Congress is moving to strip the executive branch of its power to approve advanced chip sales to China, directly challenging both Nvidia and the Trump administration's approach to AI competition. The House Foreign Affairs Committee advanced legislation that would give lawmakers the ability to review and block semiconductor exports to adversarial nations, similar to how Congress oversees weapons sales. The effort has exposed a rare fault line within the Trump administration itself, with Republican lawmakers accusing the White House AI czar of parroting Nvidia's talking points. Why Is Congress Taking On Nvidia Over China Chip Sales? House Foreign Affairs Committee Chairman Brian Mast, a Republican from Florida, frames the issue as a matter of national security in an era of AI-driven military competition. He argues that advanced semiconductors should be treated as weapons, not commercial products, when they could enhance China's military capabilities. "We are in an AI arms race, and it's important that we know where the AI arms dealers are selling," Mast stated. The legislation would require Congress to have 30 days to review and potentially block chip sales to countries like China. It would also cancel all existing export licenses until the government submits a detailed strategy explaining how the chips would affect military and intelligence operations. The bill passed the House committee with overwhelming bipartisan support, with all but two members voting in favor. Mast directly challenged Nvidia CEO Jensen Huang's repeated pitch to lawmakers that allowing more U.S. chip sales to China actually benefits American companies by maintaining market leadership. "The joke here is, Jensen wants us to trust the CCP," Mast told CNBC, referring to the Chinese Communist Party. "Anybody watching this should laugh". What's Nvidia's Position on Export Controls? Nvidia has consistently argued that the risk of its chips being used by the Chinese military is minimal. The company stated that "it makes no sense for the Chinese military to depend on American technology," suggesting that Beijing would never rely on U.S. semiconductors for critical military systems. The company also warned that restricting chip exports could backfire strategically. Nvidia argued that "the administration's critics are unintentionally promoting the interests of foreign competitors," and that America should want its industry to compete for approved commercial business to protect national security and maintain technological leadership. Nvidia However, Nvidia faces a more immediate problem: it still hasn't generated any revenue from the chips it was approved to sell to China. Despite the Trump administration allowing sales of the more advanced H200 chip to China in December 2025, provided the U.S. government receives 25 percent of sales revenue, actual shipments have stalled. "While small amounts of H200 products for China-based customers were approved by the US government, we have yet to generate any revenue," Nvidia's Chief Financial Officer Colette M. Kress said on an earnings call. How Are Export Controls Actually Structured? The current system involves multiple layers of complexity that have created bottlenecks. Chips destined for China must be routed from Taiwan, where they are manufactured, to the United States for independent third-party testing before being exported. This process, combined with security scrutiny from both Washington and Beijing, has effectively frozen sales despite government approval. The revenue-sharing arrangement itself faces legal challenges. Legal experts argue that the 25 percent tax on chip exports violates the Export Control Reform Act (ECRA), which explicitly prohibits the government from charging fees in connection with export licenses. The arrangement also raises constitutional concerns about taxation without congressional authorization, since the power to impose taxes belongs exclusively to Congress. Steps to Understanding the Policy Dispute - Congressional Authority: The House bill would give lawmakers the same 30-day review power over chip exports that they currently have over weapons sales, fundamentally shifting decision-making from the executive branch to Congress. - National Security Framing: Supporters argue advanced semiconductors should be classified as national security assets because they enable military AI systems, artificial intelligence algorithms that power defense applications. - Commercial Competition: Nvidia contends that restricting exports helps Chinese competitors develop alternatives, potentially ceding long-term market dominance to Beijing-backed chipmakers. - Legal Challenges: The Trump administration's revenue-sharing scheme faces potential court challenges on grounds that it imposes unauthorized taxes and violates statutory prohibitions on export licensing fees. What's Driving the White House Opposition? The Trump administration's AI czar, David Sacks, publicly opposed the congressional bill before the House committee vote. He retweeted criticism arguing that the legislation "handicaps Trump's ability to strategically position the USA favorably against China." Mast fired back, accusing Sacks of amplifying "mercenary influencers" who were repeating Nvidia's talking points. The disagreement reflects competing visions within the administration. Some officials prioritize maintaining Nvidia's market access as a way to keep American companies dominant in AI, while others view any chip sales to China as a strategic mistake that strengthens a geopolitical rival. The fact that a Republican chairman is publicly criticizing a Trump appointee suggests the debate has moved beyond typical partisan lines. Why Is Nvidia Worried About Chinese Competitors? Nvidia's concerns about losing market share are not hypothetical. Chinese AI chipmakers have gained significant momentum through recent initial public offerings (IPOs) in Hong Kong and mainland China. Companies like MiniMax and Moore Threads have seen their stock prices surge as investors bet they could become viable alternatives to American AI technology. While Chinese AI companies still lag slightly behind U.S. capabilities, their products are typically far cheaper. This price advantage could prove decisive in global markets where cost matters more than cutting-edge performance. "Our competitors in China, bolstered by recent IPOs, are making progress and have the potential to disrupt the structure of the global AI industry over the long-term," Kress warned investors. Some analysts believe the shift could be dramatic. Rory Green, chief China economist at TS Lombard, suggested that "you could see easily a world where maybe most of the world's population is running on a Chinese tech stack in five to 10 years' time". What Happens Next? The House bill faces an uphill climb to reach the full chamber floor despite its committee support. The White House opposition and Nvidia's lobbying efforts create significant obstacles. However, the legislation has a companion bill in the Senate with bipartisan backing from Republican Jim Banks and Democrat Elizabeth Warren, suggesting the effort has broader congressional support. Mast is also planning a separate vote on the Chip Security Act, which would require exported advanced chips to contain a mechanism verifying their location and would mandate that exporters alert the government if a chip ends up in an unauthorized location. This bill also has bipartisan support in both chambers. The fundamental question remains unresolved: Should the executive branch have the flexibility to negotiate chip sales as a strategic tool, or should Congress maintain explicit control over exports to potential adversaries? The answer will shape not just Nvidia's business prospects, but America's long-term position in the global AI competition.
