The chipmaker, now the most valuable public company in the world, said strong demand for its chips should continue this quarter.

Jensen Huang, Nvidia’s chief executive, said he plans to ask the Trump administration’s permission to sell a more powerful chip to Chinese companies.

President Trump has become the semiconductor sector’s leading decision maker, from new fees on exports to China to a brief demand for a C.E.O.’s firing.

A deal for Nvidia and AMD to give the Trump administration a cut of chip sales to China raises questions about national security and trade policy goals.

In a highly unusual arrangement with President Trump, the companies are expected to kick 15 percent of what they make in China to the U.S. government.

The president’s trade war entered a new phase on Thursday with hefty levies on scores of countries taking effect, adding further uncertainty.

With help from a longtime Silicon Valley investor turned White House insider, Mr. Huang got the administration to reverse course on restrictions.

Jensen Huang, the chipmaker’s chief executive, is trying to balance his company’s interests as the United States and China compete for supremacy in artificial intelligence.

The A.I. chip maker reached the landmark before Apple and Microsoft, as its value rose more than tenfold after ChatGPT’s release in late 2022.
