Trump purchased up to $5m of stock before revoking Biden-era rule that limited Nvidia’s ability to sell to China

Donald Trump bought Nvidia stock worth millions of dollars as he made decisions on America’s China policy that would benefit the chipmaker, an analysis has found.

In May 2025, Trump’s administration rescinded a Biden-era rule designed to prevent the most advanced US-made AI chips from being exported to China.

This rule aimed to strengthen the US’s own chip industry and to protect America from what was widely regarded as a national security threat: the possibility that China might develop superior AI.
