How it works

This market will resolve to "Yes" for the company whose AI model holds the highest ranking or score reported by a Source Agency (which may include Chatbot Arena LLM's "Leaderboard" table; https://lmarena.ai/leaderboard/text) at 12:00 PM ET on June 30, 2026. All other outcomes will resolve to "No". If two or more companies are tied for the top ranking or score reported by the Source Agency at 12:00 PM ET on June 30, 2026, the market will settle at 1/n, where n is the total number of tied companies. The official resolution sources are the agencies listed in Rule 14.68(c) in the CDNA Rulebook, which can be found [here](https://www.nadex.com/rules/).
