Recent benchmark leadership from Anthropic’s Claude Fable 5.1, released September 1 with top scores on agentic coding, automation, and reasoning evaluations, underpins the 58.5% implied probability for claude-fable-5.1-max. Traders see its gains over Fable 5 and competitive edge versus Opus 5 variants as decisive for a September 14 snapshot, though the tight clustering around 48–50% for Opus 5-high, Opus 5-max, and Opus 4.6-high reflects ongoing debate over cost-performance trade-offs and consistent real-world agentic results. The market treats these odds as aggregated sentiment on which model will demonstrate superior verified capabilities by the resolution date.

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".
