Description

These markets track whether the S&P 500 index will close above specific thresholds on a particular date in 2026, allowing participants to speculate on future market performance without directly investing in stocks.

Kalshi

Each market resolves based on whether the S&P 500 index closes above a specified threshold on October 28, 2026, at 4pm EDT. All markets close on October 28, 2026, and expire either when the index data is first released or one week after that date, whichever comes first. The Exchange has adjusted the source agency and underlying rules for index markets as per the Kalshi Rulebook, but these adjustments do not alter the fundamental resolution criteria tied to the index's closing value.
