Recent benchmark updates show Claude Fable 5.1 leading independent leaderboards such as BenchLM and Artificial Analysis Intelligence Index with scores around 82.6 and 65.7, narrowly ahead of Claude Fable 5 and Opus 5. This September 1 release drives the 29% market-implied odds on its max variant, while Opus 5 variants sit close behind at combined 38.5% due to strong coding and agentic results at half the token cost. Other models from OpenAI and Google remain competitive in specific tasks like multimodal or throughput, creating uncertainty in a tight race where small benchmark shifts or new evaluations before September 21 could rebalance trader consensus.

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".
