- The class period is November 18, 2025 to August 17, 2026.
- The lead plaintiff deadline is November 13, 2026.
- The complaint alleges Baidu overstated the ability of its AI business to offset the decline in its legacy marketing business.

What the lawsuit alleges
According to the press release from Schall, Brown & Schwartz LLP (SBS), the class action accuses Baidu, Inc. of violating Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5, which was promulgated under the Act by the U.S. Securities and Exchange Commission.
The core claim concerns Baidu's public statements. According to the complaint as described by SBS, the company made false and misleading statements to the market. It allegedly overstated the ability of its AI business to cover the rapid decline in its legacy marketing business. The complaint also states that the company was likely to suffer a decline in revenue.
On that basis, the complaint argues that Baidu's public statements were false and materially misleading throughout the class period. SBS says investors suffered damages when the market learned the truth about the company. These are allegations made in the complaint and in the law firm's announcement, not findings by a court.
Class period and deadline
The class period runs from November 18, 2025 to August 17, 2026. Shareholders who purchased BIDU shares during that window are encouraged by SBS to contact the firm about possible lead plaintiff appointments.
The deadline listed in the release is November 13, 2026. SBS also states that appointment as lead plaintiff is not required to take part in any recovery.
- Company: Baidu, Inc. (NASDAQ: BIDU)

Status of the case and what shareholders can do
SBS notes that the class has not yet been certified. Until certification occurs, it says, shareholders are not represented by an attorney. Investors who take no action can remain absent class members.
The firm invites affected shareholders to contact Brian Schall or David Schwartz at its Los Angeles office, 2049 Century Park East, Suite 2460, by phone at 310-301-3335, or through its website, www.schallfirm.com. SBS says the discussion of rights is free of charge.
SBS describes itself as a national shareholder rights litigation firm that represents investors around the world and specializes in securities class action lawsuits. It names founding partners Brian Schall, Andrew Brown and David Schwartz. The release carries a notice that it may be considered attorney advertising in some jurisdictions.
What it means for investors
The case centers on a question many investors in large technology companies face: whether AI growth can make up for weakness in older revenue streams. The complaint alleges that Baidu's statements on this point were misleading. The source does not describe Baidu's response, any court ruling or any financial figures, so the outcome remains open.
Shareholders who bought during the class period and believe they suffered a loss can contact the firm before the November 13, 2026 deadline if they wish to seek a lead plaintiff role. Those who do nothing may remain absent class members.
