Nvidia shares fall 1.30% premarket on potential US export controls and China sales cap at 75,000 units

Nvidia shares fell 1.30% in premarket trading after Bloomberg reported the US government is weighing new export control measures for AI chips. The Trump administration, through the Commerce Department, is considering rules requiring approval for all chip exports, with shipments of up to 1,000 GPUs facing a simplified process while orders above 200,000 units would need licenses, which could also affect AMD. US authorities have placed Alibaba on an entity list and are reportedly planning to cap Chinese customers' purchases of Nvidia chips at 75,000 units, with similar AMD shipments counted toward that limit. Despite China-related revenue pressures, Nvidia reported fourth-quarter revenue of $68 billion, exceeding guidance by $3 billion, with its share price trading between $170 support and $197 resistance.
