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 June 30, 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 gives Anthropic a 53.5% implied probability for the second-best AI model by end of June 2026, driven by Claude Opus 4.6's consistent high rankings on LMSYS Chatbot Arena and other benchmarks like LiveBench, where it trails OpenAI's GPT-5.4 series in overall Elo scores but excels in complex reasoning and low hallucinations following its February release. Google's Gemini 3.1 Pro, bolstered by March updates like Flash-Lite for speed and multimodality, holds 25.5% as a close contender amid rapid iteration. DeepSeek's V4, launched mid-March with strong coding benchmarks at 1T parameters, fuels its 11.9% odds via cost-efficient open performance. Expect shifts from pre-June releases or LMSYS updates, as frontier large language models evolve quickly.
