Google’s share of South Korea’s search market has overtaken local champion Naver for the first time, according to Aju Press, a first in a market long considered the toughest test of whether foreign platforms can break into Asian internet services.
The change is driven by AI, the report said, with Google’s Gemini-powered search experience pulling users away from a homegrown rival that dominated the country for two decades. Korea is one of the most competitive search markets in the world: Naver built its lead by localizing everything, from Korean-language results to payment services, webtoons, shopping and a community ecosystem that Google could not easily replicate. For years the local player held more than half of the market, and Google was stuck in a distant second place, its global scale useless against a competitor that understood Korean internet habits better than any foreign company could.
AI has changed the math. Google’s search results now carry generative summaries, conversational follow-ups and integrated answers, features that have made the product feel qualitatively different from the classic list of blue links. Korean users, heavy adopters of new technology, have been among the fastest to switch, according to the report, and the migration has accelerated in recent months as Google pushed Gemini features into more markets. For Naver, the reversal is an alarm: its own AI efforts, including an in-house large language model and AI shopping tools, have not yet produced a product that matches the polish of Google’s integrated experience.
The shift carries significance beyond Korea. It is the first time AI-powered search has broken through a localization barrier in a major non-English market, and strategists at both companies will read the result as a template for other countries where local champions have held off global platforms. Japan’s Yahoo Japan, Russia’s Yandex and China’s Baidu all built their dominance on local content and local context, and each is now facing the same question: can a generational change in the product, not a change in localization strategy, crack a market that was thought to be sealed?
For Naver, the response is likely to be a mix of defense and adaptation. The company has long argued that its strength is not search itself but the ecosystem around it, shopping, payments, content, communities, and it will try to keep users inside that ecosystem even if they search elsewhere. It is also investing in its own AI, including an assistant tied to its services, and in deepening the local content that Google cannot easily reproduce. Analysts said the question is whether ecosystem loyalty survives a better search box. “Korean users like Naver, but they use Google when Google is better,” one analyst said. “That sentence is new, and it is the whole problem.”
For Google, the Korean result is a rare piece of good news in a global search business under pressure. Regulators in the U.S. and Europe have spent years attacking the company’s search monopoly, and AI products from OpenAI and others now threaten the core service from a different direction. Winning a market that was once considered unwinnable provides evidence that AI features can convert users, and Google will deploy that evidence in its pitch to advertisers, partners and regulators alike. The company has also been pushing Gemini into other non-English markets, including Japan and Southeast Asia, where similar local champions dominate.
The stakes for Korean users are subtle but real. Naver’s decline would concentrate more of the country’s search, advertising and data flows in the hands of a U.S. company, a shift that Korean regulators, who have a history of aggressive enforcement against foreign platforms, will watch closely. Google has already faced fines and pressure in Korea over app-store practices and advertising rules, and a search victory may invite a new round of scrutiny rather than gratitude.
The market share data itself is contested terrain. Naver disputes the most common measurement, which counts desktop and mobile search queries, arguing that a large share of Korean internet activity happens inside apps and closed services where search is a feature rather than a destination. By that broader definition, Naver argues, its influence remains dominant. Google and its measurement partners counter that the query-based numbers capture intent, the activity advertisers actually pay for, and that app-internal search cannot be monetized the same way. The argument matters because ad budgets follow whichever definition wins, and Korean advertisers have already begun shifting spending toward Google, according to people in the local digital-ad market.
For now, the numbers tell the story. Google’s share passed Naver’s in a market that was supposed to be impenetrable, and the engine of the change was not localization but AI. The question both companies now face is whether the shift is a blip or the start of a permanent reordering, and the answer will shape how every search company in the world thinks about its AI spending.
