International Olympiad in Informatics (IOI) 2026 — Tashkent

Uzbekistan hosts the 38th International Olympiad in Informatics (IOI 2026) in Tashkent from 9 to 16 August 2026 — the world's most prestigious competitive-programming contest for secondary-school students, and one of the five major international science olympiads. Scale. IOI 2026 sets a record for the competition's history: 386 contestants from 97 countries, accompanied by around 300 international team leaders, deputy leaders and IOI Committee members, plus representatives of major global IT companies. Venue. The official competition venue is the Central Asian Expo (CAEx) Uzbekistan International Exhibition Center in Tashkent; delegations are accommodated at the New Uzbekistan Hotel Village, with the host committee covering local expenses, full catering and domestic transfers for contestants and leaders from 9 to 16 August. Format. Contestants compete individually over two five-hour competition days, solving algorithmic problems judged automatically. Between competition days the programme includes excursions and cultural events across Tashkent. Why it matters. Uzbekistan becomes only the second Central Asian country to host the IOI, after Kazakhstan in 2015. The national team, which took silver and bronze at IOI 2025 in Bolivia, competes on home ground. Participation is by national delegation only — countries register through the official IOI 2026 host organising committee at ioi2026.uz.
