The rules, in plain English
This market resolves to "Up" if the official Nikkei 225 Index closing price 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 official Nikkei 225 Index closing price on Friday, September 11, 2026 is lower than the official closing price on the most recent prior trading day. 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 compare to Thursday or the next most recent trading day. If the two closing prices are exactly equal, this market resolves 50-50. All figures are rounded to the nearest cent using standard rounding. If NIK does not trade at all during the regular session, the market resolves 50-50. If either of the relevant days are shortened (for example, due to a market holiday schedule), the official closing price published by Nikkei 225 Index for that shortened session will still be used. If either of the relevant days have 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.
