Some U.S. are holding up efforts to finalize a deal that would let the UAE buy billions of dollars of Nvidia’s AI chips due to national-security concerns.

President Donald Trump said late Tuesday that new tariffs on semiconductors could be coming soon. Wedbush analysts said his stance could soften.

Nvidia has profited enormously from rapid adoption of AI, but the trade rivalry between the U.S. and China has been weighing heavily on the industry.

Donald Trump’s decision to let Nvidia sell powerful artificial intelligence (AI) microchips to China has sparked fears that the technology could be used to boost Beijing’s military. Charles Parton, from the think tank Rusi, said there would “inevitably” be sales of semiconductors “which have the possibility of military use”.
