KalshiRules
This market will resolve according to the Close price for Opendoor Technologies Inc. (OPEN) on the final day of trading of the week specified in the title (normally Friday).
- If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.
- Closing prices will be used exactly as published by Pyth, without rounding.
- For a standard full trading session, the closing price refers to the Pyth "Close" value of the 1-minute candle corresponding to the final minute of regular trading hours on the primary exchange.
- If the relevant session is shortened (for example, due to a market-holiday schedule), the Pyth "Close" value of the 1-minute candle corresponding to the final minute of that shortened session will be used.
- If the relevant day has no valid Pyth Close value for the 1-minute candle corresponding to the end of regular trading hours on the primary exchange, the market will use the last valid Pyth price achieved during the regular trading hours of the primary exchange as the effective closing price.
