The Nasdaq 100 rose above the 30,000-point mark for the first time on Tuesday, driven by renewed enthusiasm for artificial intelligence stocks and hopes of progress in talks aimed at ending the Iran war.
The tech-heavy index gained 1.76% to close at 30,001.32 points, while the broader S&P 500 rose 0.61% to a record 7,519.12.
The Dow Jones Industrial Average lagged behind, slipping 0.23% to 50,461.68 points and remaining below the record high it reached on Friday.
Investor sentiment was supported by expectations of a possible framework agreement related to the Iran conflict, despite renewed attacks in Iran and Lebanon overshadowing negotiations. One market observer said the military confrontation still appeared to leave both sides closer to an agreement than they had been recently.
Technology shares, particularly chipmakers, once again led gains after investors had recently shifted attention toward Asian and European sector peers.
Shares linked to the space industry also rallied, fuelled by anticipation surrounding the upcoming blockbuster initial public offering of Elon Musk's rocket company SpaceX, traders said. Space companies including MDA Space, Firefly Aerospace and Redwire rose between 4% and 26%.
