Which company has best AI model end of June?
💡 What the odds say
Most likely: Anthropic at about a 98% chance — almost certain.
Prediction-market odds are usually well-calibrated — historically, outcomes priced near 70% happen about 70% of the time — but the crowd can still be wrong, and the price can lag the news.
Summary
The prediction market heavily favors Anthropic at 98% to have the best AI model by end of June, with Google, OpenAI, and others each at 1% or less. This extreme concentration suggests traders see Anthropic as the clear frontrunner, likely due to recent model releases or competitive advantages. However, the near-zero odds for OpenAI and others may reflect uncertainty about their upcoming model performance or market sentiment shifts.

Resolution criteria
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.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.
