With three weeks to go to the start of IMO 2026 in China, we are delighted to announce that 685 contestants from 119 countries will be travelling to Shanghai to compete in the annual prestigious mathematical competition for young adults.
This is the greatest number of competitors at the annual Mathematical Olympiad and the largest number of countries to send participants.
We also welcome observers from four countries (Bermuda, Ethiopia, Kuwait and Lebanon) who are in attendance to understand the requirements to send a national team to the IMO, and we look forward to these new countries sending participants in the near future.
