Which company has the best AI model end of June 2026? (LMArena)

Prediction market on manifold. Resolution is based on the chatbot arena LLM leaderboard (https://lmarena.ai/leaderboard/text/overall-no-style-control), specifically the company with the highest Arena Score in the Overall category, without style control or show deprecated, at the end of June 30th, 11:59PM ET. We'll follow polymarket's tiebreak rule: If two models are tied for the highest arena score at this market's check time, resolution will be based on whichever company's name, as it is described in this market group, comes first in alphabetical order (e.g., if both were tied, "Google" would resolve to "Yes", and "xAI" would resolve to "No") See also: @/Bayesian/which-company-has-the-best-ai-model-hnNnI6lALy @/Bayesian/which-company-has-the-best-ai-model-LIC6U8LQ9R @/Bayesian/which-company-has-the-best-ai-model-0PE9Utg8Qg Previous months: @/Bayesian/which-company-has-best-ai-model-end @/Bayesian/which-company-has-best-ai-model-end-I0QsydsZuz @/Bayesian/which-company-has-best-ai-model-end-0CRdhqptRl @/Bayesian/which-company-has-best-ai-model-end-uIgZPlOt5d @/Bayesian/which-company-has-best-ai-model-end-A88UsyhdZz @/Bayesian/which-company-has-best-ai-model-end-IZEIlPL8ZZ @/Bayesian/which-company-has-best-ai-model-end-5Ch5LQddE5 @/Bayesian/which-company-has-best-ai-model-end-96p0nLU5A5 @/Bayesian/which-company-has-best-ai-model-end-spP5uLOAQR @/Bayesian/which-company-has-best-ai-model-end-QcqLtdnQnN
