A securities class action lawsuit was filed against Trip.com Group (NASDAQ: TCOM) after the company’s shares plunged 17 percent following its disclosure of an anti-monopoly investigation by Chinese regulators.
"We're investigating whether Trip.com may have misled investors about the true purpose of its AI pricing tool and the sustainability of its business model without it," said Reed Kathrein, the Hagens Berman partner leading the firm's investigation.
The lawsuit follows a January 14, 2026, announcement that China's State of Administration for Market Regulations had commenced an investigation into the company. The news sent Trip.com’s American Depositary Shares down $12.90 to close at $62.10, erasing over $8 billion in market capitalization in a single trading day. The class period for the lawsuit covers investors who purchased securities between April 30, 2024, and January 13, 2026.
At the center of the probe is Trip.com’s automated AI price adjustment tool. The complaint alleges the company, which had previously called the AI tool "a cornerstone of our long-term strategy," failed to disclose the significant regulatory risks it posed. Reports from late 2025 indicated that hotel partners felt they were losing pricing autonomy and that the tool enabled Trip.com to force participation in promotions and penalize non-compliant merchants.
The company later announced on March 8, 2026, that it would shut down the AI-powered tool. The move followed the abrupt resignation of its co-founders from the board in late February.
The lawsuit creates significant uncertainty for China’s largest online travel agency, which now faces potential financial liabilities and reputational damage. Investors will be watching for developments in the regulatory investigation and the class action case, with the next key date being the May 11, 2026, deadline for lead plaintiff applications.
