The rules, in plain English

This market resolves to "Up" if the official NYSE Composite Index closing price for NYA on Friday, September 11, 2026 is higher than the official closing price on the most recent prior trading day. This market resolves to "Down" if the September 11, 2026 closing price is lower than the most recent prior trading day's closing price. For example, a market on Monday would normally compare to the previous Friday, unless that Friday was a market holiday, in which case it would use Thursday or the next most recent trading day. If the two closing prices are exactly equal, this market resolves 50-50. All figures will be rounded to the nearest cent using standard rounding. If NYA does not trade at all during the regular session, the market resolves 50-50. If either relevant day is shortened (for example, due to a market holiday schedule), the official closing price published by NYSE Composite Index for that shortened session will still be used. If either relevant day has no official closing price (for example, due to a trading halt into the market close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price. The resolution source is the Wall Street Journal, specifically the Close values published by the WSJ under "Historical Prices" at the provided URLs.

What the rules leave open

  • Whether the Wall Street Journal's published Close values are considered the official NYSE Composite Index closing price, or if WSJ is merely the source for verifying the official NYSE price.
