The Observer released its 2026 AI Cities Index, which evaluated 57 cities across 36 countries and ranked the San Francisco Bay Area first, New York second, and Seoul third. Seoul ranked first in AI adoption and use. The index is an annual-style ranking report already published, not a product or policy in development.
Why it matters
The index scores cities on investment, innovation, and adoption and use, a framing that shifts attention from where AI models are built to where AI is deployed in business, government, education and communities. Seoul's placement, ahead of Beijing, Paris and London, reflects its support for small and medium-sized enterprises through its AI Innovation Committee and its semiconductor base led by Samsung Electronics and SK hynix.
The index draws on 50 indicators spanning investment, innovation, and adoption and use, and it combines quantitative data with qualitative field research. The adoption and use category specifically measures how infrastructure, institutions and systems support AI applications. The stub does not report per-indicator values for Seoul.
The players
The Observer
A publication that produces the AI Cities Index, ranking 57 cities across investment, innovation, and adoption and use.
Samsung Electronics
A South Korean semiconductor and electronics manufacturer whose chip business is a core part of Seoul's technology base.
SK hynix
A South Korean semiconductor company, a major memory chip maker cited as a pillar of Seoul's semiconductor industry.
The details
The index scores each city across three categories: investment, innovation, and adoption and use. The adoption and use category measures how infrastructure, institutions and systems support AI applications across businesses, government, education and communities. Its 50 indicators mix hard quantitative data with qualitative field research, so a city's score reflects both measurable inputs and assessed conditions on the ground.

The Tech Race
The AI Cities Index ranks the San Francisco Bay Area first and New York second overall, placing both ahead of Seoul in overall standing. Seoul's first-place showing in adoption and use suggests competition over AI is shifting partly from model development toward deployment in everyday institutions.
The ranking itself does not change any product or service, but it signals where AI is being built into daily institutions such as businesses, schools and public services. Readers in cities that score well on adoption may see those systems reach them sooner, though the stub gives no timeline for any specific deployment.
The takeaway
Watch whether cities that lead on adoption and use keep their placement as the index is updated in future editions. The next edition will show whether Seoul's adoption lead holds against the Bay Area and New York.
