Description

These markets track whether the S&P 500 index will close above specific thresholds on a particular date, allowing participants to speculate on future market performance without directly investing in stocks.

Kalshi

All markets resolve based on the end-of-day S&P 500 index value on October 21, 2026, with each market requiring the index to close above a specific threshold to resolve as 'Yes.' Markets close on October 21, 2026, and expiration occurs at the sooner of the first 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.
