Trader consensus on Polymarket heavily favors Anthropic's Claude series at 67% implied probability for the third-best AI model by May 31, driven by recent Arena.ai leaderboard dominance in coding, document reasoning, and text categories where Claude Opus 4.7 Thinking claims top spots as of May 12. OpenAI's GPT-5.5 High, released May 5 as ChatGPT's new default, holds strong overall balance in expert tasks and math, while Google's Gemini 3.1 Pro excels in creative writing, positioning them as likely top-two frontrunners. Google's 34% odds reflect its competitive edge and potential pre-deadline updates, amid a tight race narrowed by rapid releases like Anthropic's 4.7 variants. No major shifts expected absent surprise announcements, with resolution hinging on final LMSYS-style Elo rankings.

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.
