US stock indices hit record highs following AI chipmaker rally

The S&P 500 and Nasdaq closed at record highs on October 6, 2026, driven by a rally in artificial intelligence chipmakers and a drop in United States treasury yields, the Guardian, Reuters, London South East, Share Talk, and TradingView reported. The Guardian noted that the S&P 500 gained 0.58 percent to surpass 7,800 points for the first time in its history. [1][2][3][4][5]

The Guardian reported that the tech-heavy Nasdaq index rose 0.45 percent during the session, while the Dow Jones Industrial Average climbed 0.49 percent. The Dow remains slightly below the record high that it achieved in August. [1]

The Nasdaq exchange is operated by Nasdaq Incorporated and lists more than 3,000 companies. Its broad composite index tracks domestic and international common stocks listed on the platform, while the Nasdaq-100 index features 100 of its largest non-financial companies. [7]

Reuters and London South East both reported that lower oil prices and cooling treasury yields helped lift stock futures and broader equities throughout the day, while TradingView added that investor attention was also turning toward upcoming earnings reports. [2][3][5]
