Description

This set of markets tracks the performance of a major stock market index on a specific date, resolving based on whether the index closes above various threshold values. Each market represents a different threshold, allowing participants to speculate on the exact level of the index at 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 October 20, 2026, at 4pm EDT. Each individual market has a specific threshold value; for a given market labeled 'X or above,' if the index closes above X.9999, the market resolves to 'Yes,' otherwise to 'No.' Markets close on October 20, 2026, and expiration occurs at the sooner of the official data release or one week after the close date. All markets adhere to modified source agency and underlying rules for indices as specified in the Kalshi Rulebook.
