This event tracks the closing value of the S&P 500 index on July 17, 2026 at 4pm EDT. The S&P 500 is a major stock market index representing 500 large-cap U.S. companies and is considered the primary benchmark for the overall health of the American equity market. Resolution depends on the official end-of-day index value.
The market resolves based on the end-of-day S&P 500 index value on July 17, 2026. Each outcome corresponds to a specific price threshold, with resolution occurring if the index closes above that threshold. Thresholds range from 7,400 to 7,650 and increment by 5 points. The market closes on July 17, 2026 and expires at the sooner of the first data release or one week after that date. Per Kalshi's rulebook, the source agency and underlying for indices markets have been modified.
