Anthropic's latest Claude variants, including Fable 5 and Opus 5, currently lead Humanity's Last Exam with scores around 55-65% on independent leaderboards, driven by targeted advances in adaptive reasoning, chain-of-thought techniques, and max-effort inference modes. This marks a sharp rise from single-digit results in early 2025 as frontier labs scale large language models with improved benchmarks in expert-level science, math, and multi-step problem solving. OpenAI's GPT-5.6 Sol and Google's Gemini 3 series trail closely, while Meta and others push competitive releases. Traders price in continued gains through year-end model iterations, though saturation risks and architectural limits create uncertainty around crossing 65%+ thresholds before December 2026.

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. If no official alternative source is available, this market will resolve to "No".
