Polymarket's trader consensus assigns a 99.5% implied probability to negative Q1 S&P 500 performance, driven by the index's roughly -7% year-to-date decline as of the March 27 close at 6,369—down from 6,846 on December 31, 2025—with resolution imminent today. Escalating Middle East tensions, particularly the Iran conflict, have spiked oil prices and reignited inflation fears, pushing recession odds to multi-year highs in Moody's model and prompting a broad selloff that erased January gains. Large-cap underperformance amid rising Treasury yields and softer jobs data has cemented the downtrend, though Q1 earnings growth is still projected at 12%. A challenge would require an unprecedented single-day rally exceeding 7%, contingent on sudden de-escalation or positive macro surprises.

The percentage change in the S&P 500 Index (SPX) in the specified quarter will be calculated by comparing the official closing price for the S&P 500 Index (SPX) for the final trading day of the quarter to the official closing price for the S&P 500 Index (SPX) for the final trading day of the previous quarter, as reported by the Wall Street Journal. The closing price for the final trading day of the previous quarter will be subtracted from the closing price for the final trading day of the specified quarter, and then that difference will be divided by the closing price for the final trading day of the previous quarter.
Percentage changes will be rounded to two decimal places away from zero (e.g. a percentage change of 4.995% would be considered 5.00%, and a percentage change of 4.993% would be considered 4.99%)
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.
If the percentage change in the S&P 500 Index (SPX) in the first quarter of 2026 falls exactly between two listed brackets, this market will resolve to the higher bracket.
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).
