Anthropic leads trader sentiment at 66.5% implied probability for the best AI model by end of 2026, driven by consistent frontier performance from its Claude large language models in recent benchmarks and capability demonstrations that outpace competitors. OpenAI follows at 11% amid ongoing GPT iterations and scaling efforts, while xAI at 9% and Google at 8.5% reflect targeted progress in specialized reasoning and multimodal systems. Key recent catalysts include Anthropic's model updates enhancing safety-aligned capabilities and developer adoption, alongside competitive responses from rivals. Upcoming factors such as next-generation releases and third-party evaluations could shift consensus, though current market-implied odds highlight Anthropic's edge in demonstrated technical leadership.

This market will resolve according to the company which owns the model which has the highest arena rank based off the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab is checked on December 31, 2026, 12:00 PM ET.
Results from the "Rank" section on the Leaderboard tab of https://lmarena.ai/leaderboard/text with the 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 resolve based on the first check after it becomes available.
