This market will resolve according to the company that owns the model with 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 March 31, 2026, 12:00 PM ET. Results from the "Arena Score" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the style control off will be used to resolve this market. If two models are tied for the second 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 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 overwhelmingly favors Anthropic at 98.6% implied probability for the second-best AI model by end of March 2026, driven by the latest LMSYS Chatbot Arena leaderboard where Google's Gemini 3.1 Pro holds a slim lead at 1505 Elo over Claude Opus 4.6's 1503 Elo. Claude's February release of version 4.6 has cemented its runner-up status through dominant coding benchmarks, including 80.8% on SWE-bench Verified—surpassing GPT-5.4 and others—while maintaining strong general capabilities amid recent salvos from GPT-5.4 Thinking, Gemini 3.1 Pro, and DeepSeek V4. This positioning reflects aggregated skin-in-the-game bets on stable rankings, though a late xAI Grok update or surge in user votes could realistically flip the board before resolution.
