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. If it becomes permanently unavailable, this market will resolve based on another resolution source.
Anthropic’s commanding lead at 66.5% implied probability stems from Claude Fable 5 and Opus 4.8 dominating recent LMSYS Arena and coding leaderboards, with top scores on SWE-bench Verified (around 88%) and strong results in long-horizon agentic and reasoning tasks. Developers continue favoring its nuanced output, safety alignment, and integration in tools like Cursor. OpenAI’s GPT-5.5 series holds steady as a versatile all-rounder for multimodal and agent workflows but trails in pure coding benchmarks. xAI’s Grok 4.x releases deliver competitive arena Elo and real-time X data advantages yet lag overall. With no major rival releases eclipsing Claude in the past month and Anthropic’s consistent frontier positioning, traders see limited near-term catalysts to shift the current consensus before year-end.
