Description

This market will resolve to "Up" if the official S&P 500 Index open price for S&P 500 (SPX) on November 2 is higher than the official S&P 500 Index closing price for SPX on the most recent prior trading day. This market will resolve to "Down" if the official S&P 500 Index open price for S&P 500 (SPX) on November 2 is lower than the official S&P 500 Index closing price for SPX on the most recent prior trading day. E.g., ordinarily, a market on Monday would refer to the previous Friday for its most recent closing price, unless that Friday were a market holiday, in which case it would refer to Thursday, or the next most recent trading day. If the two prices are exactly equal, this market will resolve 50-50. Note that all figures will be rounded to the nearest cent using standard rounding. If SPX does not trade at all during the regular session, the market will resolve 50-50. If either of the relevant days are shortened (for example, due to a market holiday schedule), the official open/close price published by S&P 500 Index for that shortened session will still be used for resolution. If the previous trading day has no official closing price (for example, due to a trading halt into the market close, system issue, delisting, or other disruption), the market will use the last valid on-exchange trade price of the regular session as the effective closing price. The resolution source for this market is the Wall Street Journal, specifically the Open/Close values published by the WSJ under "Historical Prices".

Frequently asked questions

On Polymarket, the dashboard for the S&P 500 opening direction market displays the current odds of the index opening up or down on November 2. You can view the price history of this market, allowing you to analyze how predictions have shifted over time. The dashboard also shows the 24-hour trading volume, currently at $4,783, and the total volume traded to date, which is $4,785. These metrics give a sense of how actively traders are participating in this market and how much confidence they have in their predictions.

Currently, prediction market odds reflect a different perspective than many traditional analyst forecasts. While some analysts predict a moderate increase in the S&P 500, this market shows a more nuanced view, with traders weighing various economic indicators and potential catalysts. It’s important to remember that analyst forecasts are often based on models and assumptions, while this market represents the collective judgment of individuals putting their capital at risk. This difference highlights the potential value of prediction markets as a source of alternative insights.

On Polymarket, this market is priced through a continuous auction mechanism, where traders buy and sell shares representing their belief about the S&P 500’s opening direction. The price of these shares directly reflects the probability of each outcome – an upswing or a downswing. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. The market price adjusts dynamically based on supply and demand, meaning that as more people bet on one outcome, the price of shares representing that outcome will increase, and vice versa. This creates a real-time assessment of market sentiment.

This market resolves around Nov 2, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the direction of the S&P 500’s opening price on November 2 will be used to determine whether the market settles in favor of ‘Up’ or ‘Down’. The opening price will be sourced from a widely recognized financial data provider to ensure accuracy and transparency. Traders will then be able to claim their winnings based on the final outcome.

Several key signals and events could significantly influence this market before Nov 2, 2026. Major economic data releases, such as employment numbers or inflation reports, could shift investor sentiment. Unexpected geopolitical events or company-specific news could also introduce volatility. Furthermore, any statements from the Federal Reserve regarding monetary policy are likely to impact market expectations. Monitoring these factors will be crucial for understanding potential price movements in this market and assessing the evolving probabilities of an upswing or downswing in the S&P 500.
