About this market
This market will resolve to "Yes" if a marketwide circuit breaker is triggered on the New York Stock Exchange (NYSE) at any time between November 7, 2025, and December 31, 2026. Otherwise, this market will resolve to “No”.

The primary resolution source for this market will be official information from the NYSE, however a consensus of credible reporting will also be used.
