This market tracks where the S&P 500 index closes on July 20, 2026 at 4pm EDT. Traders predict which 25-point price range the index will fall into by end of day, with ranges spanning from below 7,175 to above 7,875.
Resolution is determined by the end-of-day S&P 500 index value on July 20, 2026. The index value is divided into consecutive 25-point ranges, with the lowest range covering values below 7,175 and the highest covering values at or above 7,875. Each range corresponds to a separate market outcome that resolves to Yes if the official closing value falls within that range. The market closes on July 20, 2026 and expires at the sooner of the first official data release or one week after July 20, 2026. Per the Kalshi Rulebook, the Exchange has modified the Source Agency and Underlying for indices markets.
