Nvidia CEO Jensen Huang sold 75,000 shares on Friday, valued at about $12.94 million, according to a filing with the U.S. Securities and Exchange Commission. 

Friday’s sale is part of a plan adopted in March for Huang to sell up to 6 million shares of the leading artificial intelligence company. Earlier this week, Huang sold 225,000 shares of the chipmaker, totaling about $37 million, according to a separate SEC filing. The CEO began trading stock per the plan last month.

Surging demand for AI and the graphics processing units that power large language models has significantly boosted Huang’s net worth and pushed Nvidia’s market capitalization beyond $4 trillion, making it the world’s most valuable company.

Nvidia announced this week that it expects to resume sales of its H20 chips to China soon, following signals from the Trump administration that it would approve export licenses. Earlier this year, U.S. officials had stated that Nvidia would require special permission to ship the chips, which are specifically designed for the Chinese market.

“The U.S. government has assured NVIDIA that licenses will be granted, and NVIDIA hopes to start deliveries soon,” the company said in a statement on Tuesday. Huang said during a news conference on Wednesday in Beijing that he wants to sell chips more advanced than the H20 to China at some point.
