The market tracks the S&P 500 index value at the close of trading on August 13, 2026, resolving to 'Yes' if it exceeds specific thresholds from 7,575 to 7,870 points in increments of 5.
The market resolves based on the end-of-day S&P 500 index value on August 13, 2026, at 4pm EDT. Each market has a unique threshold; if the index closes above the specified level (e.g., 7,574.9999 for the first market, increasing by 5 points for each subsequent market), it resolves to 'Yes.' Markets close on August 13, 2026, and expire either when the index value is officially released or one week after the close, whichever comes first. All markets adhere to modified source agency and underlying rules for indices as per the Kalshi Rulebook.
