Coupang’s shares slipped by 1.17% in the latest trading session, underperforming major U.S. indices which advanced by more than 0.5%. This marks the third consecutive day of declines for the South Korean e-commerce giant, narrowing its year-to-date gain to roughly 12%. Trading volume was approximately 15% above the 30-day average, suggesting elevated selling pressure as investors digest weaker domestic consumption figures and heightened competition from regional rivals.

On January 20, 2026, national plaintiffs’ firm Berger Montague PC initiated a class action suit against Coupang on behalf of investors who purchased securities between May 7 and December 16, 2025. The complaint alleges that insufficient cybersecurity protocols allowed a former employee to access sensitive customer information for nearly six months without detection. In the wake of the breach, Coupang’s chief executive announced his resignation and the stock experienced material losses. Affected investors have until February 17, 2026 to petition for lead-plaintiff status and may contact the firm’s representatives for further details.
