarter over quarter from RMB8.8 billion to RMB7.3 billion.

On this news, the price of Baidu ADS fell $13.25 per share, or 12.73%, to close at $90.87 on August 18, 2026, thereby further injuring investors.

What is the Baidu, Inc. lawsuit about?

The Baidu, Inc. securities lawsuit alleges that, between November 18, 2025 and August 17, 2026, defendants made materially false and/or misleading statements and failed to disclose material adverse facts about Baidu, Inc.'s business, operations, and prospects. Specifically, the complaint alleges defendants failed to disclose that: (1) the Company had overstated the ability of its AI business to mitigate rapid declines in its legacy online marketing business; (2) as a result, the Company's revenue was reasonably likely to decline; and (3) as a result, defendants' positive statements about Baidu, Inc.'s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

"The complaint filed against Baidu, Inc. alleges that, among other things, the Company failed to disclose that the Company had overstated the ability of its AI business to mitigate rapid declines in its legacy online marketing business. For investors who bought during the class period, the November 13, 2026 deadline is the first major step in this case," said Charles H. Linehan, Partner at Glancy Prongay Wolke & Rotter LLP.
