US stock indices finished lower on Tuesday, dragged down by a broad selloff in semiconductor shares. The S&P 500 slipped 0.4%, the Nasdaq 100 declined 1.8%, and the Dow Jones Industrial Average fell 131 points, retreating from its record high.

Chipmakers were under pressure as investors increasingly questioned whether AI hyperscalers can sustain their current pace of elevated infrastructure spending. Even Samsung’s 19-fold jump in quarterly profit failed to bolster sentiment, which deteriorated further after reports that China’s DeepSeek is developing its own AI chip.

Among major names, Broadcom eased 0.8%, Micron dropped 4.7%, AMD slid 6.5%, and Intel tumbled 9.7%. Nvidia, by contrast, managed a 0.7% gain.

Rising bond yields also weighed on the broader market after attacks on tankers in the Strait of Hormuz reignited worries about energy-driven inflation. In the Dow, Visa fell 1.4%, while Caterpillar declined 3.1%.
