South Korea has emerged as a core revenue market for global generative AI companies. After OpenAI's ChatGPT and Google's Gemini built up the domestic paid subscription market, Anthropic's Claude has also rapidly grown its sales in the country. South Korea now ranks second in the world by revenue share for major global AI platforms — a result of Korean users willingly paying around 30,000 won (about $20) a month for AI subscriptions. Global AI firms are intensifying their push into the Korean market in response.
From Jan. 1 through June 5 this year, Claude ranked first in revenue growth among generative AI apps on the South Korean iOS market, according to global market intelligence firm Sensor Tower.
Over the same period, Claude also ranked second in overall revenue, trailing only ChatGPT.
Sensor Tower said Claude's revenue growth likely reflects existing users upgrading to paid plans or moving to higher tiers rather than a surge in new downloads. "It signals that more users are moving beyond simply trying out generative AI and are now paying for it to improve their actual work and productivity," the firm said.
The growth trend is also reflected in country-level revenue breakdowns. During the same period, South Korea accounted for 4.7 percent of Claude's total global revenue — second only to the United States at 41.1 percent. Given South Korea's relatively small population, the figure underscores how actively Korean users are paying for generative AI services.
South Korea's prominence extends to ChatGPT and Gemini as well. The country ranked among the top markets by revenue share for ChatGPT, behind only the United States and Japan. For Gemini, South Korea — at 14.5 percent — was the second-largest revenue market after Japan at 15.0 percent. Across all major generative AI services, South Korea has established itself as a key paid market.
Global AI companies are also accelerating their push into South Korea. OpenAI CEO Sam Altman is set to visit the country again on Saturday to discuss expanded cooperation with major Korean firms including Samsung Electronics, Kakao and Naver. Anthropic, meanwhile, recently opened a local office in South Korea, marking its formal entry into the domestic market.
Industry observers say South Korea has become more than just a user acquisition market for generative AI companies — it is now a key proving ground for paid subscription models. Although its population is smaller than that of the United States or Japan, South Korea's high paid conversion rates and strong workplace adoption make it well suited for testing premium AI subscription services.
Meanwhile, the competitive landscape in South Korea's generative AI market is also shifting. ChatGPT and Gemini have long dominated, but Claude is rapidly closing the gap, creating what is shaping up to be a three-way race. Claude first overtook Gemini in late March and has since widened its lead, with its growth accelerating further in early May.
