This market will resolve according to the company that owns the model that has the highest arena rank based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab for "Math" is checked on July 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 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 “xAI”). This market will resolve based on the company that occupies first place under this ranking. The resolution source for this market is the Chatbot Arena LLM Leaderboard found at https://lmarena.ai/. 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 based on another resolution source.

On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. On Polymarket, each company outcome is priced as a separate contract, with the sum of all outcome probabilities equaling 100 percent. The price of each contract reflects the market's collective belief in that company's likelihood of being deemed to have the best Math AI model by Jul 31, 2026. Traders buy and sell these contracts based on new model announcements, benchmark results, and evolving assessments of mathematical reasoning capabilities. The continuous order book ensures prices update in real time as new information emerges.
Major catalysts include new model releases or updates from leading AI labs, publication of peer-reviewed papers demonstrating superior mathematical reasoning, performance on high-profile benchmarks like MATH, Olympiad datasets, or theorem-proving tasks, and announcements of partnerships or breakthroughs in symbolic reasoning. Shifts in industry consensus, acquisition of specialized AI teams, and real-world applications solving complex mathematical problems could all influence market pricing. Media coverage of AI safety and capability comparisons may also sway trader sentiment as the July 2026 resolution date approaches.
