AI Summit Barcelona 2026

About this event

AI Summit Barcelona is a large in-person artificial intelligence conference in Barcelona, billed as “Europe’s biggest AI event.” The page highlights 10,000+ expected attendees, 200+ speakers, two full days of programming, and 50+ side events, with content aimed at builders, founders, and decision-makers focused on moving from AI speculation to implementation. It promotes keynotes, tracks, an expo, workshops, experiences, and extensive networking spaces. The site also frames the summit as the centerpiece of “AI Week Barcelona” (16–23 September), which includes a hackathon (19–20 Sep) and partner-run side events across the city.
