These markets allow traders to bet on where the S&P 500 index will trade at 1pm EDT on July 20, 2026. Each market represents a different price level, with traders wagering on whether the index will close above or below specific thresholds ranging from 7,375 to 7,670.
The S&P 500 price markets on July 20, 2026 at 1pm EDT are structured as a series of binary outcomes across multiple price thresholds, each separated by 5-point increments. Each individual market resolves to Yes if the S&P 500 index value at the specified time exceeds its respective threshold (e.g., above 7374.9999 for the 7,375 market, above 7379.9999 for the 7,380 market, and so forth through 7,670). The markets will close on July 20, 2026 and expire at whichever occurs first: the initial release of the official index data or one week after July 20, 2026. Per the Kalshi Rulebook, the Exchange has modified the source agency and underlying specifications for indices markets. Traders can use these tiered price levels to express granular views on the index's performance on that date, with each threshold offering discrete betting opportunities across the full range of potential outcomes.
