Description

This group of markets determines which company will have the best AI Agent at the end of October 2026, based on the Agent Arena Leaderboard rankings. The markets also include separate binary events for the release of OpenAI's GPT-6 model by various deadlines in 2026.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All markets within this group share consistent resolution criteria for their respective categories, with clear definitions for AI Agent rankings and GPT-6 release requirements.Primary resolution logic: Agent Arena Leaderboard for AI Agent rankings; Official OpenAI announcements and credible reporting for GPT-6 release

Core resolution logic:

  • AI Agent rankings resolve based on the Agent Arena Leaderboard as of October 31, 2026, excluding models marked 'AutoEval'
  • Ties in AI Agent rankings are broken by leaderboard position, then alphabetical order of company names
  • GPT-6 release markets require an explicitly named GPT-6 model, public announcement, and general accessibility by the specified deadline
  • Closed beta or private access does not satisfy GPT-6 release requirements

Edge cases & clarifications:

  • AutoEval Models: Models marked 'AutoEval' on the Agent Arena Leaderboard are excluded from ranking considerations regardless of displayed rank or score
  • GPT-6 Naming: Only models explicitly named GPT-6 (e.g., ChatGPT-6o) or recognized successors to GPT-5 count; products labeled GPT-5.5 or similar do not qualify
  • Public Accessibility: For GPT-6 release, public accessibility must include open beta or open rolling waitlist signups; closed beta or private access does not qualify
Timing: AI Agent rankings resolve as of October 31, 2026, 12:00 PM ET; GPT-6 release markets resolve on or after their respective deadlines (August 14, August 21, August 31, September 30, or December 31, 2026)Our 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 company that owns the model that has the highest rank based on the Agent Arena Leaderboard (https://arena.ai/leaderboard/agent) when the table under "Agent Arena" filtered for "Models" is checked on October 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Agent Arena" Leaderboard tab at https://arena.ai/leaderboard/agent 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 which model is listed higher on 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., “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 Agent Arena Leaderboard found at https://arena.ai/leaderboard/agent. 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.

Predict

This market will resolve to "Yes" if OpenAI's GPT-6 model is made available to the general public by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No." For this market to resolve to "Yes," GPT-6 must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be clearly defined and publicly announced by OpenAI as being accessible to the general public. GPT-6 refers to a product explicitly named GPT-6 (e.g. ChatGPT-6o would count), or one that is recognized as a successor to GPT-5, similar to the progression from GPT-3 to GPT-4. Products labeled as GPT-5.5 or similar will not count for this market's resolution. The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.
