Anthropic's Claude Fable 5.1, released September 1, 2026, currently leads composite benchmarks such as BenchAlign v5 at 84.61 and tops Artificial Analysis Intelligence and coding indices through superior agentic workflows, long-context reasoning, and SWE-bench performance. This recent capability edge, paired with strong availability via API, drives the 76.5% market-implied probability that Anthropic holds the #1 model by end of October. OpenAI's GPT-6 Astra (September 3) trails slightly on several verified suites and faces greater access gating, while Google Gemini 3.8 Flash, Meta's Muse Spark, and Chinese labs like Moonshot or DeepSeek sit further behind on frontier metrics. Traders appear to price limited near-term leapfrogging risk before the resolution window, though new releases or benchmark shifts could still alter positioning.

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".
