**Claude Fable 5.1 Max leads market-implied odds at 86.5% for best AI model on September 14 because Anthropic released it on September 1 as the flagship Mythos-class model, immediately topping independent benchmarks such as the Artificial Analysis Intelligence Index at 66 and agentic coding evaluations.** Traders see its gains in long-horizon reasoning, tool use, and efficiency—delivering up to 45% lower cost on agentic workloads compared with Fable 5—as decisive for frontier capability. Prior Anthropic releases like Claude Opus 5 (July) and Fable 5 (June) now trail on updated leaderboards, while OpenAI’s GPT-6 Astra (September 3) has not displaced it. With the resolution date only days away, the market reflects rapid incorporation of the new model’s demonstrated performance edge in coding and knowledge work.

This market will resolve according to the model that has the highest arena rank based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab is checked on the specified date, 12:00 PM ET.
Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control with style control off (Adjustments: None) and filtered for "Models" will be used to resolve this market.
Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
No new model will be added to this market after market creation. Any model not explicitly listed in this market will be encompassed under the "Other" option.
Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie still remains, alphabetical order of model names as listed in this market group (full string, including suffixes such as “-high” and “-max”) will be used as a final tiebreaker (e.g., if two models remain tied, “claude-opus-5-high” would be ranked ahead of “claude-opus-5-max”). This market will resolve to the model that comes first according to this order.
The resolution source for this market is the arena.ai Text Arena (Overall). If this resolution source is unavailable at check time, this market will remain open until the leaderboard comes back online and will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve to "Other".**Claude Fable 5.1 Max leads market-implied odds at 86.5% for best AI model on September 14 because Anthropic released it on September 1 as the flagship Mythos-class model, immediately topping independent benchmarks such as the Artificial Analysis Intelligence Index at 66 and agentic coding evaluations.**
