Circuit breakers halt stock market trading when the S&P 500 index falls sharply from the previous day’s close, to prevent panic selling. According to Investor.gov, a 7% drop triggers a 15-minute halt (Level 1), a 13% drop triggers another halt (Level 2), and a 20% drop stops trading for the rest of the day (Level 3). Circuit breakers can only trigger between 9:30 a.m. and 4:00 p.m. ET.

Recent example: On March 9, 2020, the S&P 500 triggered a halt shortly after opening amid COVID-19 fears.

Resolution criteria:

This market resolves YES if a Level 1, Level 2, or Level 3 circuit breaker halts trading on any U.S. stock exchange (e.g., NYSE or NASDAQ) between the time this question is posted and 4pm EDT on April 11th, 2025. It resolves NO if no halt is triggered during that time.
