Anthropic's Claude Opus 4.6 commands a dominant 97.5% implied probability on Polymarket for owning the second-best AI model on the LMSYS Chatbot Arena leaderboard by March 31, as their non-thinking variant holds #2 at 1500 Elo—trailing only their own thinking variant at 1504—following the March 25 update. This positioning stems from consistent outperformance in crowdsourced blind battles across reasoning, coding, and creative writing, where Claude's long-context handling and safety-aligned outputs have garnered superior user votes over rivals. Google's Gemini 3.1 Pro preview lags at #3 (1493 Elo), xAI's Grok 4.20 beta at #4 (1491, preliminary), with minimal shifts in the past week. A late Grok or Gemini update could challenge this if it sparks rapid Elo gains before resolution, though tight timelines limit upset potential.
