Robbins Geller Rudman & Dowd LLP has announced a class action lawsuit against Trip.com Group Limited (NASDAQ: TCOM) on behalf of investors who purchased or acquired the company's publicly traded securities between April 30, 2024 and January 13, 2026. The lawsuit alleges that Trip.com and its executives recklessly understated the regulatory risk facing the company due to its monopolistic business activities.

Why it matters

The antitrust probe by Chinese regulators into Trip.com's alleged unfair practices could have significant implications for the company's future, including potential fines, restrictions on its business, and reputational damage. This case highlights the growing scrutiny of large tech companies' market dominance and the risks they face from regulatory crackdowns.

The details

The class action lawsuit alleges that Trip.com made false and/or misleading statements and failed to disclose that the company was facing significant regulatory risk due to its monopolistic business activities. On January 14, 2026, Bloomberg reported that China had launched an antitrust investigation into Trip.com, with the market regulator in Zhengzhou previously summoning the company for violations of rules against setting 'unfair restrictions' on merchants' transactions and prices. This news caused the price of Trip.com's American Depositary Shares to fall approximately 19% over two trading sessions.
