Anthropic’s Claude Opus 4.7, released in mid-April, continues to top independent benchmarks on coding, reasoning, and safety metrics, giving traders strong conviction that the company will hold the number-one model through the end of May. Its edge in real-world agentic tasks and consistent leaderboard leadership has pushed market-implied odds above 90 percent. Google’s Gemini updates and OpenAI’s incremental GPT-5.5 refinements have narrowed the gap on some narrower evaluations but have not displaced Claude’s overall lead. A late-May surprise release or dramatic benchmark jump from either rival could still shift the outcome, yet the current pace of verified progress leaves little room for such a reversal before the resolution date.

Results from the "Rank" column under the "Text Arena | Overall" Leaderboard tab at https://lmarena.ai/leaderboard/text with style control on 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.
