Full rules

As written on Polymarket for “Will Meta have the best Math AI model at the end of October 2026?”.

1. §1This 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 October 31, 2026, 12:00 PM ET.
2. §2Results 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.
3. §3Note: Models marked “AutoEval” at the applicable check time will not be considered, regardless of whether they display a rank or score.
4. §4Models will be ordered primarily by their leaderboard rank at the market’s check time.
5. §5If 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.
6. §6If 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”).
7. §7This market will resolve based on the company that occupies first place under this ranking.
