U.S. Congressman Bets Thousands on Chinese Big Tech and AI Semiconductors: Here's Why

U.S. Representative Gil Cisneros (D–California) disclosed in a March 9 transaction report that he purchased tens of thousands of dollars’ worth of shares in Chinese tech giant Alibaba and U.S. AI semiconductor firm AMD in early February. According to the filing, on February 9 Cisneros acquired between $51,000 and $100,000 of Alibaba Group Holding Limited (BABA) American Depositary Shares (ADS), and on February 10 he bought between $1,001 and $15,000 of Advanced Micro Devices, Inc. (AMD). He also made smaller purchases of Amazon, Boston Scientific and Champion Homes shares.

Alibaba Group Holding Limited is one of China’s leading e-commerce and cloud computing companies. More recently, it has been revalued as a “Chinese AI platform,” thanks to its AI-powered cloud services and generative AI models. However, Alibaba’s share price has been volatile: after Cisneros’s February 9 purchase at a closing price of $163, the stock fell about 16% to $136.29 by March 11, amid heightened Chinese e-commerce regulation, sluggish cloud growth, renewed platform oversight by Chinese authorities and reports that Alibaba was again listed in the U.S. Department of Defense’s update of “Communist Chinese Military Companies.” (Source: stockanalysis.com.) Given Congress’s longstanding focus on China-related security risks, a substantial investment in Alibaba by a sitting member of the House is certain to invite political scrutiny.

Advanced Micro Devices has emerged as a core player in the U.S. strategy for semiconductors and AI infrastructure, challenging NVIDIA in data-center CPUs, GPUs and AI accelerators. In its fiscal fourth quarter ended December 2025, AMD reported double-digit revenue and profit growth, but its conservative guidance for the first quarter left investors disappointed and drove the shares down more than 20% immediately after the earnings release. The stock then rebounded about 7% on February 6. (Source: AMD Q4 2025 Earnings Slides.) Shortly thereafter, media reports of a multi-billion-dollar, long-term deal to supply Meta with up to 6 gigawatts of AI GPUs—complete with performance-linked warrants—reinvigorated the AI data-center growth narrative. Nevertheless, AMD’s closing price on March 11 was $204.83, roughly 4% below the $213.57 closing price on Cisneros’s February 10 purchase date, underscoring the market’s alternating optimism and caution over the AI investment cycle.

Cisneros, a former Navy officer, serves on the House Armed Services Committee and the Small Business Committee, with assignments on the Intelligence and Special Operations; Military Personnel; Federal Procurement, Technology and Infrastructure; and Regulatory Reform, Commercial and Antitrust Law subcommittees. He has championed defense and veterans’ support as well as strengthening U.S. manufacturing and technological competitiveness. By investing sizable sums in both a major Chinese tech platform and a leading U.S. AI semiconductor company—key players on opposite sides of the U.S.–China technology rivalry—he raises potential conflict-of-interest questions regarding his legislative and oversight duties. Congress is already considering bipartisan bills to ban members (and their families) from individual stock trading or to require blind trusts, and public polls show overwhelming support for prohibiting congressional stock trades.

In this environment of intensifying regulatory debate, Cisneros’s personal positions in Alibaba and AMD—both directly linked to defense, technology and China policy—could become a focal point for future ethics and regulatory battles.
