This set of markets tracks whether the S&P 500 index will close above various threshold values on a specific date. Each market has a different threshold, allowing participants to speculate on the exact level of the index at the end of trading on that day.
All markets resolve based on the end-of-day value of the S&P 500 index on October 06, 2026, at 4pm EDT. Each market has a specific threshold value; if the index closes above that threshold (rounded down to four decimal places), the market resolves to Yes. Markets close on October 06, 2026, and expiration occurs at the sooner of the first official data release or one week after the close date. All markets adhere to modified source agency and underlying rules for indices as specified in the Kalshi Rulebook.
