Polymarket traders have coalesced around a 99.6% implied probability of negative Q1 S&P 500 performance, driven by the ongoing U.S.-Iran conflict that has surged crude oil above $110 per barrel since early March, reigniting inflation fears and hammering equities. As of the March 27 close, the index stood at 6,369—down nearly 7% year-to-date from December 31's 6,846—after breaching its 200-day moving average amid five straight losing weeks, the worst since the war began. Surging energy costs threaten corporate margins, while heightened volatility (VIX above 30) reflects risk-off sentiment. With only March 28 and 31 trading days left, a 7.5% rally to breakeven appears improbable barring sudden de-escalation or cooler-than-expected PCE inflation data.

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).
