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).

The Trump administration’s deals with Nvidia and Advanced Micro Devices to take a cut of their AI chip sales in China are certainly unusual. But for a profit machine like Nvidia, they may not move the needle.
