Description

These markets allow participants to speculate on the performance of a major stock market index at a specific future date and time. By dividing possible outcomes into narrow numerical ranges, investors can place bets on where the index will fall at the close of trading on that day.

Kalshi

Each market resolves based on the end-of-day value of the S&P 500 index on September 18, 2026, at 4pm EDT, with specific numerical ranges defining resolution outcomes. Markets close on September 18, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. All markets adhere to modified source agency and underlying rules for indices as specified in the Kalshi Rulebook. Resolution is determined strictly by where the index value falls within the defined ranges at the exact specified time, with no extensions or adjustments beyond the stated close and expiration parameters.
