Expo 2027 participant tracker

Who is coming to Expo 2027 Belgrade, in numbers: the official participant count, every country a source has publicly named, and how the total has grown — independently tracked and sourced.

141
international participants (organiser, Aug 2026)
93
countries publicly named so far
5
continents represented among named countries
№1
largest Specialised Expo by participants — Astana 2017's record fell in July 2025
Read the two numbers honestly. The organiser's own August 2026 figure is 141 international participants — the official Participants page counter last read 139 and names only a subset. Our table lists the 93 countries a source has actually named — absence from it does not mean absence from the Expo. Background: who's coming to Expo 2027.
