What this market asks

Will Z.ai have the best AI model at the end of June 2026?

Current market read

This market asks whether Z.ai will have the best AI model at the end of June 2026, based on the company whose model ranks first on the Chatbot Arena LLM Leaderboard at the specified check time. It is one outcome market within the broader event "Which company has best AI model end of June?". The current market-implied probability for Z.ai is 0.05%, with 24h movement unavailable.

Key takeaways

  • This outcome's market activity shows very low current market-implied probability at 0.05%.
  • The market has substantial overall volume and liquidity, indicating ongoing attention to the broader AI leaderboard event.
  • This is one outcome within a grouped event, so the volume and liquidity reflect trading on Z.ai only, not the entire event.

Risks & uncertainties

  • 24h movement is unavailable in the stored top-level data.
  • Resolution depends on the Chatbot Arena leaderboard being available at the check time, with fallback handling if it is not.
  • This is a grouped outcome market, so activity figures do not represent the full multi-outcome event.

Resolution summary

The market is set to resolve using the Chatbot Arena LLM Leaderboard on lmarena.ai, specifically the "Rank" section on the Leaderboard tab with the style control off, checked on June 30, 2026 at 12:00 PM ET. The company whose model is ranked first under the stated ranking and tiebreak rules resolves the market. If the leaderboard is unavailable at check time, the market stays open until it returns; if it becomes permanently unavailable, another resolution source would be used. No separate resolution-source field is stored; resolution details are based on the market description.

Resolution Rules

Resolves Yes if …

This market will resolve according to the company which owns the model which has the highest arena rank based off the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on June 30, 2026, 12:00 PM ET. Results from the "Rank" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the 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 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 system. 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 resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.

Resolves No if …

No otherwise — if the Yes condition is not satisfied by the resolution criteria.

Important caveats

This market resolves according to the source market rules. Review the source market before relying on this interpretation.

Resolution deadline: 30 Jun 2026, 00:00 UTC
