South Korea Fines Baemin and Coupang Eats Record 631.9 Billion Won Over Pricing Rules

South Korea's food delivery market has become one of the country's most concentrated digital businesses. Baemin, operated by Woowa Brothers, and Coupang Eats, operated by Coupang, accounted for 58.45 percent and 34.44 percent of the market by order value in 2025, according to the Korea Fair Trade Commission. Their combined share of 92.89 percent gave the two apps unusual influence over the terms that restaurants could offer customers. On November 9, 2026, the regulator turned that influence into the largest financial penalty ever imposed on a food delivery app.

The case centers on most-favored-nation requirements, often called MFN clauses. These rules required partner restaurants to give Baemin or Coupang Eats prices and trading terms at least as favorable as those available on competing platforms. For Coupang Eats, the conditions covered six items, including menu prices, minimum order amounts, discounts and delivery charges. Restaurants that failed to comply risked losing a special designation that allowed them to offer discounts and free delivery to the app's paid-membership customers. The commission said the arrangement limited restaurants' ability to set prices independently and made it harder for rival delivery apps to compete.

The Korea Fair Trade Commission imposed provisional penalty surcharges of 331.1 billion won on Woowa Brothers and 300.8 billion won on Coupang, for a combined 631.9 billion won, or about 464 million dollars. The decision covers alleged violations of the Fair Trade Act and the Labeling and Advertising Act. It is provisional, meaning the companies can contest the findings and the amount. Both firms disputed elements of the decision, setting up a legal battle that will shape how South Korea oversees platform pricing rules.

Key Facts

The Korea Fair Trade Commission said on November 9, 2026 that Woowa Brothers would pay 331.1 billion won and Coupang would pay 300.8 billion won. Reuters reported on November 9, 2026 that the Coupang penalty amounted to 220.59 million dollars at an exchange rate of 1,363.6400 won per dollar. The combined total of 631.9 billion won is the largest fine ever imposed on a food delivery app, according to Edaily. The commission described the penalties as provisional surcharges.

Chosun Biz reported on November 9, 2026 that Baemin's penalty was broken down into three parts: 160.2 billion won for demanding most-favored treatment, 155.4 billion won for forcing restaurants to switch from Market Place to in-house Own Delivery, and 15.4 billion won for deceptive advertising about estimated delivery times. Coupang Eats received a single 300.8 billion won penalty for demanding most-favored treatment. The breakdown shows the regulator treated the pricing clause as one part of a broader set of practices.

According to the commission, Coupang enforced its requirements from July 2023 to January 2026. The share of partner restaurants meeting the conditions rose from about 13 percent in July 2023 to nearly 94 percent in October 2025. Yonhap News Agency reported on November 9, 2026 that Coupang stripped restaurants of their Wow restaurant status if they failed to comply with conditions covering menu prices, minimum order amounts and other trading terms. Baemin imposed similar requirements from May 2024 to October 2025 and limited delivery fee discounts for Baemin Club subscribers to compliant restaurants, the agency reported.

Edaily reported on November 9, 2026 that the commission's economic analysis found menu prices rose by 350 won for in-house delivery and by 1,650 won for restaurant delivery on a 25,000 won order. The report also said restaurants excluded from the programs lost 60 to 70 percent of their daily sales. The regulator used those figures to argue that the rules harmed merchants and consumers, not merely shifted costs.

Analysis

The most striking element is the theory of harm, not the headline number alone. The commission did not merely say that two large platforms used aggressive contracts. It said that when companies controlling 92.89 percent of a market impose the same kind of most-favored-nation rule at the same time, the result can resemble collusion even without evidence of a formal agreement. The parallel conduct, in the regulator's view, weakened competition over commission rates and pushed up food prices and minimum order amounts. That is broader than a standard abuse of dominance case and is likely to be tested in court.

What this really means is that South Korea is moving toward treating platform access rules as a form of market-wide pricing regulation. Coupang Eats entered later and charged a higher commission rate, 9.8 percent at the time, than Baemin, according to Edaily. If restaurants could charge more on Coupang Eats to cover that commission, the platform would face pressure to compete on fees. An MFN rule blocks that adjustment by requiring the restaurant to keep its Coupang Eats terms no less favorable than those elsewhere. The commission's economic logic is that this squeezes the main channel through which a higher-cost entrant might compete.

Woowa Brothers offered a different account. It said it introduced the terms as a defensive move after a rival began demanding membership-based most-favored treatment, and it denied coercing merchants or unilaterally changing prices. The company said it had explained that its conduct was not unlawful and regretted that its arguments had not been fully accepted. That defense places the origin of the practice in a competitive response rather than an attempt to suppress competition. The commission rejected that framing, but the dispute highlights how membership programs can become the mechanism through which pricing rules spread across a market.

Coupang's response focuses on proportionality and process. It called the penalty excessive, said the commission had included revenue unrelated to the alleged conduct when calculating the fine, and said it would challenge the decision in court. It also compared the penalty with a 468 million won surcharge imposed on Yogiyo in a past similar case, arguing that an amount more than 600 times higher is clearly discriminatory. The gap is not just about arithmetic. It is about whether a penalty should be anchored to the revenue of the entire company or to the specific business line found to have broken the law.

Why It Matters

The ruling sets a benchmark for how South Korea handles most-favored-nation clauses in digital markets. A 631.9 billion won total is far above earlier penalties in food delivery, and it gives the commission a major precedent for future platform cases. The finding that simultaneous MFN demands can produce effects similar to collusion could influence how the regulator approaches membership-based terms, even if courts may narrow it. For platforms, the practical message is that contract terms used to protect a membership program can be treated as restrictions on competition when the platform controls a large share of the market.

For restaurants, the case is about more than the right to show a different price on a different app. The commission found that excluded restaurants lost 60 to 70 percent of daily sales, according to Edaily, and that menu prices rose on a 25,000 won order. Those numbers explain why the regulator framed the issue as consumer harm as well as merchant harm. If a restaurant cannot set prices independently, it cannot absorb commission differences, test new channels or bargain over terms. The penalty therefore touches the basic commercial freedom of small businesses that rely on delivery platforms for a large share of their orders.

The case also adds to the regulatory pressure on Coupang. The Straits Times reported on November 9, 2026 that South Korea fined Coupang 624 billion won in June 2026 over a 2025 data breach affecting more than 33 million customers. The company has disputed the government's findings, while Republican US lawmakers have accused Seoul of discriminating against an American company, a claim South Korean officials reject. The delivery case is separate from the data breach matter, but together they reinforce the perception that Coupang is operating under unusually close scrutiny in its home market.

Next Up

Coupang has said it will challenge the decision through legal proceedings, so the immediate next phase is a court fight over both the finding and the size of the penalty. The company's argument about unrelated revenue will be central to how the commission calculates fines for platforms with multiple services. Woowa Brothers has said it regrets that its arguments were not fully accepted. The 631.9 billion won total will not be the final word until that process runs its course.

The question is whether the MFN theory travels beyond these two apps. If the courts uphold the commission's view that simultaneous most-favored-nation rules can function like collusion, the case could become the reference point for a wider set of investigations. If the courts narrow it, the regulator will have to build future cases around specific evidence of harm rather than market structure alone.
