These markets allow participants to speculate on the performance of a major stock market index on a specific date. By investing in different outcome categories, traders can express their views on whether the index will fall within certain numerical ranges at the close of trading on that day.
All markets resolve based on the end-of-day value of the S&P 500 index on August 14, 2026, with each market covering a specific numerical range. If the index closes within a market's defined range, that market resolves as 'Yes'; all others resolve as 'No'. Markets close on August 14, 2026, and expiration occurs at the sooner of the official data release or one week after the close. The Exchange has applied specific modifications to the source agency and underlying assets for index-related markets per the Kalshi Rulebook.
Compared to traditional analyst forecasts, prediction market odds offer a real-time, crowd-sourced outlook shaped by trader activity. While analysts may publish target levels or ranges based on models and research, this market reflects aggregated bets that can react instantly to news, earnings reports, or macroeconomic data. Discrepancies between the two can signal emerging trends or divergences in market perception versus established research views.
This market resolves around Aug 14, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final settlement will compare the S&P’s closing value against the defined price bands, and the result will be finalized based on widely accepted sources. Timing aligns with the specified market close, ensuring a clear and objective resolution process.
Key signals include major economic reports such as inflation data, Federal Reserve policy decisions, and quarterly earnings from large S&P constituents. Geopolitical developments, sudden shifts in investor sentiment, or unexpected market corrections can also impact pricing. As Aug 14, 2026 approaches, traders will closely watch these catalysts, with any significant surprise potentially moving this market sharply in either direction.
