The ranking
Seoul ranks third overall in the 2026 AI Cities Index and first in the category dedicated to the adoption and use of artificial intelligence. This is reported by the Seoul Metropolitan Government, cited by the Korea Herald, stating that the index was published by The Observer. Ahead of the South Korean capital are the San Francisco Bay Area, in first place, and New York; Seoul ranks ahead of Beijing, Paris and London.
The index assessed 57 cities in 36 countries, structuring the comparison across three categories — investment, innovation, and adoption and use — and 50 indicators; the methodology combines quantitative data and qualitative field research. The most significant finding for Seoul is its first place in the third category, which measures the extent to which infrastructure, institutions and systems support AI applications in businesses, public administrations, schools and communities.
The factors cited
According to the report, The Observer explained the result by citing Seoul's support for small and medium-sized enterprises through the AI Innovation Committee and the strength of the semiconductor industry, led by Samsung Electronics and SK hynix. These are elements cited by the index, not an independent assessment produced by the news source.
The third place overall and the first place in adoption reflect two distinct aspects: the overall position summarizes the three categories, while the lead in adoption specifically concerns the ability to translate tools and infrastructure into concrete uses. The material does not indicate the scores Seoul obtained in individual categories or the gap from nearby cities in the ranking, so it is not possible to determine how much the third place depends on adoption compared with investment and innovation.
What remains to be verified
The material does not clarify several elements useful for framing the result: it does not state the exact number of cities included in the adoption category, does not specify the individual indicators that weighed most heavily, and does not clarify whether the index is published annually or how positions have changed compared with previous editions. It also does not detail the boundaries of the San Francisco Bay Area, which appears in the ranking as a territorial entity broader than a single city.
The news has a limited but measurable impact: it places Seoul in a leading position on an issue — the ability to put AI at the service of businesses and public services — that other cities in the same index are pursuing. The statements on support for SMEs and on the role of semiconductors should be attributed to The Observer and the Seoul Metropolitan Government; any assessment of the effectiveness of such policies would require data not present in the source.
