<h1><strong>Tech Stocks Tumble as U.S. Export Curbs Could Cost Nvidia $5.5 Billion</strong></h1> Shares of major chipmakers took a hit Wednesday after Nvidia revealed that new U.S. government export restrictions on artificial intelligence (AI) chips could cost the company a staggering <strong>$5.5 billion</strong> in lost revenue. The U.S. government has tightened controls on exports of high-performance chips, particularly those designed for AI applications. Nvidia confirmed that its <strong>H20 integrated circuits</strong> — along with other chips of similar bandwidth — will now require export licenses for an <strong>“indefinite future.”</strong> In a regulatory filing, the company said officials cited concerns that the chips could be used or diverted to <strong>supercomputing projects in China</strong>. The market reacted swiftly: <ul> <li><strong>Nvidia shares fell 5.8% in pre-market trading</strong></li> <li><strong>AMD slipped 6.5%</strong></li> <li>In Asia, key tech players also dropped: <ul> <li>Japan’s <strong>Advantest</strong> fell 6.7%</li> <li><strong>Disco Corp.</strong> declined 7.6%</li> <li><strong>Taiwan Semiconductor Manufacturing Company (TSMC)</strong> lost 2.4%</li> </ul> </li> </ul> The heightened scrutiny comes amid renewed worries over China's growing AI capabilities. In January, the debut of <strong>DeepSeek</strong>, a Chinese AI chatbot, stirred fears in Washington about Beijing’s potential use of advanced U.S. chips in accelerating its own AI development. Senator <strong>Elizabeth Warren</strong> recently urged the <strong>Commerce Department</strong> to clamp down harder on these exports, criticizing what she saw as a pause in the rollout of stricter chip controls. <blockquote> <h3>“I write with great concern regarding reports that the Commerce Department has paused its plan to restrict the export of powerful advanced AI chips like Nvidia’s H20,” Warren wrote in a public letter.</h3> </blockquote> Though the Biden administration previously implemented export controls on advanced AI chips, the H20 model was notably <strong>not included</strong> at the time. In a bold pivot, Nvidia on Monday announced that it will <strong>manufacture its AI supercomputers in the U.S. for the first time</strong>, signaling a major investment in domestic tech infrastructure. The company said it has commissioned <strong>over 1 million square feet</strong> of manufacturing space in <strong>Arizona</strong> (for its specialized <strong>Blackwell chips</strong>) and <strong>Texas</strong> (for AI supercomputers). Nvidia estimates that these efforts could fuel the production of <strong>up to $500 billion worth of AI infrastructure</strong> over the next four years. Former President <strong>Donald Trump</strong> quickly seized on Nvidia’s manufacturing announcement, calling it a win for his push to <strong>expand U.S.-based semiconductor production</strong>. He and other officials had recently discussed plans to shift away from temporary tariff exemptions on electronics and instead develop <strong>industry-specific tariffs</strong> targeting the semiconductor sector. The U.S.-China tech rivalry continues to heat up, especially in the race for AI dominance. With Nvidia caught in the middle, the implications are clear: regulatory moves in Washington are sending shockwaves across global tech markets. As geopolitical tensions rise and export controls tighten, investors and industry leaders alike are watching closely — because in today’s chip wars, every move counts. <em>Source: AP News - <a href="https://apnews.com/article/ai-nvidia-amd-chips-trump-controls-0e6fbdc1ad8b54d8ecc704393c2a1558">Tech shares fall after Nvidia says new US controls on exports of AI chip will cost it $5.5 billion</a></em>
