Anthropic’s Claude Fable 5.1 and Opus 5 currently top HLE leaderboards at 59–65% across closed-book and tool-assisted variants, while OpenAI’s strongest reported models, including GPT-6 Astra and GPT-5.4 Pro variants, sit between 54.7% and 58.7% as of mid-September 2026. This gap reflects Anthropic’s recent emphasis on reasoning-focused training and post-training refinements that have widened its edge on the expert-curated, multi-domain benchmark. Traders are pricing in OpenAI’s capacity to narrow or close the difference before year-end through anticipated model updates, yet the market also accounts for the possibility that Anthropic or other labs maintain or extend their lead. Key catalysts ahead include any new OpenAI releases, competitive benchmark updates, and confirmation of evaluation protocols before the December 31 resolution.

This market will resolve to "Yes" if any model published by OpenAI 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. If no official alternative source is available, this market will resolve to "No".Anthropic’s Claude Fable 5.1 and Opus 5 currently top HLE leaderboards at 59–65% across closed-book and tool-assisted variants, while OpenAI’s strongest reported models, including GPT-6 Astra and GPT-5.4 Pro variants, sit between 54.7% and 58.7% as of mid-September 2026.
