On June 11, Coupang rose 5.16% in pre-market trading, trading at approximately $15.86/share, with trading volume of $420,200.

On the news front, South Korea's Personal Information Protection Commission officially imposed a record 624.7 billion won (approximately $409 million) fine on Coupang for a major data breach affecting nearly 34 million user accounts and non-consensual data collection. Of the total penalty, 423.6 billion won was attributed to the data leak itself, while 201.1 billion won was for illegally collecting personal information. The commission cited weak internal controls that allowed a former employee to access customer data undetected for months.

Crucially, the actual fine came in significantly below the previously feared maximum of 1.5 trillion won, representing only approximately 1.4% of revenue — well under the statutory ceiling. With the stock already down roughly 35% year-to-date amid regulatory uncertainty, the resolution of the penalty at the lower end of expectations triggered a relief rally. Coupang stated it regretted the ruling and would review the formal decision, retaining the option to challenge the penalty in court. The company had previously warned that customer compensation measures tied to the breach could slow revenue growth this year, and reported a $242 million operating loss in the first quarter.
