Anthropic’s Claude lineup, led by Fable 5.1 at 65% and Opus 5 at 64.7% on recent September 2026 HLE snapshots, drives current market sentiment through iterative gains in reasoning, tool use, and adaptive evaluation setups on the 2,500-question benchmark. These scores reflect provider-reported results with tools and max-effort configurations that outpace OpenAI’s GPT-6 Astra and Meta’s Muse Spark variants, though text-only leaderboards show lower figures around the mid-50s. Traders watch for further 2026 releases or scaffold improvements that could push the highest Claude score toward or past 70% by year-end, while noting the benchmark’s remaining headroom and evaluation-condition sensitivities.

This market will resolve to "Yes" if any Anthropic Claude model achieves at least the specified accuracy on Humanity’s Last Exam by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No".
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.
