This market will resolve to "Yes" if the official closing price for S&P 500 (SPX) on the final trading day of March 2026 is higher than the listed price. Otherwise, this market will resolve to "No". 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 recorded price in March 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."The S&P 500 index closed March 30 at 6,343.72, down 0.39% for the day and approximately 2.8% over the past week, reflecting trader concerns over escalating Middle East tensions—now in their fifth week—involving Iran, which have driven the benchmark to seven-month lows. This pullback erased gains from mid-March highs near 6,500, amid rising Treasury yields pressuring equity valuations and mixed economic signals, including recent labor market resilience tempering expectations for aggressive Federal Reserve rate cuts. Today's key releases include the S&P Case-Shiller 20-city home price index at 9:00 a.m. ET, potentially swaying housing-related stocks ahead of quarter-end positioning and the March 31 close that resolves end-of-month thresholds. Elevated volatility underscores the closely contested positioning near critical levels.
