This market will resolve according to the company that owns the model that has the highest arena rank (Style Control On) based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on May 31, 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 on 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.Trader consensus on Polymarket assigns Anthropic a 69% implied probability of holding the #1 spot on the LMSYS Chatbot Arena leaderboard (Style Control On) by May 31, driven by Claude Opus 4.7's release on April 16, which propelled it to the top with superior performance in substance-focused evaluations that minimize stylistic biases. This edges out Google's Gemini 3.1 Pro Preview at second place (27% odds), reflecting Anthropic's edge in agentic tasks and coding benchmarks amid a tight U.S. closed-source frontier race. OpenAI's GPT-5.5 trails due to weaker showings here despite all-around strengths, while others lag. Key catalysts ahead include potential Google or OpenAI updates before month-end, though Anthropic's momentum and preview of unreleased Claude Mythos suggest sustained leadership barring surprises.
