Trader consensus on Polymarket prices a subdued maximum single-day S&P 500 gain below 1.5% and loss under 2% for Q1 2024, driven by historically low VIX readings averaging 14 amid resilient U.S. economic data and cooling inflation pressures. The index posted its largest Q1 gain of +1.14% on March 14 following softer CPI figures boosting rate-cut odds, while the steepest drop was -1.68% on January 22 amid banking sector jitters. Robust Q4 earnings from megacaps like Nvidia fueled a 10.2% quarterly rally, dampening volatility. Key watchpoints include lingering Fed dot-plot signals at the March FOMC and April CPI release, which could trigger swings if inflation reaccelerates.

This market will resolve to “Yes” if the price of the S&P 500 Index (SPX) increases by at least the listed percentage on any single trading day between January 14 and March 31, 2026. Otherwise, this market will resolve to “No”.
The percentage change in the S&P 500 Index (SPX) on a given trading day will be calculated by comparing the official closing price for the S&P 500 Index (SPX) on that day to the official closing price for the S&P 500 Index (SPX) on the previous trading day, as reported by the Wall Street Journal. The previous day’s closing price will be subtracted from the current day’s closing price, and then that difference will be divided by the previous day’s closing price. If the daily percentage change is negative, it will be considered a loss of that percentage in absolute terms.
Daily percentage changes will be rounded to two decimal places away from zero (e.g. a daily percentage gain of 1.995% would be considered 2.00%, and a daily percentage gain of 1.993% would be considered 1.99%)
If any relevant trading day 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 a relevant trading day (for example, due to a trading halt into the close, system issue, or other disruption), this market will use the most recent official price published by the specified resolution source as the effective closing price.
The resolution source for this market will be the Wall Street Journal, specifically the daily CLOSE prices for the S&P 500 Index (SPX) published on the S&P 500 Index (SPX) historical prices page (https://www.wsj.com/market-data/quotes/index/SPX/historical-prices).This market will resolve to “Yes” if the price of the S&P 500 Index (SPX) increases by at least the listed percentage on any single trading day between January 14 and March 31, 2026.

The previous day’s closing price will be subtracted from the current day’s closing price, and then that difference will be divided by the previous day’s closing price. If the daily percentage change is negative, it will be considered a loss of that percentage in absolute terms.
Daily percentage changes will be rounded to two decimal places away from zero (e.g. a daily percentage loss of 1.995% would be considered 2.00%, and a daily percentage loss of 1.993% would be considered 1.99%)
If any relevant trading day 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 a relevant trading day (for example, due to a trading halt into the close, system issue, or other disruption), this market will use the most recent official price published by the specified resolution source as the effective closing price.
The resolution source for this market will be the Wall Street Journal, specifically the daily CLOSE prices for the S&P 500 Index (SPX) published on the S&P 500 Index (SPX) historical prices page (https://www.wsj.com/market-data/quotes/index/SPX/historical-prices).This market will resolve to “Yes” if the price of the S&P 500 Index (SPX) decreases by at least the listed percentage on any single trading day between January 14 and March 31, 2026. Otherwise, this market will resolve to “No”.
The percentage change in the S&P 500 Index (SPX) on a given trading day will be calculated by comparing the official closing price for the S&P 500 Index (SPX) on that day to the official closing price for the S&P 500 Index (SPX) on the previous trading day, as reported by the Wall Street Journal.

0x65070BE91...Trader consensus on Polymarket prices a subdued maximum single-day S&P 500 gain below 1.5% and loss under 2% for Q1 2024, driven by historically low VIX readings averaging 14 amid resilient U.S. economic data and cooling inflation pressures. The index posted its largest Q1 gain of +1.14% on March 14 following softer CPI figures boosting rate-cut odds, while the steepest drop was -1.68% on January 22 amid banking sector jitters. Robust Q4 earnings from megacaps like Nvidia fueled a 10.2% quarterly rally, dampening volatility. Key watchpoints include lingering Fed dot-plot signals at the March FOMC and April CPI release, which could trigger swings if inflation reaccelerates.
