Anthropic’s latest Claude variants, particularly Opus 5 and Mythos 5, have driven the current market positioning by posting leading scores of 64.7% and 64.5% on August 2026 Humanity’s Last Exam (HLE) leaderboards. These results stem from iterative advances in adaptive reasoning, tool integration, and long-context handling on the 2,500-question benchmark spanning math, sciences, and humanities. Other frontier models, including Meta’s Muse Spark 1.1 at 62.1%, trail closely, underscoring Anthropic’s competitive edge but also the narrow gap among top labs. With several months remaining until the December 31, 2026 resolution deadline, traders are watching for further Claude releases or evaluation refinements that could push scores higher while recognizing that benchmark saturation and evaluation conditions introduce ongoing uncertainty.

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".
