This event tracks the performance of a major stock market index at a specific future date and time, allowing participants to speculate on whether the index will surpass certain thresholds. The outcome depends solely on the index's value at the exact closing moment, reflecting broader economic and market conditions anticipated over the next several years.
All markets share the same underlying resolution criterion: the S&P 500 index value at 3pm EDT on October 26, 2026 must exceed a specified threshold for the market to resolve as 'Yes.' Each market defines a different threshold, creating multiple binary outcomes based on varying levels of index performance. All markets close on October 26, 2026, and expire either upon the first official release of the index value or one week after the closing date, whichever occurs first. The Exchange has applied specific modifications to the source agency and underlying assets for index-related markets as detailed in the Kalshi Rulebook.
