According to media reports citing informed sources, U.S. officials have drafted a regulatory proposal aimed at restricting the shipment of artificial intelligence chips globally without U.S. approval. The bill would grant Washington broad powers to determine whether other countries can build facilities for training and running artificial intelligence models and under what conditions. The proposed regulation would require companies to apply for a license from the U.S. to export nearly all AI accelerators produced by companies like Nvidia and AMD. This would expand the current regulatory measures, which cover about 40 countries, to a global scale. Former U.S. President Trump has repeatedly stated that he wants the world to use American artificial intelligence, and the purpose of the draft is not to ban Nvidia's exports. Instead, this regulation would position the U.S. government as the "gatekeeper" of the AI industry: companies (and in some cases, their home governments) must obtain approval from the U.S. Department of Commerce to purchase accelerators. The second-ranked Tesla fell by 2.17%, with a trading volume of $25.299 billion. The company's CEO, Elon Musk, testified that he believed the false account data was underestimated. Investors accused him of suppressing Twitter's stock price with tweets made prior to the acquisition in 2022. The third-ranked Broadcom fell by 0.69%, with a trading volume of $12.863 billion. After the company announced its earnings, Wall Street analysts praised the chip and software giant's "strong" outlook for 2027, indicating that the company would continue to invest heavily in the AI sector. Jefferies analyst Blayne Curtis wrote in a report to clients: "The AI market is expected to exceed $100 billion in fiscal year 2027, which may be overly conservative, as Broadcom expects to provide 10GW of computing power, including over 1GW to its sixth announced customer, OpenAI. The situation of excess AI spending will continue, but Broadcom has clearly demonstrated that its AI revenue will exceed market averages and maintain sustained growth before 2028." Curtis rated Broadcom as "Buy," with a target price of $500. The fourth-ranked Micron fell by 6.74%, with a trading volume of $12.8 billion. The stock has accumulated a decline of over 10% this week. UBS analyst Timothy Arcuri is highly optimistic about Micron's prospects, predicting that Micron's EPS for the calendar year 2027 could challenge $85, far exceeding the market average expectation of $48. Arcuri noted that due to the demand for artificial intelligence (AI), the supply of memory has tightened, leading companies like Micron to gradually raise component prices. He believes that Micron may actively negotiate new long-term agreements due to this trend, although this will give up some recent price increase space, but these agreements should help support more robust revenue and profits in the coming years. Arcuri further analyzed that the pricing momentum for DRAM and NAND is continuing to strengthen, and the supply shortage may persist until 2028 Ranked 6th, Palantir rose by 2.94%, with a trading volume of $11.68 billion. The stock has accumulated an increase of about 15% this week. The price increase today was driven by a series of positive factors: a court victory protecting its intellectual property and employees, new analyst support, and renewed investor interest in the defense/AI sector amid geopolitical tensions. Counterbalancing these positive factors are the costs and uncertainties arising from the Pentagon's controversy with Anthropic, as well as insider selling mentioned in some headlines, which have kept the stock price highly volatile. The court victory strengthened Palantir's intellectual property and talent protection—recently unsealed documents show that the judge prohibited former employees from using Palantir's proprietary data and poaching employees, thereby reducing competition and operational risks, which helps explain the stock price increase. Piper Sandler reiterated its "Overweight" rating and a target price of $230, while other firms also raised their target prices or earnings expectations, supporting the bullish outlook for the stock. Ranked 9th, SanDisk fell by 6.76%, with a trading volume of $8.744 billion. The stock has accumulated a decline of 17% this week. The well-known short seller Citron Research recently announced a short position on the stock, claiming that there is a fundamental error in the market's pricing logic for SanDisk, and that the current tight supply of storage chips is merely an "illusion," with the cycle peak just around the corner. Ranked 11th, Marvell Technology rose by 18.35%, with a trading volume of $7.859 billion. The company's fourth-quarter revenue exceeded Wall Street expectations and provided a strong sales forecast for the next quarter. In the fourth quarter of the 2025 calendar year, the company achieved revenue of $2.22 billion, a year-on-year increase of 22.1%, slightly above analyst expectations. The company's adjusted earnings per share were $0.80, in line with market expectations. The main driver of the positive investor response seems to be the company's optimistic outlook for the first quarter of 2026. Management forecasts a midpoint revenue of $2.4 billion for the quarter, significantly higher than the analyst expectation of $2.28 billion, indicating sustained strong demand for its chips used in data centers and communication networks. Ranked 13th, AMD fell by 3.52%, with a trading volume of $6.462 billion. The stock has accumulated a decline of about 3.9% this week. Ranked 16th, Lumentum Holdings fell by 14.19%, with a trading volume of $5.006 billion. The stock has accumulated a decline of over 20% this week. Earlier this week, NVIDIA announced that it would invest $2 billion each in optical technology companies Lumentum and Coherent under multi-year agreements. NVIDIA's non-exclusive agreement with Coherent includes multi-billion dollar procurement commitments and future capacity rights for advanced laser components, while NVIDIA will support Lumentum's R&D, future capacity, and operations, aiding its new wafer fabrication facility in the U.S Taiwan Semiconductor Manufacturing Company (TSMC) closed down 4.23%, with a trading volume of $4.686 billion. The stock has accumulated a decline of 9.5% this week.
