This set of markets tracks whether the S&P 500 index will reach or exceed various threshold values at a specific future date and time. Each market corresponds to a different numerical target, allowing participants to speculate on the precise level of the index at that moment.
All markets share identical resolution mechanics and secondary rules. Each market resolves to 'Yes' if the S&P 500 index value at 11am EDT on July 27, 2026 exceeds a specific threshold defined in the primary rule (e.g., above 7249.9999, above 7254.9999, etc.). The markets close on July 27, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. The Exchange has applied modifications to the Source Agency and Underlying for all index-based markets as per the Kalshi Rulebook.
