What counts
The market resolves to Yes if OpenAI holds the top spot on the Chatbot Arena Text Leaderboard by December 31, 2026, at 11:59 PM ET. A tie for first place counts as a win. Readers often mistake the deadline for midnight UTC or assume any general AI ranking qualifies instead of the specific Chatbot Arena leaderboard.
Written from Polymarket's resolution rules by the same model that writes our headlines. The rules on Polymarket are what decides it.
