SPDR S&P 500 ETF Trust (SPY) surged 2.91% to a $650.34 close on March 31, 2026, with an intraday high of $651.54—the week's peak so far—snapping a five-week losing streak amid March's 5.1% monthly decline driven by growth fears, rising oil prices, and geopolitical tensions from Middle East conflicts. Polymarket trader consensus reflects closely contested implied probabilities around 50% for breaching upper thresholds like $655-$665 during the ongoing week of March 30, balancing rebound momentum against potential renewed volatility near the 52-week high of $697.84. Key swing factors include April nonfarm payrolls data and early Q1 earnings from megacaps, which could dictate whether SPY sustains above $650 or tests recent lows around $630.
