U.S. stock futures and global indexes climbed Thursday, pushing the S&P 500 on track for its longest winning streak since December 2023. The benchmark equity gauge is poised for an eighth straight week of gains as optimism around artificial intelligence, aerospace and other emerging tech fuels demand. Asian and European markets matched the upward trajectory, reflecting broad risk appetite.

The advance persists despite ongoing Middle East tensions, where negotiations between the U.S. and Iran briefly jolted oil markets. Brent crude traded near $105 a barrel, while the 10-year Treasury yield held steady. Investors balance geopolitical uncertainty against the momentum in AI-driven sectors, which continue to attract capital inflows.

The yen weakened past 159 per dollar, nearing levels that may trigger Japanese intervention. SoftBank Group shares surged for a second day, lifting the company’s two-day gain to 34% on AI-related optimism. The currency dip and conglomerate’s rebound highlight how tech sentiment is reshaping investor priorities.

Tech-led gains underscore market resilience even as geopolitical risks linger. The S&P 500’s extended rally reflects confidence in innovation-driven growth, though oil prices and currency moves suggest caution remains.
