The S&P 500 index is a key indicator reflecting the performance of 500 large-cap U.S. companies. On October 5, 2026 at 3pm EDT, the index's closing value will determine outcomes across multiple thresholds, offering insights into potential market optimism or pessimism at that specific moment.
All markets resolve based on the S&P 500 index value at 3pm EDT on October 5, 2026. Each market has a specific threshold; if the index closes above that threshold (e.g., 7,500.0000, 7,505.0000, up to 7,795.0000), the market resolves to 'Yes.' Markets close on October 5, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. All markets adhere to modified source agency and underlying rules for indices as per the Kalshi Rulebook.
