Description

This set of markets tracks potential future performance of a major stock market index on a specific date. Each market represents a different threshold value that the index might surpass or not by the close of trading on that day.

Kalshi

All markets in this event resolve based on the end-of-day value of the S&P 500 index on August 19, 2026. Each individual market has a specific threshold value; if the index closes above that threshold, the market resolves to 'Yes,' otherwise it resolves to 'No.' All markets close on August 19, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. The Exchange has applied specific modifications to the source agency and underlying for index markets as detailed in the Kalshi Rulebook.
