OpenAI’s GPT-5.6 Sol has already reached 49.5% on Humanity’s Last Exam, a 2,500-question PhD-level benchmark spanning advanced math, science, and specialized domains, placing the model just below leading Claude variants at 54–55%. Trader consensus heavily favors the 50%+ outcome at 93% implied probability because frontier labs continue to post double-digit gains every few months through scaled training, adaptive reasoning techniques, and iterative releases. OpenAI’s substantial compute resources and rapid GPT-5.x cadence give it a clear path to close the small gap before year-end, though Anthropic’s edge in recent evals and any unexpected delays in OpenAI’s next major update remain the primary swing factors.

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".
