Coupang Gains 1.91% Even After 1.55M Penalty, With 57.11% Volume Jump to 510M, Placing 267th Under Regulatory Review

Market Overview

On February 26, 2026, Coupang (CPNG) saw its share price climb by 1.91%, even as South Korea’s antitrust authority levied a $1.55 million penalty against the company. Trading activity was robust, with volume jumping 57.11% to $510 million, placing Coupang 267th in daily market turnover. Despite the regulatory setback, the stock’s positive movement suggests that investors remain confident, showing resilience in the face of ongoing operational and regulatory hurdles.

Main Factors Influencing Performance

The Korea Fair Trade Commission (KFTC) sanctioned Coupang for breaching large-scale retail business regulations. The company was found to have pressured its suppliers to lower prices and absorb additional costs to help Coupang meet its profit objectives. Under the “Coupang Experience Group” initiative, vendors were required to pay for advertising and data services, and those who resisted faced threats of reduced or halted orders. The KFTC described these actions as retaliatory and anti-competitive, pointing to deeper issues in Coupang’s supplier management. The regulator also noted that Coupang’s dominant position in the market enabled it to exert undue influence over smaller partners, raising questions about the long-term viability of its business practices.

Beyond the fine, Coupang also came under fire for delaying payments to suppliers in over 508,000 transactions between October 2021 and June 2024. These late payments totaled 281 billion won (approximately $197 million), further straining relationships with vendors and highlighting operational weaknesses. Such delays risk undermining supplier trust and could destabilize the supply chain, especially in the fast-paced e-commerce sector where prompt fulfillment is essential. The KFTC has now ordered Coupang to overhaul its margin management and supplier engagement policies, which may lead to higher short-term costs as the company adapts to meet regulatory requirements.

This regulatory scrutiny comes as Coupang faces mounting competition from both traditional retailers and digital rivals. The South Korean government is also pushing for reforms to foster greater competition in e-commerce, including new rules that allow physical stores to offer overnight delivery—a move that could erode Coupang’s “Rocket Delivery” edge. These shifts signal a changing competitive landscape, making it crucial for Coupang to balance compliance with continued innovation. Investors are watching closely for the company’s fourth-quarter earnings report, released on the same day as the fine, to gauge its financial strength and strategic response to these challenges.

While the stock’s 1.91% rise on the day of the fine stands out, it contrasts with Coupang’s longer-term difficulties. A data breach last year, which allegedly impacted 33.6 million users (a figure Coupang disputes), triggered a 35% drop in share price. The recent fine adds to regulatory headwinds, but the modest price increase may indicate investor optimism about Coupang’s ability to weather adversity or confidence in its growth prospects. However, the company’s operating margin shrank to 0.1% in the fourth quarter of 2025, down from 3.9% a year earlier, reflecting pressure from competitive pricing and regulatory changes. Analysts anticipate 14.4% revenue growth over the next year, but this outlook must be balanced against the costs and reputational risks of ongoing compliance efforts.

In conclusion, Coupang’s recent market performance highlights the complex interplay of regulatory challenges, supplier relations, and competitive pressures. The company’s scale and leadership remain strengths, but its future success will depend on how effectively it adapts to regulatory reforms and maintains profitability. With investors weighing short-term resilience against long-term risks, the upcoming earnings report will be a key indicator of Coupang’s strategic direction.
