Trader consensus on Polymarket reflects a razor-thin race among frontier large language models, with Claude Opus 4.6, 4.7 variants (including thinking modes), Gemini 3/3.1 Pro preview, GPT-5.5 high, and Meta's Muse Spark all implying 41% odds of topping the LMSYS Chatbot Arena leaderboard on May 16 under style control off conditions. Anthropic's April 16 Claude Opus 4.7 release edged ahead in reasoning and coding benchmarks shortly after OpenAI's April 23 GPT-5.5 launch boosted agentic capabilities, while Google's February Gemini 3.1 Pro preview and Meta's April 8 Muse Spark multimodal advances kept pace in real-world Elo ratings. Differentiators include thinking chain transparency (Claude), speed/multimodality (Gemini), and efficiency (GPT-5.5), but no model dominates consistently; watch for pre-resolution updates or evaluations that could swing the closely contested standings.

Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://lmarena.ai/leaderboard/text with style control off will be used to resolve this market.
No new model will be added to this market after market creation. Any model not explicitly listed in this market will be encompassed under the "Other" option.
Models will be ordered primarily by their leaderboard rank at the market’s check time. If two or more models are tied on rank, they will be ordered by their Arena score, including any underlying, unrounded, granular values reflected in the data below the leaderboard. If a tie still remains, alphabetical order of model names as listed in this market group (full string, including suffixes such as “-thinking”) will be used as a final tiebreaker (e.g., if two models remain tied, “claude-opus-4-6” would be ranked ahead of “claude-opus-4-6-thinking”). This market will resolve to the model that comes first according to this order.
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 will resolve based on the first check after it becomes available. If it becomes permanently unavailable, this market will resolve based on another resolution source.
