This market will resolve according to the company that owns the model with the highest arena score based on the Chatbot Arena LLM Leaderboard when the table under the "Leaderboard" tab is checked on March 31, 2026, 12:00 PM ET. Results from the "Arena Score" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text set to default (style control on) will be used to resolve this market. If two models are tied for the best arena score at this market's check time, resolution will be based on whichever company's name, as it is described in this market group, comes first in alphabetical order (e.g., if both were tied, "Google" would resolve to "Yes", and "xAI" would resolve to "No") 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 resolves 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 99.3% implied probability of holding the top AI model on the LMArena Chatbot Arena leaderboard (Style Control On) at the end of March 2026, driven by Claude Opus 4.6's sustained #1 ranking since its early March release. This large language model has dominated blind human preference battles, outperforming rivals like Google's Gemini 3.1 Pro and OpenAI's GPT-5 variants through iterative updates, enhanced reasoning capabilities, and a robust Elo score above 1500. Anthropic's aggressive shipping cadence—over a dozen features including computer use and 1M-token context—solidified its lead amid fierce competition. While leaderboard stability near resolution supports this near-unanimous positioning, a surprise late-March model drop from xAI's Grok or a viral battle surge could theoretically challenge it, though traders see scant risk given recent trends.
