China's State Administration for Market Regulation (SAMR) has slapped a 5.2 billion yuan (US$765 million) antitrust penalty on Trip.com Group, the country's largest online travel services provider, after finding the company had abused its dominant market position — marking one of the most significant regulatory actions against a Chinese internet platform in recent years.

What the regulator found

The SAMR announced on Saturday, 25 July 2026 that Trip.com had engaged in anticompetitive practices dating back to 2020, leveraging its traffic-allocation algorithms, platform rules, and technology to entrench its dominance. Specifically, the regulator found that the company forced certain hotel partners into exclusive arrangements and required some of them to offer their lowest available online rates exclusively on its platform.

The penalty comprises two components: a confiscation of 1.658 billion yuan in illegal gains and an additional fine of 3.521 billion yuan — equivalent to 7.5 per cent of the company's domestic sales of 46.958 billion yuan recorded in 2025.

Trip.com's sprawling platform empire

Trip.com Group operates a portfolio of travel brands that spans both domestic and international markets. Its holdings include the internationally focused Trip.com platform, China-centric booking sites Ctrip and Qunar, and the globally recognised flight-search engine Skyscanner. The breadth of this ecosystem gave the company the market leverage that regulators ultimately found to be anticompetitive.

The company did not immediately respond to a request for comment on the day of the announcement.

Market reaction

Trip.com's Hong Kong-listed shares fell 0.8 per cent to HK$342.60 (US$43.69) on Friday, ahead of the formal announcement — suggesting markets had already begun pricing in regulatory risk. The stock has lost significant ground from a peak of over HK$600 at the start of 2026, a decline that reflects both the overhang of the investigation and broader pressure on Chinese tech valuations.

The competitive backdrop

The action against Trip.com follows a broader pattern of SAMR enforcement against dominant internet platforms in China. Alibaba Group Holding was hit with a record 18.2 billion yuan fine in 2021 for similar 'choose one of two' exclusivity practices, and food-delivery giant Meituan faced a 3.44 billion yuan penalty the same year. The travel sector, long seen as a regulatory blind spot, has now clearly entered the crosshairs.

Rival platforms including MakeMyTrip and domestic competitors may find the ruling opens space for renegotiating hotel partnerships that were previously locked into Trip.com's ecosystem.

What's next

The scale of the fine — and the six-month investigation that preceded it — signals that SAMR is prepared to sustain enforcement pressure on platform economies beyond e-commerce and food delivery. Investors and hotel partners alike will be watching whether Trip.com contests the ruling, restructures its partner agreements, or absorbs the penalty as a cost of doing business in an increasingly regulated domestic market.
