What will S&P 500 (SPX) close at in January?

Market Overview

Markets are sorted by active status and volume. Probability history is fetched from Polymarket CLOB for the top market token IDs, similar to Bitcoin.com Markets.

Event Description

This market will resolve according to the official closing price for S&P 500 (SPX) on the final trading day of January 2026. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. If the final trading day of the month is shortened (for example, due to a market-holiday schedule), the official closing price published for that shortened session will still be used for resolution. If no official closing price is published for that session (for example, due to a trading halt into the 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 Yahoo Finance, specifically the S&P 500 (SPX) "Close" prices available at https://finance.yahoo.com/quote/%5EGSPC/history, published under "Historical Prices."
