These markets allow traders to bet on where the S&P 500 index will close on July 21, 2026 at 4pm EDT. Each market represents a different price level, with traders wagering whether the index will finish above or below specific thresholds ranging from 7,300 to 7,595.
The S&P 500 index value will be measured at end-of-day on July 21, 2026. Each market resolves to Yes if the closing index value exceeds its specified threshold (e.g., above 7,299.9999 for the 7,300 market, above 7,304.9999 for the 7,305 market, and so forth through 7,595). The market closes on July 21, 2026 and expires at the sooner of the first official data release or one week after July 21, 2026. Per the Kalshi Rulebook, the Exchange has modified the Source Agency and Underlying for indices markets.
