**Claude Fable 5.1-max dominates trader sentiment at 93.5% implied probability because Anthropic released it on September 1 as its flagship Mythos-class model, with clear gains over the prior Fable 5 and Opus 5 in agentic coding, long-horizon reasoning, and benchmarks such as SWE-bench Pro, LiveCodeBench, and the Vals Index.** It offers a 1M-token context window, adaptive thinking at max effort, and efficiency improvements that make it the strongest generally available option for demanding workloads just weeks before the September 21 snapshot. No other frontier model has launched or posted superior verified results in the interim. Realistic challenges include an unannounced competitor release from OpenAI or Google in the next few days, a sudden leaderboard shift on a key evaluation platform, or resolution criteria that favor a non-Anthropic model under specific conditions.

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 dominates trader sentiment at 93.5% implied probability because Anthropic released it on September 1 as its flagship Mythos-class model, with clear gains over the prior Fable 5 and Opus 5 in agentic coding, long-horizon reasoning, and benchmarks such as SWE-bench Pro, LiveCodeBench, and the Vals Index.**
