Anthropic’s September 1 release of Claude Mythos 5.1, the latest in its restricted Mythos-class frontier models, is the dominant catalyst shaping trader views on a near-term HLE debut. The update delivered measurable gains in cybersecurity and biology while posting leading or near-leading closed-book scores on the September 2026 Humanity’s Last Exam leaderboard (Fable 5.1 at 65 percent, Mythos 5 at 64.5 percent), outpacing prior Opus variants and rivals such as GPT-5.4 Pro and Muse Spark. Limited access via vetted programs and added safeguards continue to constrain broader evaluation, yet the model’s rapid benchmark movement underscores Anthropic’s cadence of 3–5 month frontier cycles. Traders are watching for official HLE protocol details, potential tool-use variants, and any competitive responses from OpenAI or Google that could shift implied probabilities before year-end.

This market will resolve to "Yes" if the next Anthropic Mythos-class model added to the Humanity's Last Exam results at https://agi.safe.ai/ has an HLE Accuracy of at least the specified percentage at 12:00 PM ET on the calendar date following the date on which it first appears on the site. Otherwise, this market will resolve to "No".
Any model whose official name includes "Mythos," or "Fable" (e.g., Claude Fable 5.1 or Claude Fable 6), or that Anthropic officially describes as a "Mythos-class" model or similar, will qualify for this market's resolution. Anthropic's other model tiers, such as Opus, Sonnet, or Haiku, will not qualify.
The percentage displayed as "HLE Accuracy" for the model in its result card on the "AI Progress on Humanity's Last Exam" chart at https://agi.safe.ai/ will be used to resolve this market. This market will resolve solely based on the displayed HLE Accuracy, regardless of the model's Calibration Error, chart position, other configuration scores, or any underlying granular or unrounded data presented elsewhere.
If multiple qualifying models are added to the Humanity's Last Exam results on the same calendar date (ET), the model with the highest HLE Accuracy will be used for resolution. Models added to the results on the calendar date following the initial qualifying model's first appearance will not be considered. If a model is first added to the Humanity's Last Exam results but is subsequently removed and not re-added, such that it is not displayed on the site at 12:00 PM ET on the calendar date following its first appearance, its appearance will not qualify as added to the Humanity's Last Exam results.
A qualifying model must be newly added to the Humanity's Last Exam results at https://agi.safe.ai/. Whether the model was previously released, publicly accessible, in beta, or otherwise available before appearing on the site is irrelevant for this market.
The resolution source for this market is the official Humanity's Last Exam website found at https://agi.safe.ai/. If this resolution source is unavailable at 12:00 PM ET on the calendar date following the date on which the qualifying model first appears on the site, this market will resolve based on the first subsequent instance at which the model's HLE Accuracy becomes available on the site. If it remains unavailable through the end of the seventh day after the qualifying model first appears on the site or if no qualifying model is added by December 31, 2026, 11:59 PM ET, this market will resolve to "No".Anthropic’s September 1 release of Claude Mythos 5.1, the latest in its restricted Mythos-class frontier models, is the dominant catalyst shaping trader views on a near-term HLE debut.
