Anthropic's Claude models, including claude-opus-5-max and claude-fable-5 variants, hold the top positions on the arena.ai Text Arena Math leaderboard through August 27, driven by superior scores in competition-style math reasoning, human preference votes, and demonstrated capabilities on benchmarks like AIME and IMO-style problems. This dominance stems from recent model iterations emphasizing advanced reasoning chains and verifiable mathematical outputs, creating a clear gap over competitors such as Google Gemini and OpenAI GPT-5 series entries. Trader consensus at 99% implied probability for Anthropic reflects this sustained edge, though a last-minute high-performing release from another lab before the August 31 resolution could narrow the lead if it shifts the live rankings.

This market will resolve according to the company that owns the model that has the highest arena rank based on the arena.ai Text Arena (Math) when the table under the "Leaderboard" tab is checked on August 31, 2026, 12:00 PM ET.
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.
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".Anthropic's Claude models, including claude-opus-5-max and claude-fable-5 variants, hold the top positions on the arena.ai Text Arena Math leaderboard through August 27, driven by superior scores in competition-style math reasoning, human preference votes, and demonstrated capabilities on benchmarks like AIME and IMO-style problems.
