Anthropic’s strong implied probability of 70.5% stems from its Claude series, including recent Fable 5 and Mythos Preview variants, posting top scores on math-specific leaderboards such as Text Arena subcategories, LiveBench Mathematics, and MathArena evaluations through July and early August 2026. These models demonstrate superior performance on GSM8K, MATH, and AIME-style problems compared with GPT-5.6 Sol and Gemini 3.1 Pro. Lower odds for OpenAI (15.5%), Google (8.6%), and DeepSeek (6.8%) reflect their competitive but trailing benchmark results, while Chinese labs like Alibaba and Moonshot sit further back. Traders appear to weigh Anthropic’s consistent frontier releases and agentic reasoning gains against the possibility of rapid catch-up releases before the October resolution.

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".
