Company with Best AI Model end of June 2026

How it works

You receive a US$1 return per contract if your prediction is correct and nothing if it is incorrect. The market resolves based on the highest ranking or score reported by a Source Agency (which may include Chatbot Arena LLM’s “Leaderboard” table; https://lmarena.ai/leaderboard/text) on June 30, 2026, 12:00 PM ET. If two models are tied for the top ranking or score reported by a Source Agency (which may include Chatbot Arena LLM’s “Leaderboard” table; https://lmarena.ai/leaderboard/text) on June 30, 2026, 12:00 PM ET, resolution will be based on whichever company's name, as it is described in the outcomes group, comes first in alphabetical order (e.g. if both were tied, "Google" would resolve to "Yes", and "xAI" would resolve to "No")is announced. 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/]. Liquidity may be low near the event's conclusion. Trading is temporarily paused during scheduled maintenance periods.
