US stock market today: S&P 500, Nasdaq futures zoom up to 2% as US-Iran peace deal sinks oil prices; SpaceX up 5.5%

US stock futures surged on Monday after the US and Iran reached a peace deal to end a nearly four-month Middle East conflict, with S&P 500 futures up 1.2%, Nasdaq 100 futures up 2%, and Dow futures up 0.8%. Crude oil prices tumbled to multi-month lows, with Brent crude falling nearly 5% to $83/barrel and WTI dropping 5.35% to $80.34/barrel, as the Strait of Hormuz is set to reopen by Friday. The lower oil prices are expected to ease inflation pressures and may give central banks, including the Federal Reserve, more room to cut interest rates, while SpaceX's strong Nasdaq debut (closing 19% above issue price) reinforced AI-driven rally sentiment.
