Coupang may avoid direct liability for a data breach affecting over 33 million users, but it could still face accountability for alleged fiduciary failures, an attorney said.

New York-based investor rights law firm Rosen Law Firm on December 18, 2025 filed a class-action lawsuit against Coupang in the US District Court for the Northern District of California on behalf of the company’s investors.

The lawsuit alleges that Coupang’s stock price declines and investor losses resulted from failures in corporate disclosures, financial reporting, or internal controls.

Coupang’s market capitalization dropped from US$53.3 billion to US$42.4 billion during the period in question.

The lawsuit is open to investors worldwide who purchased Coupang shares in that timeframe, regardless of realized losses or residency.
