AI optimism lifts US stocks as oil price and yield worries linger

US equities rose modestly on Friday as AI enthusiasm offset concerns over high oil prices and climbing Treasury yields, with tech shares leading the gains.

Wall Street opened modestly higher on Friday, with the Dow Jones up 0.44%, the S&P 500 up 0.29% and the Nasdaq gaining 0.41%, as AI-related optimism countered fears of higher oil prices and climbing Treasury yields. Microsoft led the rally after unveiling new capabilities in its Copilot app, while chipmakers Micron and Marvell also rose and Nvidia held steady. Oil hovered above $100 a barrel and the 10-year Treasury yield sat at 5.1%, keeping inflation concerns alive amid ongoing Iran and Ukraine conflicts.

A report that US and Iranian negotiators were discussing a phased exit from the war boosted sentiment, though the market remains wary of rising debt and potential Fed rate hikes. Akamai jumped 8% after announcing an $11.6 billion cloud deal with Anthropic, and MGM Resorts was rumored to be eyeing an online-services acquisition. Overall, technology was the only sector to post a weekly gain, offsetting declines in most other S&P 500 groups.
