Recent reports of Chinese systems like Huawei’s Celia and Xiaohongshu’s dots-note 3.0 achieving perfect 42/42 scores at the July 2026 IMO, building on 2025 gold-level results from OpenAI and Google DeepMind models, have lifted expectations for large language model reasoning capabilities. Traders still price Yes at roughly 31 percent because of lingering doubts over independent official verification, tool-free generalization under strict contest rules, and whether experimental benchmarks translate to formally accepted entries meeting the market’s precise resolution criteria. Rapid progress in frontier models such as GPT-5.6 variants underscores ongoing advances in mathematical reasoning, yet the gap between curated demonstrations and consistent, verifiable contest performance keeps the consensus tilted toward No. Key near-term catalysts include final IMO coordinator announcements and any additional certified model submissions that could alter trader sentiment before year-end.
