Description

These markets assess whether the S&P 500 index will surpass specific thresholds by the close of trading on July 31, 2026. Each threshold represents a progressively higher value, allowing participants to speculate on the magnitude of potential gains in the index by that date.

Kalshi

All markets share a common resolution framework: they resolve based on the end-of-day S&P 500 index value on July 31, 2026. Each market has a unique threshold, and if the index closes above that threshold, the market resolves to 'Yes'; otherwise, it resolves to 'No'. Markets close on July 31, 2026, and expiration occurs at the sooner of the first official data release or one week after the closing date. The Exchange has applied specific modifications to the source agency and underlying for all index-related markets as detailed in the Kalshi Rulebook.
