US stocks: US market ends up on Iran war peace deal hopes, SpaceX's historic debut

US equity indices ended higher on Friday, with the S&P 500 up 0.51% at 7,431.83, Nasdaq gaining 0.30% to 25,887.43, and Dow Jones rising 0.71% to 51,208.20, driven by hopes of an Iran peace deal that eased oil price and inflation concerns. The rally coincided with SpaceX's historic market debut, which briefly made Elon Musk the world's first trillionaire, though the company posted over $4 billion in annual losses. Investors also looked ahead to next week's Federal Reserve policy meeting, the first under new chair Kevin Warsh, while Adobe declined after its CFO exit and US equity funds recorded their first weekly outflow in three weeks.
