Anthropic holds a commanding 77% market-implied probability for the top AI model by end of October due to its September 1 release of Claude Fable 5.1, which leads independent leaderboards including the Artificial Analysis Intelligence Index and BenchAlign v5 with scores around 83, outperforming OpenAI’s newly released GPT-6 Astra. Strong showings from related models like Claude Opus 5 on coding, agentic reasoning, and knowledge-work benchmarks such as SWE-bench and GDPval-AA have reinforced trader consensus on sustained frontier positioning. OpenAI at 8.9% and Google at 6.9% reflect competitive but trailing releases, while lower odds for Meta, Moonshot, and others highlight gaps in verified capability demonstrations. With resolution tied to LMSYS Arena or similar metrics under style control, any late-October model updates could still shift sentiment before the October 31 cutoff.

Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall with style control on (Adjustments: Style Control) 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.
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 company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Google” would be ranked ahead of “SpaceXAI”). This market will resolve based on the company that occupies first place under this ranking.
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".
