Description

This group of markets asks which AI lab will be ranked second overall based on the arena.ai Text Arena leaderboard at the end of October 2026. The ranking considers 'Lab Rank' primarily, with tiebreakers based on model scores and alphabetical order. Models marked 'AutoEval' are excluded from consideration.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both Polymarket and Predict use identical resolution criteria based on the arena.ai Text Arena leaderboard, including the same filtering, tiebreaker rules, and exclusion of 'AutoEval' models.Primary resolution logic: arena.ai Text Arena (Overall) Leaderboard: https://arena.ai/leaderboard/text/overall-no-style-control?rankBy=labs

Core resolution logic:

  • Rank AI labs based on 'Lab Rank' column on the arena.ai leaderboard.
  • Exclude models marked 'AutoEval' from the ranking.
  • If Lab Rank is tied, use Arena score (including granular values) as a tiebreaker.
  • If Arena score is tied, use alphabetical order of lab names as a final tiebreaker.

Edge cases & clarifications:

  • Leaderboard Unavailable: If the arena.ai leaderboard is unavailable at the check time, the markets will remain open until it becomes available. If it becomes permanently unavailable, the markets will resolve to 'Other'.
  • Ambiguous Ranking: If the results based on the lab ranking are ambiguous, the relevant AI companies will be ordered according to their highest-ranking AI model in the leaderboard’s “Models” view.
Timing: October 31, 2026, at 12:00 PM ETOur PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This market will resolve according to the second-highest ranked Company based on the arena.ai Text Arena (Overall) when the table under the "Leaderboard" tab filtered for "Labs" is checked on October 31, 2026, 12:00 PM ET. Results from the "Lab Rank" column under the "Text Arena | Overall" Leaderboard tab at https://arena.ai/leaderboard/text/overall-no-style-control?rankBy=labs with style control off (Adjustments: None) and filtered for "Labs" 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. AI companies will be ordered primarily by their Lab Rank at the market’s check time. If the results based on the lab ranking are ambiguous or unavailable, the relevant AI companies will be ordered according to their highest-ranking AI model in the leaderboard’s “Models” view. 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 AI lab/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 second place under this ranking. The resolution source for this market is the arena.ai Text Arena (Overall). 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".
