Trader consensus on Polymarket overwhelmingly favors Google at 96.1% implied probability for holding the #3 spot on the LMArena.ai (formerly LMSYS Chatbot Arena) text leaderboard with Style Control On as of March 31, 2026, driven by Gemini 3.1 Pro Preview's stable 1493 Elo rating from over 15,800 blind pairwise battles—firmly behind Anthropic's two Claude Opus 4.6 variants at 1504 and 1500 Elo but ahead of xAI's Grok-4.20-beta1 at 1491 Elo. Recent voting surges through March 29 have reinforced Gemini's advantages in reasoning and content quality, solidifying its position amid a flurry of March frontier model releases like Claude 4.6 and Grok 4.20. With resolution imminent and high battle volumes reducing volatility, upset scenarios remain limited to improbable late surges for challengers like xAI or a surprise model entry overtaking #3 in final hours.
