This market will resolve to "Yes" if the next Anthropic Mythos-class model added to the Arena.AI Leaderboard (https://arena.ai/leaderboard/text/overall-no-style-control) has at least the specified score at 12:00 PM ET on the calendar date following the date on which it first appears on the leaderboard. 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. Results from the "Score" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off will be used to resolve this market. This market will resolve solely based on the specified score in the Score column of the leaderboard, regardless of any underlying granular or unrounded data presented elsewhere. A model marked "AutoEval" will not be considered added to the leaderboard. Only scores displayed without the "AutoEval" label will be considered. If multiple models are added to the leaderboard on the same calendar date (ET), the highest-scoring model will be used for resolution. Models added to the leaderboard on the calendar date following the initial qualifying model's first appearance will not be considered. If a model is first added to the Arena.AI Leaderboard but is subsequently removed and not re-added, such that it is not displayed on the leaderboard at 12:00 PM ET on the calendar date following its first appearance, its appearance will not qualify as added to the Arena.AI Leaderboard. A qualifying model must be newly added to the Arena.AI Leaderboard. Whether the model was previously released, publicly accessible, in beta, or otherwise available before appearing on the leaderboard is irrelevant for this market. The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://arena.ai/leaderboard/text/overall-no-style-control. 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 leaderboard, this market will resolve based on the first subsequent instance at which such a score becomes available on the leaderboard. If it remains unavailable through the end of the seventh day after the qualifying model first appears on the leaderboard or if no qualifying model release occurs by December 31, 2026, 11:59 PM ET, this market will resolve to "No".Anthropic’s June 2026 launch of public Claude Fable 5 alongside restricted Mythos 5 set the current Mythos-class baseline on benchmarks, with no official announcements, leaks, or new capability demonstrations since. Trader sentiment for the next model’s Text Arena (lmarena.ai/text) debut therefore hinges on Anthropic’s historical 3–5 month frontier cadence, balanced against potential delays from expanded safety reviews, compute limits, and regulatory oversight of agentic or cybersecurity features. Markets price a high probability of a qualifying release by year-end but reflect uncertainty around exact timing and leaderboard thresholds.
