Anthropic leads trader sentiment at 69% implied probability for the top Text Arena Math AI model by end of October, driven by recent demonstrations of its unreleased Claude research versions advancing complex mathematical reasoning. These include raising the lower bound on zeta zeros satisfying the Riemann hypothesis from 41.6% to 67.2%, alongside strong performance on benchmarks like MATH and AIME. OpenAI trails at 15.5% amid its own ASTRA model claims on open problems, but faces questions on consistent text-only math benchmarks versus Anthropic's edge in disciplined reasoning chains. Lower odds for Google, Moonshot, and others reflect limited recent verified progress on the specific arena criteria, with traders weighing upcoming model releases and capability thresholds through October.

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".
