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% implied probability of holding the second-best AI model by June 30, 2026—likely resolved via LMSYS Chatbot Arena leaderboard—driven by Claude Opus 4.6's consistent high rankings in reasoning and low hallucination benchmarks, trailing only OpenAI's dominant GPT-5.4. Google's Gemini 3.1 Pro Preview, at 25%, remains a close contender thanks to March 2026 multimodal upgrades and vast context windows, but traders doubt it overtaking Claude without a major Q2 leap. DeepSeek's 12.3% reflects hype around its efficient V4 release expected this quarter, challenging incumbents on open-weight leaderboards. Key catalysts include pending Anthropic announcements and xAI's Grok 5, amid rapid iteration cycles where even small benchmark gains can shift standings.
