Anthropic’s recent launch of Claude Fable 5.1 and Mythos 5.1 on September 1, 2026, has driven the 74% implied probability, as these models posted the highest scores on the Artificial Analysis Intelligence Index at 66 while excelling in coding, agentic workflows, and knowledge-work benchmarks such as Frontier-Bench and ARC-AGI 3. Traders see the combination of frontier performance, cost-efficient Opus 5 tier released in July, and consistent safety-focused releases as giving Anthropic a durable edge through October. OpenAI’s GPT-6 Astra and GPT-5.6 family, despite strong agentic and multimodal results, trail on composite intelligence metrics, while Google, Meta, and others lag further behind on verified capability demonstrations. The market reflects skin-in-the-game consensus on these near-term trajectories ahead of the October resolution.

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.
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".
