The United States confirmed in May 2026 and moved fast: the State Department has already appointed Vita Motus to design the USA Pavilion and Trivandi USA to run operations, with a focus on American leadership in sports and music.

The United States formally confirmed its participation in May 2026, when Serbian President Aleksandar Vučić and U.S. Under Secretary of State for Public Diplomacy Sarah Rogers signed a bilateral participation agreement in Belgrade — making the US one of the later big confirmations, pushing the participant count past 137.
Weeks later, the State Department announced its delivery team: design studio Vita Motus leads the design of the USA Pavilion, and Trivandi USA leads operations and delivery. Trivandi comes directly from running operations for the USA Pavilion at Expo 2025 Osaka — which welcomed more than 1.8 million visitors — and is appointed for both Expo 2027 Belgrade and Expo 2030 Riyadh.
Per the State Department, the pavilion will demonstrate American leadership and excellence in sports and music, and position the United States as a premier economic partner in the Balkans and globally. Trivandi describes the Belgrade pavilion as focused on sport and entertainment, "celebrating the United States' global leadership in those industries".
National pavilions sit in the International Participant Area of the 25-hectare Expo site at Surčin, in the western part of Belgrade — the zone that becomes the city's new Belgrade Fair after the event. The site is about 5 km from Nikola Tesla Airport and roughly 13.5 km southwest of central Belgrade (official planning figures), so if you fly in, you land closer to the Expo grounds than to town. Exact positions within the zones haven't been published yet; we'll add the location when the site plan lands.
