Trader consensus on Polymarket assigns a 96.7% implied probability to Anthropic claiming the #2 AI model on the LMArena Chatbot Arena leaderboard (Style Control On) by March 31, 2026, driven by Claude Opus 4.6-thinking's firm hold at #1 and the base Claude Opus 4.6 at #2 with a 1500 Elo score, unchanged since its early March release amid a flurry of competitor launches like xAI's Grok-4.20 beta (#4 at 1491 Elo) and Google's Gemini 3.1 Pro preview (#3 at 1493). This positioning reflects superior demonstrated capabilities in substance-focused evaluations that neutralize verbosity biases. Challenges could arise from a surprise update to Grok or Gemini before snapshot, or leaderboard volatility from new battles, though no such catalysts have emerged in the past week.
