These markets allow traders to bet on specific price levels of the S&P 500 index at the close of trading on July 20, 2026 at 4pm EDT. Each market corresponds to a different threshold, enabling participants to express precise views on where the broad stock market index will settle on that date.
The S&P 500 price event on July 20, 2026 at 4pm EDT is structured as a series of threshold-based markets, each covering a specific price level in 5-point increments ranging from 7,375 to 7,670. For each market, resolution depends on whether the S&P 500 index value at the specified time exceeds the defined threshold by any amount. The official index value used for resolution will be determined by the first available data release following the market close, or if no data is released, one week after July 20, 2026, whichever occurs sooner. All markets in this event close on July 20, 2026. Per the Kalshi Rulebook, the Exchange has modified the source agency and underlying specifications for indices markets; traders should consult the rulebook for additional details on data sourcing and index calculation methodology.
