Anthropic’s recent Claude Fable 5.1, Opus 5, and Mythos 5 releases have established the current frontier on Humanity’s Last Exam, posting leading scores of 59–65% across major leaderboards as of mid-September 2026, ahead of OpenAI’s GPT-6 Astra and GPT-5.4 variants (54–58%) and Meta’s Muse Spark series. The 2,500-question benchmark, focused on expert-level reasoning across math, sciences, and humanities with verifiable but non-retrievable answers, has seen scores climb rapidly from single digits in early 2025 to the mid-50s and higher through iterative gains in chain-of-thought, adaptive reasoning, tool use, and scaling. With three months remaining in 2026, trader attention centers on whether new model drops, ensemble methods, or further reasoning enhancements can push the annual high beyond 65%, amid ongoing competition among closed frontier labs.

For resolution, “accuracy” refers solely to the value labeled “HLE Accuracy” or a clear equivalent metric if the data’s presentation or terminology is restructured, regardless of the model’s Calibration Error or any other displayed metric.
The resolution source will be the official Humanity’s Last Exam leaderboard at https://agi.safe.ai/. If the resolution source becomes unavailable during the listed timeframe, this market will remain open to allow the relevant data to become available again. If the source remains unavailable after the end of the listed timeframe or is otherwise confirmed to be permanently unavailable, official Humanity’s Last Exam results published elsewhere may be used.
