What counts
The market resolves by checking the Agent Arena Leaderboard at 12:00 PM ET on September 30, 2026. The outcome is Yes if OpenAI owns the model ranked highest in the 'Models' filter; otherwise, it is No. Readers often mistake the deadline for midnight or assume any OpenAI product counts instead of only the top-ranked model on that specific leaderboard.
Written from Polymarket's resolution rules by the same model that writes our headlines. The rules on Polymarket are what decides it.
