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 closing moment on August 31, 2026, at 3pm EDT.

Kalshi

All markets share the same core resolution mechanism: each market resolves to 'Yes' if the S&P 500 index value at 3pm EDT on August 31, 2026, exceeds a specific threshold (e.g., 7574.9999, 7579.9999, etc.). The thresholds vary incrementally across markets, creating a range of possible outcomes. All markets close on August 31, 2026, and expire either when the index value is officially released or one week after the closing date, whichever comes first. The Exchange has applied modifications to the Source Agency and Underlying for indices markets as per the Kalshi Rulebook, ensuring consistent data sourcing and calculation methodologies across all markets.
