This market will resolve according to the company that owns the model that has the highest arena rank 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 "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 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 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.Anthropic commands 100% market-implied odds as the company with the best AI model end of April 2026, propelled by its Claude Opus 4.7 large language model securing the top rank on the Chatbot Arena LLM Leaderboard's Text Arena Overall tab (1504 Elo score). Released on April 16, this frontier model dominates key benchmarks like SWE-bench Verified (82% in coding) and excels in math and agentic tasks, maintaining a clear edge over rivals such as OpenAI's GPT-5.4 and Google's Gemini 3.1 Pro amid no competing launches in the final weeks. Amazon trails at 0.1%, reflecting its Bedrock hosting role without proprietary leadership. With resolution imminent at noon ET via lmarena.ai rankings, only an unforeseen last-minute model drop and leaderboard refresh could challenge this trader consensus, though release cadences make it unlikely.
