Nvidia and AMD are pressing the Trump administration, the White House and senior Commerce Department officials to oppose potential China-related chip export restrictions in the annual defense policy bill. The companies argue that overly broad controls could backfire by accelerating Beijing’s push to develop domestic alternatives. The lobbying campaign follows reports that China may allow companies including ByteDance and Alibaba to buy Nvidia’s high-end RTX PRO 5500 chips, while limited batches of H200 processors were approved for mainland China in August. Nvidia’s China-related revenue fell to $4.55 billion in the first quarter from $9.66 billion a year earlier. Senator Elizabeth Warren has called for halting Nvidia’s advanced-chip sales to China and criticized the administration’s relationship with the company. Nvidia and AMD shares were up 22.71% and 183.84%, respectively, year to date, according to Benzinga Pro.
