This market asks whether OpenAI will be the company behind the model ranked third on the Chatbot Arena LLM Leaderboard at the end of June 2026. It is a straightforward way to track how OpenAI’s top public model compares with rivals like Google, Anthropic, xAI, and others on a specific third-party benchmark that many AI watchers follow.
Resolution is tied to the "Text Arena | Overall" leaderboard on lmarena.ai, checked on June 30, 2026 at 12:00 PM ET. The market will look at the "Rank" column with style control off, and it will use the company that owns the model sitting in third place under that ranking system. If two models are tied, the market rules break the tie by Arena score, then by the alphabetical order of company names listed in the market group.
OpenAI is a major developer of general-purpose AI models, so whether it holds the third spot on a public arena leaderboard is a useful snapshot of its relative position in a fast-moving field. The uncertainty comes from the fact that leaderboard positions can change as companies release new models, update existing ones, or improve benchmark performance over time. Readers following this market are really watching whether OpenAI stays near the top tier, slips behind competitors, or gets overtaken by another lab by the June 2026 cutoff.
A new OpenAI model, a major quality jump in an existing model, or a strong public showing on Chatbot Arena could make a "Yes" outcome look more plausible. The same would be true if rival companies such as Google, Anthropic, or xAI launch models that climb above OpenAI’s best entry on the leaderboard. Because the market uses the exact leaderboard rank at a fixed check time, even modest score changes, tie-breaker outcomes, or a late leaderboard update could matter.
The current market price implies roughly a 3% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.

View marketThe key thing to verify is the exact Chatbot Arena leaderboard page used in the rules: the "Text Arena | Overall" tab with style control off, checked at 12:00 PM ET on June 30, 2026. Since the market resolves by company ownership rather than model name, readers should pay attention to which company is attached to the model in third place, not just the model title itself. The rules also say the market stays open if the leaderboard is temporarily unavailable, so any outage or delayed refresh at the check time could affect when the result is finalized.

This market is currently listed with an end date of Jun 30, 2026. Market timelines can change if the underlying event is postponed, rescheduled, or resolved early.
This market will resolve according to the company that owns the model that has the third-highest arena rank based on 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" column under the "Text Arena | Overall" Leaderboard tab at https://lmarena.ai/leaderboard/text with 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 third 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 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.
