These markets track the S&P 500 index value on July 20, 2026 at 10am EDT. Each market represents a specific price threshold, allowing traders to bet on whether the index will close above that level on the specified date and time.
The S&P 500 index will be measured on July 20, 2026 at 10am EDT. Markets resolve to Yes if the index value exceeds the specified threshold (e.g., above 7374.9999 for the 7,375 market, above 7379.9999 for the 7,380 market, and so forth across all price levels). Each market operates independently with its own threshold. The market will close on July 20, 2026 and expire at the sooner of the first release of the data or one week after July 20, 2026. Per the Kalshi Rulebook, the Exchange has modified the Source Agency and Underlying for indices markets.
