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 speculate on where the market will land at the end of the trading 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 August 24, 2026, at 4pm EDT. Each market corresponds to a specific numerical range for the index's closing value, with one market designated for values at or below 7274.9999 and another for values at or above 7974.9999. All other markets cover consecutive 25-point intervals between these bounds. Markets close on August 24, 2026, and expiration occurs either when the index value is officially released or one week after the closing date, whichever comes first. Resolution is determined by comparing the officially reported closing value against the defined ranges for each market.
