Traders view Claude Fable 5.1 Max as the leading contender for best AI model on September 21, with a 57.5% implied probability reflecting recent Anthropic releases that delivered measurable gains in reasoning benchmarks and large language model capabilities. The sizable 33.5% share for Other signals ongoing uncertainty around competing releases from labs like OpenAI or Google, while the sub-4% odds on various Claude Opus variants suggest traders see limited upside for those earlier iterations. Competitive positioning, developer feedback on safety and performance, and typical release cycles in the AI space underpin current sentiment. With resolution just weeks away, any new model announcements or third-party evaluations could still shift probabilities before the cutoff.

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".
