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 specified moment, reflecting broader economic and market conditions projected into the future.
All markets share the same core resolution mechanism: each market resolves to 'Yes' if the S&P 500 index value at 10am EDT on August 10, 2026 exceeds a specific threshold (e.g., 7549.9999, 7554.9999, etc.). Thresholds vary incrementally across markets, creating a range of possible outcomes. All markets close on August 10, 2026, and expiration occurs at the sooner of the first official data release or one week after the specified date. The Exchange has applied modifications to the Source Agency and Underlying for index markets per the Kalshi Rulebook, ensuring consistent data sourcing and valuation methodology across all thresholds.
