Trump said Monday that he has cut a deal with chipmaker Nvidia, allowing it to sell certain artificial intelligence chips to China in exchange for a cut of the revenue, which would go to the U.S. government. Trump said he also negotiated a similar deal with chipmaker Advanced Micro Devices (AMD).

Nvidia struck a surprising deal after convincing the president that H20 chips aren’t a national security risk. But whether the reversal is good or bad depends on who you ask.

Outside of the U.S., China remains one of the most important markets fueling demand for high-performance chipsets, particularly graphics processing units (GPUs). Nvidia CEO Jensen Huang has estimated that the AI opportunity in China alone could be worth as much as $50 billion.
