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 exact level of the index at that moment.
All markets share the same core resolution mechanism: each resolves to 'Yes' if the closing S&P 500 index value at 1pm EDT on July 27, 2026 exceeds its specific threshold (e.g., 7,250, 7,255, etc.). The thresholds vary incrementally across markets, creating a range of possible outcomes. All markets close on July 27, 2026, and expire either when the index data is first officially released or one week after the close date, whichever occurs first. The Exchange has applied standardized modifications to the source agency and underlying assets for all index-based markets per the Kalshi Rulebook.
