US stock market today: Wall Street futures gain as easing oil prices offset lingering Middle East tensions

US stock futures traded higher on Monday with S&P 500 futures up 0.5% and Nasdaq-100 futures up 1% as crude oil prices retreated from intraday highs on signs of renewed US-Iran diplomatic efforts. Brent crude slipped to around $87 per barrel and WTI to about $80 per barrel after briefly touching $91 and $85 respectively. Geopolitical tensions remain elevated, with Iran firing missiles toward Jordan and the US extending attacks on Iranian infrastructure, while the Philadelphia Semiconductor Index entered bear market territory with a 20% decline from its June peak amid concerns over stretched AI valuations.
