This event tracks the performance of a major stock market index on a specific date, dividing possible outcomes into narrow numerical ranges. Each range represents a potential closing value for the index, allowing participants to assess where they believe the market will land by the end of the day. The resolution depends solely on the index's final value at the specified time.
The event resolves based on the end-of-day value of the S&P 500 index on October 05, 2026, at 4pm EDT. Each market corresponds to a specific numerical range, and the market resolves to Yes if the index closes within that range. All markets close on October 05, 2026, and expiration occurs at the sooner of the first official data release or one week after the closing date. The Exchange has modified the Source Agency and Underlying for indices markets per the Kalshi Rulebook, which may affect data sourcing and validation procedures. Resolution is contingent upon accurate and timely publication of the index value by the designated source agency.
