Description

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 close time, reflecting broader economic expectations and market sentiment.

Kalshi

Each market within this event resolves based on whether the S&P 500 index value at 4pm EDT on September 21, 2026, exceeds a specific threshold, ranging incrementally from 7475 to 7770. All markets share identical secondary rules: they close on September 21, 2026, and expire either when the index value is first officially released or one week after the close date, whichever occurs sooner. The Exchange has applied modifications to the Source Agency and Underlying for indices markets as per the Kalshi Rulebook, ensuring consistent data sourcing and valuation methodology across all thresholds.
