S&P 500, Nasdaq futures climb to record highs on trade optimism

Shares of technology heavyweights rose premarket after Canada scrapped its digital services tax targeting U.S. tech firms, just hours before it was due to take effect, in a bid to advance stalled trade negotiations with the United States. The benchmark S&P 500 and the tech-heavy Nasdaq Composite rose to all-time highs on Friday, as bets of deeper U.S. interest rate cuts and renewed optimism around AI helped markets rebound from the months-long tumult sparked by U.S. President Donald Trump's tariff policies and geopolitical tensions.
