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 predetermined moment, reflecting broader economic expectations and market sentiment.
Each market evaluates whether the S&P 500 index value at 10am EDT on October 26, 2026, exceeds a specific threshold, with thresholds incrementally increasing from 7,500 to 7,795. All markets close on October 26, 2026, and expire at the sooner of the first official data release or one week after that date. Resolution is based exclusively on the index value at the exact specified time, with no additional performance calculations or adjustments. The Exchange has implemented modified source agency and underlying rules for index markets as per the Kalshi Rulebook, but these modifications do not alter the core resolution mechanism for these markets.
