Anthropic's Claude Opus 4.7 and Sonnet 4.6 currently anchor trader consensus at 92.5 percent for the best large language model by end of May, driven by consistent leadership on coding benchmarks such as SWE-bench and strong user reports for agentic workflows and natural prose generation. Recent releases from OpenAI and Google have narrowed gaps in reasoning and multimodal tasks, yet Anthropic's edge in practical developer adoption and lower hallucination rates on complex tasks has kept its position stable since early spring. With only two weeks remaining, any late-May update or major benchmark shift from competitors could introduce volatility, though no such announcements are confirmed on current timelines.

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.
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 remains, alphabetical order of company names as listed in this market group will be used as a final tiebreaker (e.g., if the two models are tied by exact arena score, “Google” would be ranked ahead of “xAI”). This market will resolve based on the company that occupies first place under this ranking system.
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.
