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 different potential closing value for the index, allowing participants to assess where they believe the market will land by the end of the day.
The event resolves based on the end-of-day value of the S&P 500 index on August 03, 2026, with twenty-nine distinct numerical ranges and one overflow range determining the outcome. Each market corresponds to a specific value band, and only the market aligned with the actual closing index value resolves as 'Yes.' All markets close on August 03, 2026, and expiration occurs either upon data release or one week post-date, whichever comes first. The Exchange has applied modifications to the Source Agency and Underlying for index markets per the Kalshi Rulebook.
