International Mathematical Olympiad 2025 Concludes in Australia

The 66th International Mathematical Olympiad (IMO) concluded on July 20, 2025, in Sunshine Coast, Queensland, Australia. This prestigious event brought together 641 students from 112 countries, marking the second time Australia has hosted the IMO since 1988. The competition featured two days of rigorous examinations, with nine hours of testing in total. The closing ceremony celebrated the students' achievements, including the awarding of medals and a Great Australian barbecue. Notably, the AI Mathematical Olympiad Prize was introduced this year, a $10 million competition aimed at encouraging the creation of open-source AI models. The IMO also hosted a fringe event where AI companies presented their latest developments to students and privately tested closed-source AI models on this year's problems. The IMO emphasized that while AI models are advancing in mathematical problem-solving, the organization cannot validate the methods used or the reproducibility of results. The event underscored the importance of correct mathematical proofs, regardless of whether they are produced by human contestants or AI models.
