President Donald Trump confirmed that Nvidia has agreed to pay the U.S. government 15% of revenue from sales of its China-specific H20 artificial-intelligence chips, reinstating exports that were suspended earlier this year. A similar arrangement applies to Advanced Micro Devices’ MI308 processors, making it the first instance in which Washington has taken an ongoing share of a company’s overseas sales in exchange for export licenses. White House press secretary Karoline Leavitt said the mechanism “stands with these two companies, perhaps it could expand in the future,” adding that the Commerce Department is still ironing out the legality and mechanics of the fee. Trade lawyers note the U.S. Constitution bars export taxes, setting the stage for possible legal challenges. The deal follows weeks of lobbying by Nvidia Chief Executive Officer Jensen Huang. The Wall Street Journal reported that Huang offered to invest up to $500 billion in U.S. facilities as a sweetener after Trump initially floated a 20% levy before settling on 15%. Beijing has responded by urging state-linked firms to avoid Nvidia’s H20 chips, calling them insecure, while U.S. national-security hawks warn that even scaled-down processors could aid China’s military AI ambitions. Nvidia, which derives roughly 40% of its data-center revenue from China, slipped about 0.5% in early trading after the announcement.
