Will OpenAI have the best AI model at the end of April 2026?
This Polymarket asks whether OpenAI will own the top-ranked AI model on the Chatbot Arena LLM Leaderboard at the time it is checked on April 30, 2026. Resolution is based on the highest arena score in the Text Arena Overall leaderboard with style control off, making this a direct bet on which company leads public model rankings at month-end. PolySpotter is currently tracking $1,090 in smart money activity on this market, including recent whale buys on Yes and OpenAI.
This market will resolve according to the company that owns the model that has the highest arena score based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on April 30, 2026, 12:00 PM ET. Results from the "Score" 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 ranked primarily by their arena score at this market’s check time, with alphabetical order of company names as listed in this market group used as a tiebreaker (e.g., if the two models are tied by arena score, “Google” would be ranked ahead of “xAI”). This market will resolve based on the company that occupies first place under this ranking. 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.
