Anthropic holds a narrow edge in trader sentiment for the end-of-September 2026 #1 AI model under Style Control On, reflecting its recent benchmark dominance with Claude Fable 5 and Opus 4.8 topping composite quality and coding metrics like SWE-Bench. These models emphasize substantive reasoning over formatting, aligning directly with the resolution criteria that neutralize presentation advantages. Close competition from OpenAI’s GPT-5.6 Sol and GPT-5.5 Pro, plus Google’s Gemini 3.1 Pro in accuracy and reasoning tasks, keeps multiple outcomes near even odds. Key swing factors include any September frontier releases, continued leaderboard shifts on LMSYS Arena, and how well each lab sustains gains in instruction-following and agentic capabilities amid rapid iteration cycles.

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.
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".
