South Korea fines Google, Apple 63.7 billion won over in-app payments

The decision by South Korean authorities to levy a combined penalty of 63.7 billion won against Google and Apple concerning in-app payment mandates could establish a significant precedent for how global application marketplaces operate, potentially altering the balance of power between developers and platforms internationally.

The Korea Media and Communications Commission (KMCC), which serves as the country's telecommunications and media regulator, finalized the fines on October 28, 2026. These penalties conclude an inquiry that commenced in August 2022, focusing on regulations that required developers to utilize the technology giants' proprietary payment infrastructures.

The primary contention revolves around the accusation that both corporations coerced developers into utilizing their specific payment mechanisms instead of allowing them to freely select other options. The investigation determined that both entities imposed effective charges of approximately 26% on payment methods originating from third parties, a rate that contrasts with the 30% standard previously established by the platforms.

The legal basis for this action stems from an amendment to South Korea's Telecommunications Business Act enacted in 2021, which became effective in March 2022. Regulators initiated their examination in August 2022, only a few months after these new rules were put into effect. A preliminary notice of sanctions was issued in October 2023, but the matter subsequently faced procedural delays spanning almost three years.

A significant element contributing to the protracted timeline involved discussions regarding the nature of necessary corrective measures, extending beyond merely imposing a financial penalty. The most complex aspect involved issues termed "anti-steering" obligations, which address whether platforms are permitted to prevent developers from directing users toward less expensive payment alternatives situated outside the application environment.

The investigation specifically highlighted that these payment stipulations and the roughly 26% fee applied to third-party transactions placed local developers at a distinct disadvantage. The research findings suggest that this ruling might extend its influence beyond the borders of South Korea, potentially impacting how international platforms manage payment systems and market competition within app marketplaces.

Regarding the financial breakdown, Google is responsible for the larger portion of the fine, amounting to roughly 42.9 billion won, while Apple's share is calculated to be about 20.8 billion won; it is worth noting that these figures have experienced changes since regulators initially presented them in October 2023, when the preliminary figures were cited as 47.5 billion won for Google and 20.5 billion won for Apple.

The 26% fee figure is anticipated to attract considerable attention from observers, as it implies that merely allowing alternative payment methods does not automatically guarantee robust competition if platforms retain the ability to charge commissions near the established standard for external transactions.

This regulatory action underscores a growing global trend where governmental bodies are increasingly scrutinizing the economic structures of dominant digital platforms, particularly concerning payment processing and market fairness for smaller participants.

Why it matters

This regulatory action from South Korea directly impacts the operational dynamics between app developers and major platform holders. Such rulings could signal increased scrutiny globally regarding how digital marketplaces enforce payment structures. Readers should watch how other jurisdictions respond to this precedent-setting fine.
