Chip stocks fall as U.S.-China summit yields no major tech deals, Nvidia breakthrough

Global semiconductor shares slid after a May 15, 2026, summit between President Donald Trump and Chinese leader Xi Jinping ended without major technology agreements or progress on Nvidia Corp.’s ability to sell chips in China. The outcome disappointed investors looking for signs of easing U.S.-China tech restrictions, particularly around advanced semiconductors used in artificial intelligence. Nvidia’s China sales remain a key market focus as Washington’s export controls continue to shape demand expectations across the chip sector.
