The investigation centers on allegations of violations of the Monopoly Regulation and Fair Trade Act through the abuse of its dominant market position, according to regulatory filings.
The KFTC’s move follows a months-long review of Google’s business practices, which the commission claims have stifled competition in South Korea’s digital economy. A spokesperson for the KFTC confirmed the enforcement process has begun, stating, “We are conducting a thorough investigation into allegations of market dominance abuse, in accordance with our legal mandate to ensure fair competition.”

If found guilty, Google could face penalties up to the maximum allowed under South Korea’s antitrust laws. This figure aligns with the KFTC’s previous largest fine— a previous large fine imposed on Samsung in 2021 for collusion in the memory chip market.
However, the case faces legal challenges due to the precedent set by the 2022 Supreme Court ruling in the “Kakao vs. Google
