Anthropic's 68.5% implied probability stems from its Claude Fable 5, Mythos 5, and Opus 5 models holding the top ranks on the Text Arena math leaderboard through mid-2026, driven by superior performance in mathematical reasoning benchmarks and user-voted comparisons. These releases built on extended thinking capabilities and strong results in complex problem-solving, outpacing rivals on the specific arena platform that resolves the market. OpenAI (15.5%) and Google (10.8%) trail due to comparatively lower math-category Elo scores despite strengths in other domains, while lower-probability entrants like Moonshot or DeepSeek show niche benchmark leads but lack arena dominance. New model drops or leaderboard shifts before October end remain key swing factors in this closely watched tech race.

Results from the "Rank" column under the "Text Arena | Math" Leaderboard tab at https://arena.ai/leaderboard/text/math-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 (Math). 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".
