These markets track whether the S&P 500 index will surpass specific thresholds by a precise date and time, allowing participants to speculate on future market performance without direct investment in stocks.
Each market resolves based on whether the S&P 500 index value at 2pm EDT on August 10, 2026 exceeds a defined threshold. All markets close on August 10, 2026, and expire either when the index data is first released or one week after the close date, whichever comes first. The Exchange has applied modifications to the Source Agency and Underlying for indices markets as per the Kalshi Rulebook.
