Claude Fable 5.1 Max leads trader sentiment at 86.5% implied probability for best AI model on September 14 due to its September 1 release as Anthropic’s frontier large language model. It delivers substantial gains in long-horizon agentic coding, multistep research, and complex knowledge work over Fable 5, with standout benchmark results including 52.6% on Terminal-Bench-Science 0.1 and top scores on BenchAlign and HLE leaderboards. These verified improvements, plus reduced effective costs through cheaper cache reads, have quickly established it ahead of Opus 5 variants and other competitors. With the market resolving in four days, the recent official launch and independent evaluations continue to anchor the overwhelming consensus among traders.

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".
