This market will resolve according to the company that owns the model that has the second-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 second 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.Trader consensus on Polymarket heavily favors Anthropic at 86.5% implied probability to hold the second-best AI model by April 30, driven by its Claude Opus 4.6 variants dominating the LMSYS Chatbot Arena leaderboard with Elo scores of 1504 and 1499, outpacing Google's Gemini 3.1 Pro preview at 1494. This positioning stems from Anthropic's recent model releases in late March, which captured both top spots across text, coding, and expert benchmarks, showcasing superior reasoning and instruction-following. Absent announcements of flagship updates from rivals like OpenAI (currently at 1463 Elo) or xAI, traders see limited upside for challengers, with Google's 6.5% reflecting modest gains possible from ongoing previews. Key resolution hinges on final Arena standings, with no major AI conferences or launches scheduled before month-end.
