Trip.com Faces Securities Class Action as AI Pricing Controversy Drags On

A US law firm filed a securities class action against Trip.com Group last week, the latest legal consequence of the company's controversial AI-powered hotel pricing tool and the Chinese antitrust probe it triggered.

The lawsuit, brought by Hagens Berman Sobol Shapiro, seeks to represent investors who held Trip.com American Depositary Shares between April 30, 2024 and January 13, 2026. It alleges the company misled shareholders by understating the regulatory risk tied to its AI price adjustment tool — a system Trip.com had publicly described as "a cornerstone of our long-term strategy."

What the tool actually did

The AI pricing tool automatically scanned competitor rates and lowered hotel prices on Trip.com's platform to match them. Trip.com presented this as a benefit to consumers and a competitive differentiator. Hotel partners saw it differently.

Multiple hotel operators reported that the system cut their listed rates without their approval, eroding revenue and creating conflicts with rates they had set on other channels. Some described the practice as coercive — those who resisted saw reduced visibility on the platform. The complaint cites reports from late 2025 in which hotel merchants said they had effectively lost control over their own pricing while listed on Trip.com.

That framing matches what Chinese regulators concluded. In January 2026, Trip.com disclosed it had received a formal notice of investigation from China's State Administration for Market Regulation (SAMR) under the country's Anti-Monopoly Law. The stock fell 17% — roughly $8 billion in market capitalisation wiped out in a single day.

The fallout since January

Trip.com said it would cooperate with the SAMR investigation and that its operations remained normal. But the months that followed brought further disruption. In late February, both co-founders resigned from the board with no explanation given. In March, the company shut down the AI pricing tool entirely, announcing it was doing so to "restore pricing autonomy for hotel partners."

That phrase is doing a lot of work. Removing the tool was an admission, in practical terms, that the system had been taking pricing autonomy away in the first place.

The securities class action filed on May 6 argues that investors were never given an accurate picture of the regulatory exposure this created. The lead plaintiff deadline is May 11.

What it means for operators

For hotel and property managers active on Trip.com — particularly those in the Asia-Pacific market, where the platform commands significant share — the episode is a useful reference point. The Trip.com case shows concretely how AI-driven pricing tools can operate at a scale and speed that bypasses a property's own rate decisions, especially when the platform has the leverage to penalise non-compliance through reduced search visibility.

The SAMR investigation remains open. Trip.com has not commented publicly on the class action. Any outcome there will take time, but the sequence of events — probe, co-founder exits, tool shutdown, lawsuit — suggests the consequences of the original pricing strategy are far from settled.
